A lifting hook is a device for grabbing and lifting loads by means of a device such as a hoist or crane. A lifting 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.
A hook may have one or more built-in pulleys to amplify the lifting force.
In 2009 Elebia presented the autohook, a completly new concept of lifting hook. This automatic crane hook generates a magnetic field that attracts and guides the ring or the sling. The user presses a button on the remote control and the crane hook closes automatically.
