Abstract
The invention consists of an improvement in the art of arresting a moving body through the use of steel cables that elongate to absorb the kinetic energy of the body. The improvement comprises a sleeve which surrounds the cables, protecting them from chafing and providing a failsafe energy absorbing system should the cables fail.
Claims9
A device for arresting the velocity of a moving object comprising:
- energy absorbing means for absorbing the kinetic energy of a moving object by elongating, said energy absorbing means being attached at opposite ends to an anchor means;
- and
- sleeve means loosely surrounding said energy absorbing means at least in the non-elongated condition of said energy absorbing means for protecting said energy absorbing means from chafing, and for providing a failsafe in case of failure of said energy absorbing means, said sleeve means being anchored to said anchor means at ends corresponding to ends of said energy absorbing means under all conditions of operation.
