|Product:||industrial rolling door|
Industrial lifting door belongs to industrial door series, industrial lifting door is also called automatic sliding door, electric sliding door and so on. The thickness of industrial lifting door is 40-50 mm. Industrial lifting door can be used outside every kind of building. It is suitable for medical, food, electronic, printing, supermarket and other factories and areas with high cleanliness requirements, with beautiful appearance, high strength, safety and reliability, stable opening, low noise, good sealing and insulation performance. Because of its low installation conditions and high practicability, it has been widely used because of its remarkable features of saving space occupied by factory buildings and improving production efficiency.
◪ Balance system: the industrial lifting door adopts torsion spring balance, balance torsion spring is designed and manufactured by professional spring factory according to the calculation of the heavy load of the door, which makes the balance reach the best state, and the manual lifting force after the door body balance is ≤ 180N.
◪ Torsion spring material : made of high quality 60Si2MnA spring steel to ensure service life of more than 50000 cycles. The surface is treated by secondary heat-proof, the surface is bright and never rusts. Lifting wire rope wheel, standard lifting door using cylindrical rope wheel. The shaft rod adopts 25mm's 4solid round steel and is equipped with a torsion spring break protection device on the balance shaft, which can prevent the door board from falling when the balance torsion spring breaks.
◪ Sealing:All lifting doors are fitted with top, bottom and side seals, and all tracks and doors are fitted with rubber seals to provide good sealing between the door and the track
Driving principle: use special motor to drive the center axis of the rolling curtain to reach the shutter switch and stop automatically when turning to the upper and lower limit position set by the motor.
Opening speed: average speed can reach 12-18 meters per minute.
Application:It is suitable for the door of the middle and high grade factory building.
