ABSTRACT:
A cable retraction speed limiter has a body which is designed to be mounted on the housing of a hoist and a spool which is rotatably supported by the body. A flexible extension member is disposed about the spool so that it can be extended from and retracted onto the spool by rotation of the spool. The end of the flexible extension member is designed to be attached to an air pressure responsive member inside of the air balancing hoist. The cable retraction speed limiter also includes a spool lock that stops rotation of the spool when the rotational speed of the spool exceeds the rotational speed limit, thereby limiting the hoist cable retraction speed.
