Product name Industrial flexible lifting door

Product introduction

(1) Design conditions

1, wind resistance grade: standard wind pressure 55kg/m2; The safety factor is 1.4, that is, the z design wind pressure is 77kg/m2.

2, rising speed: 4-6 m/min

3, the curtain has anti-aging and wear resistance

4, the overall sealing performance of the door is good

5, double curtain insulation (single thickness of about 0.8mm)

(2) Design scheme

1, the main principle of traction curtain rise

The company's traditional technology for this type of door is adopted: the split curtain is stacked horizontally and horizontally

2, the composition of the door curtain

The door curtain consists of double-sided industrial belt (high polymer fiber biaxial warp knitted fabric and PVC coated composite) and rib; Ribs can be composed of steel truss structural beams with fixings. This combination can not only ensure the wind strength requirements of the door curtain under high wind conditions, but also reduce the weight of the door curtain, so that the operation is convenient. The principle of wind resistance is that the wind is transferred from the door curtain to the rib, and then from the rib to the building steel structure and the ground

3. Power system

The power system consists of a group of motors, reducers and braking systems.

4. Control system

The control system consists of the motor control system and the motor overload protection system, and all the components are assembled in a control box.

Motor (SEJ) : Control box (SEJ) : 380V

5. Security system

During the opening process or power failure, the braking system in the power system provides enough braking force to prevent the self-sliding of the door curtain under any circumstances, and the strength of the sling safety system is 7 times. In the case of the suspension belt breaking, equipped with automatic hook anti-fall system, can effectively prevent the door body from falling.

6. Sealing system

In order to effectively ensure the integrity of the sealing system, the steel plate is sealed between the door curtain and the sliding door post surface.

(3) The main advantages of this product

1, the system is safe and reliable, the strap is broken, the use of our patent anti-fall protection system without making the door body fall.

2, the use of dual wind resistance system, that is, the upper and lower stretching system and rib uniform wind resistance system.

3, the use of multi-point lifting system, such as a sling broken, the door body can still run, if the bottom beam is broken, the door body still does not fall

4, maintenance guarantee: our company in the local has a stable and reliable technical team and a certain number of spare parts storage; Therefore, in any case, if the door fails, our company has the ability to troubleshoot in time.
