The invention relates to the construction and can be used in the repair and construction works.

The purpose of the invention is to mechanize the supply of cargo to the floor and increase safety.

Fig. 1 shows a diagram of the delivery of cargo into the window openings of a building when the device is vertically moved, side view; FIG. 2 shows a device at the moment of cargo delivery to a building through window openings, side view; Fig, 3 shows the device, general view Fig, 4 - fixing the load on the carriage; in fig. 5 - the same, with openings in the container with a load (option); in fig. 6 is a fragment of a notch at the end of the guide with carriage rollers.

The device for loading cargo into the window opening of the building contains a frame 1 with guides 2, to the ends of which two shoulders 3 are attached with counterweights 4. The guides together with two shoulders levers, inclined rods 5 and rods 6 form articulated parallelograms. Along the guides 2, a freight carriage moves in the form of a U-shaped frame 7, to the cross-bar of which a rigid three-linkage 8 is rigidly attached, the two arms 9 of which are arranged in a horizontal plane and at the ends have casing 10 1e cables 11. The third shoulder 12 is located in a vertical plane and at its upper end there is a slot 13 for hanging on the hook 14 of a lifting mechanism, and a curvilinear ha 15 is rigidly attached to the second end, which is rigidly connected to the load carriage . On

the ends of the frame 7 of the cargo carriage are arranged in a pair of rollers 16, through the through holes 17 of which the clamps in the form of fingers 18 are missed. The position of the frame 1 is fixed by vertical length stops 19 which are adjustable in length 19. A bracket 20 is attached to the roof of the building cables 11, passed through the clips 10 of the three-linkage 8 and equipped with a counterweight 22 and bolts 23. Through the bypass blocks 24 mounted on the console 21, the cargo rope 25 passes through the winch 26. On the hook 14 of the cargo rope is suspended by means of 13 8 trehzvennik communication.

The device works as follows.

The frames 1 are set obliquely on the floors so that their guides 2 with double-arm levers 3 are located on the window openings 27, and the rest part - on the floor slab 28. In this position, the frame 1 is fixed

 adjustable length vertical stops 19.

The gripping fingers 18 of the loading trolley are driven into the openings of the container 29, then with the aid of the winch 26,

5 of the cargo rope 25, the three-bolt 8, the curved rod 15 and the cargo carriage / container with cargo are raised to the required floor to the level of the exposed frame. The two shoulders levers 3 in this case are due to the counterweights 4 in a vertical position and do not prevent the movement of the container.

By rotating the interconnected rods 6 of the hinge parallelogram, they change its projection, while the two shoulders levers 3 rotate to align with the guides of the 2 frames. After that, the freight carriage is lowered with the help of rollers 16 onto these levers, followed by a congress along them, and then along guide rails 2 inside the building under the action of the force of its own weight. In this case, the container is lowered either onto the floor covering 28, or to the container carrier.
