Product Description
Emergency Manual-Operation Industrial Sectional Overhead Door For Power-Critical Facilities
An Emergency Manual-Operation Industrial Sectional Overhead Door ensures continuous access during power outages. When power fails or motor malfunctions occur, the door can be manually opened using a chain hoist, guaranteeing uninterrupted passage for personnel and vehicles in power-critical facilities.
Access That Never Stops
The emergency manual operation feature is integrated into the door's balance and drive system. A manual hoist chain and emergency release enable operators to raise the door by hand during outages, ensuring facility entrances remain accessible. The torsion-spring counterbalance minimizes manual effort, allowing reliable operation by a single person.
Key Advantages
- Manual Opening During Power Failure: Maintain access and emergency operations when power is lost or motor faults occur
- Low Manual Effort: Torsion-spring balance system reduces opening force to approximately 140N for easy hand operation
- Reliable Emergency Release: Dedicated emergency release and chain hoist enable quick and straightforward manual mode switching
- Strong and Insulated Build: Reinforced insulated panels ensure durability and energy efficiency during normal automatic use
