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.


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/250tSingle 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).
