FREIGHT TRAILER Russian patent published in 1997 - IPC

FIELD: automotive industry; freight trailers. SUBSTANCE: wire rope is pulled up by winches to compress shock absorbers, i.e. to load them, thus reducing dynamic loads. With trailer loaded, tension of wire rope is reduced by unlocking the winch. Shock absorbers 11 in this case are compressed by load in body. When high loads are carried by trailer, tipping forces appear at moving up or down the slope. To increase stability, right-hand or left-hand shock absorber 11 is lifted by operating right-hand or left-hand winch. EFFECT: increased reliability and longevity by reducing dynamic loads appearing in empty trailer in motion. 3 dwg
