Lifting Hangar Doors

Cronax Vertical Lifting Aircraft Hangar Doors are built to handle the massive dimensions and operational demands of aviation facilities. Designed with a vertical lift mechanism, these doors move straight up, eliminating the need for large side clearances and ensuring maximum use of hangar space. Manufactured from heavy-duty steel or aluminium panels, they provide exceptional durability, wind resistance, and security.

Insulation options ensure superior thermal performance, while integrated sealing systems protect interiors from dust, rain, and extreme weather conditions. Safety features such as obstruction sensors, emergency stop systems, and fail-safe mechanisms ensure secure operation at all times. Powered by robust motorized lifting systems, Cronax Aircraft Hangar Doors operate smoothly and reliably, even with frequent use With their strength, reliability, and precision engineering, make them ideal choice for airports, maintenance depots, and defense aviation bases.

CUSTOMIZATION OPTIONS

Door Type	Vertical-lift, fabric or rigid-panel aircraft hangar door designed to move straight upward, folding or stacking into the overhead header for a clear, unobstructed opening.
Primary Application	Aircraft hangars, shipyard bays, aerospace facilities, and other large-span buildings where lateral sliding is impractical or side space is restricted.
Maximum Clear Opening	Unlimited width and height in modular configurations; fabric versions allow spans over 35 m, while rigid panel versions can exceed similar dimensions.
Operating Speeds	Standard speeds ~0.20 m/s (20 cm/s), with optional fast-cycle motors up to ~0.40 m/s on select systems.
Construction & Mechanism	Flexible doors made from heavy-duty PVC fabric pleated upward, reinforced by horizontal beams; rigid doors employ multiple hinged leaves guided upward.
Structural Components	Vertical aluminum or steel guide rails; bottom beam engineered for wind-load sealing; intermediate beams retract electrically and include wheels for smooth movement.
Environmental Resilience	Fabric rated for high wind loads (up to hurricane levels); fabrics fire-resistant per DIN 4102-B1; rigid options offer enhanced insulation and durability.
Compliance & Standards	Manufactured per EN 13241-1, CE-marked; performance-tested for wind, structural, and safety criteria.

Drive System	Dual motor-electrical winch (belt or wire rope) or hydraulic drive systems; balanced lift ensures smooth, synchronized operation and redundancy.
Power Supply	Options include 230 V single-phase, 400/415 V three-phase; emergency generators or UPS available for uninterrupted access.
Control Panel	PLC-based controls with soft-start, limit-switch positioning, diagnostic display, warning lights, and alarms.
User Controls	Push-button (Open/Stop/Close), optional touchscreens or remote-control interface, with “dead-man” mode and safety interlocks.
Safety Systems	Load arrestors to prevent drop in cable failure, wind locks to keep doors secured during high winds, photo-cell detection, and automatic reverse logic.
Emergency & Backup	Manual hand-crank override and generator or UPS for operation in power loss situations.
Integration	Seamless compatibility with hangar BMS, external lighting, fire and security systems.

Fabric & Panel Materials	High-strength PVC fabrics (900–1500 g/m²) with UV and fire resistance; rigid panels constructed from insulated steel or aluminum sandwich materials.
Sealing Packages	Bottom cellular rubber or brush seal; tight vertical guide sealing; top header seals ensure complete closure even under wind pressure.
Options & Accessories	Vision panels in rigid doors, branding or warning graphics on fabric, customizable RAL finishes, runway lighting, side hoods, or wiper doors for personnel access.
Insulation & Climate Control	Rigid versions offer U-values as low as 0.57 W/m²·K; fabric versions available with optional thermal cladding.
Maintenance	Designed for 24×7 operation with minimal maintenance; fabric doors notably lightweight, corrosion-resistant, and easy to service.
Customization	Modular multi-leaf designs, width/height configurations, smart monitoring systems, and tailored engineering for site-specific loads.
