This video explains about the working of a hydraulic ram or hydraulic cylinder.
The hydraulic ram is used in a hydraulic circuit for accomplishing a particular work. It actually converts the hydraulic pressure energy to mechanical energy "productive work". This video clearly explained how a hydraulic ram works and how the resultant components linked with it moves for carrying out a work. It also covers the function and working of the control valve or valve block and its spool movement resulting in the corresponding movement of the ram.
