Developments in new technologies, agricultural machinery, bigger and bigger storage buildings are constructed, hangars, which needs to close entry-exit gates, to protect property from the weather conditions. Whatever that is, hangar for the industry, building for agricultural machinery or any other commercial project. Decision is clear – BIFOLD Hangar doors.
Basic structural and functional components of the hangar doors:
- Leaf frame (1)
- Hinges (2)
- Side door locks (3)
- Truss (4)
- Bearing mounting plates with bearing placing section (5)
- Lifting belts and rolling drums (6)
- Shaft (7)
- Electromechanical transmission (8)
- Supporting bearing (9)
- The control unit (10)
- On-off switch (11)
- The safety and warning devices;
- Panel – heat insulation (12)
Door operation principle
While holding the door on-off switch, which is located on the control unit, electromechanical drive loosens shaft, cables became loose and lifting belts allows the doors to move slowly downward. After landing, side locks presses and fixates doors to the building , thereby ensuring the security and stability of the gate.
Whole doors perimeter is sealed with rubber. Because of the dense, doubled rubber seal with the cloth inside, doors becomes resistant to any weather conditions!
The chain drive motor located in the aid, in case of power failure or breakdown of the door electromechanical actuators can lift or lower doors manually. For such situations there is dedicated emergency release lever and emergency lifting chain.
