L48A1 Mast Section 986/5000 How can the steel rope of the tower be used for a long time
How to use and maintain the steel wire rope of the tower crane to avoid the accident caused by the fault of the steel wire rope of the tower crane.
1. When the load is supported by multiple wire ropes, a balance device in the hands of each wire rope shall be provided.
2. The lifting mechanism and the lengthening mechanism of the tower crane shall not use the wire rope with long binding. When using other methods to connect a steel wire rope, it must be ensured that the connection strength of the joint is not less than 90 % of the breaking tension of the steel wire rope.
3. A tower crane with a large lifting height should use a steel wire that does not rotate and has no loose tendency. When other wire ropes are used, there shall be devices or measures to prevent the rotation of wire ropes and hangers.
Four. When the hook of the tower crane is at the lowest point of the working position, the winding of the wire rope rewinding tube must be no less than 3 laps in addition to the number of circles fixed at the end of the rope.
