초록

A cab heating system for material handling equipment which maximizes energy savings by utilizing the heat generated during hydraulic operation. The cab heating system has a hydraulic control unit which controls a material handling implement. A heat exchanger is positioned downstream of the hydraulic control unit. Air flowing through the heat exchanger is heated by the hydraulic fluid and blown by a fan into the interior of the cab. The heating system can also have an auxiliary heat exchanger to further heat the hydraulic fluid. In one embodiment, the aux...
