Double-pointed screw actuator is mainly used in canals, reservoirs, wastewater treatment plants, power plants, and other locations.

Gates with a wide span feature two hoisting points. To ensure smooth opening and closing of the gate, synchronization of the two hoisting points is required, necessitating the selection of a double-point hoisting mechanism. Generally, the width is defined as exceeding 2.5 meters.

Alternatively, you can opt for a single-point lifting and closing machine. The dual-lifting closure machine is operated simultaneously by two lifting machines, including one main unit and one auxiliary unit. It maintains good balance and stability.
