The winch is used in various large-scale water supply and drainage, water conservancy and hydropower projects. Used to control the lifting of various large and medium-sized cast iron doors and steel doors to achieve the purpose of opening and closing.

Hydraulic hoist, hoist, door hoist, hand wheel hoist, lantern hoist, chain hoist, spiral hoist, double hoist, etc.

   Structural features

1. Rolling door machine includes motor, rolling door machine, frame, protective cover, etc.; adopts three-stage speed reduction method, adopts screw drive, and has higher output torque. The steel frame of the gate hoist overcomes the unevenness of the civil construction and reduces the noise and vibration of the whole machine.

2. Use outdoor long-life working motor, protection grade ≥IP55. The stroke control mechanism adopts the principle of decimal counter to control the stroke error of 0.5%. Torque protection control is the principle of activating micro switches to protect electrical appliances through the axial displacement of the worm.

3. Convenient operation and maintenance, and can be operated on site and remotely.
