Western Star Trucks, Klein Products develop 6,500-gallon water tank truck

Western Star Trucks Inc announced the availability of a 6,500-gallon water tank truck for its 4900XD. Developed in collaboration with Klein Products Inc, the truck features a Klein K650 water tank to provide a more efficient road dust control operation for construction, quarry, and mining applications.

Ontario CA-based Klein is a manufacturer of water distributing equipment, patented pump systems, and related components. Western Star sought Klein to develop the specialized 4900XD water tank truck based on its ability to outfit the vehicle with a high-volume water distribution system.

Available to order in a day cab configuration, the 4900XD is equipped with Klein’s largest water tank for Class 8 vehicles, reducing the need for frequent refill trips when spraying mine roads, waste rock dumps, and other exposed surfaces.

The 4900XD features an extremely low center of gravity and is available with a rollover protection system (ROPS). The truck is also spec’d with outboard cab mounts and up to 20,000-lb front and 70,000-lb rear suspension to maximize stability on uneven terrain and provide a more comfortable ride. Additionally, the Klein K650 tank’s distinctive trapezoid design greatly improves rear visibility for drivers.

Spec’d with a sturdy, custom-drilled 3.8 million RBM steel frame chassis, galvannealed steel cab, and aluminum fenders, the 4900XD water tank truck provides critical protection and long-term durability, even in adverse job conditions.

The 4900XD can be equipped with a fuel-efficient Detroit DD15, DD16, or DDC 60 Tier III engine, each easily accessible through the truck’s three-piece butterfly hood.
