Two lifting frames 10 are installed on the ground under the blocks (not shown in the drawing) of the trailer part of the tracklayer (not shown in the drawing). Cargo ropes are stocked (not indicated in the drawing) of lifting winches (not indicated in the drawing) on the corresponding blocks (not indicated in the drawing) on the longitudinal truss (not indicated in the drawing) and load-gripping frames 10, after which they are lifted by winches (not indicated in the drawing). indicated) to the upper position (not indicated in the drawing).

For control on the longitudinal farm (not indicated in the drawing), limiters 15 of the lifting height of the load-handling frames 10 and sensors 16 of the bending force of the rope (not indicated in the drawing) of the winch (not indicated in the drawing) are installed, limiting the maximum load capacity, and also excluding the winding of a weakened branch of the rope (not indicated in the drawing) on the winch drum (not indicated in the drawing). The operation of the sensor 16 is based on measuring the tensile force of the cargo rope branch (not indicated in the drawing) and depends on the mass of the lifted load (not indicated in the drawing).

For safe inspection and maintenance of elements and equipment in sections 1, 2 and 3 of the longitudinal truss (not indicated on the drawing), platforms (not indicated on the drawing) are organized with folding ladders (not indicated on the drawing) and handrails (not indicated on the drawing).

Transportation of the towed part of the tracklayer (not indicated on the drawing) along the rail tracks (not indicated on the drawing) without disassembly can be carried out using a traveling trolley (not indicated on the drawing).

The mechanism for straightening (not indicated on the drawing) used when laying links (not indicated on the drawing) of a railway track (not indicated on the drawing) in curves with a minimum radius of up to 400 m (not indicated on the drawing) is made with the possibility of rearrangement and hinged fastening ( not indicated on the drawing) both on the inner and outer cheeks of the rocker arms (not indicated on the drawing) connecting the supports 8 with the caterpillar bogies 9.

To expand the possibilities of using the trailer part of the tracklayer (not indicated in the drawing), the length and support width (by 800 mm) of the caterpillar trucks 9 have been increased.

In preparation for work, the trailer part of the tracklayer (not indicated in the drawing) is connected to the tractor 20. Dismantling the trailer part of the tracklayer (not indicated in the drawing) is carried out in the reverse order.

In the proposed trailer part of the tracklayer, the effect of simplifying the design and increasing its reliability is achieved through the use of folding, folding sections of the longitudinal truss, eyes when connecting the portal to the truss, adjusting the supports according to the overall width of the portal and installing swivel brackets, mounting platforms with folding ladders and handrails, placing lifting height limiters of load-handling frames and winch rope bending force sensors, use of inventory containers.

The proposed trailer part of the tracklayer can be used as part of a tractor tracklayer for laying and dismantling the railway track on single-track and double-track lines with a gauge of 1520 or 1435 mm with a link length of 12.5 m or 25 m on wooden or reinforced concrete sleepers and rails up to type R-65 inclusive with a total weight of up to 22 tons.

At the same time, the tractor tracklayer can be used when performing the tasks of building (restoring) railway lines with independent movement under its own power along the existing railway track or outside public roads. Over long distances, the trailer part of the tracklayer is transported disassembled on railway platforms or by road.
