EQUIPMENT FOR PRE-TENSIONING WIRE ROPE REINFORCEMENT AND REINFORCEMENT RODS TENSIONING JACKS FOR MONO STRAND (WIRE ROPE REINFORCMENT), NOMINAL PRESSURE 70 MPa, HYDRAULIC STROKE RETURN «EVOLUTION» SERIES Tensioning jack is designed as a jack with hollow rod, hydraulic return with front position of 3-segment wedge for strand capture when tensioning, so strand detwisting is impossible at the loading moment (there is no necessity in the special device to prevent jack’s body turning, and there is no need to use strand longer then the tensioning jack). The jack is equipped by safety valve. Tensioning jack is equipped by 2 hoses 500 mm length each, half quick coupler in order to connect with pumping unit by high pressure hose of required length. Tensioning operation is made in accordance with instruction using remote control panel of special pumping unit НЭЭ-1,0(2,0)И5(10) Ф(Т)1-И-DNE. Model
