METHOD OF CRANE-FREE TRANSFER AND TRANSPORTATION OF LARGE- SIZED AND LARGE-MASS ARTICLES TO AIRCRAFT PLATFORM AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 1999 - IPC

Abstract RU 2142390 C1

FIELD: mechanical engineering. SUBSTANCE: first cargo is transferred from aircraft to platform of trailer that includes power mechanism to lift and change height of platform and retractable supports to fix platform, cargo platform with two rows of roller fixtures attached underneath, guiding profiles of E-shaped cross-section with transverse beams of base and thrust wire. Members of cargo platform and cargo are secured with the aid of thrust wires with regard to each other and to platform of trailer and are transported to airport. Trailer is positioned along one axis with axis of aircraft, its platform and members of front cargo hatch of aircraft are leaned against screw props adjusted over height. Then article is lifted with the help of power mechanism of trailer to level of platform of vehicle-cargo hatch of aircraft and is fixed by means of retractable supports of trailer. Later platform of trailer is set with the use of screw props adjusted over height to one plane with members of front cargo hatch and cargo floor of aircraft at inclination angle of 2-3 deg with respect to horizontal line. Then track of guiding profiles of E- shaped cross-section is set on to members of front cargo hatch and cargo floor of aircraft equal to track on platform of trailer. Cargo platform with article is moved along guides into cargo compartment of aircraft with the aid of winches and tackle system. EFFECT: enhanced efficiency of transfer of cargoes. 2 cl, 8 dwg
