The difference between the upper and lower hooks of manual lifting hoists
The manual lifting hoist is divided into upper and lower hooks, with the upper hook connected to the lifting point as a fixing, and the lower hook connected to the chain. The same form is used in electric lifting hoists, all of which use safety anti detachment devices with locking plate springs. The overall strength is maintained through forging technology, and the models can be divided into X type, A type, and V type.
The difference between upper and lower hooks
1. Except for the difference in the position of the upper hook axis, the upper and lower hooks are the same everywhere else. The left and right wall panels above the hook axis position need to be connected to the gourd, and the chain links below and at the end of the connecting chain.
When the single chain hoist chain is connected, one hook is combined with a bolt. If it is a double chain or multiple chain hoist (large tonnage), a sprocket will be used at the hook shaft position to facilitate the rotation of the chain, which is similar to the combination of a pulley and a steel wire rope, and the double rope steel wire rope electric hoist.
The difference between single chain and double chain is not only reflected in the hook, but also in the speed and load. The hook body of the hook is the same, and it needs to hang heavy objects, so in some special needs, both manual and electric models also have upside down hanging.
The hanging hook is often hung on different lifting points, such as steel rail clamps and lifting rings on I-beams; The lower hook needs to be connected to the lifting belt eye, steel wire rope, American style hook binding chain, etc. Not only does it require the correct method, but it also requires stable force without sliding.
