Hydraulical rotary actuators are used in areas where you have to generate rotations through hydraulic pressure. On the inside of the power unit a hydraulically driven linear movement will be converted to a rotational movement. Hydraulical rotary actuators are providing a high torque during the whole working process and there is no additional lifting mechanism needed. The movement and the torque are constant during the working activity. Due to the high force density of the hydraulic system, you can implement the it in your construction without any further space issues.
