FIELD: construction.SUBSTANCE: installation comprises a frame, a carriage with a control unit arranged on it with a technological adapter, a hydraulic cylinder connected by the body to the frame, and with the stem to the carriage, at the same time the frame has guides for carriage rollers. The frame is made of the carriage frame and the hydraulic cylinder frame connected to each other.EFFECT: increased reliability of operation and reduction of time for installation assembly and disassembly, increased volume of working space in a well and increased efficiency of performed works due to placement of a hydraulic cylinder with stem length that is larger than in a prototype outside the limits of the well, and whenever it is required to increase force characteristics.3 cl, 2 dwg |
