Abstract:
A traction device to engage a track of a tracked vehicle includes spaced apart longitudinal ribs and spaced apart transverse ribs forming a matrix, with at least one longitudinal rib having first gripping elements spaced apart to engage a track of a vehicle having lugs spaced at a first pitch and at least one other longitudinal rib having second gripping elements spaced apart to engage a track of a vehicle having lugs spaced at a second pitch. A number of third gripping elements are arranged across a width of each of the transverse ribs, and the transverse ribs are spaced to engage a track of a vehicle having lugs spaced at a third pitch.
