Further, when the chain connecting assembly is arranged below the shoulder pole beam, the chain connecting assembly comprises a clamping plate pin shaft, a chain pin shaft, a clamping plate, a connecting plate and a mounting plate, wherein the mounting plate is fixed below the shoulder pole beam and is provided with a crack structure, the top of the connecting plate is inserted into the crack of the mounting plate and is fixed on the mounting plate through the clamping plate pin shaft, the mounting plate extends out of the bottom of the connecting plate, and the chain is inserted into the bottom of the connecting plate through the chain pin shaft.

Further, the distance between the chain connecting components is 5.86-6.3 m.

Further, the chain connecting mechanisms are two groups, the distance between two chain connecting components of one group of chain connecting mechanisms is 5.86m, the two chain connecting components are both arranged below the shoulder pole beam, the distance between two chain connecting components of the other group of chain connecting mechanisms is 6.3m, and the two chain connecting components are both arranged below the shoulder pole beam.

Furthermore, the lower end point of the chain is provided with a welding hanging ring.

Furthermore, the upper surface of the shoulder pole beam is connected with a pulley for hanging the steel wire rope.

The utility model has the advantages that:

the utility model discloses increase one or more chain sling hanging points on original supporting hoist, this chain sling passes through chain coupling assembling and directly or indirectly is connected with the shoulder pole roof beam, when one of them size of needs, with the chain sling hang in this department can, consequently reached the purpose of the free choice of hoist size through this simple structure's device, make the dregs soil box unanimous with the hoist size, guaranteed the handling security.

Other features and advantages of the present invention will be described in detail in the detailed description which follows.
