Screw hoist is one of the leading products of Yubang Water Conservancy Equipment. According to the number of lifting points, the hoist is divided into two models: single lifting point and double lifting point. According to the driving mode, it is divided into three forms: manual, electric, and flashlight. The tonnage includes 3 tons, 5 tons, 8 tons, 10 tons, 12 tons, 15 tons, 20 tons, 25 tons, 30 tons, 40 tons, 50 tons, and 60 tons. It is mainly used for opening and closing gates in water conservancy projects and is a supporting machinery for water inlet and outlet gates in agricultural water construction, hydropower stations, etc. It can be used in mountainous areas, plains, areas with or without electricity.

The screw opening and closing machine is divided into manual and electric dual-use, and can be equipped with an electric device and 2 hand cranked handles according to user needs for manual use.

The screw opening and closing machine adopts worm gear, worm gear variable speed, and nut rotation to make the screw move up and down, driving the gate to open and close.

The length of the screw can be produced according to the user's engineering requirements, with double lifting points and lifting point spacing designed according to the user's requirements.

Screw hoist is a mechanical device used to control the lifting and closing of various large and medium-sized cast iron gates and steel gates. Commonly used for various large-scale water supply and drainage, water conservancy and hydropower projects. Classified by type, it can be divided into hoist hoist, gantry crane, handwheel hoist, hand-operated hoist, screw hoist, etc.

The significance of screw hoist in hydraulic structures is significant, and the normal operation of the hoist is a crucial issue. Once the hoist malfunctions and cannot be opened when the gate should be opened, it can lead to a major disaster. The quality of the opening and closing machine itself is assessed layer by layer, and generally there will be no problems. The important thing is regular maintenance. If problems are found, they need to be reported in a timely manner.

1. The screw type hoist is currently being installed. Be sure to keep the base stable. If not, proceed with operational matters. It is easy for the screw to tilt. Or damage to the components due to local stress, which can be very troublesome,

2. During the installation of the screw type hoist, we need to place the manual screw type hoist on the installation position. After the screw comes from above the machine, we remove the limit plate. This way, the device can be well connected,

3. During the installation of the screw type hoist, the infrastructure for installing the hoist must be stable and safe.

4. The screw type hoist is currently being installed. Another point to note is that it must be installed according to the drawings and instructions. Its installation is better than cast iron gates.
