Lifting gate principle
|
The lifting door is precisely balanced, the weight of the door panel is completely balanced by the spring, and the door can be easily fully opened in the manual state, and the force used should not exceed 150N. The principle of realization is to adjust the diameter of the door wire wheel + configure different types of torsion springs according to the size and installation mode of the door during production. When the door is in operation, no matter which height is stopped, the torque x diameter = torque is constant, so the motor only plays a driving role in the operation of the door, effectively extending the service life of the motor, and the power of the motor is very small. It has the effect of environmental protection and energy saving, and the
practical life of the spring can reach more than 30,000 cycles. |

Door plate
|
The top and bottom are made of high-quality galvanized steel plate, and the door plate filled with rigid foam polyurethane is
environmentally friendly. Thickness 40MM; Door panel production for the assembly line, continuous production, filling density, strong, heat insulation, appearance color effect is good, high strength. |

|
Tightness
|
The air tightness of the installed door is approximately 2.5m3/m2/h (50 pa pressure
|
|
Balancing system
|
The lifting doors are balanced by a high-strength spring system with a minimum service life of 30,000 cycles. All spring surfaces
are heat treated for better corrosion resistance. |

Torsional spring
|
Accurate configuration calculation: high-strength external torsion spring balancing system, using accurate professional calculation formula according to the size, weight and sliding mode of the door to accurately configure the torsion spring, to ensure that the door body up and down easily. torsion spring is made of 82b and is treated by advanced thermal technology. Each
spring is equipped with a spring break-proof device, and in the event of any spring break, the door will stop within a range of 20cm |
