Electrohydraulic actuators are standalone, self-contained systems that perform powerful tasks without external piping. They typically include an electric servomotor driving a hydraulic pump — often an axial-piston unit. Other components include a hydraulic cylinder, tank, valving and charging circuits. Because they are fitted with their own closed fluid circuit, they require only a small amount […]
Proportional valves make crane precision possible
Cranes lift heavy loads, and precise control of the lifting process is paramount for safety and efficiency.
