Use of Simplified Jackknife Restraint Device Significantly Reduces the Hazard of Jackknifing 730642

A simple jackknife restraint device which is integrated with the vehicle's normal braking system controls against the hazard of jackknifing in tractor/trailer operations. The device operates in conjunction with the vehicle's braking system, and the braking action restrains the vehicle from articulating into a dangerous jackknife attitude.
The jackknife control mechanism, composed of four major parts, is described, and operation of the control is explained in terms of geometry of installation. Testing of the control is also discussed.
