Flexible Door Features:
1. Large coverage area (800~1500 m2), strong wind resistance (up to 12 typhoons), good thermal insulation, high sealing, stable and reliable, easy to operate, and easy to maintain
2. The lifting mechanism of the flexible sliding door is equipped with two hydraulic pushrod brakes and one height limiter, as well as upper and lower limit switches, ensuring the safe operation of the flexible door.
3. The lifting mechanism is driven by an induction-brake AC motor, which is connected to a cylindrical gear reducer to drive open gears. This setup powers the drum with parallel shafts, used for winding and unwinding the lifting steel wire rope.
4. Hydraulic pushrod brakes are installed on the shaft joint between the motor and the gear reducer, as well as on the other output shaft of the gear reducer's high-speed shaft. Any of the brakes can perform the braking function, ensuring the safe and reliable lifting and lowering of the gate.
5. Utilizing eddy current braking to regulate the speed of the gate's rise and fall. A height limiter is installed on the drum shaft of the wire rope, limiting its upper and lower extreme positions. The lifting mechanism is equipped with multiple sets of pulley blocks.
6. The interior and exterior sides of the flexible lifting gate are sealed with fabric (such as waterproof canvas or PVC fabric). The horizontal and bottom frames are constructed with truss structures, made of rectangular steel pipes. Aluminum alloy materials can also be used for assembly.
7. The horizontal and bottom frames of the flexible sliding door are equipped with roller bearings at both ends, utilizing three-sided rolling bearings for smooth up and down movement within the side tracks of the flexible door, reducing frictional resistance.
8. The flexible lifting gate is equipped with a safety brake that automatically engages during stopping or in the event of a wire rope breakage, significantly enhancing the safety factor.
The wind pressure resistance of the flexible lifting door is 50-60 kg/m².
9. Overall dimensions range from 5-40 meters in height and 8-140 meters in width, with a total weight of up to 0.5-20 tons. They are composed of 3-20 blocks, each measuring 1-2 meters in height, 5-60 meters in width, and 0.2-1.4 meters in thickness (with the thickness of the streamlined polyester conveyor belts with PVC coating or glass fiber curtains being 1mm). Each door is controlled by an electric control system. The opening speed is fast.
Minutes to reach 9-18 meters. Strong wind resistance, can withstand typhoons up to 12 levels, wind pressure resistance of 500n/㎡. High resistance.
