摘要：A method and apparatus for transferring a load (L) to and from a load

supporting platform (100) having a first end (110) pivotally coupled toward the first endof a main frame (200) with a support surface for supporting the platform (100) in asubstantially level position. The platform (100) is pivotally raisable from the supportsurface of the main frame (200) to a raised position for discharging and accepting theload (L) either manually or by an actuatable member (300). A damping member (400)interconnects the platform (100) and the main frame (200) wherein the damping member(400) progressively increases resistance on the load bearing platform (100) as theplatform moves from the raised position toward the support surface of the main frame(200) to reduce any impact on the load (L). The platform (100) includes a lower frame(130) and a cover (140) biased away from the lower frame (130) by a plurality of springmembers (150) wherein the cover (140) is movable toward the lower frame (130) by theload (L) disposed on a support surface of the cover (140) to actuate a load sensor (160),which indicates the presence of the load (L). A first pair of motor driven wheels (250) iscoupled to the first end of the main frame (100) to drive the apparatus along an

operating surface (T), and a second pair of wheels (260) is coupled to a opposing sides of

a pivoting member to compensate for unevenness in the operating surface (T).
