This technical solution is made as the closest analogue of the present invention.

The mobile lifting complex of the closest analogue contains loading and unloading devices in the form of two cantilever slewing cranes, each of which is mounted on a base plate mounted on guides of a freight railway platform and equipped with a movement mechanism. The movement mechanism of each base plate interacts with a cable system that provides movement of the base plate with a jib crane on guides from one side of the cargo railway platform to the opposite side. In addition, the mobile lifting complex of the closest analogue contains two freight railway platforms mounted on undercarriages.

The equipment of the closest analogue requires constant, volumetric maintenance during operation.

The present invention is based on the solution of a problem that allows to simplify and improve the design of overhaul volatiles, increase reliability, increase the operating life of jib cranes and the entire structure as a whole and reduce operating costs.

The technical result of the present invention is to simplify operational equipment and use component devices with increased power parameters, to reduce the time of work and the complexity of maintenance, maintainability and operation of overhaul volatiles in difficult climatic and industrial conditions.

According to the invention, this problem is solved due to the fact that the overhead flyback contains a railway platform, two cantilever slewing cranes, end shields and a power plant with switching equipment.

The railway platform is made double, on each of the parts of which there is a jib crane.

A jib crane is mounted on a support frame.

The supporting frame contains a movable frame and movable beams with movement mechanisms.

The movable beams are made with guides and are associated with a movable frame.

The movable frame has the ability to mount a jib crane using a slewing rotary device and move it along the guides from one side of the railway platform to the opposite side for carrying out bilateral loading and unloading operations with the possibility of smooth and parallel movement of the movable beams to the required fixed position through a single kinematic unit .

A single kinematic unit includes a mechanism for moving the movable frame and a rotation mechanism of the cantilever slewing crane.

The applicant has not identified sources containing information about technical solutions identical to the present invention, which allows us to conclude that it meets the criterion of "novelty."

Due to the implementation of the distinguishing features of the invention (in conjunction with the features indicated in the restrictive part of the formula), important new properties of the object are achieved.

The implementation of the railway platform double in the form of one section simplifies the design of overhead volatiles.

The implementation of the supporting frame for the cantilever slewing crane with movable beams made with guides and moving mechanisms, and movable frames will improve the design of the overhead flyback.

The implementation of the movable frame with the possibility of mounting the cantilever slewing crane using a slewing rotary device and moving it along the guides of the movable beams from one side of the railway platform to the opposite side increases the reliability of the overhead volatile.

The implementation of the movable frame with a single kinematic node, including the mechanism of its movement and the rotation mechanism of the cantilever slewing crane, does not require constant, volumetric maintenance during operation, which increases the operating life of the jib cranes and the entire structure as a whole and reduces operating costs.

The applicant is not aware of any publications that would contain information on the influence of the distinguishing features of the invention on the achieved technical result. In this regard, according to the applicant, it can be concluded that the claimed technical solutions meet the criterion of "inventive step".
