The hydraulic system consists of a package hydraulic cylinder, an electrical control system, and a mounting bracket. The complete system can share an electrical control device. Each Dam Gates Hoist Hydraulic Cylinder has a displacement sensor. This helps achieve high accuracy in arc gate opening angle and synchronization of the cylinders. The hydroelectric cylinder is designed to operate on low-voltage systems with high-voltage supplies.

The hydraulic power unit comprises a throttle valve, directional valve, and relief valve. The hydraulic cylinders in the Dam Gates Hoist are standard components, which make maintenance simple and cost-effective. Each cylinder is equipped with a displacement sensor, which helps achieve precise arc gate opening angle and synchronizes the operation of the entire system. The electrical control unit typically consists of two sets of cylinders and a PLC to monitor and control the system.
