The hydraulic power pack is custom built module for operation and control of any standard or special purpose hydraulic equipment. It consists of pump-motor unit to produce flow of hydraulic fluid to, control block to house various control elements and filtration components. All these components are laid out on top of a reservoir on a super fabricated structure. It is used at isolated places or small independent systems. The project starts with the observation of the need of an offline hydraulic power pack: To test the hydraulic cylinders for their total performance before installation in their working circuit. Checking the stand balancing mechanism of spare mill stands. Moving the cylinder during erection when the regular hydraulic system is under shutdown….
