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

Gates with a large span have two hoisting points. To ensure smooth opening and closing of the gate, it is required to synchronize the two hoisting points, necessitating the use of a double-point hoisting machine. Generally, the width is defined as exceeding 2.5 meters.

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