ABSTRACT:
An improved self contained elevating table suitable for loading dock and the like load lifting operations. The platform is supported by at least one pair of scissor legs the opening of which is accelerated and amplified by a cylinder-operated toggle lever subassembly the opposite ends of which are pivotally connected between the outer end portion of one leg and a bracket mounted for movement with the other leg at a point spaced radially from the common midlength pivot access of the pair of legs. The roller-equipped pivot interconnecting the toggle lever and cylinder is offset from a line through the remotely positioned pivot axis of the cylinder and toggle subassembly, and this roller cooperates with a ramp or other constraint on the apparatus to accelerate and amplify initial opening of the scissor legs from the collapsed horizontal positions thereof.
