CARRIER FOR LARGE SIZE LOADS SUCH AS AUTOMOBILES Russian patent published in 2000 - IPC

FIELD: transport engineering. SUBSTANCE: proposed carrier has support frame with movable ramp 3 mounted on chassis 1, ramp lowering device, ramp lifting device including winch mounted on ramp with wire ropes wound on winch drum in opposite directions and coupled with ramp and support frame through system of sheaves, device for pulling load onto ramp and ramp locking device. Stationary members of two wire rope length change and tension compensators with free ends of wire ropes secured on spring-loaded movable members of compensators are mounted on support frame. One of sheaves of ramp lowering device is secured on ramp, and the other is coupled with vehicle chassis. Load pulling device is mounted on ramp. Diameter of wire rope in ramp lifting device exceeds diameter of wire rope in ramp lowering device. Drum of which of ramp lifting device is made stepped, with diameter of winch drum part designed for winding-on ramp lifting device wire rope being smaller than diameter of winch drum part designed for winding-on ramp lowering device wire rope. EFFECT: simplified design. 9 cl, 13 dwg
