Abstract
A patient lift including a lifting member and a hoist assembly connected to the lifting member. The hoist assembly has an enabled state to move the lifting member between a raised position and a lowered position, and a disabled state wherein the hoist assembly cannot move the lifting member between the raised and lowered positions. An elongated switch member descends from the hoist assembly such that the switch member is reachable by an operator. Urging the switch member in a first direction in an axial sense along the length of the elongated switch member or a rotational sense about the length of the elongated switch member, places the hoist assembly in the enabled state or the disabled state. Urging the switch member in a second direction different from the first direction places the assembly in the other of the enabled state and the disabled state.
