Proposed aerial-lift standards would affect rental dealers, contractors
N
ew standards could soon be coming to the U.S. aerial work platform industry that will lead to major changes to the machines, how rental shops deal with their customers and how contractors plan projects. “The standards change is going to make a huge difference in the way work is done,” said Genie President Matt Fearon during a press event October 17 at the company’s Oklahoma City plant. The proposed ANSI 92 standards will not only alter machine design, but require additional training and responsibilities for contractors and rental companies. The standards even change the products’ names. No longer will they be called aerial work platforms, or AWPs. Instead, they will be known as “MEWPs.” That stands for “mobile elevating work platforms.”
What will the changes mean? Aside from the name change, rental dealerships and contractors will spend more time thinking about the types of aerial devices needed on a job. Currently, the main question is: How high does it need to go? But because the standards will lead to major technological changes to the machines and affect how they perform, contractors and rental shops seeking the right equipment will need to know such things as: What kind of terrain are you on? How much load are you lifting? How far out do you need to reach? “All of those questions are going to need to be a part of that conver-
Genie is preparing for future ANSI standards with its XC lineup of aerial work platforms.
sation,” says Adam Hailey, Genie director of product management. For instance, ANSI calls for the machines to be designed to address issues, such as wind effect on load. That may lead some machines to be rated for indoor use only, or outdoor-use machines may have more limited working height. Platform capacity would also be affected by the standards. Contractors and rental dealers would need to know how much weight they will actually put on the platform because the machine would automatically shut off if it exceeds its rated capacity. Currently, that task is left up to the operator, with many going above rated capacity on jobsites, Hailey says. “If a machine only has 500-pound capacity and you’re doing steel
work, you may need two machines or more cycles,” Hailey says. Hailey notes that machines built before the new ANSI standards will be grandfathered in and not have to be upgraded. The standards also call for more training for platform operators and occupants.
When will it happen? So far, it’s anybody’s guess when the ANSI standards will be published, after which the industry has one year to comply. A publish date had been expected this year, but appeals of the standards have delayed them. The earliest the standards could be published is January 2018, says Tony Groat, ANSI A92.22 Safe-Use Subcommittee chairman. –Don McLoud

Cat dealer given OK to establish distribution center in Cuba
Briefs
A
lmost two years after Caterpillar symbolically named Rimco its dealer in Cuba, Cat’s Puerto Rican dealer has been given the OK to set up a warehouse and distribution center in the country, the Miami Herald reports. According to the newspaper, the Rimco deal could be “one of the last signed before the Trump administration tightens up on business dealings with Cuba.” It’s anticipated that U.S. companies that have signed deals before the new rules are enacted will be grandfathered in. Caterpillar officials told the newspaper that current embargo law would not permit the manufacture of Caterpillar equipment in Cuba. During a news conference at the Havana International Fair, Ana Teresa Igarza, managing director of Cuba’s Mariel Special Economic Development Zone, said Rimco hoped to open operations in the zone next year, the newspaper reported. Equipment World reported in February 2016 when Cat named Rimco its dealer in Cuba that Caterpillar has been a vocal supporter of ending the trade embargo on Cuba, especially after then-President Obama reestablished ties between the United States and Cuba in 2014. 12 December 2017 | EquipmentWorld.com

Liebherr will add 2,240 employees by the end of this year due to a “very significant jump in orders” in 2017, says Stefan Heissler, member of the board of directors of Liebherr-International AG. In the first half of 2017, Liebherr saw a 6.4 percent year-on-year increase in total sales, and Heissler expects it to be “a record year.” For the third quarter of 2017, ASV Holdings is posting an 88.7 percent increase in new machine sales through its growing distribution network. Machine sales revenues jumped 60 percent to $19.8 million. Terex reports that income from continuing operations soared 70 percent in the third quarter of 2017 to $56.6 million – up from $33.3 million for the same period a year ago. Driven by strength in rental and distribution businesses, H&E Equipment Services posted third-quarter revenue up 5.9 percent to $259.2 million – an increase of $14.5 million over the same period last year. Caterpillar reported third-quarter sales and revenues rose 25 percent year-to-year. The company posted sales and revenues of $11.4 billion for third-quarter 2017, up nearly $2.3 billion for the same period last year. United Rentals saw a 16.8 percent surge in total revenue for the third quarter, climbing to $1.766 billion compared to $1.508 billion for the same period last year. The company says rental revenue is up by 16.2 percent. For more on each of these stories go to equipmentworld.com.

EDITOR’S PICK
CONFINED SPACE MOVERS
JCB has designed its new compact track loaders, the 210T and 215T, for working in confined spaces yet still able to lift a pallet of sod or brick. The machines weigh less than 10,000 pounds each and have 74-horsepower JCB Diesel by Kohler engines that require no diesel particulate filter or diesel exhaust fluid. The radial-lift 210T has a rated operating capacity of 1,900 pounds at 35 percent of tipping load and 2,650 pounds at 50 percent. The vertical-lift 215T has a rated operating capacity of 2,100 pounds at 35 percent tipping load and 3,000 pounds at 50 percent.
Skid-steer attachments made for excavators
Handles challenging jobsites
Caterpillar has introduced a universal coupler designed for use with 4-ton, 5-ton and 8-ton compact excavators. The new Cat Mini Hydraulic Excavator Universal Coupler allows for skid-steer attachments to be used and changed quickly on excavators. The coupler either pins to the stick or can be picked up with Cat’s Dual Lock Coupler. Manual handles lock the tools in place. Attachments compatible with the coupler include bale spears, pallet forks, and multi- and general-purpose buckets.
Case Construction Equipment has debuted its seventh C-Series model compact excavator, the CX30C, which has an operating weight of 6,020 pounds and a bucket digging force of 4,520 pounds. Powered by a 24.8-horsepower Tier 4 Final engine, the compact excavator can handle challenging jobsites but is small enough to operate in confined areas, the company says. It can also be towed by a pickup truck in most jurisdictions without the need of a commercial driver’s license. EquipmentWorld.com | December 2017 15

No trailer required Gradall has designed its newest version of the XL 4100 hydraulic excavator to be more fuel efficient, while still achieving speeds up to 60 mph on the road. The XL 4100 V excavator is powered by a 153-horsepower, Tier 4 Final Volvo Penta diesel engine, which achieves a 5 percent improvement in fuel efficiency over the IV model, the company says. The company designed the excavator so it doesn’t have to be trailered for getting to and from the jobsite. It also comes standard with Gradall AutoDrive, a pushbutton automatic transmission to make road travel easier.
Two-step emissions reduction Liebherr’s new PR 766 dozer succeeds the previous 416-horsepower PR 764 and is the newest of the company’s Generation 6 dozers, which debuted in 2013. Powered by a 422-horsepower, 8-cylinder Liebherr engine, the dozer meets emissions compliance standards in two technological steps, according to the company. First, using company-designed common rail injection and engine control enables Liebherr to minimize particles in the engine. The company also uses selective catalytic reduction-only, which allows it to forgo the use of a diesel particulate filter. The dozer has a hydrostatic drive, allowing the ability to run at a constant rpm and save fuel.
Grinding twice as fast Chicago Pneumatic’s new CP3330 and CP3340 vertical grinders can remove material twice as fast as similar tools on the market, the company says. The CP3330 comes with a 3.7-horsepower motor, while the CP3340’s motor packs 4.5 horsepower. The company also added safety features, including automatic shut-off to prevent the abrasive from over-speeding and causing accidents; a 1-inch-thick protective wheel guard; and a safety lever that can be easily used while wearing gloves.

Boosting drill production John Deere says it has upgraded its PA15B and PA30B planetary auger attachments to be more powerful and productive. They are part of Deere’s B-Series Worksite Pro attachments for skid steers, compact track loaders, compact excavators and compact wheel loaders. Deere boosted the hydraulic motor’s operating pressure to 3,100 pounds per square inch to increase digging power for both models. The augers work with such bit styles and diameters as standard 4- to 6-inch, 9- to 12-inch rock and frost, and 18- to 36-inch tree and shrub.
Lighter yet more powerful Vanair touts its new Reliant RS45 air compressor as being 55 percent lighter than its predecessor and having the highest cubic-feet-per-minute rating in its class. It also says it cut the weight of its Reliant RS85 in half while delivering 40 percent more power. Both hydraulically driven compressors’ canopies are made of aluminum, which prevents rust and helps reduce weight and fuel consumption. The RS45 delivers up to 45 cubic feet per minute of air power and 150 pounds per square inch of pressure. The RS85, which weighs 238 pounds, delivers 85 cubic feet per minute of air power.
Adding extra platform capacity Genie has unleashed a slew of improvements to its aerial work platform models under the XC label. The XC stands for “extra capacity,” and the company has added four telescopic boom models to the XC lineup – the S-60 XC, S-65 XC, S-80 XC and S-85 XC. It also introduces its first XC articulated boom model in North America, the Z-45 XC. All five models now have a greater lift capacity, of 660 pounds unrestricted and 1,000 pounds restricted. They are also designed to meet future American National Standards Institute (ANSI) standards for aerial work platforms. 18 December 2017 | EquipmentWorld.com

COMPACT EXCAVATORS: machine matters
| by Richard Ries
More of the same, only better
C
ompact excavators are already immensely popular because they lift, dig, trench, load and backfill. They run a wide range of attachments. They do all this in tight quar-
ters and can be trailered from one job to the next with a pickup truck. How to improve upon such capable machines? Find ways for them to do more and do it all better. The C Series from Case includes six models, from the 1.77-metric-ton CX17C to the 5.86-metric-ton CX60C. The lineup includes zero-, short-radius- and conventional configurations. All models have adjustable booms to allow offset digging. An auto-shift travel system enhances convenience for the operator when traversing varying terrain.
Overall design Zero tailswing was all the rage several years ago; it enhanced the ability of compact excavators to work in the tight, confined spaces typical for these machines. But zero tailswing has trade-offs, notably reduced lift capacity. So, reduced tailswing crept
into the market. Now there’s a full range of machines designed to accommodate all of the applications in which compact excavators work. “Our C Series mini excavators are available in zero tailswing, short-radius or conventional configurations,” says Ed Brenton, Case Construction
Equipment brand marketing manager. “There is also a long-arm option that includes a counterweight.” Brenton says this allows operators to do more work without having to reposition the machine. Adjustable booms allow offset digging, helpful when working next to buildings

The HPU8 electro-hydraulic pump was specifically developed by Wacker Neuson to ensure that the compact excavator delivers comparable performance whether operating by diesel engine or electrical power. The HPU8 is connected to the 803 by 39-foot hoses, allowing the excavator to still rotate 360 degrees.
or other obstacles, and Case C Series models all have adjustable booms. Case’s smallest model, the CX17C, sports another popular feature, a variable-width undercarriage (3 feet, 3 inches retracted; 4 feet, 3 inches extended) and adjustable blade. This allows the machine to fit through a standard 36-inch gate while providing maximum stability once in position. Landscapers and others working in developed environments place priority on this feature. Dave Young, excavator product marketing manager with John Deere and Hitachi, notes that the new Hitachi ZX30 and Deere 30G compact excavators have the same undercarriages as their bigger siblings, the ZX35 and 35G, respectively. One obvious benefit is a reduction in production costs, but the choice also provides greater stability to the new models. Despite the beefier undercarriage, the new models weigh only 7,200 pounds when equipped with cabs and rubber tracks, so they can be trailered with a threequarter-ton pickup.
All compact excavators have engines of less than 75 horsepower. Although engines below 75 horsepower have simpler emissions control systems than those of higher output, they’re still not one size fits all, says Andrew Earing, utility line excavator product manager with Komatsu. The company’s PC30MR-5 and PC35MR-5 rely on cooled exhaust gas recirculation (CEGR). The PC45MR-5 and PC55MR-5 have CEGR plus a small Komatsu diesel oxidative catalyst. The PC78US-10 and PC88MR-10 use those elements and a variable turbocharger. “The means of compliance changes to reflect the differences in fuel consumption,” says Earing. Earing says Komatsu offers three track types. The traditional rubber belt track is good for general excavation and landscaping. A hard rubber road track is available for urban and other developed environments to minimize damage to finished surfaces. And steel grousers are available for rocky conditions. A two-way blade is standard on all six models, while a four-way blade is optional.
Doosan offers two compact excavators. The 58.6-net-horsepower DX63-3 is a conventional tailswing machine weighing 6.3 metric tons. The reduced-tailswing DX85R-3 shares the 58.6-horsepower rating and weighs 8.6 metric tons. Doosan says the DX63-3 ranks best-in-class for over-the-side lifting performance.

Operator comfort Tom Connor, excavator product specialist with Bobcat, says cab size suffered when zero- and reduced-tailswing became driving forces in compact excavators. The industry is working to bring back roomier cabs. Even an inch matters, he says, especially with such details as foot room and joystick placement. With the larger cab, Bobcat has been able to use the same seat in compact excavators as in their skid steer and compact track loaders to increase operator comfort. Connor says the simpler emissions hardware of sub-75-horsepower engines takes up less space, making it easier to include larger cabs than if a selective catalytic reduction (SCR) system were in place. Another space-saving design in Bobcat compact excavators are the hydraulic reservoirs, which are one-third the size of those on most competitors’ machines, according to Connor. Where large reservoirs are often used to help control oil temperature, “there’s no need for a surplus of oil with Bobcat’s high-
Features to enhance operator comfort on the Cat 303E CR include an adjustable suspension seat, retractable seatbelt and adjustable wrist rests. The joystick and travel levers are ergonomically designed to reduce fatigue and improve productivity. With the Cat Interlock System’s hydraulic lockout lever in the up position, no operational function is possible, including travel.
performance cooling packages,” he says. Noise reduction is another component of operator comfort. One method of reducing noise is to create a quiet cab. Another is to reduce noise emitted from the source. Kobelco compact excavators from the SK17SR to the SK55SR feature the company’s Integrated Noise and Dust Reduction Cooling System (iNDr). The system uses a tightly sealed engine compartment, offset ducts and a muffler designed to slow and disperse exhaust for quieter operation.
Hydraulics Hydraulic systems and the electronics that control them have become far more efficient and powerful in recent years. Load-sensing hydraulics is one such example. Machine electronics allocate hydraulic resources based on the task being performed. Complementing the load-sensing hydraulics on many machines is an advanced hydraulic regeneration circuit. With regeneration, oil from the rod side is retained in the circuit rather than routed back to the tank
The Hitachi ZX30U-5 is powered by a Yanmar diesel rated at 23 net horsepower and meets Tier 4 Final emissions standards. Auxiliary hydraulic lines run to the end of the boom; quick couplers are optional. Maximum travel speeds with the two-speed drive are 1.7 mph in low and 2.7 mph in high.

The Hyundai R30Z-9AK features centralized lubrication and extended preventive-maintenance intervals. Long-life hydraulic oil provides 5,000 hours of service. Hydraulic filter changes come at 1,000 hours, and bushings get lubed every 250 hours. Power is from a Kubota D1305 Tier 4 Final diesel rated at 23.2 horsepower.
as the cylinder is extended. “Load-sensing hydraulics combined with regeneration provide speed, precision and power to improve cycle time and productivity,” says Jeff Jacobsmeyer, Kubota product manager for excavators, wheel loaders and backhoe loaders. Volvo also uses regeneration. John Comrie, product manager for compact excavators and compact wheel loaders, says it and other sophisticated hydraulic design strategies allowed the company to retain hydraulic performance, even on machines with horsepower dropped from 34 to 25 for emissions compliance. “Breakout and lift are equal to or greater than predecessor machines,” he says. Load-sensing piston pumps and proportional auxiliary hydraulics also maximize hydraulic performance and control, allowing operators
to do fine work even with the bucket. Multiple pumps were once common; a machine could have three or more. While some compact excavators still run multiple pumps – Takeuchi has four in most models – there’s a move toward single pumps. Improved pump performance and sophisticated flow control make this possible. “Customers sometimes ask if there’s a loss of performance with single pumps,” says Connor, “especially with high-demand attachments such as flail mowers, which are becoming increasingly popular.” Connor says the concerns are unwarranted, that modern single-pump systems, paired with appropriate main control valves, can outperform older multipump systems even in highdemand applications. Hyundai has nine models of 9A Series compact excava-
Among the features from larger machines making it into the JCB 45Z-I are steel bodywork, four-plate dipper construction and 100 percent graphite-impregnated bushings on the dig end. Compared to the previous 8045 ZTS, this new machine has a longer main boom and shorter dipper arm, yielding dump heights up to 13 feet. The 45Z-I has a transport weight of 9,700 pounds.
Observations from the guru
G
eorge Lumpkins has been in the industry for decades. He is now the general manager of marketing and product development at Kobelco. He offers these observations based on his wealth of knowledge and experience:
• Never operate any excavator with the travel motors in front and under the cab. There are a number of safety considerations, foremost of which is that travel motors are heavy and having them in the front will upset the primary balance of the machine. • Thumbs are common in North America but rarely used in other parts of the world. • North and South American markets are unique in that excavators are used to lift items around the jobsite. Standard and optional counterweights are offered that increase stability for these tasks. • Counterweights are useful to balance the weight of attachments, including thumbs and quick couplers. Regardless of the intent, never use a counterweight that exceeds the manufacturer’s maximum counterweight recommendation. • Compact excavators have taken over many applications performed by backhoe loaders. Pattern changers ensure operators can use the control pattern they prefer. • When running a hammer, set the return pressure to its lowest value for optimal power and durability and reduced heat.

Fuel efficiency is improved on the Komatsu PC55MR-5 compared to previous models through a Tier 4 Final engine, auto-idle shutdown and economy mode. A highstrength, X-track frame resists dirt and debris buildup. Standard Komtrax telematics provide operating data, including location, hours and status of the Komatsu diesel particulate filter. tors. The newest, the R30Z-9AK, has a list of more than a dozen improvements to its hydraulic system. Some, such as switchable control patterns (excavator/ISO and backhoe/SAE) are industry standards. Some enhance the operator experience, such as a circuit damper on the travel pedal to reduce shock load when starting and stopping in either forward or reverse. There’s also a selector valve to choose single- or double-acting operation of the auxiliary circuit. At least one feature simplifies maintenance; the swing motor is lubricated entirely by hydraulic oil, allowing the motor to be serviced when the hydraulic system is serviced. Controlling flow and pressure and the ability to choose between one- and two-way flow make it easier to match attachments to a machine and to receive peak performance from those attachments. But resetting the variables every time there’s an attachment change is time-consuming, so manufacturers offer programmable settings that can be matched to an attachment and stored in memory. Kubota, for example, offers the ability to program and store information for up to five attachments. Both the programming and the selection from among the stored settings are done through the in-cab monitor. A hammer circuit and selectable two-way hydraulics are standard on all six new models of compact excavators from New Holland. In addition, the largest models, the E57C and E60C, feature separate circuits with optional second auxiliary two-way circuits and an optional hydraulic quick-attach provision. The six models represent a doubling of the number of compact excavators offered by New Holland.
Powered by a Yanmar engine rated at 37.4 net horsepower, the Kobelco SK55SRX has two variable-displacement hydraulic pumps and two gear pumps, one of which is allocated for pilot circuits. Maximum digging depth is 12 feet, 10 inches, and maximum dump height is 14 feet, 3 inches.
The short-swing-radius Volvo ECR40D is compatible with a range of hydraulic attachments, including thumbs, breakers and tiltable ditching buckets. Both mechanical and hydraulic pin-grabber quick couples are available. Power is provided by a Volvo D1.7A engine rated at 24.8 gross horsepower. Maximum auxiliary flow is 17.2 gallons per minute.

New Holland’s line of compact excavators consists of six new models, from the 1.7-metric-ton E17C to the 6-metric-ton E60C. Features of C Series machines include an auto-shift travel system that responds to load and an Engine Start Limit anti-theft system. They also feature auto idle, which drops engine speed to idle when there’s no operator input on the stick and automatically returns to the throttle setting when the operator moves the stick.
Trickle down Technology is expensive at first but costs typically drop rapidly. New technology shows up first on larger equipment where its high initial cost is a small percentage of the total cost of the machine. As costs come down, these features can migrate to smaller, lower-priced machines. For example, Komatsu full-size excavators used common-rail injection first, while their compact excavators stayed with less-expensive unit injectors. As common rail systems and their electronic control modules came down in price, Komatsu added them to smaller excavators. Common rail provides cooler fuel and more precise injection control. This helps meet Tier 4 Final emissions requirements but also maximizes engine performance and reduces fuel consumption. The HiMATE remote management system (telematics) was first available only on Hyundai full-size HX crawler and HW wheeled excavators and HL900 Series wheel loaders. It has now been brought in as standard equipment on three of the company’s compact excavators, the R55-9A, R60CR-9A and R80CR-9A, as well as the R55W-9A compact wheeled excavator. Hyundai provides five years’ free use of HiMATE in its cellular configuration. Satellite connectivity is available with the purchase of additional equipment and a subscription. HiMATE can monitor a specific machine or any combination of multiple Hyundai wheel loaders and excavators.
The Kubota KX033-4 shares features with larger models such as a bigger cab, five dash-controlled presets for auxiliary circuits and a standard hydraulic diverter valve. Maximum auxiliary flow is 15.8 gallons per minute. Maximum bucket breakout force is 8,138 pounds. Power comes from a Tier 4 Final Kubota engine rated at 24.8 gross horsepower.
The 14.9-horsepower Yanmar diesel engine on the Takeuchi TB216H can be used for normal operations and to bring the machine to a site where the 14.2-horsepower electric motor is used to meet air-quality or other concerns. A 400to 480-volt, three-phase power source allows 100 percent emissions-free operation. Maximum bucket breakout force is 4,250 pounds. Maximum dig depth is 7 feet, 10 inches.

Some technology trickles down from other industries. The TB216H from Takeuchi is a dualpower machine with a 14.9-horsepower Tier 4 Final diesel engine and a 14.2-horsepower electric motor. The power sources feature separate pump groups, so performance is the same in either diesel or electric mode. Operational controls are also the same for each. The TB216H is well-suited for jobs with accessibility, noise or air-quality concerns. Examples include plumbing, landscaping and interior demolition. Wacker Neuson offers the 803 compact excavator as a conventional diesel machine or as a dual-power machine with a separate plug-and-play electro-hydraulic unit. Performance is comparable with either power source: maximum 5.3 gallons per minute and 2,466 pounds per square inch for working and drive circuits with the diesel engine; 5.2 gpm and 2,756 psi with the HPU8 electro-hydraulic unit. The HPU8 has a three-phase, 480-volt, 16-amp motor. Two openings are inset on the dozer blade of the 803 for carrying the HPU8. There’s also a lift eye on top of the unit and four tie-down lugs for safer transport. In May, Volvo unveiled the EX2 fully electric prototype compact excavator. The traditional diesel engine is replaced with two lithium-ion batteries totaling 38 kilowatts. Hydraulic cylinders are replaced with electromechanical linear actuators. “At this stage, the EX2 is purely a research project, and there are currently no plans for industrialization (production),” says Volvo.
Attachments Compact excavators are as much tool carriers as excavators, so most are available with two-way auxiliary hydraulics, which are required for common attachments such as thumbs and grapples. With the arrival of modern hydraulics, the catalog of attachments has grown significantly. Young says Deere and Hitachi will soon launch three plate compactors. The PC-4 will go on the 26, 30 and 35 models; the PC-7 on the 50 and 60, and the PC-10 on the 60 only. All pre-production work has been completed, but production had not started as of press time. To maximize flexibility with attachments, Doosan offers both hydraulic and wedge-lock couplers on their two compact excavators, the conventional-tailswing DX63-3 and the reduced-tailswing DX85R-3. A power tilting coupler is also available for the DX633. A roller switch on the right-hand joystick adjusts auxiliary hydraulic flow. Blade float is standard on both models so operators can smoothly back-drag an area.
Bobcat R-Series excavators use a standard dual-flange track roller system that extends the undercarriage structure closer to the track’s edge. This provides up to 15 percent more over-the-side capacity and greater stability. An integrated rear counterweight further enhances stability and lowers the machine’s center of gravity. The E32 and E35 are available now; an E85 will launch soon.
The new John Deere 30G brings G Series features to the 3- to 4-metric-ton range including standard pattern changer and standard hand-controlled proportional auxiliary hydraulics. Compared to the previous 27D, the 30G has 22 percent more bucket force, 11 percent more arm force and a 16 percent increase in hydraulic flow.

DITCH THE PAPER maintenance
| by Tom Jackson |
TJackson@randallreilly.com
It’s slowing you down, and the benefits of electronic equipment inspections can take your fleet management to the next level
T
here are plenty of obvious reasons to convert your maintenance and equipment inspection processes from paper records to digital: improved safety, shop efficiency, regulatory compliance and reduced downtime. What’s more, electronic records can be easily upgraded and customized into different fields. You can track hours per service or repair. Inspections can be shared with your people, vendors and dealers. Repair histories
can be called up instantly by anyone without having to thumb through hundreds of paper files. Inventory can be tied to the reports so you’re not caught emptyhanded on oil filters or other supplies.
Sharing is good But the most important reason to move to paperless equipment inspections may not be so obvious, yet it has the potential to significantly transform your operations and your relationships with vendors, customers and other divisions in the company. That benefit is the sharing of data, says J.P. Giometti, director of strategy and business development at the software company HCSS. “If you’re smart about how you share the data, you can create beautiful workflows in your company,” he says. Giometti, who shared his insights at the Association of Equipment Management Professionals 2017 Equip-

mentShift conference recently, says paper records have advantages and disadvantages, but their biggest weakness is you can’t share them. “When information can flow through your organization, you and your partners and vendors can do something with it,” Giometti says. And if you can automate some of the work you do, you can focus on what matters and not the tedious chore of processing paper, he added. Ben Tucker, director of equipment and facilities at Barriere Construction headquartered in Metairie, Louisiana, manages a fleet of about 250 onand off-road assets with a staff of equipment coordinators. Despite the company’s fleet size, it outsources all its maintenance and repair work. Tucker views his Bid2Win digital inspection reports as essential to communicating with these outside vendors. The efficiency and timeliness of the reports enable these service providers to maximize their time in the field, he says.
Destroying downtime Tucker started using paperless inspections and equipment management about a year and a half ago. Since then he has been able to cut the company’s percentage of machines undergoing emergency repairs almost in half. “For years, we couldn’t get our emergency repair rates below 5 percent,” he says. “Now we’re tracking at below 3 percent, and this year, we’ll probably finish up around 2 percent.” One of the most significant contributors to this improvement in uptime is the speed with which a paperless system records information. In the past, if an operator or technician reported a problem on the old paper-based system, it could take up to a week before the form reached a vendor or somebody who could get something done. “The paperless system streamlines the process of getting the information from the field to the vendors to get the work done,” Tucker says.
“It gets you on a more proactive timeline on certain things that are critical to the operation. It’s coming in real time.”
Accurate data The accuracy of maintenance data is also a key issue for fleet managers, says Derek Piwonka, division fleet manager for rail at Balfour Beatty in Colorado. As an example, if an hour meter is broken on a machine or a technician writes down the wrong hours or the wrong machine identification number on a paper form, those errors would get filed away in a paper system, possibly resulting in a missed oil change or service interval, Piwonka says. With a digital system tied to the machine’s telematics and GPS, such mistakes are easy to spot or immediately obvious. Alerts, notices of pending PMs or warnings can be sent automatically via email to everyone who needs to know. Piwonka started employing digital

maintenance recordkeeping in preparation for the electronic logging device mandate for trucks about two years ago and is rolling out a similar initiative to put all his yellow iron assets online using a Telogis Fleet and Compliance system. Before the company started digitizing the information and putting it on the cloud, he was faced with what he calls a “blizzard of paperwork.” Along with the company’s IT staff he’s also structuring his Telogis data to feed into the company’s enterprise resource program (ERP) to better share and inform people outside of the maintenance arena. With his yellow iron coming on line, Piwonka intends to perform detailed oil change-interval studies on his equipment. Accurately recording the hours of a large number of
machines will improve the quality of the study and greatly reduce the paper computations that doing such research by hand would require, he says.
Visual evidence In addition to pushing data around the internet, many digital maintenance and inspection systems allow the technician to take a photo of a problem or repair and upload it to the file or a repair or maintenance log. Having the ability to take photos helps a lot, says Tucker, especially when you are using outside vendors for service. A more advanced option for visuals comes via augmented reality by using screens or goggles such as HoloLens. “The more sophisticated companies are using augmented

The electronic files can also be retrieved and reviewed instantly. reality technology,” says Giometti. “It’s at an early stage, but being able to see a machine’s status simply by glancing at it through an augmented reality display could be incredibly powerful. I suggest you at least learn what is there so you can have a conversation with your vendors.” An intermediate step to autonomy is using a service like Facetime where a technician connects with an expert back in the office and shares real-time video images of a component or problem.

xperience was no match for the weight of a dozer when a 70-year-old heavy-equipment mechanic was fatally crushed while lowering a 44,200-pound dozer off a bottle jack. He had raised up one side of the dozer to replace the track adjuster. The air actuated bottle jack was rated for 30 tons but sat on a baseplate measuring approximately 8 by 10 inches. The saddle, where the top of the jack contacted the dozer, measured 2.5 inches square. The jack had a warning label that cautioned against performing work around equipment supported only by the jack. But the label was worn to the point of being unreadable. To start the repair, the victim jacked up the dozer and put cribbing underneath it. Once the cribbing was in place, the jack was removed. After installing the new track adjuster, another piece of oak cribbing was placed under the dozer, and the machine was jacked above the original cribbing. The

mechanic removed the original cribbing and began to lower the dozer on the jack, but noticed the undercarriage wasn’t lining up with the tracks below it. The mechanic got on a creeper and rolled himself under the dozer to better monitor the alignment of the machine with the track. That’s when the jack tilted, and the dozer fell onto the mechanic’s lower extremities. Coworkers reported hearing a loud bang and the victim yelling for help. They ran to find the mechanic pinned under the dozer. Emergency medical services were called, and the victim’s coworkers freed him by jacking the dozer back up. The victim was transported to a hospital but died three days later from his injuries.
How this accident could have been prevented • Never work around or under any vehicle or piece of equipment supported by jacks alone. A
jack’s only purpose is to raise the equipment. After that, cribbing or jack stands should be used to support the load. • Make sure that warning labels on jacks and all other tools and equipment are in good condition and easy to read. • All employees should be trained in the proper use of jacks and the procedures for using and removing cribbing. • Consult the equipment’s manual to determine the proper jack points and to make sure the machine is not unbalanced while on the jacks or cribbing. • While the job of lowering the dozer was considered a one-man operation, investigators suggested that having two people present might have deterred the victim from crawling under a 44,200-pound dozer supported by only a 2.5-inch square jack saddle.

22 toneladas se vencen sobre un pequeño gato de carga
Illustration por Don Lomax
L
a experiencia sirvió de poco ante un peso abrumador cuando un mecánico de maquinaria pesada de 70 años fue aplastado mortalmente mientras bajaba una motoniveladora de 44,200 libras de un gato de botella. La víctima había elevado el costado de una motoniveladora para reemplazar el ajustador de la banda de oruga. El gato neumático de botella estaba diseñado para 30 toneladas pero estaba colocado sobre una placa metálica que medía aproximadamente 8 pulgadas por 10 pulgadas. La montura, ahí donde la parte superior del gato contactaba con la motoniveladora, medía 2.5 pulgadas cuadradas. El gato tenía una etiqueta que advertía en contra de realizar trabajos en torno a equipos donde el único soporte era el gato. La etiqueta, sin embargo, estaba tan gastada que resultaba ilegible. Para empezar la reparación de la motoniveladora, la víctima la levantó con el gato y colocó debajo materiales de apuntalamiento. Una vez que los soportes estuvieron colocados retiró el gato. Después de instalar el nuevo ajustador de la banda oruga, otra pieza de madera de roble fue colocada como soporte debajo de la motoniveladora y la máquina fue elevada con el gato por encima del apuntalamiento original. El mecánico retiró el apuntalamiento original y empezó a bajar la motoniveladora con el gato, pero notó que el chasis no estaba alineado con la banda de orugas de abajo. El mecánico se acostó sobre una camilla rodante de taller para colocarse debajo de la motoniveladora y poder monitorear mejor la alineación de la máquina con la banda oruga. Ahí es cuando el gato se inclinó y la motoniveladora cayó sobre las extremidades inferiores del mecánico. Los compañeros de trabajo reportan haber escuchado un golpe fuerte y los gritos de la víctima pidiendo ayuda, y luego corrieron para encontrar al mecánico aplastado por la motoniveladora. Se llamó a los servicios médicos de emergencia y los trabajadores lo liberaron elevando de nuevo la motoniveladora con
el gato. La víctima fue transportada a un hospital pero falleció tres días después a causa de sus heridas.
Cómo pudo haberse prevenido este accidente • Nunca trabaje alrededor o debajo de ningún vehículo o maquinaria que esté únicamente bajo el soporte de gatos. El único propósito de un gato es levantar maquinaria. Después de eso, debería usarse algún apuntalamiento o soportes de gato para aguantar la carga. • Asegúrese de que las etiquetas de advertencia en los gatos y otras herramientas y equipos estén en buenas condiciones y sean fáciles de leer. • Todos los empleados deberían recibir capacitación en el uso adecuado de gatos y en los procedimientos para el uso y el retiro de materiales de apuntalamiento. • Consulte el manual de la maquinaria para determinar los puntos apropiados para la colocación del gato y asegurarse de que la máquina no queda desbalanceada mientras se encuentra sobre los gatos o el apuntalamiento. • Aunque la tarea de bajar la motoniveladora se consideraba una operación para una sola persona, los investigadores sugirieron que, de haber habido dos personas presentes, la víctima habría sido disuadida de arrastrarse debajo de una motoniveladora de 44,200 libras soportada únicamente sobre las 2.5 pulgadas cuadradas de una montura de gato.

DRONES: Three paving
A Kespry Drone 2S captures data for a construction engineering company.

n the commercial paving space, drones are taking off. And not just for marketing, says Ryan Anderson, owner of Premier Sealcoating and Line Striping in Oxford, Massachusetts. His company uses three drones for measuring, mapping and calculating layouts, as well as paving commercial parking lots and roads.
Drones have boosted his company’s productivity in the two years since he began using them, with faster measurements and projects completed sooner. “It’s a great technology,” says Ryan. “We bought it to help us with marketing and realized, ‘Wow, there’s so much more we can use this for.’”
Anderson uses mapping apps in his tablet that work on the same platform as the drones. Rather than walking around to measure an area, he sends the drone up. On his tablet screen, he sees the image obtained by the drone. He pushes points to put pins around the area to be measured and then gets a calculation of the square footage.

It’s easy to get the size, layout, pictures and videos to show his crew before heading out. “They know what to expect when they get there,” he says. “When you’re an owner and can’t be on every job, it’s nice to know that everybody’s on the same page before they get to the job.” Before drones, the manual process of sending someone on site to measure an entire parking lot could take all day. With drones, a contractor can document the entire lot in about 15 to 30 minutes, Anderson says. “Now, if we go to a big condo facility where there’s 70-some buildings, and they either need paving or sealcoating done, you have to find the general area of paving within that facility. Where before, one other guy and I would have to walk around with wheels all day, measuring, now I drive to the middle of the facility. I take my drone and put it on the Anderson roof of my truck,”
It’s easy to plan layouts and traffic patterns by looking at aerial photos like this one taken by a drone, says Ryan Anderson of Premier Sealcoating and Line Striping in Oxford, Massachusetts. Shown is the project his company recently completed for Crossroads School in Marlborough, Massachusetts.
he says. He sits in his truck while the drone does the work. “I fly it up a couple hundred feet, take a picture, go home and sit at my computer and do the rest.” Once Premier Sealcoating workers began using drones, they documented big projects with aerial photos on Facebook. Almost overnight, the company changed. “Now I have all these property managers calling, saying, ‘We’ve seen the pictures, and we know you’re capable of handling work like this,” Anderson says. Drone use can also help prevent mistakes. In one case, Anderson used his drone to take pictures before, during and after line striping. Chalk lines followed the plan, yet in the drone pictures he could see they were off. He called the engineer, who realized he’d made an error and had
Anderson correct it. That prevented the need to black out the mistake on new pavement. Customers want to know their facilities’ condition, and they want data and to run analytics so they can understand where they should be spending their money, Anderson says. “There’s really no better way to get this information so quickly with this quality we’re able to get. We’ve never been able to do it before.” Because drones are used for measuring stockpiles and job progress, he can see usefulness in road work. He’s meeting with municipal officials about the prospect of drones flying over townships to assess the condition of pavement.

road technology Paving America, which uses drones to create pavement assessments and budgets for commercial, industrial and retail clients. Clients include national retailers such as Walmart, Lowe’s and Home Depot, as well as real-estate investment trusts and property management companies. Rabine partners with Betterview, a San Francisco-based company with software that captures and analyzes detailed aerial footage obtained by more than 4,400 independent contractor pilots. Once the drone captures hundreds or thousands of images, Betterview and other companies like it can stitch them into an orthomosaic map with high-resolution imagery showing the layout of a parking lot. Zooming in is possible to see more detail, as well as measuring distances and dimensions for quotes. “The biggest thing for us is just how much more efficiently we’re able to get information in front of our pavement and stormwater engineers,” Rabine says. “Geography is not an issue. It could be Canada, Mexico, New York or California. I can get the same information on those sites in a few days; whereas before, it may have taken weeks to gather less information.” Previously, it could cost $2,000 to $4,000 to get somebody out to a property, and that would be Rabine

Paving contractor Ryan Anderson uses drone photos and an app downloaded to his tablet to quickly and precisely calculate the square footage of projects. Shown is mapping for his paving project for a school in Marlborough, Massachusetts. Anderson pushes points to put pins around the area to be measured and then the app provides the calculation – 73,937 square feet.
based on whether he could get the right experts on site taking photos, measuring the parking lot. “It was based on how many engineers you had and how many sites the client had,” Rabine says. His firm recently finished paving work for 40 or so distribution centers for a big-box retail chain. Using drones, he provided pavement assessments, “and that only took us a few weeks on about 40 of their sites, where in the past, it
could take close to a year to get all that information just because of all the travel involved, the cost, getting all the information back to the office.” The clients with whom he works could be a team of three or four people based in Atlanta or San Diego, for example, and manage thousands of properties nationwide. Often, those clients have never seen the properties they manage, Rabine says.

road technology “In the past, we’ve been our clients’ experts out in the field,” says Rabine. “We’ve sent project managers or engineers out to look at their facilities and assess them to help them build budgets. But with the use of the drone technology over the past two years, we dispatch drones, and they fly the site for us. It’s much cheaper, and we’re able to get information back a lot quicker.”
Drone demand growing in pavement work “Over the past 18 months, we’ve been using drones a lot,” Rabine says. The pace of his company’s drone use quickened in 2017 with more than 700 drone flights and assessments by early November and another 300 expected by year’s end. Using drones has transformed the speed in which his company works. In the past, Rabine Paving America would send subject-matter experts to walk sites, and when they spotted an issue, they’d photograph it from the ground. “We wouldn’t really see the full picture of what’s going on in the facility. But with drones, depending on the project size, we get anywhere from a few hundred to a few thousand photos of the entire site, and they’re all mapped out on Google maps so that you can see exactly where those photos are taken,” Rabine says. “Then, our team in the office and our pavement engineers go through photos, and that’s how we assess their facilities now – rather than sending anybody out on site.”

Using drones in his business was a learning process from the start; fine-tuning continues. “Now that we’ve got a good process around it, we’re serving our clients better and faster than ever before, and they’re loving it,” Rabine says. With momentum picking up, his company will focus more on this as an added service. “Until satellite images get a lot clearer and cheaper, this is going to take over the industry as far as property assessments go,” he says.
Volumetric calculations and more PLM Paving and Concrete in Pewaukee, Wisconsin, uses its drone for marketing, for volumetric calculations, for quoting excavations and for figuring how much trucking they’ll need as they remove piles, says PLM’s Jon Elliott. Earlier Elliott this year, PLM used its drone to determine the square footage of a gravel parking lot that was going to be paved and couldn’t be found on Google Earth, says Elliott, an FAA certified commercial drone operator. “It helps us in accuracy of measurements on some things that are tougher to measure from the ground,” he says. “I don’t know how to lay that out into cost savings – it’s just more about having better, more accurate information.”
Nationwide, a new perspective
D
rone manufacturer and service provider Kespry is seeing growing drone use by paving contractors, which are using them for volumetric and surface area measurement and to document project progress, says Jason Nichols, product marketing manager. The company is introducing many more features and capabilities for complex measurements, which could be generating greater interest, he says. Using drones can enhance worker safety, particularly when they’re deployed to evaluate material stockpiles in paving operations that produce their own asphalt, says Nichols, who has worked as an engineering geologist for construction site projects. “The additional high-resolution imagery to support the progress of your paving, as well as to help determine the conditions that are surrounding the site, really helps drive up the value for an aerial solution,” he says. Contractors also are keeping an eye on regulatory requirements developing for other uses of drones, Nichols said, as well as the evolving technology. “We’re starting to see in finer detail, and that’s where I think interest is going to lie,” he says. Giri Klausner, owner of Veuwr, a Florida-based video and aerial services firm, says that over the past 18 months his firm has completed more drone flights for commercial paving contractors. But he’s also finding that about half of the paving contractors he calls on already have their own drones or have a relative or friend who operates one for them, Klausner says. Costs for his firm’s aerial services range from $375 to $1,200 per job. Some assignments involve drones manually operated at low levels, while others involve drones taking off by themselves and flying higher on autonomous missions to produce a 3D map. Tom Clayton, director of training and member services for the Colorado Asphalt and Pavement Association, says he’s seeing paving contractors use drones to monitor plants and stockpiles. “They’re putting the drones up, flying over the stockpiles and doing their estimates of aggregate stockpiles.” The association has its own drone, which panoramically views members’ projects. “I fly it over projects as they’re under construction and as they get done,” Clayton says. “It’s just a totally different perspective.”

Our editors’ list of top roadbuilding products in 2017 features the latest pavers, rollers and other machines. Pavers
Vögele’s Super 1700-3i, 1703-3i universal class pavers Vögele’s new universal class 8-foot pavers, the Super 1700-3i tracked paver and Super 1703-3i wheeled paver, offer several new features the company says are firsts for the North American market. Vogele calls the canopied machines “universal class” because they’re designed for work in both confined conditions and on highway jobsites. The Super 1700-3i and 1703-3i have a maximum paving width of 19 feet, 6 inches with the front-mounted VF 500 Extending Screed and hydraulic bolt-on extensions. The ErgoPlus 3 allows the screed to be adjusted from 8 feet to 15 feet, 6 inches without the bolt-on extensions. The receiving hopper for the machines has a capacity of 14.3 tons with laydown rates of up to 770 tons per hour. The pavers have a liquid-cooled 4-cylinder, 179-horsepower Cummins diesel engine running at 2,000 rpm normally, and at 1,700 rpm in ECO mode. The Super 1703-3i is available in 6×4 and 6×6 drive.
Volvo’s new P4410B – a commercial-heavy highway crossover paver Volvo Construction Equipment’s new P4410B tracked paver adds a powerful engine to a compact machine platform. Designed for both light highway and heavy commercial, it features a front-extending screed and the ability to install most auto-grade and slope systems. The P4410B comes equipped with a 98-inch transport width. It’s 17 feet, 10 inches long and has a 155-horsepower Deutz Tier 4 Final engine that’s 5 percent more efficient than its predecessor. The P4410B features the Ultimat 16 screed that extends to 16 feet. With extensions, it offers an 18-foot paving width. Volvo also added 20-inch foldable walkways. There’s a 60-inch low deck, 360-degree visibility and swing console with controls common to Volvo pavers. The built-in SmokEater extraction system collects and disposes hot mix fumes.
Terex Bid-Well upgrades remote controls for roller paver lines Terex Bid-Well has three new remote control options that enable setting adjustments to its 2450, 3600 and 4800 roller pavers from ground level while paving. Two tethered control boxes can be attached in any position on the paver’s frame. Settings that can be changed include paver speed, engine throttle, power crown adjustment and paving width. Control options include an entry-level keypad control or a local control with a touchscreen display. Also available is a radio remote control panel that allows a worker to carry machine controls and operate the pave from ground level while anywhere around the machine.

continued GOMACO GP4 Slipform paver can pave 40 feet wide The 2017 GP4 is a slipform paver capable of paving a 40-foot width. It features a dual-telescoping roller frame with Smart Cylinders and Smart Telescoping for accurate frame widening and automatic width reference for easy steering setup. The roller frame telescopes up to 7 feet on each side for 14 feet total. It features Smart Pivot Arms for leg positioning and Smart Track Steering technology. The Extreme Steering capabilities work with the G+ control system for track location and position identification.
Rollers Case DV23CC and DV26CC: small-frame combo vibratory rollers Case CE has introduced two new combination vibratory finish rollers on a small frame. Designed to deliver high maneuverability and visibility, they’re equipped with the same control features found on larger counterparts. The machines are intended for work on walkways, residential driveways, bike paths, tennis courts, small parking lots and other small- and mid-size applications. The DV23CC and DV26CC rollers feature a front drum and rear pneumatic tires. Inline drums come with a tapered edge and high curb clearance to help in confined spaces, as well as adjustable scrapers, automatic vibration control and a pressurized water system. An iso-mounted platform reduces vibration and fatigue. The seats slide laterally to provide operator visibility on each side of the drum. The machines feature a 31.5-horsepower Tier 4 Interim engine, standard dual frequencies of 3,480/3,960 vpm and an automatic vibration control system.
Dynapac’s CC950D small project tandem asphalt roller; new colors Dynapac offers a small project tandem asphalt roller with its CC950D for bicycle paths, narrow roads, small parking lots and other hard-to-reach asphalt compaction applications. The CC950D offers 38-inchwide drums with a “high clearance” designed to allow it to work near curbs. The front drum vibrates at 4,200 vpm, or 70 Hz, while the rear drum is static. Dynapac added shock absorbers on the rear drum and designed “ergonomically positioned” steps to give the operator more comfortable access. It features standard foldable rollover protection system (ROPS) framing for low-clearance transport. The 20-horsepower Tier 4 Final engine is a watercooled, 3-cylinder, 4-stroke Kubota D722-E4B-KEA-2. Dynapac machines will also shed their former yellow color to sport red, white and gray, reflecting new ownership by the Fayat Group. The first in this new color scheme is the sixth-generation CC1100/1200 compact asphalt tandem rollers.

Wirtgen intros Hamm DV+ tandem asphalt rollers, expands lineup The Wirtgen Group introduced its DV+ tandem asphalt roller series, an expansion of the HD Compactline compact tandem asphalt rollers, a new H series soil compactor and the GRW 180i pneumatic tire roller. The DV+ series, represented in North America by the DV+70i VO-S, comes in three versions: the VV (double vibration), VO (one vibration and one oscillation drum) and VT (combination). All three can be configured as a ROPS or a cab. The machines have standard split vibration drums. Pivot steering with large angles and track offset allow sensitive steering in four modes. The HD Compactline features what the company calls a “wasp” waist to allow for articulated movement. The series includes the new HD 10C VT 39-inch model, which can provide compact near walls and high boundaries through inwardly offset drum suspension. The new models of the DV+ and HD+ tandem roller series – as well as the H Series soil compactors – make use of the Easy Drive operating concept. Its ergonomically optimized structure features a small number of language-neutral controls. All rollers are operated in the same way, with modifications to suit the specific functions of the individual series.
Volvo DD120C and DD140C rollers feature higher fuel efficiency Volvo’s new DD120C model features a 79-inch rolling width, while the DD140C has an 84-inch rolling width. Though these are the largest of Volvo’s asphalt compactors, they offer 20 percent more fuel efficiency over previous models via the Volvo D13J Tier 4 Final engine that offers high torque at low rpm. Both models have 4,000-vpm vibration frequency and a new water flow-rate calibration process for setting a minimum flow for spraying water on drums.

highway contractor Topcon ZPS concrete paver automation Topcon’s ZPS Concrete Paving System is a robotic total station that operates using less hardware than a traditional local positioning system or LPS. The system’s Z-Robot uses what Topcon calls Z-beam laser technology for tracking and guidance. The Z-beam provides optically based vertical control in addition to maintaining horizontal accuracy across the paver, which the company says cuts setup time in half. And the Z-robot eliminates the need for multiple robotic total stations to control the paver and another set of instruments for downrange transitions. On the paving machine, the Topcon Z-stack modular system integrates GPS, optical targeting and Z-beam reception into one unit or “stack.” The system does not require a separate base station and needs only one cable for power and connectivity. It also offers a wider working area – up to 150 feet more than traditional methods.

Paver Assist an added feature on Volvo VHD truck Volvo Trucks has added a feature that allows the paving operator to go directly from neutral to drive without a service brake application. The company has added auto-neutral and Paver Assist features to its I-Shift for Severe Duty, and I-Shift with Crawler Gears automated manual transmissions. Auto neutral and Paver Assist mark the latest Volvo VHD updates centered on the capabilities of I-Shift, an automated manual transmission (AMT). Volvo says auto neutral can help improve jobsite safety in many applications, including concrete mixers, when remote throttle is often used. The feature helps reduce the possibility of the truck moving as a result of inadvertent throttle application by placing the I-Shift transmission into neutral when the parking brake is set.
Philippi-Hagenbuch’s new concrete planer cuts energy consumption Philippi-Hagenbuch’s new truck products include the Rolling Wedge Concrete Planer, which the company says can reduce energy consumption by up to 80 percent. The Rolling Wedge does this by putting rock under tension, which reduces energy consumption by 80 percent from traditional planers when breaking through the material, the company says. The 2.5-foot-wide device can be mounted on rough-terrain forklifts, loaders or related equipment. The planer also comes in wider sizes and works with the machine’s hydraulics. It requires a 40 to 45 gpm flow at 2,500 psi. The device reduces the cost and increases speed for filling potholes, the company says. The cutters are made of hardened steel with carbide tips. The ¾-inch material cuttings produced by the machine can be reused for road base. The planer easily cuts to 3 inches deep and has options available for deeper cutting. The depth is controlled by adjustable shoes on each side of the machine, allowing it to plane at an angle or flat. 58 December 2017 | EquipmentWorld.com

operation in all terrains. The machine’s design also lessens the amount of dust traveling through its cooling system. Other features include a 755-horsepower Tier 4i Caterpillar engine, sealed cabin, joystick controls and four steering modes. The operator seat slides laterally and swings 90 degrees for achieving the right vantage point, and the operator platform slides 18 inches past the right of the machine for added visibility. The wheels are suspended by four independently controlled hydraulically adjustable leg assemblies that are bolted to the mainframe.

Joseph Palmer, McKinnley Excavating City, State: Chattanooga, Tennessee Year Started: 2002 Number of 5 employees: Annual revenue: $3 million to $5 million Markets served: Excavation, demolition and retaining walls
Precision excavation, machine technology key to Chattanooga contractor’s growth
J
oe Palmer wasn’t exactly your typical teen. Midway through his senior year in high school, Palmer took his savings from the many jobs he’d been working and bought a new set of wheels: a dump truck. With that truck and some compact equipment, Palmer started his company, doing hauling and light
demolition. By the grand age of 19, he landed a few demolition jobs that he now describes as “kind of funky.” “These were interior gutting jobs,” he says, “and they were right up my alley. My machines were small enough to get in those places. At the time, they were too small for my competition.” After a stint in the Army, Palmer
went back to working, using the compact equipment with which he was familiar, and establishing McKinnley Excavating, using his middle name for the company moniker. He now does a variety of excavation, demolition and retaining-wall projects, including a number of residential and commercial demolition jobs in nearby Gatlinburg after the EquipmentWorld.com | December 2017 61

continued wouldn’t crank. Stowers Machinery logged into the machine, found a shutdown error code and instructed them to reset the battery kill switch. “My operator kills the battery, gets back in and the machine cranks,” Palmer says. “Five minutes later, he’s back on the job. Two years ago, that would have been a 24hour downtime.” And now Palmer regularly uses a drone to shoot video and photos of his jobsites as a means of maintaining a visual record for himself and his clients. It’s also a great way to give his crew an overall site view of progress made.
Jobsite discussion: Palmer (center) with Tyler Yarbrough, left, and Thad Rounsaville. area’s devastating fires late last year. This year, McKinnley Excavating landed a National Park Service job to rehabilitate a historic building. Palmer attributes the growth throughout his 15 years of being in business to precision excavation, which he’s been able to do because of machine technology. “What I’ve enjoyed more than anything is getting GPS on the equipment in the past year or so and watching our clients benefit from that,” Palmer says. “We started with a Trimble 2D unit on our D6 and then with a 2D system on a Cat 314 for pipe work. It’s been nothing but success. It definitely speeds up the process.” At times, he’s been able to use the technology to complete site-prep jobs of more than one acre in half the time he originally estimated. While there was definitely a learning curve to adopting the GPS
technology, Palmer has nothing but praise for the support from his Sitech representative. “Every Sitech GPS case, whether it’s the rover or the base station, has their card clear taped on the inside,” he says. “And those guys answer the phone, or text us within 30 minutes.” “We’ve had to lean on technology, which can be expensive,” Palmer adds. The expense, however, can be justified by the increase in efficiency. This in turn helps keep prices in line. “You become a cheaper, betterquality provider,” he says. Still, the basic machine knowledge has to be there first, Palmer maintains. “If you hire a young guy and put him on a D6 with an auto grader and that’s what you teach him, that’s not enough. You’ve got to put someone on a straight dozer and let them muck out a pond or cut in a road, then you can start letting them advance to using GPS. We have to have people who are diverse.” Palmer has already experienced the benefits of telematics. On a recent jobsite, his Cat 314 excavator
Uniform fleet One thing Palmer says he learned in the military is the importance of uniformity. “It builds a team and an image and helps you identify strengths and weaknesses,” he says. Which is why Palmer says it’s important to keep a uniform fleet. In his case, that means Caterpillar equipment and Kenworth trucks. “We have three dump trucks that look identical; they were bought together,” he says. “People sometimes see two of the three on the road, but they think they’ve seen 12. That builds an image for your company that you’re growing.” Palmer also considers a uniform fleet important to employee morale. “If I tried to mix my fleet, I couldn’t imagine the impact on my employees and the changes to my maintenance costs,” he says. Palmer says if his company needs to rent a machine, he’ll buy it instead. “If a job’s producing profit, then I have to invest the profit. When you buy strong equipment, you should always be able to sell it. And if you’re renting, it’s hard to get the support back out of your dealer and your equipment because they just don’t have the money there.” There’s a definite pattern to his equipment buying cycle, Palmer says. “I’m Googling or YouTubing a piece of equipment at first,” he says.

EW1217_COY.indd 62
11/21/17 1:33 PM
A few days later, he calls the dealer and schedules a demo. If he’s satisfied, the machine will typically go on a rental purchase option. “Then it’s in the fleet,” he says. Major pieces in the McKinnley Excavating fleet include smaller dozers, compact track loaders, excavators and compact excavators. The majority of it is Tier 4 compliant. Even though most clients in Tennessee don’t have specific Tier 4 fleet requirements, Palmer believes his Tier 4 fleet – and the fact he runs his fleet on biofuel – gives him an edge. It’s a factor he believes helped him get work at the local Volkswagen plant.
On salary The McKinnley Excavating office is managed by Sarah Simpson, Palmer’s fiancé. “Our goal is to be that company that still has that personal relationship with its clients and goes above and beyond the scope of work to make sure it’s done properly,” Simpson says. Palmer takes an unusual approach with his team, paying each member
a salary instead of an hourly wage. “I’ve found that putting them on salary helps me lower my turnover,” he says. “People know that they may be offered $1 more next door, but they’re not going to get it for 50 hours a week. I pay them rain or shine. My mechanic, my office staff, everyone is on salary.” “Giving them a place to go has been my biggest thing,” Palmer continues. “If I can move the guys I have up, I can fill the gaps below them instead of hiring people over their heads.” Palmer says the Great Recession was a blessing. Still small at the time, it was easier to ride the downward spiral. “A lot of larger companies were performing in an environment where there was a lot of work and profit, and when the recession hit, they couldn’t keep traction. Because we were growing and watching every single dollar, that helped us put a high level of service in front of the client.” It didn’t hurt either that while larger companies were putting more hours on their equipment, Palmer was able to buy some new machines.
“Our equipment was never down,” he says, “and that helped keep our quality in place. Once you start that circle, it definitely feeds itself.”
Steady growth “We’ve grown a lot this past year, but it’s steady growth,” Palmer says. “I don’t believe in booming because your needs are always ahead of your cash.” Still, it’s hard to turn down work, especially with an existing client, so there’s always a balance. Palmer’s focus on customer service is guided by his philosophy of managing expectations. “I teach that to my employees so there’s buy-in to the process throughout the company,” he says. Says client David Bushman of Lennar Homes: “Palmer’s a young guy and I’m an old bird, and I learn from him all the time. I regularly tell him how much I learn from him, especially when I see him managing his people and his company.” Adds Candace Esparza with Durango Enterprises: “I would happily go to work for him. He gives his employees the opportunity to succeed and rewards them.”
McKinnley Excavating works in several markets, including excavation, demolition and installing retaining walls.

FIRST Navistar’s HV Series replaces WorkStar LOOK: with hopes of wooing drivers back
N
avistar’s new International HV severe-duty vocational truck is the latest truck introduction in the company’s efforts to rebrand its entire vehicle lineup. It was made available for limited on-course test drives to members of the media at a press event in New Carlisle, Indiana, in October. From the outside, the HV looks identical to its WorkStar predecessor. But under the hood and inside the cab, the HV offers a few notable updates. In addition to Cummins B6.7 and L9 engine options, the HV is available with Navistar’s new International A26 12.4-liter engine, replacing the N9, N10 and N13 engine options on the WorkStar. The HV borrows its cab interior from the International LT long-haul
The new International HV from Navistar looks similar to its WorkStar predecessor on the outside, but the company added notable updates under the hood and inside the cab to the severe-duty vocational truck. and RH regional-haul tractors, bringing over-the-road ergonomics and driver comfort features to vocational applications and helping Navistar reclaim market share in that segment it forfeited over the last six years in the wake of MaxxForce engine woes. A new premium gauge cluster display allows drivers to track trip data, fuel economy as well as customizable vehicle, engine, transmission and axle information. Up to 30 customizable and programmable switches can be added to the wing panel depending on the truck body. A new steering column-mounted shifter creates more driver leg room, and relocated pedestal mirrors provide better forward visibility with less neck movement to survey surroundings. The parking brake control valve
has been moved to the far right of the wing panel, making room for climate control and other buttons within closer reach of the driver’s seat. The HV sits between the DuraStar and the HX in International’s vocational truck lineup. The main differences from the DuraStar are the HV’s available power takeoff, A26 engine option and a GVWR of 73,000 pounds compared to the Daystar’s 54,600 pounds. The HX offers an additional 15-liter Cummins X15 engine and an aluminum cab over the steel cab HV. The International HV is available with regular, extended and crew cab configurations in four models with 107-inch or 113-inch BBC in both set-back and set-forward axle configurations.

4 technologies poised to transform the construction industry
I
magine a time in the near future when your handheld concrete drill contains the entire layout of a job in its CPU and guides you to where to drill the holes. You never have to measure, use a chalk line or set the depth of the drill. That’s part of the vision sketched out by Prakash Iyer, vice president of software architecture and strategy at Trimble Navigation. Iyer outlined his ideas as the keynote speaker at the Association of Equipment Management Professionals Equipment Shift Conference in October in San Antonio, Texas. These technologies are already here, Iyer says, and big changes are underway as these diverse applications are blended together and supported by the almost limitless capacity of cloud computing. Iyer mentioned four prominent technologies soon to change construction: artificial intelligence, the Internet of Things, computer vision and augmented reality.
Machine intelligence “I don’t like the term ‘artificial intelligence,’” said Iyer. “I prefer ‘machine intelligence.’ There is nothing artificial about it.” AI or machine intelligence has been around for decades, he says, but it wasn’t until the advent of cloud computing that the data collected by “learning” machines could be processed fast enough to deliver actionable results. “By 2020, a smart phone will have more computing power than today’s super computers, and that will enable a lot of AI,” he says. The Internet of Things, or IoT, is also getting a boost from cloud computing. “Soon there will be 1 trillion connected devices Prakash Iyer, vice president of software in the world architecture and strategy at Trimble constituting the Navigation, outlines his vision for the IoT,” Iyer says. construction industry’s near future, at the AEMP conference in San Antonio. “That’s 140 de-

‘New construction ecosystems’ Iyer defines augmented reality as a fusion of the physical world and the digitally designed world. He cites the collaboration of Trimble with HoloLens and Microsoft, which created a set of goggles that gives the viewer a 3D image of a digitally designed building, civil engineering project or mine. Viewers can walk around inside the digital buildings, see through walls and discover design flaws or conflicts that might not be apparent in 2D drawings. “All this technology, combined with cloud computing will create new construction ecosystems,” Iyer says. “It brings designers, contractors and operators into a seamlessly integrated work process. “Every stakeholder can share, review, coordinate anywhere, anytime.” EquipmentWorld.com | December 2017 67

Attachments supplement Combining higher force and capacity The Multi-DigNRip Bucket for backhoes and excavators is designed to replace hammers, blasting and rock trenchers by delivering wider, higher capacity rock ripping. Made by Leading Edge Attachments, the company says the bucket will save owners money through higher production because it rips rock up to four
times faster than hammers and 10 times faster than a single pointed ripper. The bucket has three high-strength teeth on the front and three on the back, and it rips rock one tooth at a time. It acts similarly to a trencher when the bucket is rolled. That rolling action creates a trench with relatively flat bottom and sides, the company says.
LEFT IN THE DUST. THE YELLOW DRILL WILL
Leading Edge designed the bucket’s back to conform to the arc of the rippers to prevent premature bottom wear. Because the force spreads evenly from one tooth to the next, the bucket goes easy on the machine it is attached to. The shank-on-arc (SHARC) technology with shorter shanks also delivers tooth force that is about 8.5 times greater than a standard five-tooth bucket, the company says. The shanks are the same distance from the stick pivot, so the bucket will rip a relatively flat bottom. The Multi-DigNRip was developed by combining the company’s high-force Multi-Ripper Bucket and its high-capacity DigNRip Bucket. It works on backhoes and excavators from 3 to 120 metric tons.
Clearing the air
Get a Dust Collection System.
Concerned about OSHA’s new crystalline silica regulations? Clear the air with E-Z Drill’s Dust Collection System. It easily connects to both new and existing units. You can breathe easy and know your jobsite meets OSHA Table 1 requirements.
E-Z Drill’s Dust Collection System attaches to any of the company’s drill models, from single- to five-gang machines, or can be retrofitted to attach to existing units, the company says. It is designed to meet federal silica dust rules that took effect September 23. The company says its exhaust systems had already been meeting those standards for 15 years. The vacuum system uses the same air compressor as the concrete dowel drill to collect dust directly from the drilled holes and store it in a collector. That reduces operator exposure and prevents dust from blowing into nearby traffic or, when working on bridge repairs, into nearby water.

Attachments supplement A ‘monster’ of a brush mower Eterra has added a 74-inch model to its Typhoon series of mowers. The Typhoon 74 is designed for heavy-duty skid steers and compact track loaders with at least 2,500 pounds of lifting power. The attachment requires 32 to 50 gallons per minute of hydraulic flow at up to 5,000 pounds per square inch of pressure. It can handle material up to 12 inches with the front gate removed and up to 4 inches with the gate closed. The 74 runs on a piston motor rated at 6,000 pounds per square inch. The mower features high-strength structural steel, double-reinforcement at stress points and a 1-inch-thick, T1-grade-steel blade holder.

Genius vs. Experience
E
lon Musk is one of today’s true geniuses, having developed the Tesla electric car, a reusable rocket system (Space-X) and the Hyperloop. But when a two-year backlog in orders for the new Tesla Model 3 emerged, the Wall Street Journal sent a reporter to the Tesla factory in Arizona to find out what was going on. What he found was shocking. The factory was a mess. Parts stacked up haphazardly on benches, tools randomly scattered on the floor. Knots of workers clumped around one car while other frames sat unattended. As it turns out, Musk, a genius in the fields of software and engineering, doesn’t have a clue on how to run a factory. No Kaizen method, no Six Sigma, no just-in-time inventory. It appears he’s trying to hand-build cars. And unless he can figure this out, and straighten it out fast, Musk’s dreams of being a dominant car manufacturer will drown in a tsunami of products made better, faster, more reliable and in much greater quantities by the likes of GM and Ford. What Musk needs is a team of good old-fashioned factory managers with deep experience in the nuts and bolts of the efficiency revolution that has been transforming manufacturers over the last 20 years. This matters to the construction world for a simple reason: the most aggressive and significant technology changes coming in the next decade are almost all focused on transportation and infrastructure. Smart cities, driverless cars and car-to-infrastructure communications will, if they achieve the potential that everyone expects, profoundly change the design of our cities and highways. Google, Apple, Microsoft and legions of other Silicon Valley companies are racing to dominate various aspects of this market. But Musk’s shortcomings would seem
to indicate that the geniuses of technology don’t have any experience in the field they’re trying to revolutionize. None, I suspect, has ever laid a brick, tied off a few acres of rebar, graded a site using survey stakes or wrestled with scheduling a half-dozen subs and suppliers on a jobsite. If Tesla can’t build a car, a relatively easy thing to do by today’s industrial engineering standards, how much worse is it going to be if the titans of tech try to manage the building of a new generation of highways and bridges with no field experience? The more I see of Musk’s endeavors in the press, the more I’m convinced his genius lies in ideas and his blind spot is execution. Execution is everything in construction. And you don’t get good at execution without time in the field, boots on, rain or shine, for years. What the technology companies working on smart-cities ideas need to do is immediately go out and hire a handful of construction veterans. Operations guys with real world experience in big infrastructure projects – mid- to upper-level people from companies like Fluor, Kiewit and Kokosing. Manufacturers of construction machines and GPS machine control systems have been doing this for the last two decades. Construction hands are plentiful in the technology departments of all the OEMs we report on regularly. These are digitally savvy people who also have dirt and diesel in their blood. It’s a great combination of skills and a very lucrative career pathway. But unless Apple, Microsoft, Google and others tap into the wealth of experience the construction industry has to offer, I fear all their drawing-board dreams of smart cities will wind up in dysfunction junction, years behind schedule, like the piles of parts that litter the floor of the Tesla factory.
