The purpose of this arrangement is to enable efficient assembly of the main beam 10 to the cable head 52 by means of the pin 80 (see fig. 2). However, the difficulty of the assembly is that the matching of the distance sizes of the L1 and the L2 is difficult to guarantee, and the distance between the L1 holes is guaranteed by machining on the main beam 10 and meets certain precision requirements. However, the hole spacing size of the L2 is completely established on the randomness of cold-work assembly, and the outer circle of the pin shaft 80 and the inner circle of the hole have certain matching precision, so that when the size between the L1 and the L2 is large, a worker cannot easily adjust the hole shaft in place for assembly, and the whole weight of the combined rope head 52 reaches hundreds of kilograms, so that the assembly difficulty of the worker is increased.
