Paired with a high-torque rapid door motor, the system delivers steady, quiet cycles even under heavy use.  Safety and sensing Install loop detectors, radar sensors and photoelectric switches to protect people and vehicles. These sensors react quickly and integrate with the control box to stop or reverse the door the moment an obstacle is detected.  Motion and position Encoders provide precise position feedback for accurate opening heights and smoother stops. Reliable reducers and gearboxes ensure long life under frequent cycles.  Sealing and reinforcement Reinforce strips and guide brushes improve wind resistance and reduce wear. For better sealing, add a sponge door seal at the bottom edge — it’s an affordable upgrade that improves energy performance and keeps dust out.  Spare parts and service We stock common wear parts for fast replacement.
