In modern industrial production, productivity is the key. And with the development of science and technology. Industrial sectional door is a kind of intelligent and efficient doors, is gradually becoming an indispensable part of industrial production. Sectional doors have a variety of lifting methods to adapt to a variety of environments. In this article, we will discuss the characteristics of sectional door and its several lifting methods.
Features
Industrial sectional door, also known as sectional overhead door. It is applicable to the inside and outside of the building. The sectional doors have good wind resistance and anti-theft. Through the torsion spring tension balance, pulley slide rail sliding, frequency intelligent control system electric control operation system. Torsion spring using 82B, 60Si2Mn material life up to 30,000 times andThe surface can be done Dacromet spray treatment surface galvanized color to play the effect of corrosion and rust. 40mm thick high-density polyurethane foam door both heat preservation and impact resistance, lifting the door appearance is usually white and grey can be customized fully transparent. Track using 2.0mm high-quality galvanized plate internal. Wheel slide is made of nylon can play a good noise reduction. Lightweight and easy to lift. Sectional door is durable, smooth opening and closing, low noise, good sealing safety and reliability. It can also save the space occupied in the plant.
Lifting Methods
There are various ways of lifting an sectional door, depending on the space available at the installation site.
1.Standard lifting
usually applicable to the space above the doorway of about 500mm or so, is the more common lifting method.
2.Improved lifting
usually applicable to the space greater than 500mm above the door opening
3.Vertical lifting
suitable for places where the space above the door head is greater than or equal to the height of the door opening, which needs to have enough height.
4.Low turn lifting
suitable for complex locations with less than 500mm of headroom above the door or where there are obstructing pipes or beams
5.Inclined position turn lifting
suitable for places where the roof has a slope, the door plate can run along the wall with a slope after rising, with strong applicability
Difference between vertical liftgate and turnstile liftgate
1.Vertical sectional doors usually require the torsion spring to be fixed to a central beam, while turning lifting doors fix the torsion spring directly to the wall.
2.Vertical sectional door’s door plate rises without sectional structure while turning sectional door’s door plate will have sectional structure when lifting.
Safety devices for lifting doors
1.Standard bottom airbags
2.Torsion spring safety device, torsion spring adopts 82B spring steel, 60Si2Mn. the surface can adopt Dacromet spray treatment, not easy to rust. Ensure the durability of the torsion spring.
3.Wire rope fall arrest devices
4.End buffers (turn lifts) to prevent door panels from running off the track
To summarize, sectional doors are available in standard lifting, raising lifting, vertical lifting, low turning lifting and inclined turning lifting methods for adapting to many different usage scenarios. People widely usually sectional in different place,such as import and export of factories, logistics terminals, storage warehouses, sand blasting rooms, fire brigades and so on.Due to its flexibility and adaptability, the liftgate has become the choice of very many enterprises.
