The drive car has vertical uprights 39 with damping devices 40 based on rubber 41 and steel plates 42, brackets with bearing pads 43, catchers 44 with rollers 45, retainer 46 in position of the crosshead. Item 47 is conditional.

In the initial position, the auto-operator 2 with the carriage 10 is in the upper position in the row of bathtubs of the 1st line outside the gauge of the rail carriage 5, the inventory yoke 3 is in the horizontal position. The drive trolley is located in the loading area of the product, the load to be serviced by the lifting device 6, the 2-cantilever pipes 32 of the crosshead are in a vertical position, perpendicular to the horizontal plane.

Sliders lodgements 36 are oriented vertically and fixed. The yoke is held, in the initial position by the latch 46. The product 47 suspended on the load-lifting device 6 on the cables fixed in the technological openings of the product is fed to the trolley and lowers until it comes into contact with the sliders 36. The teddy edge of the product after aligning the slide blocks with the technological holes The mi is secured with locking fingers. The product is released from the lifting device cables. Technological power, supported by pins 31 on rollers 45 of catchers 44 of racks 39 of the carriage, is moved along the axial tank 30 and rotated 90 until the supports 33 of the traverse with the supporting platforms of the carts racks. In this position, the process rod is again locked with latch 46.

The tubular rods 35 are set at an equidistantly free edge of the product, moving in the movable assemblies 34 and twisting in the hinges. Slider locks with springs 37 are coordinated with respect to technological

the holes of the product are fixed in them by springs. By screwing in the clamping bolts, the springs are stretched and thus the product is fastened to the pipes and bars of the process rod. The electric drive of the rail car follows the bath line up to the stop 48, after which the carriage drive is switched off and the brake is applied to the traveling wheels.

The operator 2 moves along the line of the baths and is positioned above the rail carriage. The lift drive 9, v lowers the carriage 10 of the auto-operator by switching from the cruising speed to the set speed. The actuator 9, made on the base of a direct current electric motor, has a wide range of its control in terms of the speed of rotation and, accordingly, in the speed of lifting the carriage.

The tapered pins 38 of the technological rod are inserted into the bushings 26 of the traverse inventory. The vertical movement of the carriage at the set speed occurs until the moment when the limit switch is triggered and the lift drive is stopped. This ensures the alignment of the inventory traverse and the technological bar along the conical pin and the sleeves. The locking pins are made by the clips 27 by means of the t g 28, brought into translational motion by the threaded flywheel 29.

In order to avoid dynamic loads, when damping the cross arms, damping devices 40 are provided on the racks 39 of the railcar.
