Volvo CE R100E rigid haul truck set for Q4 North America launch

Volvo Construction Equipment says it is readying a launch of its 95 t R100E rigid haul truck into the North America market, more than 18 months after customers and dealers at the company’s Motherwell facility in Scotland got a first glance of the machine.

With a size and capacity that make it the largest hauler in the company’s line-up, the R100E rigid hauler promises to drive down operating costs for customers by boosting productivity, uptime and operator comfort, the company said.

It is powered by a 783 kW Tier 4 Final engine, with a combined drivetrain to provide high torque capabilities, “unparalleled pulling performance” and class-leading rimpull for optimum travel times, according to Volvo CE.

Drivetrain control and machine movement are supplied by the new Volvo Dynamic Shift Control, which automatically tailors the transmission shift-points depending on the worksite and operational inputs.

Customers can expect to spend less per haul with the R100E, featuring a 60.4 m3 capacity V-shaped body for optimum load retention and minimal material carry-back.

It said: “The load profile policy enables the operator to meet a consistent average target payload, while the body-tipping system ensures fast cycle times for an all-round efficient performance.”

The Tier 4 Final R100E includes a manually-activated ECO mode for long distance hauls and high-speed applications, meanwhile.

It comes equipped with intelligent monitoring systems such as an On-Board Weighing (OBW) option to ensure the machine moves the maximum safe payload to further optimise production and minimise operational costs. “It does this by using exterior-mounted pressure sensors to monitor and relay machine statistics to the operator’s on-board display,” the company said.

It is also configured with the Volvo CareTrack telematics system to monitor operational data including fuel consumption, machine utilisation and excessive idling reports.

Customers interested in increasing the productivity of existing and future projects have access to Volvo Site Simulation with the help of their local Volvo dealer.

“Site Simulation recommends the most profitable fleet of equipment and project results based on customer needs,” the company says. “By using the simulation, customers and dealers can work together to put an equipment plan in place before a project begins.”

It also has a truck body manufactured from high impact and high abrasion-resistant 400-HBW-hard steel and a ROPS/FOPS-certified operator cab for greater operator productivity and safety. The cab is also fitted onto viscous-type isolation mounts for greater ride quality.

From the operator seat, the operator can observe the job site and surrounding areas through the large glass area and a low rake windscreen. Good visibility is complemented by a 360° surround view system provided by Volvo Smart View. This uses multiple ultra-wide angle exterior-mounted cameras to produce a bird’s-eye-view of the vehicle and surrounding work area via the on-board display.

In addition, the transmission retarder and neutral coast inhibitor secure safe machine control in downhill conditions, while the engine overspeed protection automatically slows the machine down to safe operating limits.

The R100E makes accessing daily service checks and routine maintenance quick and easy with anti-slip steps and secure walkways. All service points are strategically grouped and located within reach from the ground and service platform, while the direct rim-mounted wheel design promotes safe and quick installation and removal, the company said.

The machine features a high degree of filtration for better performance and to prolong component life. “Each functional system on the hydraulics has magnetic suction filters, as well as a pressure filtration on the steering, brake actuation pump and rear brake cooling units,” the company said. “The engine-mounted primary and secondary fuel filters combine with the advanced two stage oil filtration to remove harmful contaminates.”

Volvo will display a Tier 2 version of the R100E at CONEXPO-CON/AGG on March 10-14, with the Tier 4 Final model commercially available in North America in the December quarter of 2020.

Komatsu America launches new WA900-8 wheel loader

Komatsu America Corp has introduced the WA900-8 wheel loader, a 116,400 kg machine equipped with US EPA Tier 4 Final certified emission regulations-compliant engine that is purposebuilt to load 70-150 ton (64-136 t) haul trucks.

Robert Hussey, Product Marketing Manager, Komatsu America Corp, said: “The WA900-8 is the perfect machine for loading haul trucks in limestone pits because the all new Komatsu bucket design, with modified profile, maximises bucket fill to increase productivity. The large pillarless cab offers great visibility, and the higher capacity air suspension seat, along with the Electronically Controlled Suspension System (ECSS), provides a smooth ride for better travel performance to keep operators comfortable throughout long shifts.”

In terms of productivity and efficiency, the WA900-8 has a variable traction control system and modulation clutch system to provide optimal tractive effort for various ground conditions, the company says. Komatsu SmartLoader Logic, meanwhile, helps reduce fuel consumption while maintaining production levels. The wheel loader comes equipped with a closed centre load sensing hydraulic system to deliver hydraulic flow based on application demand, saving fuel and reducing hydraulic oil temperatures, Komatsu says. A throttle lock with auto-deceleration also improves cycle times by maintaining high work-equipment performance.

Under the hood of the WA900-8 is a US EPA Tier 4 Final emission regulation-compliant engine, the SSA12V140E-7, which outputs a net horsepower of 899 hp, or 670 kW (up 5% from the 856 hp on the WA900-3E0). It also boasts dual Komatsu diesel particulate filters/no selective catalytic reduction system and there is no need for diesel exhaust fluid. Variable geometry turbochargers ensure precise engine control and quick response, the company said.

In terms of accessibility and operator comfort, Komatsu listed these traits:

  • Advanced joystick steering system and electronic pilot control work equipment control levers provide quick and precise response to operator input;
  • Automatic dig system, semi-automatic approach and dump system help less experienced operators become more productive and can reduce fatigue for experienced operators;
  • High resolution, 7 in monitor with dedicated rearview camera, and;
  • 45° stairways on the left- and right-hand side of the machine and walkways in front of the cab and on the rear counterweight provide easy access on the machine.

The machine benefits from a number of new technologies, including an advanced machine monitoring system, with onboard diagnostics viewable with the 7 in LCD monitor, which means no laptop is required for machine troubleshooting; KomVision® with radar obstacle detection and a six-camera system on a dedicated LCD monitor to provide a bird’s-eye view around the machine and an audible alert when an obstacle is detected in the working area for improved operator situational awareness (optional); enhanced KOMTRAX® Plus for immediate remote diagnostics of machine heath and performance with operator ID and integration with third-party telematics systems; and energy savings operation ECO guidance provides operator with real-time recommendations to improve machine operation efficiency.

The Komatsu WA900-8 has a completely redesigned front and rear frame and loader linkages making it the most durable chassis in the model history, according to the company. This is complemented by a new standard brake cooling system to reduce brake oil temperature, all of which results in longer brake-service life. An engine pre-lubrication system raises engine oil pressure before startup to ensure full lubrication of all engine components, the company added.

Cat 797F haul truck proves its worth in Tier 4 Final configuration

Cat says its 797F large mining truck is now available in a fuel-efficient configuration that meets US EPA Tier 4 Final emissions standards.

Through more than 16,000 hours of successful pilot machine operation and 100,000 hours of production truck operation in Tier 4 configuration, the system has proven its ability to deliver strong performance and greater fuel efficiency compared to the Tier 2 797F in most applications, the company said.

The 797F Tier 4 Final is equipped with an exhaust aftertreatment system featuring selective catalytic reduction, which uses diesel exhaust fluid (DEF) to lower NOx emissions. This Cat emissions platform is proven through more than 20 million operating hours in the field, according to the company.

The 797F aftertreatment system uses less than 11% new content, improving reliability, while the modular aftertreatment system, with readily accessible components designed for serviceability, is aligned with truck preventive maintenance intervals to maintain high availability, Cat said.

The best-selling truck in the 400-ton (363-t) size class, according to Cat, the 797F is powered by a 4,000-hp (2 983-kW) Cat® C175-20 engine, available with optimised fuel maps for customers focused on the lowest fuel burn, Tier 2 equivalent rating, and now Tier 4 Final. It is renowned for delivering class-leading payload and speed-on-grade performance, Cat said, adding that the 797F delivers the same production performance in Tier 2 and Tier 4 Final configurations.

“Beyond offering similar performance, the Tier 4 Final 797F reduces total specific fluid consumption costs (fuel plus DEF) in most applications,” Cat said. “Lower fuel burn results in longer engine life and lower repair costs.”

Field evaluations of the 797F included a wide range of applications in oil sands, deep pit copper, iron ore and coal mines. The trucks exceeded production targets and demonstrated strong engine performance in all applications, including sites with extreme ambient temperatures as well as some with altitudes greater than 16,000 ft (4,877 m), according to Cat.
