1. 5. The frame at the bottom of the gate shall be designed for 2 sets of process lifting points to be used when the lifting mechanism fails.
2. Indicator of wind resistance performance of flexible lifting gate:
2. The overall wind resistance of the gate is 66.42-72.3810n /m2.
2. 2. The dynamic anti-wind series is 11 wind and the wind speed is 28.5-32.6m/s.
3. Control system: control system: schneider brand can increase the service life of transmission system.
3. 1. When the gate is not raised and lowered, the motor is always locked;
3. 2. The limiter of the flexible lifting gate can control the lifting device to stop working when the gate rises to the rated height and the lifting device can stop working when it reaches the bottom line.
3. 3 flexible lift door inside and outside of the workshop are equipped with action button box, its running up and down for some dynamic contact operation, the operator can control in both inside and outside the gate of the elevator, and equipped with sound and light warning light lifting;
3. 4 waterproof 500 x 600 x 280 control cabinet, with waterproof upper and lower down switch.
4. Main technical data of the door body:
4.1 flexible lifting gate structure is composed of horizontal frame, bottom frame and upper frame, and PVC base cloth is used on the bottom of the bottom frame.
Sealed, the top beam is sealed with color steel plate, and the side of the column is sealed with color steel plate to achieve good sealing performance and no dust overflow.
4.2 the inside and outside of the flexible lifting gate is made of special PVC base cloth. The horizontal frame of the gate and the bottom frame of all gates.
And the upper frame adopts truss structure, and the main structural parts of the frame are made of pitch steel pipe.
4.3 technical data requirements for special PVC base materials:

5. Safety measures:
5.1 technical guarantee:
The design basis of the flexible lifting gate shall be based on the national standards concerning hoisting machinery, steel structure and electrical appliances. The strength, winding, internal force and stability of steel structure are calculated and checked to ensure the reliability of product design. The selected raw materials, purchased parts, matching kits, mechanical parts and electrical components all select domestic famous manufacturers and famous brand products.
5.2 sensing, detection and sound and light alarm system:
flexible lifting doors should be equipped with sound and light alarm, sound and light signals when lifting operation,
No operator or object is allowed to pass through the gate during the lifting of the gate;
lower limiter: at the bottom of the rail profile with plunger contact sensor stop, when the door down close to the bottom, stop the plunger, access to the most lower level framework order contact, door completely shut down at the same time, the lifting mechanism to immediately stop running;
upper limiter: at the bottom of the beam is equipped with plunger contact sensor stop, when the gate hoisting near the top, the upper level framework exposure to stop the plunger, the lifting mechanism to immediately stop running;
6. Anti-falling safety system:
6.1 clamp type falling preventer (German OUMA technology patent) is a safety device used to prevent heavy objects from falling in the process of lifting and falling. If the weight is caused by a mechanical failure in the lifting process, it will cause sudden fall. If it is not stopped in time, the great inertia force will cause great damage and personal injury accidents. The preventer can prevent the occurrence of such an accident by locking the gate in a safe position immediately after the weight falls.
6.2 the anti-falling device can effectively prevent the falling of the door plate and the device of the anti-falling device into the anti-falling shield to ensure the timely stop of the door body.
Rated load 6t
The falling lock distance is no more than 50mm.
Allowable impact load 12t.
The diameter of the brake rod is more than 25.
7. Coil door steel construction system and paint technology:
7. 1 choose baosteel production quality steel, through fine welding, high quality paint processing.
8. Sealing device:
8. 1. The guide rail and rubber capsule of the special aluminum alloy in the lower part of the door are sealed, and the two sides of the door guide are sealed with the base cloth.
It can prevent insects and sand from entering the room.
