Western Star 6900 D Specifications Sheet

Overview The Western Star 6900XD
Western Star 6900XD is designed to minimise cost-per-ton hauled as compared to traditional articulated dump trucks (ADT) and rigid frame off-road dumps. These savings are achieved by lower maintenance costs and high productivity. The efficient and purpose-built design of the 6900XD hauler allows for speed and stability while providing outstanding fuel efficiency. The end result is increased productivity per cycle and maximum profit per ton hauled.

Built for the Long Haul
The longer the haul, the better the Western Star 6900XD performs when compared to traditional off-road haulers. On maintained terrains, and hauls that exceed 1km, the Western Star 6900XD is up to 30% more fuel efficient than competitive ADT and rigid dumps in the same payload class. On longer hauls the fuel savings are even greater.

Key Design Features
Drivetrain Simplicity: The heavyduty Allison 4500RDS automatic transmission, in combination with robust Axletech planetary gear drive axles, puts power on the ground efficiently. This results in less reduction gearing, power loss and heat increase in the transmission compared to inefficient and high maintenance drop boxes and transfer cases typically used in compeditive products.

High Pressure Tyres: (10) 14R25 tyres with earthmoving tread provide maximum stability allowing the 6900XD to comfortably travel at a top speed of up to 70km/h. The smaller diameter tyres with a reduced rolling resistance provide for superior fuel efficiency and cycle speed when compared to larger diameter low pressure flotation tyres. All for about 40% of the replacement cost, should a tyre fail prematurely

Braking System: The 6900XD employs a durable and low-cost dry drum brake design, rather than wet disc brakes that consume higher amounts of fuel due to the inherent drag from rotating discs in oil. The 6900XD is equipped with a standard engine compression brake, providing 373kW of retardation. An optional hydraulic transmission retarder provides 600bhp (447kW).

Heavy-Duty Dump Box: The dump box is constructed from HARDOX 400 steel and is designed to handle the most extreme materials. The low profile sides are designed for easy and efficient loading with a scowed end to secure large boulders and reduce hydraulic cylinder stress upon boulder impact. The auto lift tailgate maximises material loading while the full cab guard protects the operators cab from falling debris.

Superior Operator Comfort: The 6900XD truck is built for work, but the operators cab is built for comfort. From the air-ride cab, a premium insulation package, adjustable air-ride seat with active air lumbar, an expansive dash with highly visible LED lighting, the 6900XD can’t shorten the hours on the job, but it can make the time spent more comfortable and ultimately much more productive.
