Abstract:
A patient support has caster devices supporting a frame for movement in relation to a supporting surface. A lift supports an auxiliary wheel in relation to the frame. A shaft may be rotatable to drive the lift to move the auxiliary wheel between a deployed position and a retracted position. The shaft may rotate to control deployment and retraction of the auxiliary wheel. A sensor may control deployment and retraction of the auxiliary wheel. An element may provide a dampening effect when the auxiliary wheel encounters a raised surface and urge the auxiliary wheel into contact with the supporting surface when the auxiliary wheel encounters a lowered surface.
