    A cable mover has a generally stationary support, a tube centered on an axis and having a pair of axially opposite ends, a swivel joint carrying the tube on the support and permitting the tube to move only nonaxially thereon, and respective axially double-acting actuators carried on the tube ends. Respective double-acting grippers are carried on the actuators. The cable axially traverses the grippers, actuators, and tube. The grippers each have two sets of wedge jaws engageable with the cable, one of the sets of each gripper being effective to wedge in one axial direction with the cable and to slide in the other direction, and the other set of each gripper being oppositely effective. Each gripper also has a disabling body displaceable between end positions and through a central position with the body disabling one of the respective sets of jaws in one end position, the other set of jaws in the other end position, and neither set of jaws in the central position. A hydraulic controller is connected to the actuators and to the disabling means for reversing the actuators and the disabling means in accordance with the position of the actuators.

    The invention relates to hydraulically driven devices for moving ruzas and, predia, for transporting goods by rope.
    A hydraulic device is known, comprising a subcirculation unit with a hollow piston rod, two clamping heads, each of which includes a housing having a jQ distribution chamber and connecting the working fluid to it, a clamping sleeve installed in the distribution chamber, wedge-shaped bodies and spring-loaded clamping elements installed- 15 with the ability to interact with the latter, with the first of the clamping heads mounted on one of the ends of the hollow piston rod, and its opposite end is connected 20 to the device direct control of the direction of movement of the clamping heads (German patent No. 1219199, cl. 35 d 2/05, 1966).
    The disadvantage of this hydraulic device is that the movement 25 is carried out in step intervals, which makes it difficult to stop the device in the required place and change the direction of the shift.
    The purpose of the invention is to increase the effect of the device by bleeding the continuity of its two marriages.
    This goal is achieved by that the device is equipped with an additional hydraulic stem with a piston 35 piston rod, at one end of which a second clamping head is installed, a central pipe with a gimbal suspension and connecting elements, and the hydraulic cylinders are installed at 40 ends of the central pipe by means of connecting elements; hydraulic with two electric 45 alarm sensors connected to the high piston rods, the clamping elements are made in the e pad, and between them a spring which is connected Kaladi 0 chuck head, and the clamping sleeve. made with the possibility of alternate interaction with the clamping pads.
    FIG. 1 shows the device 55 with cable traction, air above; in fig. 2 - the same section.
    The hydraulic device is predominantly with a cable;
    of two hydrodilindars 1 with hollow piston rods 2 installed with connecting elements 3 on the ends of the central tube 4 having a cardan suspension 5. At the ends of the hollow piston rods 2 clamping heads 6 are installed, each of which has a housing with a separating chamber 7 and connections 8 to feed the last working fluid. In the & wedge housings 9 with clamping elements made in the form of pads 10 preloaded with springs 11 are installed in each clamping head, and clamping sleeve 12 is installed in a distribution chamber 7 with alternating interaction with pads 10 clamping sleeve 12, in neutral position the pads 10 are clamped under spring action 1I. In addition, the device contains an electrohydraulic device 13 controlling the direction of movement of the clamping heads with two electrical signal sensors 14 connected to the hollow piston rods 2, and the clamping heads are connected to guides 15 mounted on the hydraulic cylinders and taking torque on heads in the process of the device. A hydraulic device is placed on a tension rope 16, passed through clamping heads, hollow piston rods and a central tube. The device works as follows.
    Through one connection 8, a working fluid is supplied to one of the cavities of the working chamber 7 of one of the clamping heads, with the result that the clamping sleeve moves and moves the clamping pads 10, unclenching them. Then, the working fluid is supplied to the hydraulic cylinders 1, from which zero rods are advanced, moving the load attached to the gimbal suspension 5. When the brushes 2 reach their extreme position, the working fluid is fed into one of the cavities of the distribution chambers 7 of the second clamping head at the same time stopping the supply to the first and other cavities of the hydraulic cylinders, as a result of which, in the first clamping head, the clamping sleeve returns under the action of the spring 11 to the neutral position, the clamp
    rope pads 10 and podgivaniya device together with the load rods hydraulic cylinders to this clamping head. When the rods reach their second extreme position, the cycle repeats, thereby almost continuously moving the hydraulic device along the rope 16. For reversing the movement, the working fluid is fed into the other cavities of the working chambers of the clamping heads.
