ABSTRACT:
A load control link for limiting maximum dynamic loads in and preventing overstressing of tension members by absorbing some of the energy which causes such loads. The load control link comprises a cylindrical housing, a metal sleeve mounted over a shaft within the housing and a cutting collar mounted at one end of the housing and around the sleeve. The inside radius of the cutting collar is slightly less than the outside radius of the sleeve, and is shaped as a cutting edge. The load control link is connected in series with a tension carrying member, with the end of the shaft which extends through the cutting sleeve connected at one end, and the opposite end of the housing connected at the other end. As the tension load on the control link increases, the shaft tends to be withdrawn from the housing causing metal to be cut from the surface of the sleeve by the cutting collar. The shaft remains stationary in the housing as long as the tension load remains lower than that required to cut metal. When the load is reached cutting begins and the shaft withdraws from the housing. Energy is absorbed by the metal cutting action, thereby providing control of the maximum load and preventing overstressing from occurring.
