Abstract:
A hoist with a regenerative resistor contains the following in a casing: a load-raising/lowering motor driven by an inverter control device and provided with a forced-cooling means; and a mechanism part containing a reduction mechanism part and a load sheave that uses power from the reduction mechanism part to take up and let out a chain. The load-raising/lowering motor, mechanism part, inverter control device, and regenerative resistor are distributed inside the casing to achieve a balance of weight about the center of gravity of the load applied when raising or lowering. Also, the inverter control device and the regenerative resistor are affixed to the casing, in close contact therewith, in parts of the casing separated from each other with the mechanism part therebetween.
