Abstract: In a broad aspect, the invention is a kit used for mobilizing heavy objects such as items of furniture, boxes, appliances, etc. The apparatus is based on a plurality of rigid support structures, or “shoes”, which are to be inserted under the corners of the item to be moved. Those support structures carry longitudinal and transverse conduits which can accept long, rigid link members, such as rods. The rods or link members are fastened to each other by means of screw-like threads, and are finally fastened to the conduits in the shoes. The net result is the formation of a rigid “cage” around the item to be moved. Each of the shoes is equipped with a wheel that is originally elevated above the ground plane. By lifting the rigid cage slightly on each side, the wheels will drop vertically and remain engaged. The cage, carrying the heavy object, can then be moved effortlessly.
