PowerArm Engineering specializes in high-performance hydraulic cylinders. A hydraulic cylinder is a device that is designed to give a one way directional thrust across in a single or unidirectional stroke. These cylinders significantly play a major role in construction of hydraulic equipment, like elevators and a variety of civil engineering machinery, vehicles like cranes, earth moving equipment and allied applications.These Hydraulic cylinders typically generate their power from the highly pressurized hydraulic fluid.The hydraulic cylinder mainly consists of a cylinder or a barrel, a piston, a piston rod. The piston moves back and forth through the help of the rod, within the barrel.
