The Tuff Limiter Clamps are engineered to provide a SAFE efficient way of clamping, fitting and removing Two Piece Lock Rings from OTR Wheel Rims used on Mine Sites. During fitting or removing, the Limiter Clamp fixes the opening distance making the assembly rigid by stopping any twist and safer to handle. Their unique design protects all parts of the clamping system with no exposed threads, making them easy to separate after extended periods of operation in the most severe Mine Site conditions.
