GRAB MECHANISMS
Abstract
This patent relates to a device for ltfting objects having specially designed arms that fit into aligned slots within concentric sleeves of the grab mechanism. Upon the application of an electric current the sleeves are rotated relative to one another to the aforesaid aligned position, aliowing the entry or removal of the arms of the lifted object. The sleeves are spring biased to an unailgned positione thus locking the arms within the grab mechanism when the current is off. This arrangement provides a device that will remotely secure, life, and release an object, wtth the assurance that the object wiil remain securely locked during the lifting operation.
