Crane hook is a device for grabbing and lifting loads 
by means of a device such as a hoist or crane. 
Introduction
Hook structure
Note: Hook is usually equipped with a safety latch 
to prevent the disengagement of the lifting wire 
rope sling, chain or rope to which the load is 
attached.
Hooks can be classified into single hook and double 
hooks according to the appearance; forged hooks 
and strapped hooks according to production 
method.
Xinxiang Degong Machinery Co.,Ltd
Which hook to choose?
Single hook for crane
Capacity of Single Hook:
5t/6t/10t/12t/16t/20t/25t/32t/4
0t/50t/63t/80t/100t/125t/160t/
200t/250t
Single hook is easy to 
produce and use, but its load 
carrying is not good, so most 
of time, it is only used at the 
low capacity working 
site(less than 80T).
