External traction device for endless tracks
A traction improvement device provides increased traction to a tracked vehicle. The traction improvement device has two opposing brackets that are connected to opposite edges or flanges of a track of a tracked vehicle. A chain extends between the brackets. At least one of the brackets is a tensioner bracket that is configured to adjust the tension of the chain. The tension adjustment provides tension to the chain extending between the brackets, securing the traction improvement device on the outer surface (or gripping surface) of the track.
1. A traction improvement device for a tracked vehicle, said device comprising:
two opposing brackets wherein a first of said opposing brackets comprises a tensioner bracket, wherein said opposing brackets are configured to be secured to opposing edges of a track of the tracked vehicle,
a chain extending between said opposing brackets and configured to span across a gripping surface of said track when said opposing brackets are secured to the opposing edges of said track; and
wherein said tensioner bracket comprising a tensioner connected to said tensioner bracket, wherein said tensioner is configured to increase tension on said chain to secure said traction improvement device to said track, wherein said tensioner comprises a bolt extending through a wall of said tensioner bracket; and
wherein each bracket has a bracket arm configured to extend along the opposite surface of the track from the chain.
2. The traction improvement device of claim 1 wherein a second bracket of said opposing brackets comprises a fixed bracket, wherein said chain is fixedly attached to said fixed bracket.
3. The traction improvement device of claim 1 , wherein at least one of said brackets comprises a U-shape.
4. The traction improvement device of claim 2 , wherein said fixed bracket comprises a U-shape.
5. The traction improvement device of claim 3 , wherein said tensioner bracket comprises the U-shape.
6. The traction improvement device of claim 1 wherein said bolt comprises a head positioned exterior to said wall from said chain, wherein a shank of said bolt is connected to a nut connected to said chain, wherein rotation of said bolt head causes rotation of said shaft in said nut causing adjustment of the tension in said chain.
7. The traction improvement device of claim 6 wherein said nut is welded to a link of said chain.
8. The traction improvement device of claim 1 , wherein said bolt comprises a first end attached to said chain, wherein a shank of said bolt extends away from said first end and through a wall of said tensioner bracket, wherein a nut is attached to said shank such that rotation of said nut adjusts tension on said chain.
9. The traction improvement device of claim 8 wherein said bolt comprises an eye bolt such that said first end of said bolt comprises an eye, wherein said eye is connected to said chain.
10. The traction improvement device of claim 2 wherein said chain is connected to said fixed bracket by a welded connection.
