HOIST

摘要

A hoist capable of high frequency operation by efficiently releasing heat of an inverter, which is incorporated in a hoist body, to ambient air by using a simple structure. The hoist has a load lifting and lowering electric motor and a reduction gear mechanism, and the motor is driven by the inverter (12) incorporated in the hoist body. The hoist further has heat release means for releasing heat emitted from the inverter (12) to a reduction gear mechanism casing (15). The heat release mechanism is installation means for installing the inverter (12) on the reduction gear mechanism casing (15) with at least a part of the inverter (12) made to be in direct intimate surface contact with the casing (15).
