초록

An apparatus is provided that quickly elevates and maintain a construction equipment engine coolant to operating temperature in order to lower the dwell time for the operator's cab to reach a comfortable temperature level during a period when the engine is in idle and main crane functions are not operated. The apparatus includes an auxiliary hydraulic circuit for rapidly bringing engine coolant temperature up to operating temperature. Engine coolant operating temperature is achieved by inducing a hydraulic load to the engine. By inducing a hydraulic load...

청구항

1. A crane having a drive engine, a pump driven by the drive engine, and a hydraulic system for powering main crane functions, and wherein: a) the drive engine is cooled by an engine coolant loop that also directs the coolant to a heat exchanger that thereby provides heat to the operator cab, andb) the hydraulic system includes an auxiliary hydraulic sub-system imposing a horsepower load to the drive engine, the auxiliary hydraulic sub-system comprising: i) at least one pressure reducing relieving valve that limits inlet pressure to the auxiliary hydraul...
