Abstract

See full text

Provided in this disclosure is a digger/derrick system (or generally any type of machine) having a diesel engine to power a hydraulic system for raising and lowering the digger/derrick and powering other components. The system includes a centrifugal clutch that engages the diesel engine while the engine is running, thereby powering an electrical generator that drives the hydraulic pump while also charging an on-board battery bank system. When the engine is turned off, the centrifugal clutch is decoupled. The battery banks then power the generator, which in turn drives the hydraulic pump. In this manner, the digger/derrick offers the advantages of noise reduction as the hydraulic systems can be operated without running a noisy diesel engine. This noise reduction after enhances safety since operators elevated in the derrick and operators on the ground can more readily communicate to give clear warnings to avoid danger and other undesirable circumstances.
