Bi-Parting Automatic Aircraft Hangar Door Systems
The bi-parting configuration of our Karen aircraft hangar doors is the most popular and probably the style of hangar doors that comes to most people’s mind. The doors open from the middle and can have anywhere from one section to five door sections on each side. Each leading door section has an electric motor drive system that is mounted internally. The non-powered door sections are interconnected to the leading door section using a bumper pick-up system. When open, the door sections stack in the two side corners of the hangar. Pocket space is determined by the number of sections.
Instead of the door sections opening to each side like the bi-parting system, the unidirectional aircarft hangar door system opens in just one direction, either to the left or to the right. The up-to six sections are controlled by an electric motor drive system that is mounted on the leading door section. One advantage this system can have over the bi-parting system is that only one corner is needed for pocket space vs two.
Architectural flexibility is once again awarded here as multiple configurations are available. Each door section is bottom rolling and top guided.
Configurations include: uni-directional, bi-parting, individually operated, 3-way traveling group and anchored group systems.
These options allow you to choose what will best fit your needs. With the Karen system, there is also the choice of bumper pick-up or cable-reeving opening and closing system. Karen automatic hangar doors are an excellent application for corporate, FBO, charter and airline hangars. By working closely with architects, contractors and owners, we can manufacture a system that meets your specific needs or can retro-fit to meet the needs of an existing structure.
Karen Motorized hangar doors are manufactured in sizes up to 50 metres W x 15 meters H. True telescoping top roller assemblies can be fabricated to tolerate almost any header deflection requirements. The factory-installed, dual opposing bulb vertical weather seals provide dramatically superior sealing in comparison to single or dual-flap weather seals. Internal wiring to the powered door section is completed and tested at the factory.
Plus, no release of the electric motor shaft brake is required. The electric motor single-lever disengage completely separates the motor drive assembly from the drive wheel for non-powered operation. The draped S/O cord is equipped with looped thimbles factory set to match up with cord hangar brackets.
Top guides and quick set bottom rails are shipped in factory-fabricated sub-assemblies with bottom rail forms included in every project. The bottom rails are grouted out around the rail head. Additionally, to offer quick assembly and straightforward installation, door sections are delivered to jobsite in factory-fabricated, sub-assemblies.
The Karen hangar door system is built to endure massive wind loads and withstand strong weather conditions. The poly foam filled vertical weather seal bulbs offer the tightest, most reliable all-weather protection allowing for long-lasting performance reliability. A stable operating movement is maintained due to the quality of the bottom rails and the top tracks using telescoping top roller assemblies.
