industry professionals seeking the latest and greatest equipment, technology and services to help them build and manage their fleets and enhance the profitability of their operations.

While the pandemic closed the show a day early, those who braved the virus foretell an industry eager to grow and learn regardless of any obstacles Mother Nature may throw in the way.

Construction backlogs leading up to the show were steady and much of that demand still exists. As of the time I was writing this, most states were largely exempting construction projects from shutdowns and a large chunk of work continued to progress. And while the world experienced a momentary lull as nations across the globe grappled with containment, the construction sector kept pushing ahead, carrying a sizable portion of the burden of sustaining some semblance of U.S. economic activity.

It’s too early to know what lingering impacts the steps taken to contain the coronavirus and resulting COVID-19 may have on global and U.S. economic growth long term, or how it might affect future project development; opinions vary widely depending on which economist you read or talk to. But the need to find ways to effectively oversee and grow construction operations remains intact.

The industry recognizes it must continue to innovate in order to curb costs and enhance production and efficiency, as well as develop solutions to overcome the seemingly ever-present workforce shortages.

As CONEXPO-CON/AGG showed, solutions are available to help the industry accomplish all of these objectives, whether it’s through enhanced grade control systems, automation, electrification, robotics or other equipment and technology developments. We’ve provided a glimpse of some of the potential solutions on display within the pages of this issue, with more to be featured in the months ahead. Additional details on what we saw on the show floor can also be found at www.ForConstructionPros. com and on our sister site, www.

OEMOffHighway.com.

With any luck, by the time you read this the coronavirus will be a bad memory of a strange and interesting time in our history, and the U.S. and global economies will be in recovery mode.

Regardless, we’ll keep pushing forward to deliver the information you need to be successful well beyond the current crisis.

How E Close Is Electrified Equipment to Your Site?

lectric machines may still seem like a distant prospect, but more and more OEMs are bringing electrified equipment into their portfolios as the trend gains steam. According to Bart DeHaven, national sales rep for Kato, a number of factors are contributing to the growing interest in battery-powered machinery. “Between tightening emissions standards and electric [and/or] battery machines that are becoming more economical, the bottom-line value to a contractor continues to improve,” he states.

“As that value proposition grows, we’re seeing a greater number of contractors demanding electric and battery options.”

In line with emissions reduction benefits, as areas become more populated and noise restrictions are more commonplace, electric machines will continue to grow as a market segment solution, says Lee Padgett, product manager, Takeuchi-US. The most prominent subset of equipment leveraging electric power is the compact excavator market. Rodolfo “Tito” Sosa, product specialist and sales trainer for Hyundai Construction Equipment America, notes that the 1.5- to 2-ton machine size has been a particularly strong area of focus.

When considering electric equipment, application is key.

m i f

More and more OEMs, including Hyundai, are working to add electric-powered compact equipment to their portfolios. Learn more in the video at www.ForConstructionPros.com/21122262.

“Equipment owners need to look at whether they have the amount of jobs that require a zero-emissions machine to justify the added expense of an electric machine,” Padgett states. “It may be more cost effective even with the lower

maintenance cost to rent vs. own if they do not have steady work for the machine.”

As of right now, electric compact excavators (and electrified vehicles in general) are a small portion of construction vehicles used and are primarily for niche circumstances — namely those that necessitate low noise and emissions. But as DeHaven points out, there are other benefits for prospective buyers or renters of electric equipment, such as reduced maintenance and fuel costs.

The potential for electrified equipment like compact excavators to become the rule and not the exception stems from technology limitations. It’s no secret that battery technology is a significant detriment to widespread implementation due to high cost, slow power intake (charging time) and capacity issues for functions demanding high power output, such as digging.

Consider that a recently released electric compact excavator claims to be fully charged in three hours and able to perform eight continuous operation hours.

Comparing three hours of charging to the few minutes it takes to fill up a diesel tank, it’s easy to see why faster

“Production of battery packs and components is simply more expensive than a tethered or diesel-powered equivalent,” says DeHaven. “That cost is offset when you consider the reduction in emissions and noise pollution. However, the initial startup is more than we’re all used to paying.”

In the end, it’s not a surprise that many feel as though

electrified equipment is still years away from being a viable consideration with the high upfront costs and long return on investment. But as more jobs require low to no emissions of both pollutants and noise, electric vehicles will become more in demand, especially in the compact market — and, it would seem, starting with compact excavators. ET

Because of the higher initial purchase cost, it can be more cost efficient for contractors to rent electric-powered equipment.

CASE SPARKS EQUIPMENT EVOLUTION Perhaps the biggest jaw dropper at CONEXPO was “Project Zeus” — the 580 EV (Electric Vehicle) backhoe-loader unveiled on Day 1 of the show by Case Construction Equipment. The 580 EV offers power and performance equivalent to the company’s other backhoe-loaders while providing considerably lower daily operating costs and producing zero emissions.

The 580 EV is powered by a 480-volt, 90-kW-hour lithium ion battery pack that can be charged by any 220-volt/ three-phase connection. While applications will vary, each

The battery separately powers the drivetrain and hydraulic motors, resulting in hydraulic breakout forces equal to diesel-powered machines and improved performance during simultaneous loader and drivetrain operation.

Though an electric backhoeloader may seem unusual at first glance, Eric Zieser, director – global compact equipment product line, sees this machine

type as an obvious choice for electric power. “The backhoe-loader is perfectly suited for electrification as the varied use cycles, from heavy to light work, provide an excellent opportunity to convert wasted diesel engine hours into zero consumption battery time, yet provide the operator with instantaneous torque response when needed,” he states. “At low idle a diesel Liebherr US engine has reduced torque and requires time for the engine to ramp up to meet the load demands. Electric motors, on the other hand, have instantaneous torque and peak torque available at every operating speed.”

You might assume the 580 EV is a concept or prototype, but it’s not. Two units have already been sold to utilities in the U.S., and Case has the capability to produce additional units throughout 2020 before ramping up production to meet demand in following years.

T

he time frame from January through March is typically a busy one for commercial truck announcements. Major trade shows including World of Concrete, the NTEA Work Truck Show and CONEXPOCON/AGG provide the forum for manufacturers to display their latest wares.

Usually, there are one or two major announcements that dominate the headlines. This year, however, there was a rapid succession of products and options being introduced that have the potential to shake up the commercial truck market.

MACK RE-ENTERS MEDIUM-DUTY SEGMENT Mack Trucks is entering the Class 6 and 7 medium-duty truck market with the MD6 and MD7 models. The MD6, a Class 6 model, has a gross vehicle weight rating (GVWR) of 25,995 lbs., while the MD7, a Class 7 model, has a GVWR of 33,000 lbs.

Available in 4x2 configurations, the MD6 and MD7 feature a sharp wheel cut for enhanced maneuverability in crowded urban settings. The MD Series cab design features a short bumper-to-back-of-cab (BBC) measurement of 103 in.

Mack matched the exterior bold look and styling of the Mack Anthem, Mack’s highway model, as a basis for the grille and hood design found on the MD Series.

The new trucks are offered with the Cummins B6.7 L engine with 220 to 330 hp and 560 to 660 lbs.-ft. of torque.

Allison automatic transmissions are utilized, with the 2500 HS standard and the RDS an available option. Both the front and rear axles are from Meritor.

“We’re now absolutely able to provide a single-source solution for all of our customers with the addition of the medium-duty [truck],” says Jonathan Randall, senior vice president, North American Sales and Marketing, Mack Trucks.

The company is also working to reduce the effects of the rigorous demands of the jobsite by bringing its Mack Command Steer active steering system to the Granite axle-back models. Mack Command Steer reduces driver fatigue and can help cut muscle

strain up to 30% by combining an electric motor with the existing hydraulic steering. Mack Command Steer for the Granite axle-back models will be available for order in the third quarter.

“With the added steering assist from Mack Command Steer, we are able to reduce driver effort by 85% and significantly improve driver productivity and jobsite safety,” says Roy Horton, Mack Trucks director of product strategy.

The active steering system monitors terrain, driver inputs and environmental elements more than 2,000 times per second through sensors found throughout the truck. Based on that input, the system provides variable steering effort through its electric motor, which applies additional torque as needed to the steering.

In addition to significantly reduced steering effort at

slow speeds, the system also helps filter out uneven terrain such as the holes, dips and ruts common to most jobsites. When such an irregularity is detected, the system reacts to counter the steering force, smoothing steering feedback and reducing the possibility of steering wheel “kicks.”

“While drivers will experience a significant reduction in steering effort, particularly on uneven jobsite surfaces, Mack Command Steer brings many benefits to on-road driving, as well,” Horton says. “The system will also compensate for situations, like strong winds and crowned roads, helping drivers maintain greater control so they can focus on the task at hand.”

The system also features a return-to-zero capability that automatically returns the steering wheel to the zero or center position in forward and reverse.

This helps simplify tight maneuvers such as backing a trailer or positioning a dump or mixer to unload.

VOLVO REDESIGNS VHD Volvo Trucks North America made the most significant evolution of its VHD vocational offering in decades. The new VHD provides a number of notable upgrades, including: An updated exterior gives a modern look. The VHD has a new grille design, as well as new LED high/low beam headlights. The fully sealed headlamp component offers a brighter, more focused beam for increased visibility.

An available de-icing feature burns through ice and snow that accumulates on headlamps in colder weather.

Safety and productivity features for the vocational industry include Volvo Dynamic Steering (VDS) and the next generation of Volvo Active Driver Assist (VADA).

The VDS system delivers a safer, more comfortable driver experience by adding torque to reduce steering strain at low speeds and remove vibrations caused by rough terrain.

The next-generation VADA provides integrated radar/ camera capabilities, automatic emergency braking, highway departure warnings, adaptive cruise control and more.

A new VHD bumper features a 45-mm tow pin rated for a full 80,000 lbs. Responding to customer requests, the tow pin allows for a quick pull out of sticky situations, thereby increasing uptime and drivers’ peace of mind.

A redesigned interior offers improved driver comfort and productivity. The truck’s ignition has been moved to the lower left-hand side of the dash, while the steering wheel buttons are more touch-friendly and clustered intuitively to help drivers feel more confident.

The Volvo I-Shift transmission with crawler gears adds one or two gears to the 12-speed I-Shift transmission, enabling the VHD to start on steep grades, provide low-speed control and reach maximum highway speeds with faster rear axle ratios.

WESTERN STAR TEASES NEW TRUCK Western Star provided a sneak peek of its newest model in its vocational truck product portfolio. The truck was scheduled to be fully unveiled in summer 2020.

The new Western Star truck is part of parent company Daimler Trucks North America’s (DTNA) recently announced segment strategy to deepen its focus on segment-specific needs. The newly unveiled structure strengthens DTNA’s customer- and application-focused commitment to vocational customers, while the new truck leverages all of the global design and engineering resources of Daimler.

In 2019, Western Star introduced an enhanced version of its best-selling truck model, the 4700, which includes updates such as a refreshed interior, more powertrain options, additional truck equipment manufacturer-friendly features, and new active safety features.

The newest truck will continue the company’s emphasis on productivity, driver comfort and

safety while retaining the distinctive styling of a Western Star truck.

INTERNATIONAL INTRODUCES LIGHTWEIGHT MIXER SPEC International Truck introduced a lightweight spec for its HV Series. The HV50B mixer package removes over 1,000 lbs. of weight from the vehicle, with engineering optimizations that allow drivers to haul up to 9.75 cu. yds. of concrete while staying under 66,000 lbs. GVW. The result of these changes means that customers currently only able to legally carry 9 cu. yds. of concrete will be able to increase their revenue by $750 per truck per day.

The spec also includes fringe benefits such as enhanced safety due to improved line of sight for the driver.

The idea stemmed from a conversation between the company and a potential customer.

“A major concrete producer was excited about our HV series but had some constructive feedback regarding the chassis weight and line of sight for their application,” says Mark Stasell, vice president, Vocational Truck Business, Navistar.

The spec is designed specifically for saving pounds that don’t affect the integrity of the vehicle.

It features a lightweight aluminum bumper that is used on the International HX series. The team also optimized the front suspension components, allowing for a lower hood height, increasing visibility for the driver and improving safety on the work site.

KENWORTH WITH BENDIX WINGMAN FUSION SYSTEM The Bendix Wingman Fusion advanced driver assistance system with an enhanced feature set is now available on select new Kenworth heavyand medium-duty trucks. The system is standard for the onhighway flagship Kenworth T680 and optional for the T880 vocational and T270 and T370 conventional mediumduty models.

Kenworth customers will benefit from the new Highway Departure Braking (HDB) and Multi-Lane Autonomous Emergency Braking (MLAEB) features available in the latest Bendix Wingman Fusion.

HDB builds upon Bendix Wingman Fusion’s existing lane-departure warning capability. It provides auditory and visual alerts to the driver and, if necessary, applies the foundation brakes to reduce vehicle speed if the system determines the vehicle has left the roadway unintentionally.

MLAEB can help the driver mitigate the first, and potentially, second, collision situation when more than one highway lane is blocked. Once a collision-mitigation braking event begins and the driver steers

into an adjacent lane to avoid the forward vehicle, Bendix Wingman Fusion’s new MLAEB feature continues to apply the brakes, if needed, when it detects another forward vehicle blocking the path in the new traffic lane.

In addition, Kenworth has introduced an optional diesel exhaust fluid (DEF) tank with integrated steps designed for the T680 and T880. With this option, the access steps to the deck plate are mounted directly over the DEF tank without requiring additional frame space. The placement of the steps can free up as much of 16 in. of valuable frame space. The resulting shorter wheelbase can further enhance the maneuverability, especially in tight urban areas or jobsites.

The option is available with Kenworth’s 21-gal. medium-size aerodynamic DEF tanks. It is not available with full or partial chassis fairings.

A factory-installed twin steer configuration is also available for the T880. Available as a day cab, the T880 Twin Steer with setback front axles is suited for crane, mixer and other vocational applications that require 86-in. axle spacing to meet local bridge laws and enhance overall load carrying capacity.

The T880 Twin Steer provides 40,000-lb. rated front axles, springs and steering gears. The front suspension is equalized between the front and rear steer axles for greater Kenworth

A T880S Twin Steer model with set-forward front axles and 61-in. axle spread was introduced in 2018.

AMERICAN EAGLE CLEAN POWER SERVICE TRUCK SOLUTION American Eagle, a division of Stellar Industries, introduced the Hybrid Power Source (HPS), a self-contained hydraulic power source that utilizes automotive-grade lithium ion technology to provide a system that is low-voltage, anti-idle compliant and quiet during operation. The HPS allows companies to operate hydraulic equipment without the use of the chassis engine.

Using the reliability of Volta lithium ion technology, the HPS offers up to eight hours of run time and more than 10 years of life. With 13.5 kWh of output, operators will have plenty of available power to meet their equipment needs.

The HPS offers multiple options to keep the unit charged. It comes equipped

TRU CKS & TRANS PORTATION

with an integrated 48V chassis alternator, allowing the system to be charged from the chassis on site or while driving to the next jobsite. Shore power charging is also an option with a standard 120V, 15-amp connection to enable the unit to slow charge while parked for the night or when chassis engine charging is unavailable.

When using the HPS, the system allows for 100% emissions-free operation, reduced fuel consumption, decreased engine maintenance costs, quiet operation and compliance with idle mitigation requirements because the chassis engine is no longer needed during equipment operation.

The utilization of a 48V system enables the entire unit to qualify as low-voltage, removing the need for compliance with high-voltage placarding.

The HPS is prepared for multiple climates with internal thermal protection to protect the energy packs’ core temperature in extreme heat or cold. The system also comes equipped with a heating system that will automatically activate to keep the unit’s core temperature above the minimum for charging.

Simplicity in upfitting a fleet is made easy when it comes to the fully self-contained HPS unit. Weighing only 790 lbs. and measuring 47 in. long x 21 in. wide x 28 in. high, the system can be sidepack-mounted or mounted in the load bed lengthwise.

package comes with payloadincreasing options such as a compact work bench bumper and a redesigned lightweight customizable bolt bin offering.

It’s also available with the new CAS40PL air compressor. The new compressor features an aluminum canopy, which reduces its weight more than 40% over the previous model.

The combined result is even greater functionality. “These innovative product enhancements increase the payload capability of our Dominator I mechanics truck package by approximately 1,000 lbs., while providing our customers with more options to meet their field service needs,” says Justin Anderson, IMT marketing representative.

VMAC TO RELEASE HVAC COOLING SYSTEM FOR THE MULTIFUNCTION VMAC plans to release its new HVAC Cooling System for the VMAC Multifunction in time for summer 2020, enabling its 6-in-1 multi-power system with Cat Power or Kubota engine to provide truck cab cooling.

TIPS TO

MAXIMIZE LOADING EFFICIENCY In addition to wheel loader selection and operator technique, technology advancements have a significant productivity impact.

M

any variables including loader size, bucket size, lift height, truck size, jobsite layout and underfoot conditions can impact the productivity of a material loading operation.

“Improperly sizing a loader (loading tool) to a truck (hauling unit/target) can be detrimental in obtaining efficiency of a jobsite,” notes Scott Schmidtgall, product application specialist for medium wheel loaders, North America, Caterpillar. Many items must be considered to make a decision on what bucket size and loading height constraints need to be met. “Know what your current actual production targets are as well as what the future production is intended to be. Material density, production targets, peak times, realistic idle times all come to mind very quickly as areas that cause pain if they aren’t understood well.”

Define production requirements for the operation. Once that is established, then match machine size and bucket size in relation to the material being handled and the necessary

fer

discharge height. “Matching the machine and bucket with the production requirements and considering the working schedules of the operation will help put the right machine on the site,” says Nick Rogers, product specialist/inside sales coordinator, Liebherr USA, Co. Construction Equipment Division.

“Ensuring the loader is properly sized for the application and equipped with the appropriate bucket, ground-engaging tools and tires is an important first step for optimizing loading efficiency,” says Grant Van Tine, product marketing manager, wheel loaders, John Deere Construction.

“By understanding the correct pass matching between your truck and loader, you’ll get the most amount of material loaded in the shortest period of time,” says Chris Connolly, product manager, wheel loaders, Volvo Construction Equipment. “This is especially critical in highproductivity applications like a quarry or plant.”

Yet, there is more to sizing a machine than simply productivity. “The loader must be able to

handle the volume of the material, both in terms of power and stability,” says Connolly. “If the machine doesn’t feel stable while lifting or traveling with a loaded bucket, it is not only dangerous, but can also shorten the service life of the machine significantly. This can also have a major impact on the confidence level of the machine operator.”

Typically, a wheel loader is sized based on the common truck size and traffic at the site. If trucks are not lined up and waiting throughout the day, you may be able to use a smaller loader.

“There are several factors that need to be considered including weight capacity of the truck, the materials that will be loaded, and their densities,” says Van Tine.

“Often, there is a desired number of passes to load trucks (two to three, for example). From that, customers will choose a loader that can handle the bucket size needed for their materials and meet the loading height requirements of the trucks.

“In some applications, height is the most important factor when sizing a loader,” he adds.

The latest advancements in wheel loader technology plus proper training on features and settings can help you get the most out of your operators and machines to maximize loading efficiency.

t o e J t r

O Some manufacturers offer highlift models specifically to address these applications.

One often overlooked factor is the correct tire pressure for the application. “Tire pressure impacts traction, stability, fuel consumption and productivity, in addition to wear,” says Van Tine.

The data that Volvo’s onboard scale provides can be viewed remotely through the use of a cellular data connection or by push download directly from Volvo Co-Pilot.

OPERATING TIPS Experienced operators yield maximum efficiency. “The equipment operator’s experience, operating technique and operating knowledge all influence fuel consumption, productivity and resulting fuel efficiency,” says Schmidtgall. “One study indicates efficiency can vary up to 40% between different operators

overshadows all the others,” says Schmidtgall. “There are many technologies that come together at this location of the pile dig — and even beyond into the whole tractor cycle for a holistic approach to efficient loading.”

SET UP FOR MAXIMUM EFFICIENCY Make sure you set the jobsite up for maximum efficiency.

“Having the truck positioned at a 45˚ offset to the pile and within about two bucket widths is a good target,” says Schmidtgall.

“Caterpillar’s ground-up design of machine geometry, kinematics, power, breakout force, implement speed as well as steering responsiveness are designed to get the truck loading process done efficiently in a 30-second cycle. This means the power to dig, load, travel and lift controllably to a dump height prior to the target and then dump safely and back away for a repeat.

“Dedicated steering and implement pumps allow us to have enough speed and control to provide the operator what he needs, when he needs it — even getting to 20-second cycles can be doable,” he continues.

“But efficiencies start to wane at this point, meaning things like operator fatigue, tire life, fuel efficiency, etc., begin to be sacrificed.”

Y-pattern (also known as V-pattern) loading is typically the most efficient way to load trucks with a wheel loader. “The truck should be positioned at a 30˚ to 45˚ angle with tires just off the edge of the pile,” says Van Tine. “Keeping the V-pattern tight and limiting travel of the loader is key to reducing cycle times, fuel consumption and tire wear. Ideally, there should be just enough travel distance to the truck to allow the loader operator time to raise the boom to the dump height position just before approaching the truck.

This ensures there is no loss in momentum and provides the fastest cycle times.”

“The trick as a loader operator is keeping the trucks in a consistent position as to not make the Y-cycle too big or too small,” says Connolly. “It is possible to be too close to the truck and pile, which makes

www.ForConstructionPros.com

ET0420_28-30_Loaders_CB.indd 29

maneuvering at an efficient speed difficult. This can also force the operator to have to steer more than necessary, which will slow the cycle time.”

“After filling a truck, operators should keep the bucket loaded in preparation for the next truck,” adds Van Tine.

ADVANCEMENTS INCREASE EFFICIENCY Skilled, experienced operators have become more difficult to find. “However, with the latest advancements in wheel loader technology and proper training on features and settings, contractors can get the most out of their operators and machines to maximize loading efficiency,” says Van Tine.

Many manufacturers include productivity-enhancing features such as return-to-dig and adjustable loader kickout height adjustments. “Use the functions on the machine designed to improve cycle times — that’s why they are there,” says Connolly. “Two good examples include bucket and boom kickout and return-to-dig. The boom

on the same equipment in the same application.”

Some loading techniques have proven more effective than others. “Practice loading the bucket by engaging material at the bottom and then slowly and effectively curling the bucket and lifting the boom arms simultaneously until you have reached the top of the pile,” Rogers advises.

“This method is much more efficient than working the machine into the bottom of stockpiled material to load the bucket.

Trying to operate this way will only burn more fuel, be potentially damaging to the working equipment (buckets, pins, boom arms, cylinders, etc.), and increase potential for wheel spin and consequently tire wear.”

Operator technique when entering the pile has a huge impact on not only loading efficiency, but also operating costs.

“Operators should limit tire spin in loose materials to prevent premature tire wear,” says Van Tine.

“This is a common hurdle that less experienced operators must overcome.” Features like spin control limit tire spin in loose conditions when crowding a pile.

“Differential lock can be used when additional tractive effort is needed to provide full power to the wheel with traction.”

Rimpull control is another useful feature that allows the operator to adjust the power being sent to the wheels to compensate for ground conditions.

“This reduces wheel spin and slippage, thereby reducing tire wear and improving productivity while lowering total cost of ownership,” says Connolly.

Volvo offers several technologies that can ease the effort required to load. “The first is adjustable lever sensitivity, which allows the operator to choose the response level of the hydraulic levers to suit their operating style,” says Connolly. Volvo wheel loaders have three response modes: soft, active and normal.

Soft is meant for a slower or more precise task; active works for fast-response, demanding productivity requirements; and normal is in between.

“Operator technique is critical when entering the pile, but please realize this is not where one single technology

WHE E L LO A D E R S Ensuring the loader is properly sized for the application and equipped with the appropriate bucket, ground-engaging tools and tires is an important first step for optimizing loading efficiency.

Caterpillar’s M-Series mid-size wheel loaders include a color touchscreen display, which helps operators monitor critical machine systems and also query for any button or function on the machine, including how it works and its settings.

kickout is especially helpful if the operator is loading a truck at the same height for an extended period. On Volvo wheel loaders, the automatic boom kickout position can be set to any position between maximum reach and full lifting height, and it can be done with one stroke of the lever rather than having to hold the lever. The return-to-dig function allows the operator to set a position to which the boom will lower prior to filling the bucket at the pile.”

Liebherr wheel loaders include bucket leveling and return-to-dig. “These features provide quick and easy inputs from the operators to get the working equipment back into the position to engage material for loading,” notes Rogers.

“These functions automate processes that would otherwise be performed manually, providing precision and efficiency.”

Operator assistance systems are being developed by manufacturers to help operators improve their loading methods. “I believe these features will continue to be developed and enhanced so that operators (novice or experienced) can increase their performance on the job,” says Rogers. At CONEXPO-CON/AGG 2020,

Liebherr displayed multiple solutions for safety and efficiency.

For example, an adaptive lighting system helps to reduce glare and distraction and increase visibility for the operator when the machine is in the loading and unloading cycles.

Joystick steering is another development that can add productivity. “Configuring a machine with and using joystick steering can be key in a production-focused application,” says Schmidtgall. “Operators sit in

the cab like a statue and have extended their careers past planned retirement age or have eliminated chronic neck and back pain from using conventional steering systems. Cat joystick steering is designed with safety and redundancies which eliminate the need for a steering wheel in the cab, opening up leg room and forward visibility to further aid comfort and safety, ultimately enhancing productivity.

“Caterpillar also offers auto-dig as an option,” he continues. This feature allows the machine to control most of the dig cycle, which can be very helpful to novice operators. “In addition to controlling the dig cycle, the system also optimizes engine rpm and torque, which results in fuel savings for the machine.”

Manufacturers, including Caterpillar, have also introduced collision avoidance technologies.

Radar detect technology provides an audible and visual alarm when the machine is backing up and approaching an object. “The color touchscreen display shows colored bars to indicate distance remaining,” says Schmidtgall.

“The radar is speed-sensitive, meaning that if the machine is backing up too fast, the alarm will sound sooner to allow for operator reaction time. This feature can help avoid damages to machine or property and helps operators of all expertise be more confident, and therefore productive.”

Caterpillar offers an intelligent Eco mode, as well, that maintains 1st gear rimpull and torque to load the bucket quickly while digging in the pile. “It simply clips out maximum acceleration in travel gears to save fuel,” says Schmidtgall.

“An operator in a truck loading application would see no affect to his cycle time and realize a potential 7% fuel savings."

John Deere

Most manufacturers have integrated touchscreen displays in their current wheel loaders. Since Caterpillar’s M-Series introduction, its midsize loaders have included a color touchscreen display that helps operators monitor critical machine systems and also query for any button or function on the machine (how it works and its settings). “The proof this system works is that it’s so intuitive that Caterpillar never had to provide specific training, but just allows operators to familiarize themselves with it and they learn quickly," says Schmidtgall.

INCREASE EFFICIENCY WITH ONBOARD SCALES Scale systems reduce the guesswork. “Having a system that can provide feedback about how much payload a machine is carrying in the bucket will help the operator load trucks faster and will reduce the possibility of overloading or under-loading trucks,” says Rogers.

Onboard weighing systems improve efficiency by providing real-time material weight to the operator. “This can significantly reduce both machine and truck overloading, which decreases wear on both units and avoids costly issues such as overweight fines and partial dumping,” says Connolly. “The data that the [Volvo] scales provide can also be viewed remotely through the use of a cellular data connection or by push download directly from [Volvo] Co-Pilot.”

Onboard weighing systems, such as Volvo Load Assist, can improve efficiency by providing real-time material weight to the loader operator.

“The John Deere Payload Weighing System features dynamic weighing, facilitates more accurate loading and allows material movements to be tracked,” says Van Tine. “It is fully integrated with JDLink telematics, enabling customers to track and visualize payload data in the JDLink portal and JDLink Mobile.”

Caterpillar offers the Caterpillar Production Measurement (CPM) payload scale feature. “This on-the-go payload system builds an operator’s confidence in what he is doing and provides him the information he needs at the time he needs it to do his job more accurately, faster and within acceptable parameters,” says Schmidtgall. “CPM has a unique feature that allows the operator to use a low-level tip-off, a resource that allows operators to use an estimated weight and tip-off material in an efficient fuel- and time-saving manner vs. a traditional scale.”

The Liebherr integrated weighing system with Truck Payload Assist is an optional system that provides on-the-fly information about the payload in the bucket and also allows for the operator to set payload targets for loading trucks.

“Once the target weight is set, the operators can begin loading the bucket and the assistance system will count down how much material is left to hit the target weight,” says Rogers.

“All of this information can be viewed via the integrated touchscreen display.” ET

34 EQU IPM ENT T OD AY | April 2020 ET0420_34-36_PowerSources_CB.indd 34

for 2020, including a glimpse at what may lie ahead.

CUMMINS TAKES ADVANTAGE OF INTERNAL RESOURCES Cummins Inc. produces over a million gensets annually for a variety of markets ranging from the military to recreational vehicles (RVs). Given this broad market reach, the company’s mobile products group saw an opportunity to capitalize on its success in other areas, leading to the introduction of a 12-kW mobile generator set, the C12D6RE, with a Tier 4 Final-certified, four-cycle, liquid-cooled diesel engine derived from the RV industry.

The idea for the C12D6RE actually came from key rental customers who suggested Cummins take the 12-kW generator used in the RV industry and apply it to mobile generators. But to be successful, this required a revamp to meet more rigorous customer demands.

“The new C12D6RE model is equipped with several features and options making it a very reliable, flexible and robust product, ideal for mobile power applications,” says John Gibbons, North American general manager, generators, Cummins Mobile Power. Shedding its recreational roots, it now boasts a rugged and robust design and a heavy-duty trailer suited for events, construction sites and industrial use.

Cummins continues to explore new options for more efficient power generation, including incorporating smart paralleling logic into its Tier 4 Final products that turns units in parallel on and off based on demand. The result is not only lower fuel consumption

but reduced maintenance requirements per power source.

Given recent acquisitions of energy storage and management and fuel cell battery technology providers, as well as partnerships for other alternative power technology, rest assured that Cummins has its fingers in more power possibilities.

“In growing itself and looking toward the future, we still will continue to maintain our No. 1 [global] status as a diesel engine manufacturer,” says Gibbons.

“But we’re also looking at additional technologies, whether it be for power generation or whether it be for on-highway or off-highway.”

DOOSAN DELIVERS WET STACKING SOLUTION Over roughly the past 18 months, Doosan Portable Power has focused specifically on adding value for its customers — for example, in the form of power density improvements in larger diesel products along with enhanced aftertreatment systems. Its entire portfolio also includes improved controller interfaces, extended maintenance intervals, longer filter life and more.

Recently, the company added its proprietary Doosan engines and airends to the smaller segment of its product line, including the P185WDO portable air compressor (www.ForConstructionPros.

com/12041282). The next step was to tackle the troublesome issue of wet stacking in Tier 4-compliant generators used in light load and fluctuating demand applications.

Wet stacking largely stems from mis-education, says Craig Wilkens, business development, Doosan Portable Power, with customers often renting larger generators than they actually need. The result is the generator does not reach sufficient operating temperature to completely burn off all of the fuel, resulting in carbon buildup and plugging of exhaust components.

To mitigate this issue, the company developed the internally packaged Intelligent Load Management System (ILMS) option. The ILMS option automatically adjusts engine and exhaust temperature with supplemental heat to ensure the generator operates at full capacity regardless of load demands.

The Generac VTS solar-powered light tower will be available by the end of this year.

POWR2 is answering the need for higher capacity energy storage systems with the addition of 480V models with 125- or 250-kVA power output and up to 1 MW hours of energy. when needed, meaning when you’re below 30% load.”

In applications with fluctuating power demands, the system can instantly respond to ensure full generator capacity is always available even in the event of a sudden heavy load, such as motor starting.

The ILMS is compatible with any voltage output produced by the generator, meeting the needs of a variety of applications with no special setup or switching required. The option is offered across the company’s small- to mid-size generator lineup and select large generator models.

GENERAC ADVANCES TOWARD HYBRIDS AND SOLAR POWER Durability and serviceability are essential in power generation, which is why Generac Mobile Products redesigned its MDG25 with this in mind (www.ForConstructionPros. com/21123041). The enhanced

version provides reliable three-phase 25-kVA power in a compact, easily towable footprint and is suited for the rigors of the work site.

“In this design, we have a steel, square-bodied construction that allows for rugged durability in all the different applications,” says Matt Wiese, senior product manager – generators. “We also have the ability to remove the doors for clear maintenance within the engine and the whole system.”

A wet stacking mitigation kit consists of an LHD liquid heat generator. “It allows us to provide a solution for wet stacking problems when the load reaches a level that’s below 30%,” Wiese explains. “The system will kick on and increase the load… That helps with certification and with the longevity of the engine.”

In addition, the MDG25 has a simplified controller platform with fewer buttons and an easy to read status screen for easier operation (www.ForConstructionPros. com/21072260). Its larger fuel tank enables 28 hours of run time.

Extended oil change intervals enable 500 hours between services.

Generac is exploring alternative power options, too, particularly in its light tower line. At the ARA show, it highlighted the VT-Hybrid light tower and the VTS solar light

tower, both of which are currently available in Europe and will be launched in North America in late 2020/early 2021.

The VT-Hybrid comes with 4x150W high-efficiency LED floodlights powered by a rechargeable battery pack that provides up to eight hours of continuous operation with no diesel or noise emissions.

“This system is very useful if the customer has to use the [light tower] indoors or in a tunnel,” says Giovanni Paulo Licheri, product manager, Generac Mobile Products in Italy. “It has a simplified control panel that can operate in manual mode or timer mode with fourand eight-hour autonomy.”

The special dry batteries can be recharged in less than five hours from an external power source or from the built-in backup generator. The generator’s diesel engine will automatically start once the battery pack is discharged to continue powering the lights while simultaneously recharging the battery pack.

Once fully charged, the engine will automatically turn off.

Powered by three solar panels, the VTS light tower combines a solar charge controller and an inverter/charger in one product. Its four AGM batteries are charged by the three 320-watt solar panels and/or through the inverter from the utility grid or an external power source. The batteries recharge in approximately six hours and can run the lights for roughly 16 hours.

“The strength of having a broad product line is that instead of offering one solution for an entire market, you can offer really specific solutions that meet the needs of the different market segments that we operate in,” says Thomas Rugg, president, Allmand Equipment.

This includes introducing new engine- and batterypowered products thanks in part to collaboration with sister company Vanguard.

At the ARA show, Allmand showcased a Vanguard gasoline-powered light tower, the GR chain series light towers with a new air-cooled diesel engine option, plus three concept fully electric models: two inverter generators and a 10-kWh light tower, all powered by Vanguard lithium ion batteries. (Learn more at www.ForConstructionPros. com/21115407.)

The inverters feature 5- and 10-kWh Vanguard commercial lithium ion battery packs and include one 120V TT-30P and two 120V duplex receptacles.

THE ADVANTAGES OF BATTERY POWER INCLUDE ZERO EMISSIONS AND QUIET OPERATION.

A detachable inverter module allows a quick swap between battery packs. A touchscreen display gives users information on power level, run time, status indication and necessary product feedback.

Other features include onboard lighting, enclosed accessory storage and powered tracks for ease of transport.

“There are many gasoline and diesel-powered inverters on the market,” says Becky Fellows, marketing manager.

The advantages of battery power include zero emissions and quiet operation. “It’s silent — you’re not running an engine. And it’s clean technology.”

The concept light tower on display was equipped with four LED 350W light modules for commercial grade light output, a five-section mast that expands to 22+ ft. and 359˚ rotation. Built upon the Night-Lite E Series platform, the unit includes the same touchscreen data display as the inverters, as well as forklift pockets, an active leveling system and auto deploy outriggers with one-button product setup.

While commercial availability may be a few years away, these concepts offer the opportunity to initiate discussions that can drive new solutions in future.

“We’re showcasing concept units at ARA to gain customer feedback to understand the applications for battery-powered equipment,” Fellows comments, adding. “From the standpoint of performance… Vanguard has done extensive research and the application of these products has been keeping up with gasoline and diesel engines across the board. So, it’s really just a different mindset of how to power rather than performance.”

Designed. Engineered. Remarkable Value.

POWR2 started production of its hybrid power systems for the North American market in late 2018, but soon realized customers were looking for higher-voltage alternatives.

It’s answering this need with an expanded lineup of lithium ion energy storage systems that includes 480V models with 125- or 250-kVA power output and up to 1 MW hours of energy.

The hybrid POWRBANKS

The new Cummins C12D6RE mobile generator boasts a rugged design and a heavyduty trailer suited for construction and industrial applications.

The 12-kW C12D6RE has a Tier 4 Finalcertified, four-cycle, liquid-cooled diesel engine originally derived from the company’s RV business. are designed to integrate with diesel generators and other energy sources to maximize efficiency of power generation and consumption, while reducing noise, emissions and fuel use.

“We work with customers that have large fleets of diesel generators for jobsite power.

When they’re specifying a generator for a jobsite, it’s very difficult to size it correctly because you have to size it based on worst-case scenario,” notes Tim Doling, director – business development. “That leads to generators being oversized, and also the actual load varies throughout the day.”

POWR2 saw the opportunity to place an energy storage system between the generator and the load that would allow the generator to run only when required and be automatically switched off — with power supplied by stored energy — once load demand fell below a specific level. The onboard energy control module constantly monitors load and automatically switches between generator power and stored energy as needed.

“Primarily we’re reducing the hours on the generator. So, rather than run the generator 24 hours a day, we’re probably cutting that run time to four hours a day,” Doling asserts.

“That increases the service life

of the generator. It also increases the resale value. It reduces fuel consumption and emissions.

It’s silent power, which is very important in residential areas or events.”

Less run time at low loads eliminates a critical service issue, as well. “Tier 4 Final generators are very sensitive to wet stacking; they will actually shut down or go into regen,” says Doling. “By making sure they run just when they need to, we can eliminate wet stacking and that service problem.”

Doling sees a trend to move away from generator power altogether with energy storage becoming the primary power source. “Where in the past you’ve had a large generator and a small hybrid unit, we’re seeing a trend toward using larger hybrid energy storage units and pairing them with a small generator just to recharge, or even solar,” he comments.

Systems can be charged from the grid, as well, to convert that energy into more usable power.

“Think of a typical construction site that has 120/240-volt power available, but they have a crane that uses 480 volts. We can use the hybrid [power system] to take that incoming single-phase power and put 480 volts out to the crane,” Doling explains. “It actually eliminates the need for a generator altogether, and that saves you more cost.” ET

10 TIPS TO REDUCE

UNDERCARRIAGE COSTS Slash undercarriage costs through proper acquisition, maintenance and operation.

fer

W

hen operating construction machinery that runs on steel tracks, controlling undercarriage cost is critical to optimize the total cost of ownership. Consider that 45% to 60% of the repair and maintenance costs associated with maintaining a dozer over its life relate to the undercarriage.

By selecting the most appropriate undercarriage, following a structured maintenance plan and training operators, you may dramatically lower system costs and thus lower equipment owning and operating costs. There are controllable and non-controllable variables that determine

 Wider shoes put added stress on undercarriage chain. It is advisable to use the narrowest shoe that works in a given application.

undercarriage life. Not much can be done about the application or underfoot conditions, but the operator’s behavior and the correct machine setup play a major role in cost control.

The best place to start is with proper component selection.

TIP 1: S ELECT THE CORRECT SHOE WIDTH

Choose the proper shoe width by considering the weight of the machine and the application. For instance, narrow shoes have better soil penetration and grip. Wide shoes typically work well in soft underfoot conditions because they have more flotation with lower ground pressure.

Proper shoe width is directly correlated with the machine weight and wheelbase. The wheelbase defines how many shoes are in contact with the terrain. The machine weight with the required attachments defines the ground pressure.

For hard and abrasive material, use narrow shoes; for soft ground such as clay, use wider shoes. For swamps or peat, an LGP (low ground pressure) undercarriage with extreme wide shoes is necessary.

Most undercarriage experts advise using the narrowest shoe possible. The wider the shoe, the harder it is going to be on the undercarriage structurally. Shoes that are too narrow can create their own problems. They allow the machine to sink. It is harder on the powertrain, which results in higher fuel consumption. It will also bring more material into the undercarriage during turns, which reduces undercarriage wear life.

Determine the narrowest shoe that will support the machine’s weight above ground. Go wider only when absolutely necessary.

www.ForConstructionPros.com

ET0420_39-41_Grading_Undercarriage_CB.indd 39

TIP 2: C HOOSE THE RIGHT GROUSERS

Consider the application before choosing the type and number of grousers per shoe. A single or double grouser may work well when laying pipe, but may not work well in other applications.

Typically, the higher number of grousers the track has, the more contact the track has with the ground. Vibration is reduced and the track will last longer when working in more abrasive conditions.

TIP 3: P ICK THE CORRECT SHOE TYPE

Mid-size dozers offer a dizzying array of shoe types. The number of choices allows the machine to be best matched with the underfoot conditions.

Moderate service (MS) shoes are recommended for use in soft and non-abrasive material. In more abrasive conditions, extreme service (ES) shoes are typically the more cost-effective choice.

The ES shoe helps you from a structural standpoint. It will resist breaking because of the plate thickness. It has a taller

With the grouser being taller and wider, it is harder to get into the ground, so you could suffer penetration problems.

ES shoes also add significant weight to the machine, which could affect flotation.

The grouser works like a blade on the soil, so the thinner the grouser shape, the easier the ground penetration, which results in a smoother ride. ES shoes are not recommended in applications where a smooth ride is key or where the soil provides very high impacts to the undercarriage.

ES shoes are suitable for rock, shotrock applications or pioneering dozers (with oscillating track frame). These shoes are

G R AD I N G /S I T E P R E P

hard on the chain joints, so use them sparingly. Most larger dozers use severe-service shoes, but smaller machines do not benefit from their use, since they add cost and affect smoothness of travel. Severe service shoes affect grading performance, since they can create vibrations that can be transferred to the blade.

Many shoes have options such as trap holes to get material to flow out of the link box. Trap hole shoes are recommended when you are in conditions such as tacky mud that would likely cause a tight track incident. The sprockets will eject the mud out of the link box and ensure you maintain proper track tension.

In other applications, a trap hole shoe can prove detrimental. The shoe is there for flotation. If you punch a hole in the middle of it and it is in soft underfoot conditions, all of that material will eject up through that hole and come right into that link assembly, which can reduce wear life.

Clipped corner shoes are often used for fine grading.

The clipped corner gives you less ground disturbance when you are making turns. It allows the tractor to turn more easily.

Clipped corners on wide shoes prevent the shoe from bending

A tight track can substantially increase wear on the idlers, links, bushings and sprockets.

too much and reduce the risk of links breaking.

There is not one shoe that will work in all applications.

The choice will depending upon your geography, climate and soil condition.

TIP 4: S ELECT THE PROPER CHAIN DESIGN

Lubricated chains are indicated for machines that are constantly moving because the oil is able to create a constant film between the pin and bushing. Sealed and lubricated track (SALT) is required for most applications. It reduces the internal friction in the undercarriage by providing internal oil lubrication, resulting in a long life. This system can be used in almost any application, except in high heat, such as hot slag applications.

Of course, there are still applications for dry track. Dry track is stronger against torsional stress and twisting types of movement. But internal pin and bushing wear will become the No. 1 reason for service work, replacing external bushing wear.

Rotating bushing designs are another means to extend component life. Rotating bushings reduce or eliminate internal pin and bushing wear. Fewer service intervals equal more uptime and less cost per hour.

Rotating bushing tracks take the sliding component out of the wear equation. Therefore, this type of track is much more tolerant of reverse operation. Wear rates are almost nothing, even in high-speed reverse. The rotating bushing is crawling on the sprocket, allowing it to always maintain a round shape whether the operator drives forward or backward.

In the past with conventional

 Selecting the most appropriate undercarriage, following a structured maintenance plan and training operators may dramatically lower undercarriage costs and thus your owning and operating costs, plus prevent unplanned downtime.

undercarriages, the bushing would be worn at a much higher rate due to “scuffing” wear around the sprocket. With the onset of rotating bushing undercarriages, this bushing scuff wear is basically eliminated.

Rotating bushing designs do not require the machine to be taken out of service to have a technician turn or rotate the pins and bushings. The design goal is to balance the wear of the undercarriage components so they wear out at about the same time.

Not all applications are suited for a rotating bushing track design. Avoid these systems in applications with heavy impact shock loads (rocks and stones), especially when ripping. These impact loads tend to crack and break the rotating bushing portion of the track system, which results in costly track repairs and replacement.

TIP 5: M AINTAIN PROPER TRACK TENSION

Tight track is the No. 1 cause of premature track wear on a dozer undercarriage. When you change applications, run the machine for an hour on the new site and then set the track tension to the correct specification. Re-check the tension as conditions change.

For instance, if it rains overnight or during work hours, that will change the amount of packing and track tension will need to be readjusted.

A tight track can substantially increase wear on the idlers, links, bushings and sprockets. Tight track can also damage the sealing system due to high track joint temperatures. It is always better to run a bit on the loose side so that if packing increases, there is some margin of error before damage/increased wear begins.

Tight track will also rob useful horsepower and increase fuel consumption.

Conversely, when a track is too loose, it can start to drag on the top of the roller frame. It can also result in derailing, chain popping out from the sprocket, unusual impacts between parts and possible chipping and spalling.

The perfect balance between tight and loose stays within the sag recommended by the manufacturer. This requires regular attention. During the life of the undercarriage, normal wear on parts will naturally allow the tracks to become loose.

TIP 6: K EEP IT CLEAN

At the end of each workday, operators should take time to clean out dirt and other debris that may build up in the undercarriage. Shovels and pressure washers can be used to help the cleaning process.

A packed track will rob horsepower to the ground and will reduce undercarriage life due to heat and additional stresses. This is especially true in colder climates where mud, dirt and debris will freeze.

The biggest issue when you do not clean out the undercarriage is that the material dries/ hardens or continues to fill the space between the frame and track. The links eventually start to drag across it. This adds an additional contact point for the links and results in higher wear rates.

Mud packing over time creates extra layers of material on the undercarriage parts, overtensioning the track group association and increasing the

TIP 10: PAY ATTENTION TO

MACHINE ORIENTATION

wear. Sometimes, hard materials like rocks or concrete getting stuck between the roller shells and the rock guards can lock up the rollers, creating wear flat spots on these components.

TIP 7: C ONDUCT ROUTINE INSPECTIONS

Complete a full undercarriage inspection to look for excessive or uneven wear as well as damaged or missing components. If the machine is being used in harsh applications or other challenging conditions, the undercarriage may need to be inspected more frequently.

The following items should be inspected on a routine basis: ˜ Drive motor ˜ Drive sprockets ˜ Main idlers and rollers ˜ Rock guards ˜ Track bolts ˜ Track chains ˜ Track shoes ˜ Track tension Inspect the rollers, idlers and drives for oil leakage. Oil leaks could indicate a failed seal, which could lead to a major failure in the rollers, idlers or track drive motors.

TIP 8: U NDERSTAND

WEAR LIMITS

Eventually, chains, sprockets and idlers need to be replaced.

Change them out as a set if possible. If you put used rollers on new links, it will reduce the overall life of the link; the same goes for used segments on a new bushing. The issue with this is that the new component and the old component are going to work against each other until their shape matches up again, which results in higher wear rates.

Undercarriage life is driven by wear. You want to run the maximum life of the undercarriage without exceeding it. Once the wear of the link achieves the maximum, the link pin boss may get stuck against the roller flange, even if the roller shell is worn out at its own max. The pin and bushing may start popping out from the worn sprocket. The track adjuster may reach the end of its stroke and not be able to keep the tension on the system anymore, causing the tracks to derail. Any of these factors can cause serious damage and even safety-related issues.

TIP 9: U NDERSTAND EFFECTS OF CONTROL MOVEMENTS

Modern hydrostatic machines allow operators to turn fast and on a small radius.

This creates additional stress on the undercarriage as the track

group assembly is subjected to additional pulling forces coming from the final drive. Those extra efforts tighten the track group assembly and increase the wear rate.

This is where operator skill makes a big difference. Sharp turns and counter rotations increase contact stresses between components and should be minimized. These maneuvers apply high stress to the tracks by braking one side or the other. If these maneuvers are done more slowly, it does a lot less harm to the undercarriage. As speed increases, the amount of damage increases. A good track inspection will pick up indications that the machine is not being operated correctly.

High-speed reverse should also be avoided. On fixed bushing track, the bushing and sprockets will see increased wear rates while running in reverse.

During reverse operation, there is sliding wear between the bushing and a sprocket at any speed. But as the speed increases, the amount of load and contact changes, increasing wear rates. Speed also tends to move the bushing out of the root of the sprocket to a point higher on the sprocket tooth, which also changes the contact pattern and results in higher wear.

 Complete a full undercarriage inspection to look for excessive or uneven wear as well as damaged or missing components.

Side hill operation accelerates undercarriage wear, especially on the downhill side of the machine.

The link side is working constantly against the roller flanges, creating accelerated wear on the links and roller flange. The links and rollers on the downhill side will see higher than normal loads and an increased wear rate, whereas operating on flat ground usually wears the undercarriage mostly on the rail surfaces of both the links and rollers.

Operating on side hills wears off the flanks of the links, which reduces overall link width and the available contact area with the rollers. This leads to increased contact stress when the machine operates on flat ground.

It is important for the operator to balance machine orientation as evenly as possible.

CASE DL550B Compact Dozer/Loader Initially introduced at CONEXPOCON/AGG 2017 as “Project Minotaur”, the production version DL550B leverages the footprint of a compact track loader (CTL) with the chassis-integrated C-frame and blade of a dozer to create a powerful two-in-one machine for grading and loading applications. It features a true dozer-style undercarriage for optimal dozing performance and is available in steel or rubber track configurations. The roughly 18,000-lb., 114-hp unit features a six-way blade and its C-frame attaches directly into the chassis and primary coupler of the machine. This design provides the stability and smooth operating plane of a small dozer and ensures all operating power and stress is channeled through the chassis instead of the attachment coupler and arms. To transition to CTL-style operation, the operator simply hydraulically detaches the C-frame and blade to match up with a bucket, forks or other skid-steer and compact track loader attachments. Major changes compared to the original concept include an evolution from radial to a vertical lift geometry and an increase in rated operating capacity from 4,500 up to 5,500 lbs. (50% tipping load).

TECHNOLOGY TRENDS

T

here are estimates that 4.6 million telematics systems will be active in the construction industry by 2021.

Given the rapid implementation by construction equipment suppliers, this figure shouldn’t be too surprising.

“If you look at the construction industry and the

DATA

s

manufacturers of the equipment, virtually all of them are embedding some type of telematics device in their equipment today,” says Todd Brockdorf, Otonomo’s Head of North America’s Solution Architecture. Otonomo is a connected vehicle data services platform that works with OEMs and fleet providers to filter and disseminate data to those who develop apps and services for vehicle and equipment owners.

“The rise of telematics is making connected vehicle technology more accessible, and there are folks out there that are building services around those connected vehicle technologies,” says Brockdorf. “[Otonomo is taking] connected vehicle data, ingesting that into our platform, normalizing it, aggregating it, securing it and then providing it to folks that are building innovative applications and services around connected vehicle technology.

“The benefit… to the owners and operators of the equipment is we can bring them innovative app and service providers to help enable their operations to become more effective,” he adds.

CURRENT BENEFITS OF TELEMATICS Telematics has already revolutionized construction operations.

“Benefits to the owners of the equipment include things like location data… especially when you have owners that aren’t out in the field, or renters of the equipment providing it to other companies to use for a jobsite,” says Brockdorf.

This data aids in areas such as

logistics management and equipment recovery. “The industry as a whole is trying to address a $400 million problem of equipment theft,” Brockdorf states.

“Understanding the position of the equipment — if it is still on a jobsite, if it is moving on a trailer off of a jobsite unauthorized — these are the kinds of things that they’re using the telematics data to address… Loss prevention is one of the big areas in which they’re using telematics data.”

Another common application is determining how long and in what manner equipment is being used on a daily basis. “That’s probably the biggest use of telematics data in the construction industry,” says Brockdorf.

Then there’s the ability to perform predictive maintenance.

“For fleet operators, understanding their machines’ performance and predicting failures and when they need to maintain their machines is another key use case [for telematics],” says Brockdorf.

“If their equipment isn’t up and operating, that affects the company’s performance and their ability to deliver on their commitments to their customers.

“Understanding the state of their machines, understanding critical maintenance — when it might need additional service or when to schedule service for that machine such that it doesn’t conflict with a job — predictive maintenance is another key area for this data,” he asserts.

TELEMATICS MOVES INTO ACCIDENT RECONSTRUCTION Yet, telematics providers are just scratching the surface when it comes to potential construction applications.

“There are literally hundreds of parameters that can come off of these machines,” says Brockdorf. “And that’s where you get into more sophisticated and interesting use cases.”

For example, one intriguing potential use for telematics data is in accident reconstruction.

“Accidents in the construction industry are costly for the insurers of the equipment as well as companies that are involved in them,” Brockdorf comments.

“Insurers are looking for ways to reduce costs related to accidents, and the [construction] companies themselves are looking to increase safety. Telematics and

the data that comes off of the machines are able to help address both of these concerns.”

Telematics data could be used to identify the exact location of the various equipment on a construction site and what it was doing when an accident occurred.

“If it’s a skid loader, for example, you can see the position of the bucket and how that might affect the accident. You can look at things like the safety bar use, and if proper safety precautions were being taken by the operator of that machine,” Brockdorf explains. “So, all of these different parameters, and more, can become data points within an accident scene for reconstructing accidents, both to the benefit of the insurer [and] the company in helping to increase safety and reduce accidents to begin with.”

Currently, this application of telematics data is in the exploration phase. “[Insurers] are examining this as a new way to understand accident scenes,” says Brockdorf. “So, we’re just on the cusp of using this type of information in insurance use cases and accident reconstruction.

Right now, it’s used in modeling so far, but it is quickly becoming part of their ability to investigate insurance claims.”

“SHARED CUSTODY” OF YOUR DATA External use of telematics data is still a relatively new field in the construction industry.

“Equipment manufacturers have been placing telematics devices in their equipment and have been collecting this data in the last few years or so,” says Brockdorf.

Now, they’re trying to figure out how to “operationalize” it outside of their own operation.

“They’ve been using it for a few years now in their own internal use cases. But exposing this data externally to organizations like insurance providers — that’s a relatively new endeavor for them,” Brockdorf indicates.

“That said, there are commercial insurance folks that are looking at figuring out how they can use this data to do things like accident reconstruction and ratings of policies for fleets and fleet operators. So, it’s a new field, but it’s a very promising field.”

Insurers and other service providers won’t be given indiscriminate access to your information, Brockdorf assures.

www.ForConstructionPros.com

ET0420_44-45_TechTrends_Telematics_BC.indd 45

Fleet owners would, in most cases, have to provide explicit consent up front, say, as part of establishing the rating for a commercial policy. Only then would the insurer be able to use the data in accident reconstruction.

“They would already have this information as opposed to [trying to] obtain the data after the fact,” says Brockdorf. “There is a clear chain of consent and openness and willingness to share the data from the machine… then that would be part of the insurance chain of events and chain of custody for the data.”

COST AND TIME SAVINGS You may ask what the incentive could possibly be to share your data with anyone, let alone your insurance carrier. But Brockdorf believes data sharing can open up potential savings.

“The [fleet] owner or operator might be able to get a discount on their commercial fleet if they are willing to share the telematics data that’s coming off of their machines with their insurance carrier,” he points out.

Equipment service is another example. Consider jobsite fueling services.

“Larger jobsites might already have onsite fueling capability. But to keep machines running for smaller jobsites, somebody has to go get fuel for the machines,” Brockdorf comments.

“With telematics data, a fueling service can understand the fuel levels of the machines that are operating on the jobsite, where those machines are located… and then be able to deliver fuel at the site when it’s needed, keeping those machines running and that contractor doing his job instead of [paying somebody] to go buy fuel.”

No doubt questions will emerge surrounding data access, ownership and security as these and other applications for telematics data are developed.

Yet, as with the adoption of other high-tech tools such as mobile devices, online banking and cloud computing, the advantages and convenience offered may quickly outstrip initial industry concerns, opening the door to even further developments. ET

COMPACT GPR SCANS CONCRETE

IN TIGHT SPOTS Cobra Cutting Services is seeing enhanced efficiency from a portable all-in-one GPR system.

D

an Foley is president of Cobra Cutting Services, a full service concrete sawing and drilling contractor, and Rory Foley is his head ground penetrating radar (GPR) technician. The Chicago area company’s GPR scanning division tends to focus on tough jobs where its attention to safety makes it stand out in the marketplace.

The company works primarily with hospitals, wastewater treatment plants and heavy industrial plants, along with institutional facilities like higher education, government and the courts. The Foleys point to the adaptability of the new equipment as a key benefit.

“The portability of the GSSI StructureScan Mini XT works well for the situation,” says Rory.

“It can fit in tight spots, especially those with low clearance.

That makes it good for overhead scanning and where pipes are attached to a wall.”

ADVANTAGES OF ATTACHMENTS The switch from larger GPR units to the portable all-in-one GPR concrete inspection system has proven a great time saver, especially for areas where space is confined and for large trench inspection projects.

Cobra Cutting Services is also using a miniaturized GPR antenna attachment, the Palm XT, which is especially good for

smaller roof sections. “If I’m in a tight spot, maybe only the antenna fits in, or if there’s a little clearance area, I can take the handle off — where most of the larger GPR units wouldn’t fit,” Rory says.

If his team runs into pipes that are tight into the wall, or areas that have smaller leadup, it can use the miniaturized antenna attachment to scan the area, spending less time on the site, and completing a task that might not be possible with full-sized antennas. The handheld attachment can be used in cross-polarization mode, a method that highlights non-metallic objects such as PVC, and deemphasizes metallic objects like rebar and wire mesh.

The cross-polarization mode has had a very positive effect on Cobra’s business. The company had previously stayed away from plumbing or electrical trench inspections with the previous generation of handheld scanners because they didn’t have the ability to cross polarize the antenna.

“Now that we can cross polarize the Palm XT antenna, we can interpret data more accurately and distinguish a target from the conduit,” says Rory.

Another advance is the pole attachment, which Rory uses primarily for scanning trenches.

“If I am going to be scanning trenches, I can throw the pole into the truck, and it means I

don’t have to crawl on the floor while scanning large areas,” he notes. The equipment is more compact and lighter, which makes a difference for jobs where there are hundreds of feet of trench to scan.

Rory also likes the way he can customize how data is portrayed on the screen, making it easier to interpret. He especially values being able to show the gain in many different ways, make color adjustments and change the size of the hyperbola or even view the data in a larger or smaller format.

ON THE JOB SCANS Cobra Cutting Services has used the GPR equipment at a number of high-profile jobsites in Chicago, including Trump Tower and Wrigley Field.

At Trump Tower, the team used a swing stage to provide information needed for drilling holes through the building’s surface to attach the sign to the building without hitting rebar.

Hanging outside of the building with cables about 75 to 100 ft. in the air and scanning the vertical surface was a challenge. The portable GPR unit’s small size and safety strap allowed the team to easily and safely mount the individual letters to the building.

At Wrigley Field, GPR scanning was aimed primarily at identifying any conduit laid in the deck so other renovation

construction would not destroy work that was just installed. Since the job required walking long distances, the unit’s portability was key to the team’s success.

A final example was at a hospital in a southern Chicago suburb, where a construction team was installing a new plumbing trench in a kitchen where 30 conduits were crossing.

The Cobra team used the portable GPR unit with miniaturized antenna attachment to isolate the conduits and ensure plumbers would miss them where they crossed the trench.

 Shown is a GPR scan of a commercial space. Orange marks indicate the location of post-tension cables and reinforcement.

INDUSTRY EDUCATION NEEDED While scanning is becoming more of an industry standard for dealing with concrete slab, more education is needed on its benefits. With the availability of the new technology, the time is right for slab-ongrade inspection to become mandatory, Dan Foley asserts.

“It’s good for safety and loss prevention, and I hope the industry embraces it,” he says. “I believe it should be required on jobsites. I am hopeful it becomes specified because it avoids so many types of damage both to workers and structures.” ET

Paying salaries and insurance benefits — as well as other expenses like uniforms, equipment and vehicles — add up to a large percentage of any company’s revenue. When you look at those numbers, it can be easy to get in the mindset that you’re already spending enough, or even too much, on your employees.

Thinking that way, however, is a disservice to your staff and your company as a whole. You have to view those expenses as the absolute bare minimum, and to avoid problems like high turnover, low motivation and team discord, you have to strive for more than the bare minimum.

To avoid the vicious and expensive cycle of turnover, business owners must prioritize team culture. This can mean different things for different companies, but it has to start with an honest and open conversation about the current culture, including its strengths and areas in need of improvement.

Gathering that information from your staff ’s perspective —perhaps via an anonymous survey — is vital to make any progress. Once you have that knowledge, set aside time to figure out a solution. The conversation should include allocations for the time and resources you’re going to invest to ensure the fixes last long term.

and the Bottom Line

Here are a few steps you can take to invest in your culture:

1

CUSTOMIZE YOUR APPROACH

It would be great if there was a one-size-fits-all solution for team culture that could be replicated in every workplace, but that isn’t the case. Every team is full of different personalities, experiences and working styles.

Have your employees do a survey, sit down with them for one-on-one interviews or set up some combination of the two with a third party so they can talk about the things that are important to them.

For some companies, something as simple as monthly happy hours can go a long way in boosting team morale.

Some team members might prefer being consistently acknowledged for their accomplishments, while others would feel uncomfortable with that kind of recognition. As a leader, it’s your job to understand your staff ’s needs and do whatever you can to meet those needs.

2

KEEP YOUR TEAMS TOGETHER

Whenever possible, build teams and keep them together on projects. In the team-centric construction industry, it’s important for people to get to know each other, become familiar with their communication and working styles and build camaraderie.

By keeping our crew members mostly working on the same teams, productivity increased substantially. No one has to guess who they are working with

or figure out who they should check in with each morning.

Once they clock in, they can just get right to work. This saved my company roughly $50,000 of production costs in the first year.

3

KNOW YOUR EMPLOYEES

It’s important to get to know the individual personalities, preferences and communication styles of your staff. When hiring new people, think through your current teams and where that person would fit in best.

I have personally experienced at least two instances in which placing clashing personalities on separate crews saved four team members from being aggravated enough to quit. It costs my company $2,000 to hire and onboard one new employee, so we saved at least $8,000 by being aware of personalities and adjusting accordingly.

4

REWARD GOOD WORK

Team building and staff appreciation cannot just happen once a year. It has to be a continuous and earnest effort.

Reward employees with bonuses for things like perfect attendance, highlight teams in staff meetings for exceeding expectations or share a portion of the profit when a project is completed under budget.

Everyone needs to feel appreciated for their work. Consistent, tangible rewards will help make sure your employees don’t forget that throughout the year.

It’s safe to assume bonuses and a bump on your employees’ paychecks will be highly motivating, but don’t be afraid to ask

them directly what they would appreciate most.

5

BE HONEST WITH YOUR STAFF

If you’re having a tough year or lost a lot of money on a project, share that with your employees. If you’re excelling or secured a much-needed contract, share that with them, too.

Respecting your staff enough to let them in on how the company is doing will build mutual trust and help them understand why things are being handled a certain way. Transparency is always your best bet.

6 CREATE AN “INNOCENT UNTIL PROVEN GUILTY” ATMOSPHERE In our industry, it seems like we see a lot of the same issues: tardiness and absenteeism, workers taking advantage of tracked time or reimbursements, drug test failures and various other problems. It can be easy to get frustrated and create rigid policies that allow no flexibility or room for error.

Life happens, and people need to know that if they get a flat tire on their way to work or make a mistake on their timesheet, the reaction isn’t going to be unfairly harsh.

Employees who always feel like they’re on trial aren’t going to do their best work, and they definitely won’t feel any affection for their coworkers or company.

It’s important to have systems in place to deal with repeated offenses from the same employee, but be careful not to blame years of dealing with the same problem on someone who may not even be at fault. ET

Conduct Strategic Planning to Survive the Crises

the group can come up with. ˜ Also decide which accounts payables are mandatory payments and stretch them out where you can.

Other vendor payables may require a conversation asking to extend the payment date.

Part of this process is asking banks and finance companies to allow for either interest-only or zero payments for at least three to four months. Use credit cards when you can to spread the payments over a longer term. The cash forecast — using assumptions laid out during the management meeting — should be done within 48 hours. If you do not have the expertise in-house to get this report completed, lay it on your accountant but with the same completion time required.

If the cash forecast says you can make it through four to six months, reassess it daily and adjust as necessary as new information about customers, jobsites and materials come to light.

OVERCOMING A PROJECTED CASH SHORTFALL Should the cash forecast reflect a material shortfall, more planning is required to stop the bleeding with the goal to make it

by material shortages and project cost overruns. Every contract you signed has this language in it. You may find you need to finish Job #1 no matter what since you are responsible for these costs.

OTHER CONSIDERATIONS

out of this six-month financial crisis and move ahead to recover what you have lost. Hopefully, Washington has come up with a plan to provide liquidity to the level where you can avoid the really hard decisions. If not, this is where it gets tough because you are going to have to make hard decisions about employees, vendor contracts and other expenses.

In terms of payroll, you can consider a downward adjustment for a set amount of time, or you can lay off people for a set time frame. If there is the possibility that jobsites may get shut down or projects postponed or cancelled, you may have to lay off personnel. One more option is a straight payroll reduction for all employees that allows for you to keep the talented workers on the payroll. A similar review should be made for job costs, overhead and operating expenses.

Another step is to review your open contracts in terms of your responsibility for delays caused

Other issues to consider include interest rates, deflation, insurance, personnel policies and under-utilized equipment. Ask for an interest rate reduction.

Deflation is real. Make sure you are not overpaying for materials ordered three months ago. Sell off under-utilized equipment to generate cash. Make sure you comply with all federal and state employment issues.

Consider buying locally sourced materials and supplies.

Part of our problem results from goods being made and shipped from overseas, which in many cases can be avoided if they are made in the U.S. Last, consider how this episode is going to change behaviors in the future. For example, I can see working from home changing our business environment because it’s easier to do than people think.

I have a good tech who set up every employee on the system to work remotely. All computers get uploaded to the cloud daily so anyone who needs it has full access to their files. If you can track the work being done, you can control the process. You might give it a shot for those positions where it makes sense.

I hope and pray you all get through the health and financial crises without any major negative setbacks. But the adjustments noted above will be part of that process. ET

Whether it’s the coronavirus pandemic or financial crisis, it’s important to have a plan in place. opefully, by the time you read this the coronavirus epidemic curve is pointing downward. But there is a possibility that it may not be. In any event, all business owners need to plan for a list of “unknowns” to keep their company going (if possible), so that no matter what, you come out the other end with a business still capable of moving forward.

The problem is that we are dealing with issues none of us have ever had to deal with before, and with solutions never before considered — though the financial issues come second when it comes to the safety of your personnel!

So, let’s assume a six-month time frame where our economy and industry are in a state of flux. How are we going to address the unknowns we will face during this time period?

First, get your management team together to develop a “to do” list. This will include your attorney, accountant, CFO and other management members.

Second, management should contact those project owners they are working for to get a status on the jobs and their ability to pay outstanding invoices. This information should be conveyed to the management members.

The major issue is cash flow and cash availability. ˜ Get someone working on a cash forecast. ˜ Take into consideration work-in-progress; billings to be prepared and forwarded to customers; poor-paying customers and any other issues
