DISENGAGING APPARATUS Abstract Disengaging apparatus including a hook having its pivot point and its engaging point substantially vertically aligned, being positioned between a pair of plates and having an integral counterweight extending laterally from the engaging point. A first link is attached at one end to the lateral extension and at the other end to the first end of a second link which rotates about a fixed point. The links have a first extended position under a load and rotate to a second position, thereby rotating a constant-radius engaging surface of the hook about its center at the pivot point of the hook in light or no load situations. Additionally, a stop and locking members may be provided to prevent accidental release of the hook.
