In the traditional cable crane installation construction process, because two tower top portal main trusses are positioned on the tower top, the space between the tower top portal main trusses is small and is influenced by the width of a catwalk, the cable crane cannot be hoisted at the position between the two tower top portal main trusses, a walkway distribution beam must be overhung out, a cable crane walking mechanism and a cable crane load beam are vertically hoisted at the position where the walkway distribution beam is overhung out, and after the vertical hoisting is completed, in the transverse moving process, due to the blocking effect of the tower top portal main trusses in the middle, the cable crane walking mechanism can only be moved to the position right above a main cable in a skew pulling and oblique hoisting mode and then is lowered for walking installation. The hoisting construction method of the traditional cable crane walking mechanism comprises the following steps: when the cable crane walking mechanism is vertically hoisted to the position above the main cable through the hoisting steel wire rope, the movable pulley group and the hoisting distribution beam, the movable pulley group and the hoisting steel wire rope which are positioned at the position of the main cable on the pavement distribution beam are hooked on the cable crane walking mechanism, at the moment, the cable crane walking mechanism is simultaneously under the hanging action of the hoisting steel wire rope and the hoisting steel wire rope, then the movable pulley group is slowly tightened, the movable pulley group is loosened, the cable crane walking mechanism gradually moves to the position of the main cable, and finally the cable crane walking mechanism swings to the position right above the main cable to finish the transverse movement of the cable crane walking mechanism. The transverse moving mode of the load beam of the cable crane is the same as that of the running mechanism of the cable crane.

therefore, there is a need for a cable crane mounting mechanism to solve the current technical problems.
