In a crane for suspending one load handling device by two trolleys, even when the interval of the two trolleys is changed, a power supply cable can be easily supplied to the load handling device. When the interval of two trolleys (100B, 100C) are changed by an interval adjusting device (110), the suspension position of a power supply cable (96) is moved at the half speed of the interval changing speed. The position of an operating cabin (180) is moved similarly to the suspension position. For that reason, even when the interval of two trolleys (100B, 100C) is changed, the suspension position of the power supply cable (96) relative to the cable basket (95) of a load handling device (90) is not changed. Similarly, the position of the operating cabin (180) relative to the load handling device (90) is not changed.
