Bare chassis for 785 construction dump truck

Construction dump trucks (CAT)

Caterpillar offers incomplete machines and systems in collaboration with Cat dealers and original equipment manufacturers (OEMs) to provide specialized machines for specific applications. Bare chassis dump trucks (WTR models) can be ordered with or without lift cylinders, and most product options are identical to those of dump truck models. In general, these models have the higher ROPS (Rollover Protective Structure) tractor certification required for specialized machines such as tanker trucks, tow tractors, and fuel/lubricant tanker trucks. These incomplete machine configurations are used in construction, demolition, waste handling, material handling, quarrying, and mining applications.
