The travel nut on LA500DC and LA500DCS gate operators may break when excessive force is applied to the gate such as being struck from a vehicle.
The travel nut can be identified as the white plastic nut that attaches to the internal lead screw of the arm.
The symptom of this problem is that the trolley assembly slides back and forth along the guide slots without mechanical restraint.
