40-Ton-Payload Dump Truck


The Western Star 6900XD is designed to minimize cost-per-ton hauled when compared with traditional articulated dump trucks (ADT) and rigid frame off-road dumps. These savings are achieved by lower acquisition and maintenance costs with optimal hauling performance and productivity. On maintained terrains and hauls that exceed one-half mile (0.8 km) Western Star claims the 6900XD is 35% more fuel efficient than competitive ADT and rigid dumps in the same payload class. On longer hauls in excess of 12 miles (20 km) the 6900XD has posted average fuel consumption of 7.13 gal/h (27 L/h). A heavy-duty Allison 4500RDS automatic transmission, in combination with robust Axletech planetary gear drive axles, provides for efficient power shifting and optimal axle ratios between 10 and 12:1. This results in less reduction gearing, power loss and heat increase in the transmission compared with drop boxes and transfer cases typically used in ADTs and rigid haulers. The 6900XD employs a durable and economical dry drum brake design and is equipped with a standard Jacobs compression brake. A hydraulic transmission retarder is an option. The dump box is constructed of 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 scowled end to secure large boulders and reduce hydraulic cylinder stress upon boulder impact. The auto lift tailgate maximizes material loading while the full cab guard protects the operators cab from falling debris.
