A patient lift has a base, a mast assembly mounted on the base at the lower end, a boom pivotally mounted at one end on the mast assembly. An actuator is mounted on the boom and configured to move between a retracted position and an extended position to pivot the boom relative to the mast assembly between a lowered position and a raised position. A support member includes a sling attachment pivotally mounted on the outer end of the boom. A locking mechanism is configured to fix the support member relative to the boom when the locking mechanism is engaged and further configured to allow pivotal movement of the support member relative to the boom when the locking mechanism is released.
