　　If the use of the crane is as follows:

　　When the crane cable is in a zigzag arrangement

　　1.The length of free use is more than 35m.

　　2.The running speed is more than 1.6m/s. Consideration should be given to the addition of load-bearing elements in cables, which are usually galvanized soft wire ropes or fibre ropes such as aramid yarns.

　　When the hoisting cable is twisted and arranged in plum blossom type:

　　1.Free suspension length greater than 80m

　　2.The running speed is 4.0m/s-10m/s. Consideration should be given to the addition of load-bearing elements in cables, which are usually galvanized soft steel wire ropes
