What is a lifting hook?

A lifting hook is a device used as part of a jack, pulley system or other lifting system to ensure load for movement. The hook itself may vary in size, shape and functions, and most of them are made of heavy metal such as steel. A lifting hook is likely to have a latch that will surprise to the place to close the mouth of the hook; This prevents ropes or cable secured with a hook from slipping from the lip and unstable or completely falling. The lifting hook can be attached directly to the cable or rope, although in some cases the hook has some kind of chassis or frame that allows it freely and independently of the cable itself. This independent movement prevents cable winding and potentially binds or breaks when load movement. Instead, the hook turns around, allowing the load to be rotated without turning the cable itself. The swivel lifting hook We are mounted on larger systems, although very small, light lifts can also equip such a rotary device.

The

shape of the hook generally looks like J and lips usually stand out slightly externally to protect the tip from capturing on a rope or other materials that have been raised. The gate closes the open end J, similar to the gate of the carabiner used for climbing. The gate is usually loaded on a spring to prevent accidental opening during use, but is not a device carrying a load. It simply prevents the rope or cable from slipping from the hook while using.

Sometimes the lifting hook is designed for use with a chain. If this is the case, the hook is often attached to the chain using the kotter assembly. This system is equipped with a screw without a fiber that slips through the opening on the hook; The string can be powered around this screw and then the bolt slipped the Thdrny with another opening on the hook. Once there is a place, the kotter pin slips through the hole in the screw to ensure that it does not slip back through the hook hole. TheseThe assemblies are easy to use and generally relatively reliable, although Cotter and PIN often have to be large depending on the size of the hook itself and the weight capacity for which it is evaluated.
