detailed description

A kind of elevator shaft operation platform of the present utility model is described in detail below in conjunction with accompanying drawing.

As shown in the accompanying drawings, the elevator shaft operating platform of the present utility model has a structure comprising an elevator shaft 1, an elevator shaft wall shear wall 2,

Horizontally opposite reserved holes 3 are respectively opened on the two opposite elevator shaft wall shear walls 2;

The two ends of more than two supporting rods 4 arranged in parallel are connected to the horizontally opposite reserved holes 3 on the shear wall of the elevator shaft wall;
