る方法が採られている。For this reason, in general, a braking resistor (9b) is separately provided to prevent the voltage rise from exceeding a certain value, and the regenerated energy is transferred to the resistor through a switching element (9a) such as a transistor that operates at a constant voltage. A method is adopted in which the power is consumed by a power converter (9b), or by a forward converter (a method in which the power is made reversible and returned to the AC power source).

The regenerative energy is supplied to the battery (6) by igniting the battery (9b) slightly before it is turned on, which corresponds to mainly floating charging of the battery charging device.

When the crane is not in use, charging is performed mainly by equal charging using the rectified output of the AC power source through a forward converter.
