The lifting hook is installed on the load-bearing lifting plate and passes through the base to hook on the cable.

[0006] Preferably, the base comprises a support base, a lifting hook fixing plate, a support arm and a support buckle. The lifting hook fixing plate is horizontally and fixedly installed on both sides of the support base. Two groups of support arms are fixedly installed below the support base. The support buckle is fixedly installed below the support arm. The support buckle is fixed on the wrist arm.

[0007] Preferably, four through holes are formed in the load-bearing lifting plate and are located at the four corners.

[0008] Preferably, four through holes are formed in the lifting hook fixing plate horizontally and fixedly installed on both sides of the support base and are located at the four corners.

[0009] Preferably, the hook is fixed on the load-bearing hanging plate by bolts and passes through two diagonal through holes on the load-bearing hanging plate and a through hole on the hook fixing plate.

[0010] Preferably, the through hole on the load-bearing hanging plate and the through hole on the hook fixing plate are in communication.

[0011] The utility model discloses the beneficial effects are:

[0012] 1, when the utility model is used to replace the bearing cable base and bearing cable protective sleeve, the tool use and personnel occupation are reduced, the structure is simple, the structure is stable after installation, convenient installation can stably solve the bearing cable base stress problem.

[0013] 2, the bearing cable base does not need manpower to lift, uses the jack to lift, simplifies the personnel operation, and reduces the security risk.

[0014] 3, the whole device use time is greatly shortened, and the operation efficiency is greatly improved.

[0015] 4, the operation space of equipment replacement is reserved, and the operation is facilitated.

[0016] 5, the up and down and left and right reserved positions can be adapted according to different situations on site. DETAILED DESCRIPTION
