Control Method of Industrial Lifting Door (Sliding Door)
The standard control method is to use three control buttons on the control box to control the opening, stopping, and closing of the door. According to customer needs, multiple control methods can be implemented on the basis of electric doors.
1. Button style control
Control button switches can be added on the outside of the door to control its movement on both sides.
2. Pull rope switch control
Install a rope switch on the wall so that operators can operate the door without leaving the vehicle.
3. Remote control
Flexible wireless controls such as "one-to-one", "many to one", and "one to many" can be achieved through a remote control.
4. Geomagnetic control
Because the geomagnetic ring only works on metal objects (such as vehicles, trays, etc.), this can avoid mixing of people and greatly extend the service life of the gate.
5. Optoelectronic control
Install a photoelectric switch on the outside of the door. When the light beam is blocked, the door can be opened and automatically closed through other devices such as automatic delay function. This device can also be used as a safety function.
6. Radar control
The device automatically sends a door opening signal when it detects moving objects (such as vehicles, personnel, etc.) under the door, achieving the opening of the door. Close the door through other automatic devices.
7. Remote control
Communication devices such as mobile phones can be used to control the door.

| Both the upper and lower parts are made of high-quality galvanized steel plates, and the interior is filled with rigid foam polyurethane door panels, which are environmentally friendly door panels; Thickness 40mm; The production of door panels is done on an assembly line and continuously, with high filling density, durability, insulation, good appearance color effect, and high strength. Wind pressure resistance parameters: standard wind pressure 450N/㎡ (wind resistant ribs can be added) The surface coating thickness of the color steel plate is 25-30 microns, and the door panel surface is sprayed with seven layers of paint, effectively ensuring the beauty and corrosion resistance of the product. Please refer to the product technical manual for details. The standard color for the inside and outside is white gray. The foam density of the door panel is 48Kg/m3 ± 2 Kg/m3, and the foam material is fluorine free polyurethane, a Japanese imported brand. The U-value test indicator is 0.84W/m2 º C. The U value between the door panels is 0.4 W/m2 º C, and the door panels do not support combustion, with a wind resistance of 450N/m2, equivalent to a level 10 typhoon. To assemble folding and other accessories, galvanized steel strip with a thickness of not less than 2mm must be added to the door panel. The door has good thermal insulation performance. The connection of the door panel is equipped with a sealing gasket to block the heat transfer and reduce heat loss. Airtightness: The air tightness of the installed door is approximately 2.5m3/m2/h (under a pressure of 50 Pa). Wind resistance: 480N/m2; Equivalent to being able to withstand winds of level 10. Door panel edge sealing profile: The surface of the edge sealing profile of the door panel is completely sprayed with paint Balance system: The lifting doors are balanced by a high-strength spring system, and the minimum service life of the spring is 30000 cycles. All spring surfaces have undergone heat treatment for better corrosion resistance.

Principle of lifting doors |
| The lifting door adopts precise balance, and the weight of the door panel is completely balanced by the spring. In manual mode, the door can be easily opened completely, and the force used should not exceed 150N. The principle of implementation is to adjust the diameter of the door wire wheel and configure different types of torsion springs according to the size and installation method of the door during production. When the door is running at any height, the torque x diameter=torque, which remains constant. Therefore, the motor only plays a driving role in the operation of the door, effectively extending the service life of the motor. The power of the motor is very small, which has the effect of environmental protection and energy saving. The practical life of the spring can reach more than 30000 cycles. |
