Hard fast rolling door - Renqiu Wojing International Trade Co., Ltd.

·Hard fast door width 1250mm-5000mm, height 2000mm-7500mm; opening speed 1.2m/s-2.5m/s, adjustable; up to 5.88m/s; closing speed not less than 0.6m/s, adjustable.

·Hard fast door adopts double helix worm gear guide rail, making the door body run more quietly and smoothly. The

bearing capacity is greatly increased, friction is reduced, and the operation is faster. There is no contact, friction, or wear between the door panel and the connector when rolling up. The opening and closing are smooth and fast, which increases the service life of the door body.

·The wind resistance performance is 3.5kpa, reaching the international level 6, that is, the wind resistance level 12 (120km/h).

·The thickness of the aluminum alloy insulation door panel is not less than 43mm, the surface is anodized and organically colored, and the interior is filled with polyurethane (CFC-free) industrial insulation material. The door panels are sealed by soft connection strips, and the folding life of the soft connection part is more than one million times.

·The hinge load-bearing design makes the door curtain joint free of stress, the door panels do not contact each other, and the flatness can be maintained after long-term use; the door panels are sealed with EPDM cold-resistant sealing strips, which can effectively isolate the temperature and reduce energy loss, and have good sealing, heat preservation and sound insulation.

·The load-bearing bearing adopts automatic core adjustment and double needle bearings. The pressure resistance of this bearing is 3 times that of ordinary bearings, and it does not affect the normal operation of the door body when the building structure is deformed in daily use. The bearing has a self-adjusting function and can quickly respond to eccentric transmission without abnormal noise.

·The motor drive system adopts the industrial door service motor system and rare earth permanent magnet synchronous motor; it is equipped with an emergency manual opening device.

·When the power is off, the electric control system can open the motor brake at any time, and the door body can be lifted with the help of the balance system, which can effectively solve the problem that the door body cannot be opened due to power outage or failure.
