Product description

The screw hoist, also known as the screw hoist, is a machine that uses a threaded rod to connect directly or through a guide slider, a connecting rod and a gate leaf, and the screw moves up and down to open and close the gate. With the extensive development of water conservancy and hydropower projects, hoists and gates used in engineering projects such as river dykes and hydropower stations in reservoir irrigation areas have been widely adopted

Advantage:
Because the winch type hoist has many speed reduction programs and large speed ratio.
It has been enlarged by the pulley block and is suitable for gates with larger orifice sizes and heads.
The wire rope can be wound in a single layer or multi-layered to facilitate opening of a gate or deep hole gate with a large stroke.
The direction of the force of the wire rope can be appropriately oscillated, or the direction of the force can be changed by the additional embedded diverting pulley. Therefore, the cooperation of the gate and the hoist has greater flexibility.
When electric is used, the speed of opening and closing is fast, and it is suitable for accident gates and gates that are frequently opened and closed.
