A patient lift including a boom a spreader bar, and a friction coupling for securing the boom and the spreader bar. The friction coupling may include two friction washers disposed against respective inner faces of the boom. Two compression springs are disposed abutting the friction washers with a spreader bar support member in between. The compression springs urge the friction washers against the inner faces of the boom end. The spreader bar does not swing when the lift is moved without load. Also, the friction coupling reduces the swing of the patient, when transferred in the lift. This makes the lift easier to maneuver for the caregiver. |
