The invention relates to mechanical engineering and can be used to rescue and dismantling operations for extending narrow openings, as well as for lifting, holding, moving and tightening of cargoes. Hydraulic unclamping comprises a hydraulic cylinder with a piston rod-piston, two levers, the pressure sleeve and the downcomer, the control unit comprising a hydraulic valve and check valves, the control element configured as a handle associated with the control unit, a handle mounted on the housing of the hydraulic cylinder. Levers are pivotally connected with the plug mounted on the end of the rod, and the housing of the hydraulic cylinder rods 9. At the ends of the arms are mounted by pins replaceable tips, which are provided with holes. On the outer surface of the replaceable tips are made limiter and fixing oblique teeth, the apex angle of which is directed towards the limiter. At the ends of the pressure and drain hoses gidrorazemy installed quick connection. 1 ZP f-ly 1 Fig.
