EQUIPMENT CHARACTERISTICS, CAPABILITIES AND FEATURES
The M876 Truck characteristics, capabilities and features are described in TM 9-2320-269-10.
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS
DERRICK EXTERIOR
The derrick subframe is steel fabricated and welded into one unit. Subframe includes derrick mast, outriggers, and derrick
operator's control console. The subframe mounts on and is bolted to the M876 Truck frame. The subframe derrick mast
supports the derrick and distributes loads to the M876 Truck frame.
The derrick operator's station is a hydraulic control platform that houses the selector control valves which operate the
derrick. It also has an independent throttle control to increase engine rpm required during derrick operations.
The outriggers are four hydraulically operated jacks to stabilize the M876 Truck during derrick operations. The outriggers
have an interlock safety system that prevents derrick operation until all four outriggers are lowered.
