Double-pinion screw actuators are mainly used in canals, reservoirs, wastewater treatment plants, power plants, and other locations.

Gates with a large span have two hoist points. To ensure smooth opening and closing of the gate, it is required to synchronize the two hoist points, necessitating the selection of a double hoist opening and closing mechanism. Broad widths, generally defined, exceed 2.5 meters.

Alternatively, you can opt for a single-point hoist. The double-point hoist is operated simultaneously by two hoists, one being the main hoist and the other the auxiliary hoist. It maintains good balance and stability.
