Abstract
A patient support apparatus includes a frame supported relative to a floor, the frame configured to support a deck for supporting a patient thereon, and a lift assembly for raising or lowering the frame relative to the floor. The lift assembly includes lifting legs coupled to the frame and an actuator with a body and an extendible member. The body and the extendible member define a stroke length extending along a stroke axis, with the actuator mounted in the lifting assembly between two levers.
