  • Patent number: 9862436
    Abstract: A device 1 for use with a continuous track 3 of a tracked vehicle to enhance the traction of the vehicle. The device 1 has an elongate body 5 having a ground contacting surface 6 and a releasable bracket 7 for releasably securing the elongate body 5 to the continuous track 3. The releasable bracket 7 has a bracket body 11, a first clamping member 13, a second clamping member 15 extending at an angle relative to the first clamping member, and a fastener 17. The bracket is arranged such that fastening the fastener 17 causes the second clamping member 15 to draw the first clamping member 13 towards the elongate body 5 to releasably secure the elongate body 5 to the continuous track 3. The device has one or more ground engaging features 39. A kit of parts is also described.

  • Patent number: 5944395
    Abstract: In the case of a connector endless track with travelling pad, the invention aims to guarantee a long service life for the travelling pads (1). The load-bearing surface of the travelling pad (1) on the carriageway is reduced by the engagement of a tooth (25) of a drive ring (26) into a tube body (5) of the connector endless track. In order to provide a compensation effect here the travelling pad (1) is extended in a direction towards the opening (3) and covers at least a portion (2) of the surface region of the opening (3) for the engagement of a drive ring (26).
