Hard fast-roll door is suitable for all kinds of high-pressure, anti-wind and high-speed separation areas in the outer door, inner door, passageway door and factory building. The specific use departments are logistics area, assembly workshop, paint painting workshop, body workshop, stamping workshop, engine workshop, etc.
• Power systems:
Using SEW motor and frequency conversion control system, power 0.75~3 kw.
Servo system motor and servo closed loop control system, power 0.75 kw~2.2 kw
• Control system:
High performance upgrade control box is adopted, which has the characteristics of high performance, high reliability, high stability, high precision positioning and so on. At the same time, it also has the function of soft start and slow stop to ensure the smooth operation of the door body and increase the service life.
• Track:
Spiral track, synchronous lifting, non-coiling shaft roll up, easier to balance, door plate under the lift drive along the spiral track quickly rolled up, zero contact between the door plate; the door plate is equipped with polymer pulley at both ends, It has no contact with each other. The two ends of the top drive shaft of the door are wear-proof spiral integral track. After the door plate is rolled on the top, the door plate is not in contact, does not rub, and the door plate will never wear.
• High strength spring balance system
Use spring to balance the weight of the door. The strong lifting belt connects the door plate with the high strength tensile spring group to prevent the sudden fall of the door plate in case of failure. In addition, during the door opening process of the door plate, the spring fixed on the ground and the connected hidden lifting belt also provide support for the driver, and the handle door can still be opened safely when the power is cut off.

The door plate is double side color coated aluminum roll, the interior is filled with polyurethane insulation material, the standard height is 195 mm, the connection is treated by broken bridge, the thickness of the door plate is 40 mm.
• Windows:
Double side acrylic transparent window, no wear, no aging
• Sealing performance:
Sealing strips are arranged around the door body to ensure the sealing of the door body.
• Safety performance:
Infrared security: each door is equipped with a photoelectric protection system to prevent the door from falling against pedestrians or vehicles.
Airbag: each door is equipped with a bottom airbag, in the process of rolling door drop obstacles can make the door body reverse operation, to avoid damage.
• Light screen (optional): powerful safety detection function, wide coverage, more comprehensive protection.
