Abstract: A transport frame and lifting apparatus for the transport of railroad wheel sets is disclosed. The transport frame is configured for mounting to a hauling flatbed, preferably a flat truck trailer bed hauled by a fifth wheel attached tractor. The frame includes an axle support surface, preferable paired beams, spaced at less than the inside wheel to wheel distance to receive and roll the wheel sets at the medial axles. The axle support surface is a distance above the flatbed so that the wheel sets when received at the axles have the wheel peripheral rail flanges clear the flatbed. Movement of the wheels to a storage position on the transport frame occurs by rolling the wheels on the medial axles to a storage position where peripheral tie-downs secure the wheels at their rims from movement. Upon arrival at a loading and/or unloading destination, a reciprocating lever arm assembly at one end of the transport frame effects loading and unloading of the wheel sets.

Abstract: A tire protector for reducing wear on the tires of heavy vehicles consisting of two or more parallel rows of spaced apart chain links. These links are joined by couplings members and consist of metal bars or wires which are bent so that they encircle each two chain links and that the ends of the bars or wires overlap side by side. These overlapping ends are positioned to face upwardly and flat when the protector is mounted to a tire. As a result only a relatively small area comes continually with contact with the ground and is thus exposed to wear and tear. This contacting area is strongly enforced due to the thickness of the sidewise overlapping ends, as a result, parts of the protector, such as the chain links and the bars or wires which form the coupling member, can be made fairly thin as they are not exposed to considerable wear thereby reducing the overall cost of producing the protector and also extending its lifetime.
