The device is equipped with a trailer 19 (figure 1, 2), made with the possibility of installation and fastening on it flyover 1 (figure 1, 2), stand 20 (figure 1, 6, 7) under the ramp, made with the possibility of adjusting its height and is also equipped with a transitional ladder 21 (Fig. 1, 2, 11), made with the possibility of installing on it the guides 4 (Figs. 1-4) in the same plane with the guides 4 (Figs. 1-4) installed on the loading platform 3 (FIGS. 1, 2) of the trestle 1 (Figs. 1, 2), on the one hand, and guides 4 (Figs. 1–4), mounted on the ramp and floor 22 (Figs. 1, 2) of the cargo compartment 23 ( figure 1) of a Paraty, on the other hand. The guides 4 (Figs. 1-4) of the W-shaped profile are fixed on the uprights 8 (Figs. 3-5) and struts 9 (Figs. 3-5) of the overpass by means of the bolts 24 (Figs. 3) and locking pins 25 (Figs. 3), inserted into the holes of the docking nodes 26 (Figs. 3, 4) of the upper part of the struts (Figs. 3, 4), and also fixed by means of bolts 24 (Fig. 3) and locking pins 25 (Fig. 3), inserted into the holes of the fork brackets 13 (Figs. 3, 4) mounted in pairs along the edges on its lower surface of the guides 4 (Figs. 1-4). The guides 4 (Fig.1-4) are installed in two rows in a horizontal plane on the loading platform 3 (Fig.1, 2) of the trestle 1 (Fig.1, 2), transition ladder 21 (Fig.1, 2, 11), ramp and floor 22 (figure 1, 2) of the cargo compartment 23 (figure 1) of the aircraft. Racks 8 (Fig.3-5) and inclined struts 9 (Fig.3-5) are fixed by means of bolts 24 (Fig.3) and locking pins 25 (Fig.3), inserted into the holes of the docking nodes 26 (Fig.3- 5) the lower part of the struts 8 (Fig.3-5) and inclined struts 9 (Fig.3-5) with brackets 27 (Fig.3, 4) mounted on the upper surface of the transverse power beams 14 (Fig.3, 4) previous sections 5 (Fig.1-3). The support 20 (Fig.6, 7) under the ramp contains two bearing zones and is made of a frame structure including a base 28 (Fig.4) having the shape of a trihedral prism, in which one bearing zone is made in the form of an upper power belt 29, 30 (Fig .6, 7) and the lower power belt 31 (Fig. 6, 7) and three supporting tubular posts 32 (Fig. 6, 7) having bottom disk supports 33 (Fig. 6, 7) and adjustable screw supports 34 from above (6, 7) for fastening the tool tray 35 (6, 7), and the other bearing area is made in the form of an adjustable screw support 34 (6, 7) for fastening the disk support 3 3 (Fig.6, 7) under the heel of the ramp.

The upper power belt 29, 30 (Fig.6, 7) and the lower power belt 31 (Fig.6, 7) are made of pipes, while the pipes between the uprights 32 (Fig.6, 7) of the removable tool tray 35 (Fig.6, 7) and a stand 32 (Fig.6, 7) with a disk support 33 (Fig.6, 7) under the heel of the ramp are pivotally fixed and after unlocking they make it possible to fold the base 28 (Fig.4) in one plane. The removable tool tray 35 (Fig. 6, 7) and the disk support 33 (Fig. 6, 7) are attached to the adjustable screw supports 34 (Fig. 6, 7) using bolts 24 (Fig. 6, 7). To strengthen the structure and ensure its strength, the transition ladder 21 (Figs. 1, 2, 11) is made in the form of a segment of the guide 4 (Figs. 1-4) of the W-shaped profile 4 (Figs. 1-4), attached from below to the T-section profile (not shown in the drawing).

The operation of the device for loading and unloading mono-cargo and wheeled vehicles in aircraft.

Before loading mono-cargo and wheeled vehicles, an aircraft such as the heavy transport aircraft IL-76 is installed on the concrete strip of the airfield. The ramp of the aircraft is in the open position and is installed horizontally. Adjustable stand 20 under the ramp is unloaded from the cargo compartment 23 of the aircraft, is transferred to the transport position. The removable cradle 35 of the stand 20 is mounted on the screw supports 34, respectively, previously lowered to the lower position. The stand 20 is pushed under the ramp of the aircraft until the abutment points on the ramp are combined with the removable cradle 35 and the disk support 33 of the stand 20. Using the screw supports 34, the removable cradle 35 and the disk support 33 are brought into contact with the ramp, providing a clearance-free support. Section 5 of the transitional overpass 1 is unloaded from the aircraft and transferred from the transport to the working position. Trailer 19 with a load is installed along the axis of the aircraft and approaches backward to it at a distance of 20-30 m. Using a crane with a lifting capacity of at least 50 tons, it is removed from trailer 19 and installed on the ground. Sections of the transitional overpass 1 are mounted on the trailer 19 in two parallel rows at a distance corresponding to the track of the loading wheels, and are connected in each row by plates 6, and between the rows by docking units 7, made in the form of rods. On load carriers - guides 4 of the transitional overpass 1, load platforms with a running gear or roller beams are installed on which the cargo is installed by a crane. Trailer 19 in reverse feeds to the ramp slice, not reaching 1 m. Between the ramp and the typical section 5 of the transitional overpass 1 laid on it and the floor 22 of the transitional ramp 1, transitional ramps 21 are installed, after which the device is ready for loading a mono-load, which using a winch or otherwise method rolls into the cargo compartment 23 of the aircraft. The unloading of a single cargo at the destination aerodrome is carried out in the reverse order. The design of the device allows loading, unloading and transportation of a mono-cargo weighing 50 tons and wheeled vehicles in aircraft such as the heavy transport aircraft IL-76 by combining the loading areas of the aircraft and trailer 19 with cargo, facilitating the operation of the ramp with great reliability and safety.
