777 (07) Bare Chassis
Caterpillar offers partial machines and systems, working with Cat dealers and Original Equipment Manufacturers (OEMs) to provide specialty machines for specific applications. Bare chassis trucks (WTR models) can be ordered with or without hoist cylinders and most product options are identical to the dump truck models. Typically, these models come equipped with the higher Tractor ROPS certification ratings needed for specialty machines including water trucks, tow trucks, and fuel / lube trucks. These partial machine configurations are used in construction, demolition, waste, material handling, quarry, and mining applications.
The Cat Water Delivery System (WDS) is available as an optional attachment with the 777 WTR, 785D WTR, and 789D WTR Off-Highway Truck Bare Chassis and includes factory installed controls in the cab, a hydraulic pump and motor, a water pump and stainless steel spray heads. Whether your goal is dust control or haul road maintenance, the Cat WDS is designed to put water to the ground in a controlled, intelligent way. The simple to operate automated system allows you to concentrate on more important safety issues like traffic, personnel and road conditions. You'll also find that the Cat WDS not only improves safety, but also reduces truck maintenance costs, conserves water and provides significant fuel savings to help your bottom line.
