The counterweight block 5 is fixed to the top of the movable seat 1, which can achieve a balancing effect when lifting heavier objects, thereby improving the stability during construction.

[0040] The working principle of the utility model is as follows: after the staff moves the mobile seat 1 to the designated use position through the rollers at the bottom, the equipment and cables that need to be lifted are placed on the top of the load-bearing plate 101 and fixed with ropes, and then the dual-axis motor 201 is started through the external controller, and the dual-axis motor 201 cooperates with the transmission rod 202 to drive the winding roller 103 to rotate, and the winding roller 103 cooperates with the steel cable 203 to pull the load-bearing plate 101 to achieve the lifting effect on the electrical equipment.
