Abstract: A system for allowing a wheeled truck to cooperate with a relatively stationary lift table assembly, in order to selectively raise the truck during various material handling operations. The lifting combination essentially comprises a vertically extendable lift table assembly which cooperates with a wheeled truck which can be selectively superposed upon the lift table assembly. The lift table includes a scissor jack linkwork, and can be easily positioned, as necessary, within a material handling space. The wheeled truck includes means to engage guideways on the lift table assembly, as the truck is wheeled thereover to its selective engagement position.
