Jdoor China

Terminal buffer
Based on the characteristic of constant torque motor system, so that the door body running more smoothly, and solves the noise problems in the operation of the door body, and the end of buffer technology is more effective protection of the reducer and brake, can adjust different speed according to the actual needs of digital, fast slow stop length change, reduce the components scratch, especially the protection of the reduction mechanism is most prominent.

Door curtain mechanism
JDOOR hard and fast curtain structure: door curtain is divided into three parts: split assembly structure, broken bridge heat insulation aluminum alloy door plank, multi-layer sealant strip, silencer bearing hinge, polyurethane guide wheel and so on:
1, the total thickness of aluminum alloy curtain is 40mm, which is filled with polyurethane energy-saving materials. The surface is treated by anodizing and organic coloring. The tensile strength is over 230B/MPA, which is GB/T5237, and the color is
. 2, after connecting the aluminum door curtain with the soft bonding strip, the folding life of the soft connection part is over 1200000 times;
3, the angle chain load-bearing way design makes the door curtain joint without force, the door curtain does not change, and can keep the evenness after a long time;
When the door body runs through a polyurethane material belt, the curtain slides in the orbit, and no friction and dryness will occur at the highest speed.

Safety system
Otto Nicks: infrared safety protection door frame are arranged on both sides of the screen photoelectric photoelectric or optional safety induction to the fast door below the moving object, the door will be kept open; when the door body falls below the object through the door of opening to the maximum open position, to be under no obstacle to delay fall.
Optional or increase the airbag device, when the door body falls the fast door touches an object, the airbag receives a certain pressure to the back door of immediately open the open position.
