When using a ladder, one person needs to support it, and only one person can work on the ladder, and anti-skid and height limit measures must be taken. However, the rural pole-type power distribution counter areas are distributed in the vast countryside, and the transportation is inconvenient. Sometimes the power distribution counter areas are selected in the fields, and it is very inconvenient to borrow tool ladders.

In the pole-type power distribution counter area with complex terrain, the maintenance personnel use the foot buckle to mount the pole to fix the power distribution cabinet to maintain and manage the equipment in the power distribution cabinet. When using the foot buckle to operate the equipment in the power distribution cabinet, the work The standing posture of the staff is inconvenient for long-term operation, and the staff are prone to fatigue. Because the distribution transformer bench is more than 2 meters wide, the side of the power distribution cabinet is far away from the staff, and the equipment cannot be reached by hand, which is inconvenient to operate. It is not easy to use force when using tools such as wrenches.
