FIELD: aeronautical engineering; cargo loading/unloading devices; shipbuilding and other fields. ^ SUBSTANCE: proposed device includes trestle 1 mounted on trailer 19, support 20 for ramp 21 which is adjustable in height and ladder 22. Trestle body is made from standard sections mounted in two parallel rows and interconnected in rows by means of coupling units. Each section of trestle body is of frame construction; each section includes upper load-bearing belt secured on struts for forming loading platform and lower load-bearing belt and screw supports adjustable in height. Trestle is collapsible in construction for change of distance between rows of sections depending on track of wheeled equipment and for change of length and height of trestle due to change of number and height of standard sections. Guides are made in form of E-shaped profiles received by slots of roller devices and mounted on one plane on loading platform of trestle, ramp and floor of cargo cabin of flying vehicle. ^ EFFECT: enhanced efficiency of loading/unloading procedure. ^ 3 cl, 11 dwg |
