FACILITY FOR AIRCRAFT EVACUATION

摘要

FIELD: ground servicing of aircraft; aircraft transportation facilities. ^ SUBSTANCE: proposed facility includes tractor with trolley made in form of frame and secured to it. Bearer frame is provided with movable frame secured on it and provided with fork-shaped grip engageable with nose undercarriage leg. Trolley is provided with hydraulic power cylinder for raising and lowering the movable frame. Hydraulic power cylinder is located between stops mounted on bearer frame of trolley and movable frame. Facility is provided with movable bush mounted on said hydraulic power cylinder and fixed with metal pin when rod of hydraulic power cylinder reaches thrust surface of movable bush. Proposed facility makes it possible to tow aircraft with damaged tire and at absence of wheels of nose struts. When tires are mounted on trolley instead of wheel, this facility makes it possible to tow aircraft over low-tenacity soil possessing high rolling resistance coefficient. ^ EFFECT: enhanced tractive and road-holding capacity of tractor. ^ 4 dwg
