For example, a lifter is conventionally used to attach or remove a circuit breaker or the like to or from a switchboard. FIG. 8 is a side view showing the structure of such a lifter, and FIG. 9 is a front view thereof. As shown in FIGS. 8 and 9, this lifter has a vertical frame 14 fixed vertically to the end of a rectangular bottom frame 13 which is parallel to the floor and has wheels 12 for traveling on the floor at both ends. A loading platform 15 which is guided by the vertical frame 14 and moves up and down in the vertical direction is provided. The platform 15 is moved up and down by a hoisting device including a rope 16, pulleys 17A, 17B, 17C and a hoisting unit 18 including a handle and a gear device.

Next, the hoisting unit 18 is operated to move the cargo bed 15, and thus the equipment mounted on the cargo bed 15, to the switchboard 6.
Raise to the device mounting height inside. Further, the lifter is brought closer to the switchboard 6 or brought in into the switchboard 6 in some cases, the device is fixedly mounted on a mounting frame or the like, and then the lifter is pulled out to finish the mounting of the device. In addition, a device installed in the switchboard, such as a circuit breaker, may be installed in the switchboard 6
When carrying out from the hoisting unit 1, the lifter is first brought close to the front surface of the switchboard 6 or carried into the switchboard 6.
8 is operated to raise the platform 15 to the height at which the device is mounted, and then the device is removed from the device mounting frame or the like inside the switchboard 6 and the device is placed on the platform 15. Thereafter, the lifter is pulled out from the switchboard 6 with the device placed on the loading platform 15 to complete the unloading of the device.

に作業性が悪い。In such a method of attaching or detaching a device using a lifter, when the target device is large and heavy, the weight balance is lost when the lifter carrying the device is moved and the lifter falls over. The lifter may be provided with a counterweight for weight balance in order to prevent this. However, in this case, there is a drawback that the lifter becomes large. In addition, the lifter itself blocks the front surface of the work portion where the device is attached or detached, so the workability is poor.
