包括再生制动电阻的起重机
摘要：
根据本发明的起重机包括：电机部、减速器部和电力控制部。所述起重机中，由电力控制部供应的电源驱动电机部，电机部驱动减速器部且与减速器部连接，减速器部升降吊有重量物的链条。所述电力控制部，包括：逆变器，所述逆变器用于向电机部供电，以及再生制动电阻，所述再生制动电阻用于将电机部的发电模式下产生的电转换成热能。所述逆变器和所述再生制动电阻分别容纳于逆变器外壳和再生制动电阻外壳，所述逆变器外壳和再生制动电阻外壳固定于内部填充有润滑油的减速器部外壳的各自不同的外侧面上。在固定于减速器部外壳的外侧面上的状态下，所述逆变器外壳和再生制动电阻外壳不直接接触，互相之间存在间隙。
摘要（英）：

A hoist according to the invention comprises a motor unit, a reducer unit, and a power control unit. In the hoist, power supplied from the power control unit operates the motor unit, the motor unit drives the reducer unit and is connected to the reducer unit, and the reducer unit raises or lowers a chain in which a weight is hung. The power control unit includes an inverter supplying power to the motor, and a regenerative brake resistor converting the power generated in a generation mode of the motor unit into heat energy. The inverter and the regenerative brake resistor are stored in an inverter casing and the regenerative brake resistor casing, respectively. The inverter casing and the regenerative brake resistor casing are fixed to different outer side surfaces of the casing of the reducing unit into which lubricating oil is charged. When fixed to the outer side surfaces of the casing of the reducer unit, the inverter casing and the regenerative brake resistor casing are not directly attached and have a space formed therebetween.
