swivel crane hook are one of the most suitable slings in hoisting. It is connected with pulleys to hang on the wire rope of lifting mechanism. And the hook is the most widely usage when lifting cargos. It is made easily and operated practically. Hooks can be classified into single hook and double hooks according to the appearance; forged hooks and strapped hooks according to production method.
Application
It is widely used in all kinds of machines for lifting goods.
Materials
M grade with DG20, or DG20Mn
P grade with DG20Mn
S grade with DG34CrMo
T grade below 40t with DG34CrMo, more than 40t with DG34CrNiMo or DG30Cr2Ni2Mo
V grade below 40t with DG34CrNiMo or DG30Cr2Ni2Mo, more than 40t with DG30Cr2Ni2Mo.
Features
Single hooks is easy to produce and use, but its load carrying is not good, so most of time, it only be used at the low capacity working site(less than 80T); when the capacity is large, double hook with symmetrical load carrying will be used. Strapped hooks is riveting by several cutting forming steel plate, respective steel plate has fissure will no broke the total hooks using, and its safety feature is better, but its self-weight is large, mostly be used in large capacity or lifted molten steel cranes.
