On the frame 1 are to conduct repairs two height-adjustable transversely of the machine spelaeogriphacea unit 4, one paleothermal and straightening unit 5 containing the actuators lifting and straightening, as well as managing these units reference system 6 leveling and straightening. The Central power unit 7 is used to drive all located on the machine actuators. To determine the actual position of the train path 3 is provided for rolling on the path of the measuring carriage 8 is connected between widely spaced apart rail-road trucks 2 through actuators with adjustable height and breadth of the machine frame 1 and for centering when installing on the road equipped with a device 9 for installation is shown in Fig. 2 and 3, the device 9 to install the tool frame on the railway consists of two (in their lower position reading) located above the rails and mirror relative to each other parts, of which for simplicity shows only the part situated above the left rail. This part of the device 9 has a carrier frame 11 fixedly connected with the tool frame 12 of the measuring trolley 8. Instrumental frame 12 by means of the actuators 13 and 14 move in height across device pivotally attached to the frame 1 of the machine is adjustable in relation to it and has wheels 15 with the flange provided for contact with the rails 16 of the path 3. Perpendicular to the longitudinal direction of the machine of the rotary plate 17 formed through two levers 18 parallelogram hinge connection pivotally attached to the base frame 11 and is adjustable relative thereto by means located on the support frame 11 and is designed as a spring-loaded power cylinder rotary actuator 19 in the transverse plane running perpendicularly relative to the plane of the path and in the transverse direction of the machine (see indicated in phantom lines upturned position on the lion the Ooty rotary plate 17 to limit its rotary movement still attached to the vertical fence 20 of the supporting frame 11.The lower passing is basically parallel to the plane of the path and the axis 21 of the wheel 15 with the flange end zone of the rotary plate 17 is made in the form of contact strips 22, consisting of two spaced stepped offset relative to each other along the height of sections 23 and located below the section 23 has a vertical stop 24 for contact with the side surface of the head 25 of the rail 16. The length of the sections 23 of the strap 22 is the result of a boom lift arc of the circle described by rail with a minimum arc radius, depending on the length of a chord of the circle formed by the spaced apart rail-road trucks 2. To fit to the head 25 of the rail 16 of the contact strip 22 has a bearing surface 26 of insulating material 27.
