Abstract

The embodiments of the invention are directed to a device and method for moving a load from a first height at a first location to a second height at a second location. The device includes a platform having a top surface and a bottom surface, and opposed guide members extending from the bottom surface of the platform and oriented along and parallel to the length of the platform. The device further includes a support member slidably engaged with the guide members, the support member capable of extending beyond the length of the platform or retracting beneath the platform. The device further includes a lift assembly having a frame and a controller. The frame is pivotably secured to the lower surface of the support member. The frame has a pair of parallel, opposed, leg assemblies where the height of the leg assembly is adjustable, and the controller controls the height of the leg assemblies.

Dependent claims

A device for moving a load comprising:

a platform having a top surface and a bottom surface;
two opposing guide members extending from the bottom surface of the platform and oriented along and parallel to the length of the platform;
a support member moveably engaged with each of the two opposing guide members, the support member capable of extending beyond the length of the platform and retracting beneath the platform;
a lift assembly comprising a frame and a controller, the frame pivotably secured at one end to the support member, the frame having a pair of parallel, opposed, leg assemblies where the height of the leg assembly is adjustable from a fully extended position at a first height to a fully retracted position at a second height, and the controller adjusts the height of the leg assemblies;
and
rotational members rotatably mounted to the platform wherein the rotational members extend below the support member and the lift assembly when the support member and lift assembly are in the fully retracted position beneath the bottom surface of the platform.
