Screw type hoist

Screw hoist is a common type of hoisting equipment.

It mainly consists of screws, opening and closing machine nuts, transmission mechanism, frame, and other parts. Its working principle is to drive the transmission mechanism through manpower or electricity to rotate the screw, so as to raise or lower the gate connected to the screw and achieve the opening and closing action of the gate.

The screw hoist has the advantages of simple structure, convenient installation, and low cost. It is suitable for small water conservancy projects, such as channels, small water gates, etc., and is used to control the flow of water.

Its operation is relatively stable and can accurately control the position of the gate. However, relatively speaking, its opening and closing force is limited, and it is not suitable for large gates or situations that require a large opening and closing force.

During use, it is necessary to regularly maintain and upkeep the screw hoist to ensure its normal operation and good working condition, in order to ensure the safety and effective operation of water conservancy facilities.
