HOIST

摘要

A hoisting machine is provided that is capable of efficiently dissipating heat generated from an inverter incorporated in the hoisting machine main body into the surrounding air with a simple structure and hence capable of performing high-frequency operation. A hoisting machine having a load hoisting motor and a speed reduction mechanism and driving the load hoisting motor with an inverter 12 incorporated in the hoisting machine main body is provided with a heat dissipation means that dissipates heat generated from the inverter 12 to a speed reduction mechanism casing 15 that houses the speed reduction mechanism. The heat dissipation means is a means for attaching the inverter 12 directly to the speed reduction mechanism casing 15 in close contact therewith through surface contact at at least a part of the inverter 12.
