Describe the principle of operation of a double acting hydraulic ram. - Leaving Cert Engineering - Question 1 - 2017

A double-acting hydraulic ram operates by utilizing hydraulic fluid on both ends of its piston. This allows for movement in both directions, as hydraulic fluid is supplied to facilitate both extension and retraction.

When hydraulic fluid is pumped into one end of the ram, it pushes the piston outward, creating a force that can perform work. Conversely, when the fluid is directed to the opposite end, it retracts the piston back into the cylinder. This system is effective for applications that require high force in both directions of travel.

Overall, the design of a double-acting hydraulic ram allows for efficient operation and strong performance in various hydraulic applications.
