Crushers are used in underground mining to reduce all material to a safe size to protect conveyor belting. Traditional shear pins required frequent replacement in many mines. The result was significant down time and lost production.


Several torque limiters had been tried and proved inadequate. We developed a special assembly including high misalignment couplings. This rugged design had no adjustment and no disconnect.

Proper sizing protected the equipment while eliminating down time. Over all crusher efficiency went up.

If you have a difficult overload problem, we will see if we can develop just the protection you need without lost production.
