Hoist wire rope sag prevention device of tower cranes

摘要

The subject innovation relates to a hoist wire rope deflection allowed to stand apparatus of the tower crane, the trolley wire rope 32 and the hoist wire rope 22, the trolley rope guide 45 each formed a sliding hole 47, 52 a through the middle and hoist rope guide 50 is fastened and the trolley rope guide 45 and the hoist rope guide 50 are each guide support which is connected to the rope 55. on the other hand, the trolley rope guide 45 of the front side of the trolley wire rope 32, the wire rope holder 60 is fastened and the guide supporting ropes 55 and the wire rope holder 60 is made is connected to the spring 68, the hoist 20 and the trolley 30 the hoisting device 10 is moved towards the driver's seat 70, without the use of the hoist wire rope 22 hoengseol if a long period of time to stop and hold the wheel (70) and the jib (90) ends because of the sag into Kwon Sang-ha consisting of To be generated, the trolley wire rope 32 and the hoist wire rope 22 between the trolley wire rope guide 45 and the hoist wire guide which connects the rope guide 50 supporting ropes 55 and the elasticity spring ( by 68) to thereby suppress the deflection phenomenon of the hoist wire rope 22.
