Background technique
Suspension hook is one of the most common type suspender in hoisting machinery.Suspension hook is often by means of member hangs such as pulley blocks in raising
On the wirerope of mechanism.Single hook is simple to manufacture, is easy to use, but stress condition is bad, and being used in lifting capacity mostly is 80 tons or less
Workplace；Frequently with the symmetrical double hook of stress when lifting capacity is big.Stacked suspension hook is riveted by the steel plate that several pieces are cut and formed
Form, individual plates when cracked entire suspension hook will not destroy, safety is preferable, but it is larger to be self-possessed, and is used in big lifting mostly
Amount or handling molten steel are contained on the crane of bucket.Suspension hook is often hit in operation process, must use the Fine Steel Casting iron of good toughness
Manufacture.
Suspension hook is one of suspender most commonly seen in lifting equipment, is suspended on lifting equipment by elements such as pulley blocks and rises
On the wirerope for rising mechanism；The object for needing to lift is hung on suspension hook after wirerope or chain lockset binding, it can
Carry out lifting work；Commonplace suspension hook used at present is goat's horn suspension hook, and suspension hook is easy to happen rope in hoisting process
Perhaps chain lockset fall off and cause the safety of staff to go wrong simultaneously because rope or chain lockset weight compared with
Greatly, make to unload rope or when chain lockset is time-consuming and laborious, increase the labor intensity of operator, reduce working efficiency.
Summary of the invention
In order to make up for the deficiencies of the prior art, solution suspension hook is easy to happen rope in hoisting process or chain lockset is de-
Fall and the safety of staff caused to go wrong, simultaneously because rope or chain lockset weight are larger, make to unload rope or
Time-consuming and laborious when person's chain lockset, the problem of increasing the labor intensity of operator, reduce working efficiency, the present invention is proposed
A kind of hook rigging.
