Description

A special spreader for horizontal clamps

technical field

The utility model relates to a sling, in particular to a special sling for a horizontal clamp, which belongs to the technical field of cranes.

Background technique

In the production of the cold rolling production line, it is very frequent to use the crane horizontal clamp to lift steel coils. The production links such as the storage of steel coil raw materials, the loading and unloading of each unit production line, and the delivery of finished coils are all hoisted by horizontal clamps. When transporting steel coils, the horizontal clamp is connected to the crane hook through a pin shaft, and the control cable of the horizontal clamp is connected to the control system of the crane through the control box. Since the horizontal clamp can only be used to lift steel coils, on-site When it is necessary to lift heavy objects such as spare parts, equipment and waste materials, it is necessary to remove the horizontal clamp and then use the crane hook to lift. The disassembly and assembly of the horizontal clamp is very troublesome and time-consuming. It is necessary to disassemble the pin shaft connecting the horizontal clamp and the crane hook, and the control circuit of the clamp needs to be disassembled. The operation is time-consuming and laborious, which affects the on-site production rhythm and output. When the site is busy, sometimes when the site operation is lifting heavy objects other than steel coils such as re-separated coils, scrap edge wire coils, etc., the steel wire rope is directly hung on the hook head of the horizontal clamp without removing the horizontal clamp. , It is easy for the wire rope to scratch the hook of the horizontal clamp and the wire rope slips from the hook of the horizontal clamp, causing the lifting object to fall and damage the equipment or cause personal injury, which poses a great safety hazard.
