Automatic Large PVC Fabric Flexible Rolling up Doors Lifting Fabric
Hangar Doors For Aircraft
Features:
1.Surface is PVC fabric, double layer and beautiful.
2.Main skeleton is formed with steel tubes. It is designed through
precise structure calculation with universal steel structure
software, meeting requirements of wind resistance.
3.Safety Drop-proof device, can stop falling of door body when the
steel wire of motor breaks suddenly, protecting human life under
the door.
4.Multi-limit design guarantees precise running.
5.Inching control design makes sure there will always be a human
operating the door when it runs. This can avoid accidents caused by
human-absence.
6.High safety class of motor and steel wire, guarantees reliable
operation.
Applications:
Shipyard, blasting or painting room, hangar, and large machinery
factories.
