Abstract: An endless tread of the single-pin type which includes a rubber-supported bolt in a tread member and cog-like connecting locations fastening the bolt to the tread member. The bolt incorporates rubber rings vulcanized thereon, and is pressable into a transverse bore in the tread member. Clamping lugs are slidable onto the bolt and clamping the latter to form a detachable connection to an adjoining tread member.

Abstract: A wire cable chain in which spaced links are connected by wire cables. Resilient cushion structures are provided extending between each pair of adjacent links. Each link has a transverse groove on the cushion structure side and each cushion structure has a metal flange at each of the fore and aft edges insertable in one end of said groove and slidable in the groove into fully inserted position. An abutment stops each cushion structure in inserted position in the chain and cams on the cushion structure cooperate with abutment shoulders on the chain links to lock each cushion structure in inserted position.

Abstract: A divisible guiding and connector arrangement for track laying chains of track laying vehicles, in which tubular bodies surrounding sections of successive chain bolts between the pertaining chain links are vulcanized onto the aforementioned chain bolt sections. The tubular bodies are firmly interconnected by connecting means, e.g., by screw means or by clamping elements interconnected by screw means.

Abstract: A twin track laying chain, in which the chain bodies provided with guiding mandrels are interconnected by connectors adapted respectively to be received by the tooth spaces of toothed gear rings respectively associated with the two chains of the twin chain. The two chains are so offset relative to each other in the longitudinal direction of the two chains that the teeth of one of the toothed gear rings are in alignment with the tooth spaces of the other one of the toothed gear rings.
