FIELD OF THE INVENTION The invention relates to lifting and transport machinery, in particular, to devices for lifting column-type apparatuses with two lifting means.

A device for lifting column-type devices with two lifting means is known, comprising a carrier beam with columns mounted on it, to which a carrier and auxiliary flexible elements are attached, covering the device in a transverse plane and mounted on a supporting structure, and a slinging unit connected by flexible rods to the supporting one part of the apparatus 1.

However, the known device cannot be used for lifting devices of different diameters.

The purpose of the invention is to expand the technological capabilities of the device by providing lifting devices of different diameters.

This goal is achieved in that in the device the support beam is made with a series of holes at both ends for fastening the posts, which are made of separate parts connected by flange connections.

and are installed with the possibility of rotation with respect to the bearing shoulder., the ends of which are equipped with struts, which are hingedly jointly with one end to the specified beam, and the other - with the upper parts of the uprights, on

5 of which are hinged reinforcement knot slinging.

FIG. 1 shows a device for lifting column-type vehicles with two jib cranes, a general view; in fig. 2 the same, side view.

A device for lifting column-type vehicles with two lifting means comprises a carrier beam 1, at the ends of which two arm supports are hinged, consisting of racks 2 of variable

5 heights with flange joints 3 and struts 4. Racks and struts are mounted on carrier beam 1 by means of axles 5 inserted into holes 6 made in carrier beam 1. The distance between brackets is chosen depending on the diameter of the lifted device 7. Steel carrier tape 8, which serves to support the apparatus, is hingedly attached to the brackets. The tops of the uprights of the 2 arms are provided with axles 9, to which are mounted the earrings 10 with axes 11 for slinging the device onto the hooks 12 of the lifting means. Rope trays 13 are attached to axis 9, connecting the slinging device to the axles of the lugs 14 welded to the support part of the apparatus 7. The device is fastened to the device with the help of hoams 15., „„ The device works as follows: Apparatus 7 is laid out on temporary supports . In place of slinging under the apparatus body, beam 1 is also placed on temporary supports. Brackets are attached to the beam at a distance corresponding to the diameter of the apparatus, to which the carrier tape 8 is pivotally suspended, after which beam 1 is lifted with a jack to The apparatus body, in such a position, is attached to the apparatus by means of two clamps 1b. Two cable rods 13 are attached and slightly tensioned with lever winches. At the beginning of the ascent, when the apparatus is horizontal, the carrier tape 8, the brackets and the beam 1 experience the maximum design loads from the mass of the lifted apparatus. The ropes in this position are not loaded. As the apparatus rises, the loads are redistributed, the tension of the carrier tape decreases, and the tension of the cable trays r increases. The maximum tension value t g, equal to the mass of the apparatus, distributed over two rods, occurs when the apparatus is in a vertical position, when the carrier tape, the brackets and the beam are unloaded. The application of the proposed device allows to ensure reliable lifting of apparatuses of various diameters, which, in turn, eliminates the need to have some devices for lifting devices of various diameters, i.e. the metal diffusion and the cost of manufacturing additional devices are reduced. Claims An apparatus for lifting column-type apparatuses by two lifting means, comprising a carrier beam with columns mounted on it, to which a carrier and auxiliary flexible elements are attached, covering the apparatus in a transverse plane and fixed to the supporting structure, and a slinging assembly connected by flexible t gami with a supporting part of the apparatus, characterized in that, in order to expand technological capabilities by providing lifting apparatus of various diameters, the carrier beam is made and with a series of holes at both ends for fastening the posts, which are made of separate parts connected by flange joints, and are mounted rotatably with respect to the carrier beam, the ends of which are equipped with struts hinged by one ends to said beam, and the others with the upper parts of the uprights on which the slinging nodes are hinged.
