Getting the most from excavator technology Recent technological improvements in 19- to 50-metric ton excavators have taken the operator experience to a new level, but have left some unanswered questions about the real benefits of these features and how to address the knowledge gap among operators.

How to Select a Hammer Although hydraulic hammers, or breakers, are some of the most frequently used attachments in construction, they are also among the least understood. One equipment manager shares the processes he used to select hammers, and how he maximized ROI after purchase.

Concrete Control Uniformity makes all the difference for quality concrete pavement mixes, and it begins with properly managing the aggregate.

Skills training for the first seven jobs

L

ast month, the hashtag #firstsevenjobs was trending on Twitter. The idea was to list, using the social media medium of your choice, the first seven jobs you had in your life – all those lawn mowing and waitressing gigs that first made you flush with pocket change.

Since I’ve interviewed my share of contractors, I’m going to take a stab at creating such a list for a mythical contractor: 1. Go-fer 2. Laborer 3. Mechanic’s helper 4. Equipment operator 5. Estimator 6. Crew foreman 7. Job superintendent The career path here is apparent, but on such a list there’s no indication of what type of training is needed to move forward. How exactly do you get from go-fer to equipment operator or job superintendent? What type of training and experience do you need?

Well, it depends. Company A may place a premium on formal education, while company B pays special attention to a worker’s communication skills. And the type of work a contractor does will influence this list. For example, Mike Brock with Brock’s Grading & Landclearing in Hartsville, South Carolina, says he would love to see someone who has a knowledge of different soil conditions, grades and topography. And it wouldn’t hurt for them to understand GPS. Fortunately, educational alternatives that have always been around are gaining new respectability. As NPR’s Marketplace

show reported last month, “Skills training is having a moment.” The show quoted the National Skills Coalition, which promotes training for what it calls “middle skills” jobs – those requiring more than high school but less than a four-year degree. According to the coalition, these middle skill jobs make up 54 percent of the jobs in the U.S. economy, but only 44 percent of U.S. workers are trained to the middle skill level.

As construction relies more on technology, the skills disconnect can be more pronounced. I was struck by Mike Momrow’s comments in the GPS/GNSS 101 story in this issue. As survey manager for Rifenburg Companies in Troy, New York, Momrow makes the declaration that his company “doesn’t use GPS, it runs on GPS.” And therein lies the skills gap: “We just don’t have enough machine control or survey guys who can take the technology and run with it,” he told Executive Editor Tom Jackson. “There’s not a college in the United States that teaches machine control technology,” he says. “You still have to learn that on the job.”

OTJ training will always be a major part of how skills are transferred in this industry.

There’s no classroom that can replicate the see-this/know-this immediacy of how to handle a job-specific task. But that shouldn’t be an excuse for the catch-as-catch-can education that too many contractors rely on to make sure their valued crews are gaining the skills they need to advance.

If skills training is indeed having a moment, right now might also be a good backto-school moment.

Nominations open for Equipment World’s Contractor of the Year contest

T

he Equipment World Contractor of the Year contest, which honors 12 finalists each year, is now open for nominations.

Designed to honor contractors who have excelled in their markets, the contest is open to construction firm owners who have been in business 10 years or more, have between $3 million and $15 million in annual revenues, and have an excellent safety record.

Each finalist and their guest will receive an expenses-paid weekend in Las Vegas, courtesy of Caterpillar, which has sponsored the program for the past 17 years. The event includes an industry roundtable, focus group, awards banquet, and a day at the Las Vegas Motor Speedway watching the NASCAR Kobalt 400. All finalists will stay at the premier Wynn Resort on the Las Vegas strip.

This year’s event has the added bonus of being held during the final two days of ConExpo-Con/Agg 2017, the construction equipment industry’s premier trade show, held every three years.

“The Contractor of the Year event was an enormous occasion to be

exposed to different ways of thinking, interesting uses of resources, and best practices that added new perspective to our own dealings,” say this year’s winners, Greg and Dawn Tatro of G. W. Tatro Construction in Jeffersonville, Vermont. “The roundtable was a highlight for us, since we felt that not only did we learn from contractors at the table, but also that we were able to contribute ideas that might be appreciated by our peers, as well.”

Contractors have until September 30, 2016 to apply to the program. The first 50 applicants will receive a free Cat hat. To enter, go to EWcontractoroftheyear.com, and click on the “Apply Now” button. You can either enter online with a convenient form, or download an application form to print and fill out later. In addition to the information on the form, applicants are welcome to submit up to three supporting pieces of information such as newspaper clips, or copies of awards and client reference letters.

Briefs Ritchie Bros. has bought Petrowsky Auctioneers, based in North Franklin, Connecticut. Petrowsky was founded nearly 40 years ago by Sammy Piotrowski, and operated primarily in New England.

With a fiscal year that starts April 1st, Komatsu reported first quarter sales decreases of 13 percent. In its reporting, the company cited continued low demand from the mining industry, weaker demand from Chinese construction customers, and the strength of the Japanese yen as reasons behind this decrease. Komatsu says it expects this fiscal year’s profits to fall 33 percent from the previous year.

JLG says its doubled the length of engine service intervals – from 500 to 1,000 hours – on its JLG and SkyTrak telehandlers equipped with Cummins QSF3.8 diesel engines. The use of synthetic oil, plus new oil and fuel filters, led to the extension.

The company still recommends an initial oil change take place at 500 hours.

Asphalt plant manufacturer and Roadtec parent company Astec has reported a net sales increase of 9.9 percent in the second quarter, compared to the same quarter last year. The company says the primary reason for the increase was demand resulting from passage of the Fixing America’s Surface Transportation (FAST) Act last year, in addition to increased private sector activity.

Terex’s second quarter profits fell 8 percent, while net sales decreased 10 percent. In June, Terex announced the sale of its compact construction segment to Yanmar and consolidated its corporate structure from five segments to three.

aerial work platform segment’s sales fell 14 percent during the quarter, while crane sales fell 16 percent.

Caterpillar has once again cut its outlook for 2016, following second quarter sales declines of 16 percent. The firm now says it expects its total sales for the year will be between $40 billion and $40.5 billion.

CNH Industrial, maker of Case and New Holland equipment, saw a 5 percent increase in profits in the second quarter, and a net sales decline of 3 percent. The company’s construction equipment segment’s sales fell almost 20 percent during the quarter, blamed on lower demand in North America.

Mid-range loaders get large-loader features JCB is upgrading its mid-range wheel loader range, introducing several larger loader features in its 411, 417, 427 and 437 models.

These features include JCB’s CommandPlus Cab and CommandPlus Control system, Tier 4 Final engines that do not have a diesel par-

ticulate filter, and a range of loader arms to suit various applications.

The 108-horsepower 411 and the 125- horsepower 417 models are powered by JCB EcoMAX engines. The larger 179-horsepower 427 and 183-horespower 437 models have Cummins engines.

Lift two wall barriers at a time Kenco’s new Dual Lift attachment can lift and move two barrier walls at a time and is fully automatic for hands-free operation. The Dual Lift can grip a barrier when it is set down; it releases only when it has been placed into position.

A sling and shackle assembly is required for hook up. The attachment’s design includes alignment legs extending from one side to allow the operator to guide it onto the barrier. Swiveling pad angles match the slope of the barrier, and the elastomer pads securely grip the barriers wet or dry.

GETTING THE MOST FROM

EXCAVATOR TECHNOLOGY

Deere refers to the three modes of its Powerwise III system as “productivity modes.” Among the available features on the John Deere 300G LC is a thumb attachment mode. Oil flow for thumb attachments is controlled through the monitor.

22 September 2016 | EquipmentWorld.com

Excavators from 19- to 50-metric tons are brimming with technology, from electronic controls to hyper-adjustable seating. But, questions still abound about how this technology benefits the contractor, and especially how contractors can learn to get the most from these features.

A la mode Excavators have multiple modes, multiple names for those modes, and those modes provide varying degrees of control by the operator. Some modes refer to the performance of the machine, such as Power and Eco. Other modes refer to the task at hand, such as Dig and Lift.

Some are more descriptive, such as Boom Economy Control in the Case Intelligent Hydraulic System, which cuts engine speed during boom down and swing gravity functions. Others simply use letters or numbers – “A” and “H” for example – and rely on the operator to know which mode delivers the right performance characteristics for the work being done.

Then, there are modes for attachments. Some excavators can be programmed for up to 20 attachments, with each programmed setting named by the operator. In some modes, the operator cannot change any settings.

In others, such as the programming of attachments, the operator has a somewhat free hand to set engine

speed, as well as hydraulic flow and pressure.

Accessing modes and other machine controls is not at all standardized. Some OEMs still use traditional switches. Others make options accessible through the in-cab monitor. Still others have adopted haptic controllers from the automotive world.

Haptics is the term for tactile feedback; a pivotal part of the discussion as OEMs move from pilot control valves to electrohydraulic controls. A haptic controller is typically one with a knob that turns to select options on a monitor or other display; the operator then presses the controller to click on (or select) the highlighted item. There are currently questions as to whether haptic controls give the same feel and feedThe Doosan DX225LC-5 has four works modes and four power modes. Power modes can be run with or without Smart Power Control (SPC), which improves efficiency and performance. SPC is available only in Digging work mode.

The LiuGong 922E has six work modes: Power, Economy, Fine, Lifting, Breaker, and Attachment. IPC (Intelligent Power Control) matches engine and hydraulic output for improved performance and efficiency.

back as pilot controls, much like the discussion when the transition was made from mechanical controls to pilot controls.With so many modes at their disposal, do operators actually use them? “Operators fall into two camps,” says Adam Woods, product marketing specialist at Link-Belt, “those who are in complete compliance with the use of various modes, and those who just want full power all the time.”

Matt Hendry, product consultant with John Deere and Hitachi, suggests supervisors tell operators which mode to use for a particular job and then use telematics to confirm compliance.

In their new Discovery Series, Gradall took a different approach to the mode conundrum: they did away with modes. “Operators don’t read manuals,” says Mike Popovich, vice president of sales for Gradall, “and at some point, they’ll put the machine in ‘Grade’ mode and then complain about its lack of performance and cite the dreaded ‘drive-by-wire’ technology.” Popovich says Discovery Series machines have sophisticated performance algorithms that adapt to conditions without relying on modes.

Split on autonomous While not as numerous as mode options, there are several levels of machine autonomy and assist, and some models have no such features at all. At the lower end of this assistance are excavators with an indicator on the monitor. Operators dig and grade to plan using the indicator as a guide, but the actual digging and grading is still under the operator’s complete control.

A few machines have complete GNSS control, while others have semi-autonomous control. Semi-autonomous control is more common on other types of machines, especially dozers and graders, primarily because dozer blades and grader moldboards are easier for GNSS systems to understand and control. Even a 6-way PAT blade is simplistic compared to the complexities of planning for buckets on an excavator. The system has to have the teeth-to-bucket pin dimension, which changes every time the bucket is changed, and it must keep up with changes to the bucket’s position every time the bucket is curled, or the stick or boom is moved.

Not all OEMs are convinced that machine control technology is sufficiently advanced for use on excavators. “Technology is nowhere near where it needs to be, in terms of accuracy and reliability, for us to add it to our machines,” says Popovich.

Some OEMs, such as John Deere and Hitachi, leave the decision to the customer by providing optional pre-installed packages. These packages may include electrical and hydraulic attachment points for Topcon, Leica, or Trimble systems, which can be installed by the dealer or a third party. But that’s not as simple as it sounds, according to contractor Jack Bailey, Sr., president of JBR Construction and Consulting in Fredericksburg, Virginia. “You go to have a system installed and the installer says, ‘We’ll have to add this and this and this.’ It’s supposed to be plug-and-play, but it’s not.”

Lee Smith, crawler excavator product specialist with Doosan, says their machines have no autonomous function and there are no pre-install options available for aftermarket systems. “We have seen only limited customer demand for these systems,” he says.

Some OEMs are fully committed. Komatsu introduced their intelligent Machine Control on the PC210LCi in 2014 and now offers it on two additional models, the PC360LCi-11 and PC490LCi-11. The feature prevents over-excavating, and Komatsu recommends it be used any time the goal is to hit a target grade or elevation.

Operators aren’t always immediately comfortable with autonomous digging. The solution is to get them to use the system for a while. “Using the system will convert skeptics into believers,” says Jason Anetsberger, senior product manager for intelligent machine controls at Komatsu.

26 September 2016 | EquipmentWorld.com

Available on the 326F and other excavators, Cat Grade Control Depth and Slope combines digital design data and real-time bucket tip positioning with in-cab cut-and-fill guidance.

An upgrade to AccuGrade provides 3D control.

While Hitachi does not offer a factory grade reference option, several of their Dash-6 excavators, such as this ZX300LC-6, come with a pre-install package for Topcon, Trimble, or Leica that cuts installation time in half.

Komatsu describes their PC490LCi as “the largest 3D semi-automatic construction-sized excavator available today.”

Features of that system, such as Auto Grade Assist and Auto Stop Control, are displayed and managed through the 12.1-inch screen of this control box.

machine matters Big screens, big data Monitors are growing; 7- and 8-inch screens are becoming common. The 12.1-inch screen on the Komatsu Control Box takes first place in the screen size category. Monitors may be touch-screen, but some OEMs feel touch-screens aren’t suited for use in the damp and dirty world of construction, so they use buttons or other controls instead.

Most controls, from work modes to wiper speeds, are moving from switches on the console, to options on the monitor. The central lubrication system on Liebherr excavators, for example, is automated, but can be managed via the monitor.

Icons convey information efficiently, but Hendry says operators need to be familiar with those icons so that they know what action, if any, is required.

For example, an icon will appear when the emissions system is going through a regeneration cycle. The operator doesn’t have to do anything during regen, but should not shut down the machine until the regen process is completed.

Telematics have mixed acceptance among OEMs, just as they do among customers. Gradall offers no telematics. “Right now, telematics are almost entirely an OEM and rental feature, not an owner/operator feature,” says Popovich. But even if a customer isn’t using telematics, the comprehensive history provided by telematics enhances residual value. “It’s the Carfax of the construction industry,” says Corey Rogers, marketing manager at Hyundai.

and the relationship between the seat, consoles and controls can provide more than 100 adjustment options. This area, especially, is one in which OEMs can offer little guidance. In a world where everyone from data entry clerks to bicyclists have established ideal seating positions, often measured in fractions of an inch, many OEMs just instruct operators to adjust the seat to their preference. Juston Thompson, product specialist at Hyundai, starts off the conversation. “Set everything up wrong at first,” he instructs, “just to see what ‘wrong’ feels like.”

Woods says managing the shoulder, elbow and wrist is the key to comfort. “Ideally you want the elbows at 90-degree angles and the wrists straight.” But Woods acknowledges that comfort is highly individualized and can vary by application.

Hendry says that controls should be operated with the wrists and that the shoulders should not be involved. The key is to set the seat position in proper relation to the controls. “Even an inch makes a difference,” he says.

Other technologies contributing to operator comfort include improved sound systems with Bluetooth compatibility and mp3 inputs, high-capacity HVAC systems with an abundance of vents, increased cab volume and floor space, and additional in-cab storage. Cabs are pressurized and isolation-mounted to reduce dust, noise and vibration. None of these is cutting-edge tech, but taken together, they increase operator comfort and reduce fatigue.

Visibility Camera options range from none to one to many.

Some cameras show only behind the machine; some behind and on the right; some stitch together multiple views for a 360-degree bird’s-eye view, which is the big buzz right now.

Hyundai calls their 360-degree view All-Around View Monitoring (AAVM). They also offer Intelligent Moving Object Detection (IMOD), which responds to sound and motion within five meters of the system’s sensors.

Sound picked up by IMOD microphones is played through the cab monitor.

The Wide Angle View Enhancement System (WAVES), available on Link-Belt excavators, offers a 270-degree view. The rationale is that operators have an unobstructed view to the left of the machine and that the camera system need only provide visibility to the areas unseen from the operator’s seat. The monitor can display either the 270-degree view or individual images, two of which can be viewed simultaneously. Woods says the operator should choose the view or views based on conditions, such as whether the machine is working or being repositioned.

Because of the diversity of Gradall models, they offer a wide range of camera systems. Popovich’s recommendations are that operators know how to use their 30 September 2016 | EquipmentWorld.com

Gradall’s XL 4100 V excavator can be oriented to give the operator the best view of the work area, but can be repositioned from the upper structure cab to save time. A front-facing camera and in-cab display enhance safety during repositioning.

A Premium seat option adds air conditioning with activated charcoal and a fan, as well as weight-actuated electronic height adjustment. cameras, continue to use spotters as required, and set up the job site for optimal visibility.

Technology is creeping into lighting, as well. There are more lights – in some cases 10 or more – and options include halogen and LED elements. Liebherr has a feature called “Follow Me Home,” where lights can remain on after the operator leaves the cab to enhance safety in low-light conditions.

Beyond cameras and lights, visibility has been improved with flat glass replacing curved glass to reduce distortion, glass in place of polycarbonate to eliminate hazing and checking, and larger glass panels. Mike Salcedo at XCMG/ Intensus says when it comes to the size of glass panels, there’s a sweet spot between visibility and reduced risk of glass breakage, which affects such design considerations as how close glass panels are to the floor. This is especially important for rental machines, which comprise some 80 percent of XCMG’s sales.

The ultimate objective of all these efforts to improve visibility is to enhance what Kurt Moncini, senior product manager of tracked products with Komatsu, refers to as “situational awareness.”

Low-tech in a high-tech world Some OEMs provide lower-tech machines for customers who don’t need fully-featured models, such as the rental market.

While XCMG has Tier 4 Interim machines available, they use EPA’s Transition Program for Equipment Manufacturers (TPEM) exemptions to offer Tier 3 as their standard configuration.

Ryan Neal, product application specialist at Caterpillar, says Cat’s 313F L GC is aimed at customers who are especially mindful of owning and operating costs, and for whom increased production doesn’t significantly increase their revenue. The 70-horsepower engine doesn’t require DEF to meet emissions standards and the machine has a simple one-pump hydraulic system. (At 29,300 pounds, the 313F is a bit below the range we’re covering this month. It’s included as an example of a lower-cost, lowerspec’ed machine.)

Michael Watt, excavator product manager with LiuGong, says all LiuGong excavators are designed to be simple to service. “Entry-level technicians with basic hand tools can do the work. There’s no need for proprietary software or a laptop to enter LiuGong electronic controls.”

Making it work Back to the opening questions. Does all this technology benefit customers? And if so, how can customers learn to get the greatest possible benefit from it?

Contractor Bailey says it seems some features are created just because they’re possible. “If technology doesn’t increase production or communication, it’s just technology for the sake of technology,” he says. But technology adds cost. “To absorb these 8 and 10 percent price increases, I have to be 20 percent more productive,” he adds. “The technology may get me there, but you have to show me how.” Bailey says OEMs and dealers often fail at this. “JBR has embraced technology and information management, but we need better training. Most of what we’ve found out [about employing technical features], we’ve found on our own. There’s a real disconnect, and the responsibility for correcting this disconnect lies with dealers.”

At 22.49 metric tons, the JS220 features a 70/30 split front windshield, large laminated-glass roof, and low hood lines for enhanced visibility.

HOW I SELECT AND USE H HYDRAULIC HAMMERS Editor’s note: W e reader perspect welcome ives such as Elliot’s. If yo u’ve knowledge that gained yo to share with ou u want r readers, contact Tom Ja ck tjackson@rand son at allreilly.com.

ydraulic hammers, or breakers, are some of the most used, least understood machines in the heavy equipment world. They can make or break a job…and the bottom line.

It’s not hard to understand why: a hydraulic hammer can cost up to 20- to 40-percent more than the carrier it’s mounted on, and can require two to three times the maintenance and repairs over the course of its life. Additionally, contractors often have more questions about hammers than they do reliable answers.

Ask around Over the past 12 months, part of my job was to research options in the hydraulic breaker market for my employer. During my search I learned a lot about hammers, and hopefully this information will remove some of the mystery surrounding hydraulic breakers.

When I first started this project, I talked to several contractor friends to get their input on hammers. I found that most had purchased whatever their dealer offered, mainly due to the lack of reliable information. They all had a brand or two they liked, a few shared a

Products Allied Allied’s Rammer series mid- and large-range hammers are designed for carriers from 26,500 to 176,000 pounds and feature high-strength housings for durability. Slip-fit tool bushings allow for easy replacement, and a simplified attachment system speeds installation. The company’s VIDAT system uses vibration dampened tie rods that reduce operating costs, extend life, and minimize downtime. Top down lubrication is standard, and remote lubrication and air lines can be installed for underwater work.

Atlas Copco The energy recovery system on Atlas Copco’s 4.5 ton HB 4100 breaker uses the piston’s recoil to power the next blow, minimizing vibrations and hydraulic demand from the carrier. Sized to fit 40 to 70 ton carriers, the HB 4100’s AutoControl system automatically adjusts how hard the breaker hits based on the density of the material being broken.

brand they’d never own again, but most agreed their knowledge was limited and that they didn’t really know how their hammer stacked up against other products. I also turned to our own fleet data and looked at the repair costs vs. hours of use on the hammers we already owned.

If you Google ’hydraulic hammers’, you will find a myriad of companies and offerings. There are plenty of online forums with posts about the good, bad, and ugly of different brands. One contractor’s favorite was another one’s worst nightmare. It was easy to see why so many people just buy what their local dealer offers and hope for the best.

However, I also identified a couple of brands that merited additional research, added the best of our current manufacturers, and then finished off the list with a few recommendations from other contractors and sales reps. I took that list, put out requests to vendors and compiled as much information as I could find online. I looked at the purchase costs, warranties, support availability and any references they had.

Do a demo At the end of our search, we conducted a demo on a jobsite with the finalists. Equipment is a major investment; demos help ensure you’re maximizing the return on those dollars. Most manufacturers or dealers will be happy to let you run a machine for a day or two to ensure it performs to their claims and your expectations. With hammers and other attachments, I recommend performing a demo with the carrier you plan on using it with most often. Seeing it run on your tractor is the only way to ensure you get the performance you’re expecting.

The main criteria I used for my comparisons fall into a few separate categories.

36 September 2016 | EquipmentWorld.com

Size matters Not all 5,000 pound hammers are the same. But, since there aren’t established industry standards for hammer sizing, it’s pretty much left up to each manufacturer to size their products. One company’s 5,000-pound hammer could be the same size as another company’s 7,000-pound hammer. So, how do you compare apples to apples?

The best method I’ve found is by using the piston diameter or bit diameter. All things being equal, the piston size is going to determine how hard a hammer hits. A 5,000-pound hammer with a 4-inch diameter bit is unlikely to out-produce a 5,000-pound hammer with a 5.5-inch diameter bit. I also take into consideration the weight of the hammer, but the piston or bit diameter is the best indicator.

It’s critical to ensure that the hammer you select is the right size for your carrier. A hammer that is too small can be damaged by the weight of the carrier or excessive hydraulic flow. Having a hammer that is too big will result in weak or slow strikes, reducing productivity.

Go with the flow The next step is to check the flow requirements for each hammer and make sure it matches your carrier. Some hammers require more flow than others to operate correctly. Without sufficient flow, you’ll end up with a slow, unproductive hammer and a lot of overtime. Too much flow for a hammer will cause overheating in the hammer and the carrier, destroying seal kits in both and potentially ruining the hammer.

Keep in mind that even correctly sized carriers can overflow a hammer. Today’s construction market has a multitude of attachments, some requiring large amounts of flow or high pressure to operate. Carrier manufacturers have responded with new models that

Bobcat If it’s flatwork you’re demolishing, the Bobcat drop hammer attachment hits at 20 blows per minute and allows the compact loader operator three seconds between each blow to reposition the loader.

The move-hit-move operation quickly breaks up large concrete expanses. The attachment impacts with 3,600 foot-pounds of energy and weighs just 1,925 pounds.

Chicago Pneumatic With a service weight of 4,850 pounds, the Chicago Pneumatic RX 30 has an impact rate of 620 blows per minute at 5,500 foot-pounds.

It is sized for carriers from 25 to 40 metric tons. The RX series features a hybrid gas/oil technology, fewer moving parts for reduced maintenance, and noise and vibration dampening technology for quiet operation. A vented percussion chamber directs dust away from the tool holder, extending bushing life.

Caterpillar The new Cat H80E and H80Es Series hammers are designed for Caterpillar’s backhoe loaders and 307 and 308 excavators, as well as other brands of carriers. They deliver 1,000 foot-pounds of energy at 600 to 1,500 blows per minute. Compared to the D-Series, they feature a lighter operating weight and wider oil flow to improve fuel consumption. An auto shutoff system prevents blank fires.

have hydraulic systems capable of running these attachments, meaning the potential to overflow a hammer is significant. Before you put any attachment on a carrier, have the unit flow tested to make sure you have it set within the safe zone for that attachment. This is critical. Perfectly good hammers have been destroyed in a few short months by running them on carriers not properly flow tested for that unit. The cost of having a dealer or mechanic set the flow is a fraction of the cost of rebuilding or replacing a hammer.

See the future Everyone looks at the purchase price of a new piece of equipment. However, with hammers, I also recommend that you find out the cost of resealing and rebuilding them. One of the frequently overlooked aspects that surfaced while researching our current fleet was that some of the more competitively priced hammers actually had higher repair costs when it came to parts and labor.

Most hammers will have to be resealed periodically. Knowing the cost of the seal kit and the amount of labor required can prevent huge repair

bills in the future. Also, take a few minutes to ask the service manager how often they expect to reseal the hammer. I didn’t give much weight to that information, as it’s subjective and highly variable, but I did learn a lot about different hammers by asking that question.

in the initial purchase prices.

But the real selling point wasn’t the initial price or the cost of ownership, but rather the production of the hammer on the demo. Production pays the bills, but the research paid off when finding a vendor to meet all our needs at an affordable price.

Ask for references Most people will hesitate to ask for references, but it’s a valuable tool that can help you make a good buying decision on new products or vendors. Most dealerships have large enough footprints and customer bases that they can provide you with a non-competitive contractor/customer already using that product as a reference. That phone call could save you thousands of dollars, so step outside your comfort zone and pick up the phone.

Now that you own a hammer The final topic I want to touch on is hammer maintenance and care. There are no shortages of unfounded theories on this topic; plenty of conjecture, and a lot of myths and wives’ tales.

• Grease – You cannot over grease a hammer, but you can under grease one. Make sure you use high temperature grease that will hold up to the rigors of hammering.

• Storage – Ask the manufacturer the best way to store their hammer, as it depends on the design. Most can be stored laying on the ground, but make sure that you cover all ports to keep out rain and other contamination. If you store your hammer upright, make sure it’s in a holder that supports the housing so the weight is not on the bit.

• Dry firing – Make sure your

Add it up In the end, we based our buying decision on a comparison of the initial purchase price, warranty, cost of repairs, parts availability, references from current customers, and the final demo. Even with a multiple unit purchase, there was a sizable difference

With 30 percent fewer parts, they can be rebuilt in as little as one hour. A tool retention system enables quick change outs with only one screwdriver. A two-hour grease schedule and 1,000-hour service intervals reduce downtime and maintenance costs.

Indeco Sized for large quarry operations, the Indeco HP25000 enables operators to take on rock breaking operations that previously required explosives. Standing 10-foot, 10-inches tall, the breaker weighs 24,370 pounds and offers striking power in the 25,000 foot-pound class. It can accept chisels with diameters of more than 10 inches and fits on excavators from 130,000 to 303,000 pounds. Tapping into hydraulic flows of 110 to 137 gallons per minute at 2,600 psi, it can hit at 240 to 460 blows per minute.

JCB JCB has launched its Contractor Hammer Range, including the compact HM012T that weighs just 220.5 pounds, up to models suitable for 22-ton excavators. Accumulators inside the breakers protect the carrier machine from hydraulic pressure spikes. For hammers on equipment larger than 12.1 tons, auto-lube systems insure the attachment gets the correct dose of grease. Two-speed control valves on models above 9.9 tons allow the operator to customize tool speed and stroke length.

operators are firing the hammer with resistance on the bit. Hammers are designed for the piston to impact the bit. When the bit is not there to resist the piston’s downward motion, it bottoms out the piston and causes damage to the hammer.

• 5 to 10 on / 5 to 10 off – We’ve all seen operators firing a hammer for minutes at a time. This is not an effective practice, as it overheats the hydraulic oil, thinning it out and reducing performance. Constant firing also destroys seals and hoses due to the high heat. By running it for 5 to 10 seconds, then breaking for 5 to 10 seconds, you’ll have more power in each strike and less heat in the hammer and carrier. Overfiring also overheats the bit. If you see a bit that is mushrooming at the tip, it’s most likely due to the operator not resting the hammer.

• Setting the flow – I talked about this above as well, but having the flow set to the hammer’s specs is critical. Look at your manual for the maximum and minimum flow levels and pressures. Then have a mechanic or your dealer come and set the tractor to match the hammer.

• Don’t pry – Often, operators will drive a hammer in and then try and pry the material out using the bit as a pry bar. This not only destroys bits, it can also cause damage inside the hammer, resulting in major repairs. You can tell if an operator is prying by looking at the bits as they will break a few inches below the bottom of the hammer housing.

maintenance with the manufacturer before hammering beyond 45 degrees off vertical. Some hammers can be damaged by running them beyond that point.

• Don’t sharpen points – Some contractors try to extend the life of bits by having them re-sharpened. Keep in mind that whatever you’re seeing on the outside is happening inside your hammer as well. So, a flattened bit is also mushrooming inside your hammer, causing damage to the internal housing.

• Cheap bits are expensive – There are some high quality bits at affordable prices on the market, but do your research first. Poor quality metal bits are also being sold in the States, and can quickly damage a hammer by mushrooming inside the housing.

One thing I always discourage is buying used hammers – especially from an auction. This may seem like a huge potential savings, but it typically ends up costing more than a new hammer due to the high cost of parts and service. Also, remember that the oil in your hammer is going to cycle through your carrier, contaminating your tractor as well.

THREE VIEWS ON THE PAST, PRESENT, AND RAPIDLY EVOLVING FUTURE OF GPS IN HEAVY CONSTRUCTION Part 4 of a 4-part series

Illustratio

I

t’s hard to believe, but the use of GPS in heavy construction is now more than 15 years old.

Mike Momrow, survey manager for the Rifenburg Companies in Troy, New York, was present at its genesis, purchasing and fielding a GPS machine control system in 2000 from a company called Geologics.

“Unfortunately, they didn’t stick around very long,” Momrow says.

But today, Rifenburg has about 60 rovers in the field and 30 to 35 machines running GPS applications, depending on the mix of jobs.

“Rifenburg doesn’t use GPS, we run on GPS,” says Momrow. “We use it for everything – for grade control in dirt, concrete paving, asphalt paving, motor graders, excavators – you name it, we use it.” And they use both Topcon and Trimble products. “Different crews like different systems,” he says.

The company’s crews have also figured out how to use total stations

Technology is advancing to the point where almost everything you do on the site will be connected wirelessly.

in conjunction with GPS. Depending on the job, they may do the bulk earthmoving with a dozer and then set up a motor grader with a robotic total station to complete the finish grading.

Can’t afford not to Before GPS, every job had its own foreman, laborers and a survey crew, says Momrow. Today, one foreman can cover three or four dirt operations and the survey crews are almost non-existent. “That has enabled us to lower all of our bid prices, because we’re cutting as many as three to five people out of each job,” he says. “And the operators are no longer waiting for a grade check. They have real live grade checking, all the time…all day, every day.”

In addition to machine control in earthmoving, Rifenburg started using GPS technology for paving in 2004. By 2006, it was using GPS on its milling applications as well,

Momrow says, and it is still one of the few companies in the country to have finessed this application.

Most recently, the company has invested in the latest GPS technology – the “mast-less” machine control dozers that use inertial measurement units (IMUs) mounted to the body of the machine, rather than antennae on the blades. It has purchased a Caterpillar D5K running Topcon’s 3D-Max system, as well as several Komatsu D51i intelligent machine control dozers.

Momrow is bullish on the new, IMU-driven dozers, calling them the best grading dozers he’s seen. But, he cautions contractors to make sure they’re guaranteed good support in the field before purchasing these or any other technology systems.

The biggest challenge While power users like Momrow continue to push the abilities of every new system, one significant headwind remains.

EquipmentWorld.com | September 2016 45

GPS/GNSS 101 | continued GPS-guided asphalt milling is one of the applications construction technology power users are beginning to master.

“We just don’t have enough machine control or survey guys who can take the technology and run with it,” Momrow says. “We’re trying, but we can’t find them. We need guys with real life, everyday experience out in the field. There is not a college in the United States that teaches machine control technology. You still have to learn that on the job.”

The company uses downtime in the winter to run two and three day training classes. If they hire somebody new in the construction season, they’ll spend a half day or so getting them familiar with the technology, and then come back for follow up and additional training a few weeks later.

Challenges aside, there is no excuse for not getting into GPS technology, Momrow says. “My advice: Don’t wait. If you do, every day you’re getting further behind.”

The future is connected One of the big trends on the horizon for GPS in construction is what 46 September 2016 | EquipmentWorld.com

Ed Shappell, director of technology services and solutions for Trimble civil division, calls BYOD, or “bring your own device.”

“In the future, you won’t need to buy a separate device other than your smart phone or tablet to work with your GPS,” Shappell says.

“That becomes your GPS position device, and you will be able to connect that to any machine you are working with and use it as the interface to everything else.”

And while you’re working with that device, you can communicate with a whole lot more than just the machine or the GPS satellites.

“Innovators today are starting to consolidate data from all assets, whereas in the past it was just the big machines,” says Shappell.

“We see customers today who are collecting GPS data from even their non-powered assets, such as machine attachments.” Tagging smaller equipment with GPSbased telematics and giving all the employees the ability to find it on a single dashboard can prove

to be a big time saver on large or complex jobsites.

Safety enhanced Contractors are also starting to use GPS, geofencing, and other machine tracking applications to enhance the safety of their crews as well. “They can set up geofences for environmentally sensitive areas and potentially dangerous or hazardous areas,” says Shappell. “That increases the amount of visibility that a foreman has into where the workers are and where the machines are.”

And since all of this GPS generated information can be logged and recorded, supervisors and safety personnel can analyze it after the fact. “When you have both worker and machine data, you can start looking at breadcrumb trails,” says Shappell. If you start noticing a path where your machines and workers intersect frequently, you may decide to redesign the jobsite, cordon off certain areas from foot traffic or make other changes.

GPS/GNSS 101 | continued M to M communication The mining industry is already using what’s known as ‘M to M’, or machine-to-machine communications, in autonomous mining trucks.

Using GPS signals, each machine knows where the other machines are and will stop if a collision is eminent. Mine operators are also putting up geofences around grinders and stockpiles, anything that might pose a danger to the trucks, other machines or workers.

Machine autonomy is progressing slower in construction, primarily because construction sites have more workers, complexity and moving parts. In most off road applications, construction machines are set up to report their GPS location intermittently, every few minutes or in longer intervals. To get the full benefit of these safety features, the GPS tracking will have to be done in real time, Shappell says.

The emergence of the autonomous car will help drive a lot of this technology. Shappell envisions a scenario where autonomous cars can be networked into a grid that’s also populated by the contractor’s haul trucks. If the algorithm ‘sees’ that dump trucks are in route to a site, it can estimate traffic delays before they happen. It can then automatically reroute the autonomous cars while also simultaneously alerting the cars with drivers. “If a contractor can provide that kind of service for a DOT, that’s a huge advantage,” says Shappell. “That makes the DOT happy because it makes the public happy.”

BIM brings new opportunities A technology more familiar to building contractors, BIM (or Building Information Modeling), is also starting to migrate into the technology portfolios of earthmoving, sitework and civil engineering contractors. BIM is a process involving the generation and management of digital representations of built struc48 September 2016 | EquipmentWorld.com

tures and utilities.

There are a lot advantages to looking at 3D models in the civil world, says Shappell. Contractors who use their GPS mapping capabilities to record the position of utilities and other structures on something like a highway project can turn this BIM data into dollars.

“In the past, mapping was done post-construction, and that’s a lot more expensive and harder to do,” Shappell says. “A contractor who captures accurate GPS information that’s tied to a 3D model of the infrastructure can hand it off to the customer or use it post construction for maintenance and operations.”

and can’t pull in your trench box, you’re going to have to go back and hammer out another 6 inches of rock all the way up,” says Lodge. That adds substantial costs, long delays and wear and tear on the machines. But, if you over-excavate a foot or so to be on the safe side, you’re also spending additional money.

Initially there were concerns about the durability of the sensors on the excavator in hammering applications, says Lodge. But sensors today are incredibly rugged, and hold up in difficult environments.

And even if a $1,000 sensor fails after six months, the productivity gains and cost savings in these applications would pay for it in a day or two. “The superintendent on this job says he wouldn’t do the job again without GPS,” Lodge says.

The big solar fields being built in the West require dozens of acres of solar panels all mounted on thousands of precisely positioned vertical posts set in holes created by rock drills, says Lodge. Rather than 50 September 2016 | EquipmentWorld.com

have a surveyor pound a stake for every hole, the drillers just create a digital GPS plan for the site and plug the information into a GPSguided rock drill. The operator positions the tip of the drill over the bullseye on the in-cab screen, drills to the depth needed, and moves over to the next bullseye. Repeat, ad infinitum, all day long.

Excavator applications of GPS, both 2D and 3D, are also gaining new converts. Most excavator digging goes to a specific depth and slope. “So why not measure it with your GPS, especially when you don’t need a surveyor or grade checker to do it,” Murray says. In addition to removing only the dirt that needs to be moved, GPS excavation eliminates the need to fill in and recompact low spots that were over excavated. Footings, trenches, and other precise grades and profiles can be cut with little need for finish or fill work.

Lodge also predicts that drones, or UAVs (unmanned aerial vehicles), will play a big role in the

construction site of the future. “I think in the next three to five years there won’t be a single mid- to large-size contractor who is not using UAVs, whether they use a service or their own UAVs,” he says. Tremendous progress has been made in harmonizing the kind of data drones collect with the kind of data contractors need to populate their software systems, and that trend will only continue to move forward, he says.

What forward thinking contractors are realizing, says Lodge, is that there are no fixed limits to what they can do with GPS. “In companies where the owners are empowering the employees to think outside the box, you start to see these new ideas coming from the operators, grade checkers and foremen,” he says. “They have a different mindset and they’re not stuck thinking they have to do things the way they’ve always been done. There are applications out there that people haven’t even started thinking about yet.”

Deadly driveshaft

ower take-off devices on trucks do a great many things, but like any rotating mechanical device, they need to be respected.

Case in point: In the fall of 2013, a dump truck driver pulled into a jobsite with the intent of dropping off a load of gravel. But, when he attempted to raise the dump box, nothing happened. The driver got out of the cab, and with the truck still running, lifted up the hood to inspect the engine bay.

Having found no solution to the problem in the engine area, the driver then laid down on the ground and crawled under the truck to see what the problem was. While the driver was prone under the truck, his shirt caught in the unshielded PTO driveshaft, which was still spinning,

Date of safety talk: Attending:

slamming his neck and head up against the driveline and choking him to death.

A short time later, the subcontractor he worked for noticed that the truck was not running and the driver was lying motionless under the truck. When the subcontractor saw the driver’s injuries, he called 911. Emergency responders cut the driver’s clothing free from the driveshaft and pulled him from under the truck. He was pronounced dead on arrival; cause of death: asphyxiation.

How this could have been prevented • Truck drivers should be trained on the dangers associated with PTOs and driveshafts.

• Prior to any work process, drivers and other personnel should

Leader:

ensure that the PTO is disengaged and the truck engine is shut off.

• Dump truck drivers should perform daily, pre-trip inspections, including raising and lowering the dump box.

• Never wear loose clothing when working around driveshafts or other rotating mechanical components.

• If not so equipped from the factory, trucks with exposed PTOs should be retrofitted with shields, and gearboxes should be relocated to more accessible locations.

• Always consult with a competent mechanic when attempting to investigate or fix mechanical problems.

Eje mortal

L

os dispositivos de toma de fuerza de los camiones cumplen muchas funciones pero, como a cualquier dispositivo mecánico giratorio, hay que tratarlo con respeto.

Un ejemplo a mano: en el otoño de 2013, el conductor de un camión de volteo ingresó a un área de trabajo con la intención de descargar una camionada de grava.

Pero, cuando intentó levantar la caja del volquete, no pasó nada. El conductor salió de la cabina y, con el camión aún encendido, levantó la cubierta del motor para inspeccionar el interior.

Sin encontrar la solución al problema en el área del motor, el conductor se acostó sobre el suelo y se arrastró debajo del camión para ver cuál era el problema. Estando debajo del camión, la camisa del conductor quedó enganchada en el eje de transmisión de toma de fuerza que estaba al descubierto y que seguía girando, jaloneando para arriba su cuello y su cabeza, hacia la línea de transmisión, ahogándolo hasta causar su muerte.

Poco después, el subcontratista para el que trabajaba notó que el camión no estaba funcionando y que el conductor yacía inmóvil debajo del camión. Cuando el contratista vio las heridas del conductor llamó al 911. El personal de emergencia le cortó sus ropas para separarlas del eje de transmisión y lo extrajeron de debajo del camión. Fue pronunciado muerto al llegar; causa de muerte: asfixia.

Fecha de la charla de seguridad: Asistentes: 54 September 2016 | EquipmentWorld.com

Líder:

Cómo pudo haberse prevenido esto • Se debe capacitar a los conductores de camión en los peligros asociados con las tomas de fuerza y los ejes de transmisión.

• Antes de cualquier trabajo, los conductores y cualquier otro personal deben asegurarse de que la toma de fuerza está desenganchada y que el motor del camión está apagado.

• Los conductores de camiones de volteo deben realizar inspecciones diarias, previas a cada viaje, que incluyan levantar y bajar la caja del volquete.

• Nunca utilice ropas sueltas cuando trabaje en torno a los ejes de transmisión u otros componentes mecánicos giratorios.

• Si no vienen equipados de fábrica de esta manera, los camiones con las tomas de fuerza al descubierto deberían ser modificados con cubiertas y las cajas de controles deberían ser reubicadas en lugares más accesibles.

• Consulte siempre con un mecánico competente cuando intente investigar o componer problemas mecánicos.

oncrete mixtures for paving present unique challenges, primarily because most pavement designs require the mix to stand up, particularly at the edges and back of the paver.

Thus, it’s critical for the mix to have the correct proportions of the three main components: cement, water and aggregate.

The aggregate is the biggest part of a concrete mixture’s volume and weight. It’s also the cheapest portion of the mixture, and the least uniform component.

While cement and water are critical and need to be monitored, the aggregate poses the EquipmentWorld.com | September 2016 57

biggest challenge for concrete pavement contractors, according to Leif Wathne, executive vice president of the American Concrete Pavement Association.

“A lot of the issues with plant operation is aggregate handling, so the loader operator becomes a key feature of a concrete mix operation,” he says. “If your loader operator knows what he’s doing, you’re going to be much more likely to have a consistent mix that performs the way it’s designed, and is proportioned properly.”

That also factors into making sure contaminants don’t get into the aggregate and making sure the aggregates are not segregated, which falls under stockpile management.

Moisture content is a big issue in this process, Wathne says. “A lot of plants will put

Stockpile management

Managing aggregate is a top management concern in concrete production, as it is the most unpredictable component of a mix. Here are a few stockpile management tips.

• Pile the material in lifts.

• Complete each lift before beginning the next.

• Do not dump material over the edges of a stockpile.

• Minimize free-fall heights of aggregates to avoid segregation.

• Only stockpile as much material as is practical.

• Minimize crushing of the aggregate by the loader.

• Manage the stockpile carefully to obtain close to saturated surface dry condition. For example, thoroughly wet the aggregate, then let it stand an hour before batching.

• Monitor the moisture content of the aggregate using probes in the stockpile.

sprinklers on, but how they manage that is going to control whether that moisture is super wet on top. Just because they put sprinklers on top doesn’t mean it’s going to be at the right moisture content.”

But well-graded aggregate is perhaps the top issue, he says, stressing the effect of this factor on performance. (In fact, the asphalt industry has also been focused on this, because the consequences of poor aggregate gradation in asphalt pavement are more obvious and can cause immediate problems.)

“In concrete, it may not be inherently obvious what the performance issues are. Even placement issues are associated with poor aggregate gradation,” Wathne 1says.

A growing concrete segment: Roller-compacted concrete

O

nce considered a rough and dusty product, roller-compacted concrete (RCC) is gaining traction in the concrete pavement world. While the best applications for RCC are still considered to be intermodal settings or warehouse distribution facilities – areas that need a surface to withstand heavy weight – it is beginning to take hold in areas once shunned.

Robert Smith Incorporated in Chattanooga, Tennessee, specializes in RCC, and in addition to completing projects for Volkswagen’s facility near its home offices, it has also completed work for the Virginia Department of Transportation, placing RCC for shoulders and ramps.

“Departments of transportation (DOTs) are starting to use it

in adoption is improper placement.

“To this day, some of the biggest roadblocks and concerns with RCC, even though they are decreasing each year, are older projects that might not have been placed correctly,” Smith says. Because there was a big learning curve with the mix in the early days of its usage, that

perception of rough and dusty lingers.

“It used to be kind of rough because it had too much rock in it and not enough sand,” Smith explains. “We’ve adjusted that now. The dusty perception came from leaving cement powder on the pavement after cutting the joints. We now go back and clean those joints.”

Tougher Than Everything Montabert breakers sense the hardness of material, adapting their power and strike frequency to deliver just the right amount of energy. You get the best possible performance every time, without all the wear and tear.

“Some DOTs are even starting to use it as base materials under their asphalt, because that asphalt is just being milled and overlayed years later. They’ll never take the base up.”

Like other concrete mixtures, RCC’s qualities depend on the ratios of cement, water, and aggregate. Smith points out that the strength of this form of concrete is a result of finetuning that ratio.

“Because the cementitious content is higher than conventional concrete, and the water is lower, you get some of your strength and your density there,” he says. That strength? RCC mix breaks at an average of 5,500 psi at 28 days.

“That’s the main advantage is that it’s a stronger concrete than conventional concrete.”

Plants need to have an assortment of aggregate gradations, including coarse, intermediate, and fine. “I think getting well-graded aggregates is the most cost effective way for a concrete paver to consistently deliver and place high quality concrete pavement,” Wathne says.

Admixtures The concrete paving industry has been criticized for its seemingly increasing reliance on performance-enhancing admixtures.

“Along with these various admixtures, when we also use supplementary cementitious materials like fly ashes or slags, sometimes incompatibilities can develop that cause the concrete to react in unexpected ways,” he says. And some admixtures are sensitive to extreme ambient temperatures or too-wet aggregate.

“You then have outcomes you would never anticipate,” Wathne says. “It’s just a more complicated system. In the past, we didn’t have these tools available to us, so we ended up with mixtures that performed fine, but they were probably not optimized.”

Performance troubleshooting When a pavement isn’t performing as it should, a contractor may first feel he should contact the paver manufacturer.

The first thing the manufacturer will do is ask about the mix qualities.

In addition to the aggregate gradation, contractors must also look at the design of the mix and the proportioning. The design establishes the concrete’s strength, intended purpose, and environment.

This means contractors must

scrutinize what they are designing, the proportions of the mix, and other specifications to determine if they can expect it to perform properly.

“A lot of it has to do with uniformity as well,” Wathne says.

“You’re paving day in day out

and it’s a tough environment out there because the weather and material changes.” Contractors have to constantly adjust for all these variables in their paving operation so that a uniform, smooth product comes out of the paver every day.

urricane Katrina is simply called “The Storm” in New Orleans, and that’s certainly a description of what it created in Tina Dieudonne’s life. Her small, tourist-related businesses took a hit in the storm’s aftermath, and she realized she needed to look for another opportunity. She found it in the massive rebuilding that consumed the city after the hurricane.

Taking the road and bridge contractor licensing test in 2005 after she formed Dieudonne Enterprises (DE), Tina got her Disadvantaged Business Certification in 2006. She now holds three state licenses, and concentrates,

as she puts it, on “making sure the company makes money.”

After starting the company in her home, Tina eventually located it at its present location in a suburban industrial park in 2011. DE, which started out doing curb and gutter work and Tina Dieudonne, Dieudonne Enterprises

small asphalt jobs, today has added street construction, subsurface drainage and pipework to its resume. The company now has revenues of $8 to $10 million and employs 75 people.

“Miss Tina” Chad Albert, DE’s project manager, who refers to his boss as “Miss Tina,” explains the company culture this way: “We have fun. We have a wellrounded group of employees and we’ve grown big time in the past five years. We’re always trying to expand.”

Tina’s husband. Perrin serves as operations manager and estimator, and Anthony is the firm’s field project manager and safety coordinator, in addition to being its equipment manager.

“Communication is important,” Tina says. “It’s not just one of us, it’s all of us. I’ve brought together guys I can trust,” including superintendents Cesar Fonseca and Chris Cowie. DE has six full crews, plus some specialty teams for saw cutting and joint sealing. “My guys don’t say, ‘that’s not my job,’” Tina elaborates. “If they are operators, they will come off the machine and pick up a shovel. I can’t praise the people in my company enough.” Her crews usually work four 10-hour days each week.

Stepping stone jobs Tina is appreciative of the contractors who gave her a chance to sub for them at the beginning, including Boh Brothers and Gibbs Construction.

“They gave us stepping stone jobs 70 September 2016 | EquipmentWorld.com

and were extremely helpful in their payment structure,” she says.

“They’re a good example of how a DBE can start up small and then do more and more work,” says Darren Grille, an estimator at Barber Bros.

Construction. “Tina’s a good mentor on how to build a business without taking on more than you can handle.”

The company’s fleet includes eight backhoes, along with compact excavators, compact track loaders and rollers. DE now has an in-house mechanic, and regularly trains operators by working with their local dealer.

“They don’t want anyone to have the excuse that they didn’t know about something,” says Mark McElroy with Louisiana Cat. “And they stay on top of preventive maintenance. There’s no duct tape on their jobsites.”

A big little company “I like being a big little company,” Tina says. “I would advise contrac-

tors just starting out not to grow so fast. The market changes and the competition is crazy. I’d rather use a sub than hire and then have to fire someone.”

“They have the ability to grow young talent,” McElroy says. “They are small enough to still be personable, but large enough to expand.

And because they are such a tightknit group, they excel at solving problems.”

“Tina is an extremely capable construction professional,” says Lawrence C. Gibbs, CEO of Gibbs Construction in Harahan, Louisiana.

“She has consistently demonstrated a high level of integrity and ability to complete a wide variety of demanding construction projects on time and in budget.”

DE has an excellent .78 experience mod rate; a result due in part to adopting a “Thinking + Safety = Zero Accidents” program, headed up by Anthony. “They are going to

do it right, no matter what,” says Joe O’Conner with their insurance firm, Trimble-Batjer Insurance. “She’s doing everything that we as risk managers want; the company is hitting it on all cylinders.”

A good life Tina says, simply: “We’ve done well, so we want our people to do well.

We want them to have a good life.”

The rewards of this attitude became evident one Christmas when an employee called her just to let her know that he was spending his first Christmas as the proud owner of a home … and as the very first homeowner in his family.

As for her plans for the future, Tina appreciates the steady growth DE has experienced to date. “You have to get good at doing a particular job before you go on,” she says.

“If you’re not good at what’s behind you, then it’s going to be hard to grow.”

STRINGLESS 3D PAVING FOR ASPHALT

3D machine control provides the highest accuracy and smoothness levels possible for asphalt pavement – no strings attached.

S

tringless paving isn’t just for concrete contractors.

The asphalt guys are in on it as well, but with a few slight twists on the methods used.

As with concrete paving, stringless asphalt paving offers the benefit of eliminating the costly step of bringing in a survey crew to set up the stringline. Eliminating that step also removes the physical obstacles of the string and posts that get in the way of the paving crews

Caterpillar equipment paving in echelon on a curve while using Trimble’s stringless 3D system for guidance. 3D machine control is designed to handle curves such as this without difficulty. and the workers running ancillary equipment.

But when we talk about stringless paving in asphalt, the conversation turns to 3D paving, which involves not just the 3D positioning systems, but also 3D machine control.

3D vs. 2D In 2D paving, the action is about controlling grade. In 3D paving, it may include steering as well as automatic screed width control. The system works with a known 3D

model, which specifies what grade and slope should be at a given point. In 2D, it’s more about setting up and paving away.

Systems for 2D paving consist of a single display, sonic sensor, contact sensor or sonic averaging beam. In 3D paving, the same components are there, but the 3D system talks to the 2D system so they work in conjunction.

“When you’re talking about 3D paving, people generally don’t understand what’s all involved,” says EquipmentWorld.com | September 2016 73

highway contractor Nars Laikram, manager of commercial support and development for Vögele. He says 3D in this context is comprised of two factors: 3D job files and 3D paving. “When we say three dimensions, we are referring to depth, width, and direction.

That’s the 3D. In that case, you have a job file that tells you at the x and y location, what the depth should be, and what the width should be.”

Because of this, the most important factor in 3D paving is the model that is transferred into the machine control system. This model includes a proper survey, with the topography of existing conditions carefully compiled. Any errors in creating the 3D model will lead to errors on the job, as they will be replicated at the time of paving. In other words, the old adage of “garbage in, garbage out” applies doubly here. The site control must be maintained, as contractors can’t expect the paver to pave accurately if the site control is off in any way.

“3D systems communicate with a network of base stations that provide precise positioning data so the machines can work off a virtual design,” says Jon Anderson, global sales consultant at Caterpillar Paving. “The machines always have to maintain a line-of-sight to two base stations in order to precisely fix their position. Some urban environments can interfere with this, as can rural locations with heavy tree or brush cover. Usually, proper planning can ensure that the base station locations will not be subject to interference.”

In asphalt paving, you don’t necessarily need 3D control to drive the paver. You can get by with 2D machine control and just referencing off of sonics, especially with an averaging beam, and still get relatively smooth results, says Kevin Garcia, paving segment manager for Trimble. This is especially pertinent 74 September 2016 | EquipmentWorld.com

Scotty’s Contracting & Stone used Trimble’s 3D system when paving the National Corvette Museum Motorsports Park to meet the exacting specifications for smoothness required.

hen it comes to smoothness, perhaps nowhere is there more exacting needs than on a racetrack.

Scotty’s Contracting & Stone of Bowling Green, Kentucky, used 3D paving technology in the site prep and paving for the National Corvette Museum Motorsports Park, also located in Bowling Green. The facility is a test track for Corvettes.

Specifications required no more than 1/8 inch of deviation around the entire track length, as well as a smooth joint in the center. Scotty’s started with Caterpillar’s 3D AccuGrade on their dozers to get the grading down to 100ths of a foot accuracy, followed by 3D paving to within 1,000ths of a foot accuracy.

Joint matching the pavers used in echelon, Scotty’s used Caterpillar AP1055D and AP1055E pavers working off of Trimble’s system to fine-tune the slope.

“We never would have finished on time without it,” says Chris Higgins, engineering manager for Scotty’s. “The biggest benefit of 3D paving is it precisely and accurately achieves the design, giving us the smoothest, most consistent surface possible.”

highway contractor on projects where there’s no elevation specification, the top objective is ride smoothness, and material management isn’t a major concern.

“If you don’t mind being a little bit high or a little bit low in certain areas, you can get by,” he says.

Contractor benefits Where 3D paving excels and provides its biggest benefit is in accuracy, providing exact levels of smoothness and material management. The latter seems antithetical to what Garcia says about “getting by” with 2D paving.

“There are an increasing number of contractors who pride themselves on quality of work,” he says. “We see that list grow all the time, and machine control is a way for them to differentiate themselves at the bid table. With 3D machine control, you’re going to ensure that you hit minimum thickness of pavement without going over, which essentially is your yield. So, if you’re at the bid table, you can be very accurate with your tonnage, and therefore get your bid down. You are not having to put in as much fluff or overrun.”

While there are always early adopters for new technologies, Anderson says in most cases, contractors are using 3D systems to meet a specific challenge, such as exacting elevation or smoothness specifications, complex designs, or controlling material volumes. “It is still a bit of a specialty application – 2D paving is more than adequate for the vast majority of work,” he says. “A lot of work is still paid by the ton.”

Contractors may also add 3D paving to their stable of services to offer value-added change orders, Garcia says.

It’s becoming more popular for contractors to submit a value-added change order after submitting a traditional bid, he says. Contrac76 September 2016 | EquipmentWorld.com

tors can then go back and detail how many tons – and dollars – can be saved using 3D controls.

While there will be added costs using this approach, contractors can make it up in overall savings for the project. If, for example, the 3D machine control costs $50,000, but the contractor can save $250,000 on a project, then everyone wins, Garcia says.

Non-adopters While 3D paving offers improvements in quality and time savings, contractors can balk at using it.

“There’s a fear of giving up that manual control and trusting that the automated machine control guidance is doing what it’s supposed to do,” Garcia says.

Cost can be a factor. There’s the additional cost of total stations,

receivers, and perhaps fan lasers, all of which can cause contractors to balk. But in reality, Garcia says, the ROI on machine control systems is so quick that cost isn’t nearly the hurdle it used to be. “It’s more about the skill set of the crews in the field,” he says.

And contractors who do dirt work – where stringless controls have been proven performers – may have a leg up on paving-only contractors, since their crews already have that skill set.

“If a company also does earthwork, they may already have the infrastructure with their grade control systems on dirt moving equipment and the expertise to use it,” Anderson says.

Laikram posits one of the biggest challenges in the paving industry is the low number of contractors who understand the 3D side of things because they aren’t involved

in the dirt work. “On the dirt side, however, you have contractors who have specialists employed,” he says.

“Most asphalt contractors don’t do the dirt work themselves.”

Laikram sees this on the jobs he visits. In one instance, an asphalt paver subcontracted the stringline work. “That stringline probably cost them $50,000 to $75,000,” he says.

“If they had had a 3D system, they could have plugged all of that into the 3D system and controlled the machine right off it.”

Moving forward Increased adoption of 3D for paving contractors depends on strengthening specification requirements – some of which may even mandate 3D machine controls.

“We’re starting to hear states consider making machine control mandatory,” Garcia notes.

“When that happens, I think we’ll

see a lot of contractors adopt it.

There are contractors who have embraced this technology wholeheartedly and use it extensively in their crews, but they are still the minority.”

Anderson says a contractor might see 3D paving as an opportunity to specialize in more challenging work and to be one of only a few who can offer the option as a competitive advantage.

“There are considerable differences compared to standard 2D paving in terms of workflow, expertise, training and infrastructure,” he says. “But when the tolerances are tight, these systems are reliable and worth the investment.”

More contractors are adopting 3D machine control, Garcia says, adding: “To remain competitive at the bid table, and to ultimately put down the highest quality surface, they need machine control.”

The Cummins X15 Efficiency Series (left) and the X15 Performance Series (right) highlight Cummins’ 2017 engine lineup.

Cummins unveils X15, X12 engines, rebrands heavy-duty lineup

C

ummins has pulled the curtain back on its next-generation engine family; the 15-liter X15 (available in two configurations) and the 12-liter X12 heavy-duty diesel engines. Both engines build off the legacy of Cummins’ ISX platform and offer a variety of design and performance improvements depending on the model.

Cummins also said the new engines are ready to exceed the U.S. Environmental Protection Agency’s 2017 greenhouse gas and fuel efficiency standards.

Looming regulations aside, the engine launch is perfect timing for Cummins – a company whose dominant grip on market share has slipped in recent years

as proprietary, integrated enginetransmission packages from truck OEMs have taken a bite out of the engine maker’s business. Cummins answered with its own optimized platform, partnering with Eaton in 2013 to launch the SmartAdvantage powertrain package.

With its new X series platform, Cummins introduces its future heavy duty engine lineup aimed at owners who prefer red engines under their hoods, and attempts to woo back those who went the OEM route in their last purchase cycle.

Lean or mean While the ISX platform has only one 15-liter starting option, the X series offers two: The fuel-sipping X15

Efficiency Series geared toward linehaul and regional markets, and the X15 Performance Series, built specifically for heavy-haul, vocational and other demanding applications.

Cummins made several hardware changes to improve performance on the X15 Performance engine, including a high-flow EGR cooler, and piston cooling nozzles and exhaust valves to improve reliability. The X15 Performance Series boasts from 485 to 605 horsepower, torque ratings up to 2,050 pound-feet, and as much as 600 braking horsepower.

“We have increased braking power through the operating speed of the engine, from 1,300 to 1,700 rpm, where you need it the most,” said Jim Fier, Cummins’ vice president of engineering. “No matter how difficult the job, drivers will have the confidence that they’ll be able to get up the mountain and back down with no worries.”

The X15 Efficiency Series ranges from 400 to 500 horsepower and from 1,450 to 1,850 pound-feet of torque, with 400 braking horsepower at 1,300 rpm. In addition, Cummins has added predictive cruise control to its ADEPT suite of connected vehicle technology (see sidebar).

X15 Efficiency “Many have wondered about the role of the big-bore, heavy-duty engines in the North American market as compared to more recent medium-bore introductions, begging the question whether we’ll follow what’s happening in Europe,” says Lori Thompson, Cummins’ vice president of marketing. “With the benefit of several years of market experience, we can answer that question: the big-bore engine is here to stay.”

Cummins first announced its single module aftertreatment system concept in 2015, and it is now production-ready with the X series, combining VOC, DPF, and SCR into a single canister – and saving up to EquipmentWorld.com | September 2016 81

heavy trucks 60 percent more space while simultaneously reducing weight by 40 percent compared to the company’s previous aftertreatment system. In addition, the single module aftertreatment system allows the DPF cleaning interval to be extended to between 600,000 and 800,000 miles.

Cummins also announced its OilGuard oil analysis program, which offers customers the opportunity to extend oil drain intervals as far as 80,000 miles.

Light might The X12 Series engine ratings range from 350 to 475 horsepower and between 1,250 and 1,700 pound-feet of torque. It also sports Cummins’ best power-to-weight ratio at 2,050 pounds, 150 pounds lighter than the next closest competitive engine,

| continued according to Cummins.

Material has been removed from the block where possible, including the flywheel, adding structural support “ribs” to add strength and rigidity.

“This engine was designed from the ground up to remove as much weight as we could while retaining superior dependability,” said Fier.

The X12 will share several components with the X15, including the Cummins Holset VGT Turbo, XPI fuel system, engine control module, and the single module aftertreatment system.

After years of development and 9 million miles of testing, Cummins will begin limited production of the X15 late this year; full production will begin in January 2017. Customers wanting the X12 will have to wait until 2018.

Predictive cruise, OTA updates

C

ummins has also introduced a new package of engine connectivity options that give contractors the ability to update their trucks’ engines over the air (OTA), with either an updated calibration from Cummins or specialized tunes for improving fuel economy or application changes.

The company also announced an updated GPSbased predictive cruise control that gives its engines the ability to read road maps up to two miles ahead via GPS connectivity. The cruise system then uses that data to optimize acceleration and coasting for the best possible fuel economy.

The updated connectivity package includes the Connected Calibrations system and Connected Tuning, both of which join the already existing Connected Diagnostics unveiled in March 2015.

The two additions to Cummins’ Connected system will be available for both of their new 15-liter engines.

Cummins says the Connected Calibrations system allows the company to push out engine control module updates to its engines without the downtime associated with being taken to the shop. The Connected Tuning system, meanwhile, gives owners the ability to send new engine tunes to their X15 engines to more finely tune the engine’s ECM and performance to specific fleet applications.

T Deere partners with HCSS to deliver mixedfleet telematics data

J

ohn Deere has announced that it is partnering with HCSS, maker of Heavy Bid and other construction software products, to enhance the capabilities of Deere’s WorkSight telematics machine reporting system.

Most contractors know HCSS from their popular back-office software systems, but in recent months, the company has made substantial inroads into the telematics business.

This spring, the company debuted their Telematics Integration Services, which automatically pulls in machine data from multiple brands of machines in a mixed fleet environment, and enables you to see all of your telematics reporting without having to go to multiple OEM websites.

The Deere partnership with HCSS will integrate JDLink data into HCSS OEM Link, allowing customers to see Deere equipment alongside that of other brands in one location “Our partnership with HCSS empowers customers to leverage the existing telematics connection on

their John Deere equipment and see their JDLink machine data in the powerful HCSS tool suite in conjunction with other telematics brands,” said Liz Quinn, product marketing manager at John Deere WorkSight.

“In addition, customers will be able to easily link from the HCSS application to the MyJohnDeere.com environment when they need to order parts, manuals or have a closer look at a John Deere machine in the JDLink Dashboard.”

According to Deere, the partnership is an outgrowth of the work done by the Association of Equipment Management Professionals (AEMP), which has been working for several years to create a single, universal telematics reporting standard for heavy equipment and trucks.

Deere selected HCSS based on the company’s compatibility with its WorkSight technology. HCSS has also been working as an alpha tester of JDLink’s Machine Data API (AEMP 2.0) scheduled to be launched as an ISO spec later this year.

he company 3D Laser Mapping has launched a new multi-platform mapping system called Robin, which can scan and map terrain when worn by the operator while walking, or when attached to a moving vehicle, drone or helicopter.

Unlike most mapping systems, Robin can capture data from paths, forest trails, and coastlines that are only accessible on foot.

Included in the system is a 12-megapixel camera for driving applications and an 18-megapixel camera for walking and flying.

Two GNSS antennas pull in GPS satellite positioning data while a GIS-grade inertial measurement unit (IMU) orients the system to the site. The survey-grade system offers vertical accuracy as fine as 1 to 2 centimeters.

The laser scanner has a maximum range of up to 920 meters, with a relative accuracy of 5 millimeters. Two additional options are available: A Robin-Wings long range laser scanner (optimized for airborne operations) can scan up to 1,350 meters with 10 millimeter accuracy, while the Robin-Precision setup can reach out to 350 meters with 3 millimeter accuracy.

The walk/drive unit weighs 22 pounds and the flying unit weights 13.2 pounds.

Emmanuel de Maistre, CEO and founder of Red Bird, in his presentation, Attack of the Drones: How Unmanned Aerial Systems Are Impacting Your Jobsite, will talk about how UAVs are being employed in construction, who is using UAVs and why, the impacts UAVs can have on your company and the regulatory oversite of UAVs. Mike Bierschbach, director of fleet intelligence and technology at United Rentals will present a session titled: Where’s Your Telematics?

Getting Data out of the Shop and into the Csuite. In this session, you will hear examples of success stories, learn how to sell telematics benefits to key stakeholders and get supervisors and superintendents on board, explore data aggregation, and learn about timelines for implementation and resources.

Steve Riddle, operations foreman at Branch Highways, and Leo Wambold, technology consultant at James River Equipment, have put together a presentation called Accelerating Quality and Efficiency, Telematics Driving Your Field Service, which will detail how the Internet of Things is automating service and remote equipment monitoring; how big data helps dealers manage fleet analytics; how augmented reality, drones, and mobile service field apps will reinvent field service; and how to narrow the gap between the three legs of the equipment triangle – manufacturer, contractor and dealer.

The conference will be held at Memphis’s historic Peabody Hotel. For more information or to register, go to AEMP.org or contact Cindy Orr: Cindy@AEMP.org.

HORIZONTAL DIRECTIONAL DRILLS Designed for extended-range bores The 100,000-pound pullback Ditch Witch JT100 All Terrain is built for extended-range bores and installations of large-diameter pipe. The machine, with 12,000 pound-feet of torque, has a 260-horsepower Tier 4 engine. Using a two-pipe All Terrain drilling system, the drill can install pipe in challenging ground conditions, including solid rock. The machine’s anchor system eliminates the need for supporting equipment, saving setup costs. The JT100 uses Ditch Witch Power Pipe HD drill pipe, and has easy-to-access daily maintenance points.

36 percent more horsepower than predecessor Compared to its D9x13 predecessor, Vermeer’s compact D10x15 Navigator drill has more power and carriage speed, and lower sound levels. The 60-horsepower Deutz TD2.9 Tier 4 Final engine has 36 percent more horsepower. In addition, Vermeer also increased the thrust/pullback to 10,000 pounds, the unit’s maximum torque to 1,500 pound-feet, and the maximum spindle speed to 220 rpms. The carriage speed is now at 208 feet per minute. The drill’s compact size (12.5 feet long) and lowered sound levels are aimed at residential curb-to-home fiber and service work, which are typically less than 300 feet and 4 inches in diameter. The drill has an optional DigiTrak Aurora interactive, full-color touch-screen display.

pro pickup Nissan completes the roll-out of all Titan’s cab, bed, powertrain and grade level configurations, the pickup line will cover about 85 percent of the total light pickup marketplace.

Titan will ultimately be available in a total of three cabs, three bed lengths, three engines, 4×4 and 4×2 drive, and five trim levels, including S, SV, SL, PRO-4X and Platinum Reserve. Single Cab models go on sale this fall.

While the new single cab will be offered in both Titan XD and Titan configurations, each version will share the same cab dimensions and 8-foot pickup beds. However, each pickup gets a completely separate fully-boxed ladder frame chassis.

The TitanXD single cab, like the Titan XD crew cab, will be offered in a choice of two engines: the 5-liter Cummins V8 turbo diesel, rated at 310 horsepower and 555 pound-feet of torque; and the new Nissan 5.6-liter Endurance V8, rated at 390 horsepower and 394 pound-feet of torque. The Titan single cab, which has about a 1-foot shorter wheelbase than the XD, will be offered initially with the Endurance V8, with a V6 engine expected to be available at a later date. Dieselequipped models feature an Aisin six-speed automatic transmission, and V8 gasoline engine-equipped versions will use a seven-speed automatic transmission.

The Titan XD Single Cab, as well as the XD Crew Cab, comes with a choice of two engines, including this 390-horsepower Cummins 5-liter V8 Turbo diesel.

Along with a choice of 4×4 and 4×2 drive configurations, two grade levels will be available with both Titan XD and Titan Single Cab: S and SV, along with a number of optional equipment packages.

“The new Single Cab takes Titan into new territory, bringing the innovative design and bed utility that Titan has been known for to a wider base of commercial use buyers,” Miller says.

final word | by Tom Jackson

Tribes I

n his new book, “Tribe: On Homecoming and Belonging,” author Sebastian Junger suggests that many of society’s problems can be attributed to the fact that we no longer organize ourselves into small, fiercely loyal tribes as our prehistoric ancestors did for tens of thousands of years.

He’s not the only author to notice. In another recent book, “Bowling Alone,” Robert Putnam documents how almost everybody after WWII belonged to some organization like the Lion’s Clubs and the Jaycees. Today, those service organizations are almost extinct, as is that sense of community…but more importantly, so is the mental wellbeing that comes along with community.

Junger notes that when military veterans come home from war, those who return to civilian occupations, shorn of the tight knit tribe they knew in combat, are a lot more likely to suffer post-traumatic stress disorder than those who return and remain on active duty with their comrades in arms.

The reason I think this is relevant to us, is that the mental health of people in the construction industry – statistically speaking – is not good. Two key points from the Centers for Disease Control: • Compared to people in other occupational categories, people who work in construction have the secondhighest rate of alcohol and drug abuse. Fifteen percent of construction workers polled admitted to illegal drug use, 18 percent to heavy drinking. For the general population, those numbers are half that.

• People who work in construction have the second highest rate of suicide of any occupational group: 53 suicides per 100,000 people, vs. 13 per 100,000 for the general population…almost five times higher.

In today’s depersonalized, post-industrial world, it’s every man for himself. Junger writes: “Personal greed almost completely eclipses collective good.” And yet, he points out, the Comanches, the survivors of the

“

98 September 2016 | EquipmentWorld.com

siege of Sarajevo, the Marines at Fallujah, and many other groups throughout history have endured terrible experiences, yet suffered little PTSD. Why? According to Junger, it’s because these groups shared a collective identity. They are, or were, tribes: people who knew and experienced the same hardships, shared the same values, and helped each other through it all.

In the 19th Century, the Comanche’s and other Native American tribes would occasionally capture white women and children in raids. Some were treated harshly, but many were integrated into the daily routines of the tribe. And after only a few months of life in the tribe, most of these women and children refused to go back to “civilized” society. Recaptured by their distraught neighbors and relatives, most fled back to their Indian families and endured great difficulty to rejoin and stay with their new tribe.

Nature, it would seem, has hard-wired us all to belong to a tribe. “Humans don’t mind hardship, in fact they thrive on it,” Junger writes. “What they mind is not feeling necessary.”

When I go out for interviews, the best contractors always seem to have their team available. These team members are always die-hard, company loyalists.

They’re fun to be with, boisterous, and relentlessly upbeat. Sometimes crew members take me aside to brag on their boss.

That’s a tribe.

Construction can be a great career for many, but in terms of mental health, we have the second sickest occupational group in the country. Why? Shouldn’t construction be one of the most tribal, and hence mentally resilient occupational groups in the country, instead of the opposite?

I’d like to know why you think about this and what we should be doing about it. Email me at: tjackson@ randallreilly.com.
