Galbreath’s new Work Truck Series Cable Hoists to address light-duty applications

Galbreath recently launched its new WT-1216/X and WT-2018/X work truck series cable hoists. Combining all the toughness and durability Galbreath hoists are known for in a more compact and lighter-weight package, the new models were designed to offer a lighter-duty option to Galbreath’s original 8-inch main frame single axle cable hoist, making them perfect for landscapers, general contractors and private waste haulers who need less power and easier maneuverability.

The WT-1216/X and WT-2018/X can transport loaded containers and equipment up to 20k lbs. and 18 feet in length. With a stout 6-inch main frame, these new hoists feature electric over hydraulic controls using a wireless remote control, making it easier to “spot” containers much more efficiently and safely while monitoring low clearance and maneuvering through difficult-to -reach or tight metropolitan areas.

Engineered and manufactured in the United States with versatility and compatibility with a variety of truck chassis in mind, the new cable hoists are bolt-on ready and easily installed with no welding required, saving time and money. The hoists also come standard with externally mounted secondary manual controls, BOC (back of cab) mounted steel tank w/ dual sight/temp gauge, adjustable bolt-on rear apron and split bumpers and dual 4-inch lift and winch cylinders. The hoists are also tarp system ready, with a mounting platform that is compatible with Pioneer or other tarp brands.

The work truck series hoists are also customizable, with custom engineering layouts to ensure the best fit for each customer, as well as a host of options, including toolboxes, back-up cameras, fenders, expanded light packages, auxiliary front stops and a side-mount oil tank.

“Galbreath is committed to using our unsurpassed hoist knowledge and expertise to solve customer problems through innovations and new product development,” said John Defenbaugh, Wastequip’s commercial president. “Many of the hoists available on the market are simply overkill for many end-users in terms of size and power. By offering a smaller, lighter-duty option, the WT-1216/X and WT-2018/X fill a need and present a compelling product option for previously underserved markets, like landscapers, general contractors and private waste haulers.”

Hydrostatic Trencher can Dig Automatically

Vermeer’s T-755 hydrostatic tracked trencher combines toughness with technology. The powerful machine is designed for digging in rock, cross-country trenching or working drainage and utility projects on roadways. The T-755 cuts trenches as deep as 10 ft and 14- to 36-in. wide at chain speeds of 397 to 724 ft/min. These operations and more are monitored and controlled by Vermeer’s Smarttec electronic control system for versatility and ease of operation. The system also records key functions for proactive maintenance and operator performance analysis. Its software provides real-time operator prompts based on operating conditions.

Vermeer’s T-755 hydrostatic trencher uses a low-speed, high-torque motor fed by two pumps to drive its trenching chain. Although it’s shown here cutting into dirt, it’s just as capable digging into rock using rotary, carbide-tipped cutters.

Traction and Trenching Circuits
The T-755’s dual-path hydrostatic drive, powered by a 275-hp @ 2,200-rpm diesel engine, uses a matching pump, hydraulic motor, and planetary transmission in a separate circuit for each track and is capable of full counter-rotation. A 4-pad pump drive box transmits torque and rotational speed to a pair of pumps that supply the traction and another pair powers the low-speed, high-torque trenching motor. Maximum transport speed for the 37.5-ton machine is 170 ft/min, with digging speeds from 0 to 91 fpm. Practical cutting speed ranges from 400 to 670 fpm, depending on the application and operating conditions. The machine’s service brakes also are hydrostatic, parking and emergency brakes are spring-applied, hydraulically-released.

But the T-755 really gets down to business with its digging chain with rotary, carbide-tipped cutters, which is powered by a single low-speed, high-torque hydraulic motor in a hydrostatic circuit supplied by two variable-displacement pumps through a control manifold. Even though maximum system operating pressure is set at 2,500, the motor can accept intermittent peak pressures as high as 6,000 psi, a condition that is not unusual when digging in rock. Two variable-displacement pumps provide the design flow to the motor; the Smarttec control regulates their displacement in unison. The dual-pump arrangement can deliver full engine power to the chain when needed.

Cat GRADE With 3D Brings Added Utility, Versatility, Operating Efficiency

Yanmar Construction Equipment Europe (CEE) has further expanded its class-leading equipment portfolio with the launch of its ViO82 zero tail swing midi-excavator. Perfectly blending technology and innovation, the new model will be available to order through dealers nationwide from December.

Offering the efficiency and productivity of a large excavator with the space-saving benefits of a much smaller model, the ViO82 delivers unparalleled performance. A true zero tail swing excavator, neither the counterweight or upper frame overhang the unit’s tracks, making the 8,200KG model perfect for operation within tight urban spaces or single carriageways.

Thanks to a robust X-shaped undercarriage design and unique weight distribution, the ViO82 delivers remarkable lifting capability, unmatched stability and torsional stiffness. The boom itself has been specifically designed to swing up to 60° on both sides, in order to maximise operator efficiencies.

Powered by Yanmar’s 3.3L 4TNV98C-WBV1 water-cooled diesel engine, delivering 41.5kW (55.6 HP) gross power at 1,900 RPM, the ViO82 achieves a digging force of 63.5kN (bucket), 25° gradeability and a travel speed of 5 kmph. The addition of Yanmar’s VIPPS21 two-pump independent hydraulic system, which regulates hydraulic flow based on engine speed, minimises pressure loss and improves smooth operation.

A common rail direct injection system allows the engine’s ECU to fine-tune combustion and optimise performance, while cooled exhaust gas recirculation (EGR) technology further reduces exhaust emissions. This, combined with auto-deceleration and eco-mode (which limits power when duty cycles require minimal movement) makes the ViO82 one of Yanmar’s most environmentally-friendly models ever.

The ViO82 further benefits from a comfortable cabin, fully-adjustable air suspension seat as standard and LED lighting. Operator safety has also been prioritised, with a ROPS and FOPS approved design, 360° visibility, large footstep and anti-slip system.

Cat rolls out compact wheel loader

A new Caterpillar compact wheel loader with increased lifting capacity, speed and work tool capability was demonstrated at the company’s year-end press briefing.

“When we talk to our customers, what do they want to do with these products? Well, of course they want to move more material with a given size product, they want to do more with a single machine, and ultimately make more money,” said Joel Grimes, Cat Building Construction Product wheel loader marketing and sales support manager.

“The 903D is well suited to compete for business in a variety of applications – landscaping, snow removal, agriculture, general construction.”

Available with either an open or enclosed cab, the 903D operator’s station features a refined ergonomic design with a new multi-function joystick that provides fingertip control of the standard third-function hydraulic system.

Whether lifting light material into a hopper or loading heavy pallets onto a truck, the choice of standard-lift or high-lift boom arms increase the 903D’s ability to work efficiently in a wide range of applications, with buckets ranging in capacity from 0.8 to 1.3 cubic yards, forks, or a selection of powered and non-powered work tools.

“This little guy can take up 5,400 pounds. What’s a pallet of wet sod weight, what’s a pallet of seed weigh, what’s a big bag weigh? Somewhere in the 3,000 pound range which means this machine can now very comfortably move palletized material,” Grimes said.

“We’ve kept this product under 10,000 pounds in weight, but we boosted its payload by 25 percent (compared to its 903C2 predecessor). We’ve pulled its front axle forward about six inches which means the weight that’s already in the machine is more efficiently being used to move that payload.”

The 903D also features a standard auxiliary (third-function) hydraulic system that delivers a flow of up to 14 gallons per minute at pressures to 3,481 pounds per square inch, producing ample hydraulic horsepower to operate any number of hydraulic work tools such as brooms, power box rakes and grapple buckets.

Cat GRADE With 3D Brings Added Utility, Versatility, Operating Efficiency

The new Cat GRADE with 3D system for D3K2, D4K2 and D5K2 track-type tractors is an automated grade control system using GNSS (Global Navigation Satellite System) technology to precisely position the machine’s blade, without operator input, from first rough cut to finish grade. For added utility, GRADE with 3D incorporates the Cat AccuGrade Ready Option, which allows use of universal-total-station and laser references for automated control.

The new system assists operators of all skill levels achieve specified grades faster and more accurately, compared with conventional methods, while also reducing staking costs and saving rework expense, fuel and machine hours, according to the manufacturer.

Cat GRADE with 3D is an optional system, installed at the factory and integrated into the design of the machine. The GNSS antennas are securely mounted on top of the cab, eliminating the need for mast-mounted antennas on the blade, along with related cables. GNSS receivers and a data radio are also neatly housed in the roof structure. Three inertial measurement units monitor machine orientation, and position-sensing hydraulic cylinders monitor blade position. The integrated installation eliminates the need to remove components at the end of the day.

When in its GNSS mode, GRADE with 3D can provide one-tenth foot-level accuracy by employing real time kinematic positioning technology, which integrates multiple satellite signals with information from an on-site, base-station receiver or other corrections device. The system compares machine location and cutting-edge position relative to an on-board design plan, then automatically positions the blade via an integrated, electro-hydraulic valve module.

The system also delivers this information to the operator via an in-cab display. The system’s 10-inch, color, touchscreen display is incorporated into the dash and provides multiple, configurable views that give the operator a comprehensive view of the site plan and of work in progress. For added convenience, control buttons for activating the system are integrated into the joystick levers.

GRADE with 3D, when activated, automatically controls the movement of the machine’s blade, both lift and tilt, to conform to digital jobsite plans. The only input required of the operator is to steer the machine, reducing overall manual input required by an estimated 80 percent. The new system also is optimized to work with other Caterpillar dozing features, such as AutoCarry, which is designed to assist the operator in attaining optimum blade loads in varying ground conditions, while reducing track slip. GRADE with 3D has the potential to increase productivity by as a much as 50 percent on some projects, according to the manufacturer.

Volvo CE Unveils All-Electric Compact Excavator Prototype

We previously reported on the recent introductions of a refuse truck and mini excavator that both use electric drives to power each vehicle and its hydraulic system. Eliminating the internal-combustion engine from these machines make them quieter and with zero emissions.

Volvo Construction Equipment (Volvo CE) has taken this concept to the next level with its latest concept machine, EX2. The EX2 is a100% electric compact excavator prototype incorporates an electric drive for propulsion, but also for work functions. So, yes, it uses electromechanical actuators and no hydraulics.

The EX2 was presented at the Volvo Group Innovation Summit in London, UK, alongside innovations from across the Volvo Group, including an autonomous refuse truck from Volvo Trucks and an electric bus from Volvo Buses. The innovation summit centered on infrastructure and transport in cities of the future and focused on how the industry can have a positive impact on society through increased transport efficiency, reduced environmental impact and improved traffic safety.

Electrifying Innovation

The Volvo Group defines electromobility as “commercial vehicles and machines that can utilize an electrical motor to propel or to perform the main purpose of the machine.” To make the EX2 prototype fully electric, the internal-combustion engine has been replaced with two lithium ion batteries, totaling 38. kW-hr, which store enough electric energy to operate the machine for eight hours in an intense application, such as digging compact ground.
The hydraulic system has also been replaced with electric drives that incorporate electromechanical linear actuators. Removing the hydraulic system and the gas or diesel engine reduces cooling demand and significantly reduces noise. At this time, the EX2 is purely a research project, and no plans currently exist for production.

Best Practices Move Beyond the Basics

An overwhelming amount of technical documentation presents valuable advice on such topics as the importance of keeping hydraulic fluid clean and why you should change the filters on a regular basis. These basics are second-nature to most hydraulics engineer and technicians. Although basic practices cannot be overlooked, executing best practices can move hydraulic contamination control to the next level.

Fluid cleanliness. Ensure that any fluid is filtered before it goes into the hydraulic reservoir. Fresh hydraulic fluid often is not clean enough to put into a system. So if you can’t verify that the fluid has been filtered to your system’s specifications, run it through a filter before transferring it into the reservoir.

Monitor fluid condition regularly. This means use laboratory-grade analysis on a schedule determined by the operating conditions, not an arbitrary timetable. Always flush a system to manufacturer’s specifications or in line with ISO standards every time components are replaced or repairs performed.

1. A high-pressure filter with visual and electrical indicator is mounted directly downstream of a pump in the hydraulic system’s HPU. The hydraulic system actuates a weir, or gate, in a dam that lets municipal workers control water level in a small lake.

Filter maintenance. Monitor the filters and change them before they go into bypass mode. Again, this requires a schedule based on the operating conditions, not an arbitrary timetable. Make sure replacement filter elements comply with the original manufacturer’s specifications.

Caterpillar introduces new Next Generation 36t excavators

Caterpillar has introduced its new Next Generation 36t size class excavators — the 336 and 336 GC — which are designed to increase operating efficiency, lower fuel and maintenance costs, and improve operator comfort compared to previous models.

According to Cat, the new excavators offer unique combinations of features designed to match contractors’ productivity and cost targets. The new 336 features standard integrated Cat Connect Technology and the most power and lift capacity of the two models for maximum productivity at the lowest cost. The new 336 GC, meanwhile. combines the right balance of productivity features with reduced fuel consumption and maintenance costs for high reliability and low-cost-per-hour performance.

The new 336 has the industry’s highest level of standard factory-equipped technology to boost productivity, says the manufacturer. Integrated Cat Connect Technology increases operating efficiency by up to 45% over traditional grading operations. The standard Cat Grade with 2D system provides guidance for depth, slope, and horizontal distance to grade through the standard touchscreen monitor, making operators more accurate. The system is readily upgradable to Cat Grade with Advanced 2D or Cat Grade with 3D.

Among its several features and smart work aides for operators, the standard Grade Assist automates boom, stick, and bucket movements so operators can stay on grade with single-lever digging. Cat Payload delivers precise load targets and increased loading efficiency with on-the-go weighing and real-time payload estimates without swinging to prevent truck over/underloading. The E-fence feature prevents the excavator from moving outside operator-defined set points—particularly useful when working beneath structures or near traffic.

By design, Cat Next Generation excavators produce more work per unit of fuel than the models they are replacing, says Caterpillar — up to 15% more fuel efficiency for the 336. New Smart mode operation automatically matches engine and hydraulic power to digging conditions, optimising both fuel consumption and performance. Engine speed is automatically lowered when there is no hydraulic demand to further reduce fuel usage. The cooling system features a new fan that runs on demand to keep the excavator working at the correct operating temperature for maximum efficiency.

With a new electrohydraulic system built for responsiveness and efficiency, the Cat 336 and 336 GC feature a new main control valve that eliminates the need for pilot lines, reduces pressure losses, and lowers fuel consumption. Fewer hydraulic lines on the excavators result in less oil required, lowering long-term operating costs.

Compact Excavators Adopt Big Machine Features

For the past decade full-sized excavators have adopted new technologies and features that make them more productive and fuel efficient. Now many of these features and technologies are trickling into the compact excavator market.

“More and more often compact excavators are being tasked to do the job of their larger counterparts, so they are equipped with greater hydraulic flow for improved hydraulic attachment/tool versatility, larger better-equipped cabins and fleet management/telematics to help manage machine location, usage, downtime, etc.,” says Lee Padgett, product manager, Takeuchi-US.

Comfort features from full-size machines are also trickling down into compact excavators. “It was not that long ago that none of the compact excavators had air conditioning,” recalls Tom Connor, product manager, Bobcat. “Now it is a fairly high take rate as far as a factory option.” Cabs have also continued to grow. “When the zero tailswing craze took off 15 years ago, one of the quick ways to help get to zero tailswing was to shrink the cabin space.” In the last five years, creative engineering has gained back space for the operator. “We were able to get about an inch and a half more in width of the cab, which doesn’t sound like a lot, but in a cab that size, it is actually quite noticeable. It allows us to put a wider seat in the machine.”

Bobcat E35Bucket64a320716u5FcBobcat offers several seat choices tailored to customer requirements. “For the R Series, the standard seat is a vinyl suspension seat on an open canopy machine,” says Connor. “But you can option that up to a cab with heat and air that comes with a cloth seat, which is a nice upgrade, especially in the hot weather.” You can even go above that and order a heated cloth seat in the cab-enclosed options.

According to John Comrie, product manager, compact equipment, Volvo Construction Equipment, larger cabs and air conditioning allow operators to focus more on the work with less fatigue, potentially extending the working season. “Many of Volvo’s compact excavators, like the ECR88D short swing model, offer the same features and spacious cabs found on our full-size machines,” he notes. Compact excavators increasingly have not only more cab space and foot room, but also storage. “Operators are often spending an entire day inside these machines. They want to focus on their work with minimal fatigue.”
