It is an electrically operated hyraulic power unit, especially used for pushing down the blocks that are seperated from the massive rocks by cutting with diamond wirw or by using integral drill steels at marble or granite quarries. The unit has two different sized hydraulic cylinderic jacks and four hydralic high pres­sure hoses each 10metres long is so lasting and also it is easy to carry and use it. It is possible to work with two hyraulic jacks together or seperately. Each jack has 120 tons pushing capacity and their pistonsa re made of specially treated steel. With a special designed valve system the jack and used hydralic are protected. The hydraulic pump, that takes its energy from an electric motor has radial piston and designed for working under heavy conditions. The complete system is protected with safety valve that is put into the hydraulic. The working pressure can’t go up more than 700 bar by the hindering of safety valve.
