Hoists are used in various large-scale water supply and drainage projects, hydraulic and hydroelectric engineering. They are employed to control the lifting and lowering of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing.

I. Features:

1. The hoist consists of a motor, hoist mechanism, frame, protective cover, etc.; it adopts a three-stage reduction method with screw transmission, providing greater output torque. The hoist is equipped with a steel frame to overcome uneven civil construction, reducing overall noise and vibration.

2. It uses an outdoor-type long-duty cycle motor with a protection等级 ≥ IP55. The travel control mechanism employs the principle of a decimal counter, with a travel control error of 0.5%. Torque protection control is achieved through axial displacement of the worm, which triggers a microswitch to protect electrical components.

3. It is easy to operate and maintain, enabling both on-site and remote control operations.
