Arens Q36 Series control mechanism uses a "strap-shoe locking mechanism" which has four main elements: a primary input lever, an actuating or output lever, a strap-shoe / locking pin assembly and a stationary quadrant.The strap shoe assembly is spring-loaded to the unlocked position until a load is applied to the output, causing the strap-shoe to rotate about the locking pivot, forcing a locking pin to grip the quadrant. The gripping force caused by a pin on the underside of the quadrant and the strap-shoe locks the control. Two locking pins enable the control to lock with an output load from either direction.
