An inverter for a crane is rapidly stopped and rapidly separated from a circuit in the event of an anomaly. Provided are a motor (11), an inverter (12) provided correspondingly with respect to the motor (11), a converter (13) for converting AC power supplied by an AC power supply to DC power and supplying DC power to the inverter (12), a power consumption unit (21) connected between the converter (13) and the inverter (12) for consuming DC power from the converter (13), and a first switching unit (MC1) connected between the power consumption unit (21) and the converter (13) for switching between connection and separation of the power consumption unit (21) and the converter (13). |
