What if the cable (wire rope) breaks?

In the extremely rare case that a cable were to break our mechanical slack cable brakes located on the chassis would immediately engage the rails and bring the car to an instantaneous stop.
For reference, Hill Hiker, Inc. uses a minimum of 3/8th in. dia. galvanized aircraft cable on our standard systems which is rated to 14,400 lbs of breaking strength. This is thicker and stronger than what most of our competitors use.
