Abstract: A highly durable elastic crawler with a tensile cord having both ends thereof overlapped mutually in a crawler body thus being circumferentially wound around the crawler is provided. An elastic crawler includes; a crawler body including an endless belt-like elastic body; metal cores embedded in the crawler body, each of the metal cores including vanes and arranged at predetermined intervals circumferentially; and tensile cords transversely arranged, wound around the outer circumference side of the vanes, and embedded in the crawler body while vicinity portions of both ends of the tensile cords are overlapped mutually. An inner circumference side end is arranged at an outer circumference side of any one of the vanes. The distance between the vicinity portion of the inner circumference side end and the outer circumference side portion of the tensile cord overlapped there is increased from the vicinity portion toward the inner circumference side end.

Abstract: An enhanced traction device for use with a vehicle having dual tandem wheels includes a series of generally parallel track pads, each track pad having an alignment portion and a traction portion defining first and second ends. Each traction portion includes an inner surface for contacting the vehicle wheels and an outer surface for contacting ground. Each alignment portion extends away from a respective traction portion outer surface and is configured to pass between the dual wheels. The alignment portions maintain proper positioning of the track pads upon the dual tandem wheels of the vehicle. The traction device further includes a first chain coupled to each respective track pad first end for maintaining a predetermined spacing between said track pad first ends. Similarly, the traction device includes a second chain coupled to each track pad second end for maintaining a predetermined spacing between the track pad second ends.

Abstract: The present invention provides a rubber crawler used for a running unit of a vehicle for farm work, or civil engineering/construction work. Core bars are embedded with a constant spacing in a lengthwise direction of the rubber crawler without steel cords. A closed-loop opening is formed in each of left and right wing portions, which are of a rubber embedding portion of a core bar. The edge portions of the closed-loop openings of the adjacent core bars are fitted into fitting portions with a coupling body including the fitting portions in which both ends are opened in an inward direction. The edge portions are connected with each other at the coupling body to make the coupling body as a counter-tensile material.
