Application

FACTORY
 

The door openings of factory buildings are large and require greater wind resistance. The door panels of industrial lifting doors are made of hard material and have strong wind resistance.

 

 

 

LOGISTICS
 

Logistics parks have frequent daily transportation and are located outdoors, requiring high security. Industrial lift doors are designed with strong panels that are both pry-resistant and theft-resistant.

 

 

 

WAREHOUSE
 

The warehouse environment requires ventilation, dryness, brightness, cleanliness and unobstructedness, and it is more efficient to use it with industrial lifting doors.

 

 

FIRESTATION
 

When the fire rescue center responds to an emergency, it needs to be opened quickly to facilitate the dispatch of fire trucks. The one-button linkage system of the industrial lifting door can respond quickly.

Product features

• Industrial sectional doors can provide a variety of lifting methods according to the actual civil structure on site: such as straight type, standard lifting type, high lintel lifting type, low lintel lifting type, etc, so that your building space can be customized.
• The industrial sectional doors have an unique roller shafe design, which distrobutes the force of each hinge to the wheels on both sides, so that the door can run gently and extend the overall service life.
• The door panel is made of sturdy material with double sided hot-dip galvanized steel, embossed on the surface and embossed stripe design, and the inner layer is a high-density polyurethane form insulation layer. The door panel has the function of preventing fingers from being pinched.
• The joints of the door panels are equipped with sealing rubber to ensure a good sealing effect. The front and back panels of the door panels are made of coated steel plates, which have high corrosion resistance and weather resistance.
• Panel: A. Two layer of 0.4mm powder coated galvanized steel plate, PU foaming density 48±2kg/m3;B. Surface printing layer: 30um; C. Total thickness: 40mm (standard) 50mm/75mm/100mm (optional)
• Safety device: 1. Spring brake device (anti-broken); 2. Service life: 100000 opening and closing; 3. Driving force: 140N;
• Accidient dropping safety device: Door bottom equips with the avoid dropping steel cord, to secure the accidient dropping within 50mm
• Guide rail: A. Special design three angle wheel brace secure smooth rolling of wheel; B. Mute nylon wheel, noise level: ≤60db
• Beam seals: Epdm sealing rubber is installed onto top, bottom and sides
• Buffer and hinges: 2.5mm steel plate
• Bottom wireless safety airbag: It makes the door doby lift back when touching somthing during closing and stops the movement during opening

Product parameters

• Lifting speed: 0.2m/s
• Door panel: Double layer hot-dip galvanized embossed anti-corrosive sprayed steel plate, door body polyurethane density is 48, door panel thickness is 40mm, door panel height is 510mm
•  Track and hardware: Support the door body and guide the door boty to run, adopot high-quality anti-corrision metal guide rail, auxiliary rail and guide rail bracket, thickness 2mm. The uniqye design of the hardware is supplemented by other accessories to ensure that the door runs smoothly with low noise, excellent balance and high-strength safety performance
• Wind resistance: ≥450N/m2
• Balance system: Use the power of the torsion spring to balance the weight of the door
• Torsion spring system: Including door shaft, torsion spring sleeve, torsion spring (lifespan is 50,000 times at least), sheave, coupling etc. The material is high quality torsion spring, with a lifespan of more than 30,000 times, and special processing technology
• Torsion spring anti-breaking system: After the door has been used for a certain number of years, the guide spring is easily broken when fatigued. The torsion spring anti-breaking system will lock the transmission shaft once the torsion spring breaks, thereby effectively avoiding greater safety accidents
• Wire rope anti-breaking device: The steel wire rope anti-falling device is installed at the bottom of the door panel, no matter when the door body moves up or down, the wire rope suddenly brakes, self-locking ensures that the door body will not suddenly slide down and prevent accidents
• Safety pressure switch: When the door body is pressed against an object during the descending process, the door body will instantly rebound and rise automatically
• Sealing: There is a sealing strip at the bottom, and the materail is made of EPDM material, which has the characteristics of anti-low temperature and anti-fracture, inliad installation, and good sealing effect, The surroundings are sealed to ensure the performance of rainproof, dust-proof, sound instaltion and heat insulation.

Anti-fall Device

Anti-fall device is a key component to ensure the safe operation of industrial doors. It is mainly used to prevent the door body from falling suddenly due to faults (such as wire rope breakage, drive system failure) during operation, avoiding casualties, equipment damage and property losses.

Spring Bumper

When the motor fails, the booster holds the door to prevent it from running off the track.

When closing the door, push the door panel from the curved track to the vertical track.

 

 

 

Safety Production Device

By sensing obstacles and rapidly inflating, a buffer barrier is formed to prevent crushing injuries to personnel, equipment or cargo when the door is closed.

Spring Broken Device
When the torsion spring breaks, it blocks the torsion spring to prevent the door panel from falling and injuring people.
