Full Canopy Hangar Doors

Full Canopy

Flexibility

Our full canopy hangar door systems are available in many configurations to meet your specific requirements. Having build full canopy door systems over 20' tall and over 80 reel in width, with wind loads (while closed) up to 200mph, we are confident that we can build a system that will meet your requirements and your imagination.

Design

Doors are designed using CAD and structural engineering software. Door frame structure and connection designs are certified by an independent engineer. Door frames are engineered using structural steel and cold formed members per AJSC and AJSI codes. Wind loads are calculated using your location and building size for the most accurate structural loading possible. We don't make an assumption on the wind load by using an arbitrary standard, we verify every time.

Construction

Door components are manufactured to the highest standards and designed to be completely bolt together, avoiding costly delays due to welding inspections and the availability of certified welders in the field. Door components are also designed to have as few connections as possible, simplifying and increasing assembly speed on the job. This lowers the total installed cost for your door system.

Lift System

Our full canopy doors utilize hydraulic cylinders to lift the door frame. By using hydraulic cylinders to control door movement a large safety factor is gained. Hydraulic fail safe valves are used to lock the cylinder in place if a control valve should fail or a hydraulic line is ruptured or damaged. The geometry of the lifting cylinders is set so that when the door becomes fully open the hydraulic cylinders will be at the end of their stroke This allows the fluid pressure to build and locks the cylinder in position. When the door closes fully the hydraulic cylinder becomes fully compressed, allowing the fluid pressure to build locking the cylinder in place. Door closing speed is adjustable through the factory installed speed control valve. Simply adjust the valve until the door closing speed meets your requirements.

Weatherstrip

Weatherstrip is 1/8" cloth inserted epdm. Weatherstrip meets military specifications for durometer, UV resistance and incidental exposure to paint thinners Retainer bar is fastened by zinc coated self drilling screws every 8" for a secure seal without oil canning of retainer bar. Retainer bar is easily removed for replacement of weatherstripping if it becomes necessary.

Electrical Controls

Door control panels are manufactured in house using only the highest quality UL listed components. Door control systems utilize electromechanical relays that are highly resistant to electrical interference and have no programming that can become corrupted requiring service. Door control systems also utilize solid state proximity sensors for limiting door travel. These sensors are water proof and have no moving parts to wear out Door control systems can be supplied ranging from 12VDC to 600VAC. Variable frequency drives are available for custom tuning or varying of door operating speed. Variable frequency drives come with variable speed buttons with 3 adjustable speed settings standard, 5 speeds as an option.

Standard options

Timer delay with safety noisemaker and/or strobe light, safety edge with delay and/or auto reverse, personnel door frames and safety interlock sensors, explosion proof drive system, air drive operating system, hydraulic drive operating system, electric safety eye, 12VDC backup hydraulic pump, engine driven backup hydraulic pump. Door drive motors and control panels are fully assembled, wired and tested at our facility prior to shipping.
