How to choose hook?
Capacity of Single Hook: 5t/6t/10t/12t/16t/20t/25t/32t/40t/50t/63t/80t/100t/125t/160t/200t/250t
Single hook is easy to produce and use, while its load carrying is not good, usually it is used at the low capacity working site(less than 80T).
Capacity of double hook: 10t/12t/16t/20t/25t/32t/40t/50t/63t/80t/100t/125t/160t/200t/250t.
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 its safety feature is better, while its self-weight is large, mostly be used in large capacity or lifted molten steel cranes.
Five strength grades M, P, S, T, V, are classified in accordance with mechanical property.Forging hook and strap type hook are manufactured according to method of manufacturing.
Hook 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
Hook Test：
In order to ensure safety, hook must pass the test, when found to be one of the following
conditions, the hook must be set to be scrapped, welding repair is not allowed. please send us a detailed inquire so we can try to quote price for you, thanks!
