Torque Limiter

This adjustable, torque limiter can be used with any of our electric operator models that have a worm gear reducer as primary reduction system. It consists of a steel hub with two 4" diameter clutch plates, A50B23, or 60B23 sprockets, two 4" diameter asbestos fiber friction discs, and spring washer with pressure cup. Holding force is from 25 lbs. to 1500 lbs. Can be adjusted in the field as required depending on door weight. Torque limiter will protect door/gate and operator in case of obstruction. Synchronized limit drive assembly will not go out-of-adjustment when torque limiter is activated.
