1. The closure machinery consists of motor, closure device, frame, and protective cover, etc.; it employs a three-stage reduction method, using helical gear drive for a higher output torque. The accompanying steel frame helps to overcome uneven civil engineering, reducing the overall noise and vibration of the machinery.

2. Utilizes outdoor-duty long-time operation motors with a protection rating of ≥IP55. The stroke control mechanism operates on the decimal counter principle, ensuring a stroke accuracy of 0.5%. Torque protection control is achieved by the worm generating an axial displacement to trigger a microswitch, thereby protecting the electrical appliance.

3. Easy operation and maintenance, with both on-site and remote control capabilities.
