ABSTRACT:
A cleat for releasable clamped engagement to a continuous rubber track on a mobile construction unit for improving traction. The cleat includes (i) a body with downwardly extending, inwardly facing and laterally spaced end hooks, wherein at least one of the end hooks is laterally repositionable relative to the other end hook as between an open position and a closed position, (b) at least one projection extending upward from the body effective for biting engagement with a supporting surface, and (c) a manually operable repositioning assembly for reversibly driving the at least one laterally repositionable end hook towards the other end hook, whereby the body may be clamped onto a rubber track on a mobile construction unit.
