Optimize loading dock safety by adding GMR Power Safety Chocks to your facility. For new or retrofitted applications, GMR Power Chock systems will provide years of trouble-free operation with virtually no maintenance. The Power chock system DOES NOT rely on the ICC bumper on the trailer to secure the vehicle against unscheduled departures while loading or unloading product; but rather a heavy-duty chock in conjunction with a ground plate, laser detection, alarm and light package that provides superior communication on both sides of the dock door. The GMR System is frequently interlocked with dock leveler controls in order to ensure that proper safety protocol is being performed.
