Abstract
A method and apparatus for transferring a load to and from a load supporting platform having a first end pivotally coupled at a first end of a main frame having a support surface for supporting the platform in a substantially level position. The platform is pivotally raisable, from the support surface of the main frame to a raised position for discharging and accepting a load, either manually or by an actuatable member. A damping member interconnects the platform and the main frame wherein the damping member progressively increases resistance on the load bearing platform as the platform moves from the raised position toward the support surface of the main frame to reduce any impact on the load. The platform includes a lower frame and a cover biased away from the lower frame by a plurality of spring members wherein the cover is movable toward the lower frame by a load disposed on a support surface of the cover to actuate a load sensor, which indicates the presence of the load. A first pair of motor driven wheels is coupled to the first end of the main frame to drive the apparatus along an operating surface, and a second pair of wheels is coupled to opposite sides of a pivoting member to compensate for unevenness in the operating surface.
