    • 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.
    • 患者支架具有支撑相对于支撑表面运动的框架的脚轮装置。 升降机相对于框架支撑辅助轮。 轴可以是可旋转的以驱动升降机以在展开位置和缩回位置之间移动辅助轮。 轴可以旋转以控制辅助轮的展开和缩回。 传感器可以控制辅助轮的展开和缩回。 当辅助轮遇到升高的表面时,元件可以提供阻尼效果,并且当辅助轮遇到下降的表面时,促使辅助轮与支撑表面接触。
