The work processes in an aircraft hangar are very demanding and require maximum organisation, efficiency and reliability. These requirements have to be fulfilled and Butzbach offers full support to master this task.
We support you right from the start in all planning considerations. We advise you on the size and position of your hangar door as well as on the opening principle, type of drive and choice of filling material. We take your safety equipment and architectural design aspects into account. Our specialists are your competent partners for all questions concerning the conception and planning of your hangar door.
The Butzbach unique bottom tracks control the exact movement of the door leaves. The loads, from wind and the door leaf weight, are transmitted directly into the bottom track foundations. Any incidental rainwater is discharged from the bottom tracks into connected drainage. An optional rail heating system can be integrated, to meet customer additional requirements.
Due to roof deformations over the door system, tolerance clearances (girder movement) must be created for the compensation. Hangar door systems standing on the bottom tracks consider the girder movement (specification of the static calculation) above the door system.
Safety edge devices have the function of ensuring personal safety on the leading edge of a door leaf. During the operation of the door leaves, there is a non-visible protected area in the direction of motion, which can represent a danger to persons and/or objects. Touching the safety edge device triggers a command that stops the door leaf and initiates a reversing return movement.
The installation of vertical tail gates as stacking doors in the structural replacement of the door truss reduces the main door height and therefore costs. For the vertical tail door we use our own produced fiberglass and create a uniform appearance to your hangar door.
Door motors are used to move heavy door leaves. Electric geared motors with a chain connection to the drive wheel are in use. The door leaf is set in motion via a push button drive switch and the necessary electrical control.
One adjustable pendulum brake is installed in each door leaf (manual operated door system), in order to protect the personnel and material. This brake has no negative effects on the manual force when opening or closing the door leaf with a speed up to approx. 0.30 m/sec.
The pendulum brake stops the door leaf when the above-mentioned speed is exceeded (without any electrical influence). Once the door leaf stops, the brake will release automatically and the door leaf can either be opened or closed.
