HANGAR DOOR

Doors are made of two fabrics folding in opposite directions. Fabric sections are fastened to horizontal beams (Steel or Aluminum). Minimum door thickness is 600 mm. Intermediate beams are retractable by an electric motor. The beams have tires for easy operations at windy conditions. The intermediate beams when retracted don’t impede the clear opening dimensions.

Shipyarddoor is operated with steel cable, maximum of two cable each door that are running inside the guides. Cables are installed free of any kinks and sheave diameter is chosen carefully to prevent any occurrence of kinks or abnormal stress while operating cables.

Special fabric is suitable for a long time. It has very high resistance against to UV damage, VALMEX POLYMAR ® Industrial Fire resist 900-1500 gr/m2 2 mm 1100 Dtx B 6000.Tensile Straight 4300/4000 N/50 mm DIN 53354. Tear Strength 500/500 N DIN 53363.

Fire resistance of the fabric is suitable for any fire safety regulations. Relative Standard is DIN 4102-B1. To ignite these materials are very difficult. They include materials such as wood treated with a fire retardant and rigid foam plastics. A fire must be extinguished by itself when the source of the fire is removed.

Standard Shipyarddoor Flexible Giant fold up hangar door has excellent insulations due to extreme width and sealing properties. Thermal insulation value is U<0.9 W/m2.K Insulated fabric has also Sound attenuation 12 dB A.

Shipyarddoor ® hangar door is designed as a unitary system to withstand wind load specified. Fiber stresses due to combined dead load and wind load will not exceed factors for material being used and type of loading sustained, operationally 140 km /h also at closed positions can be stand up to 180 km/h. Special doors can be manufactured with wind speed bearing capacity up to 230 km/h for hurricane region.

Shipyarddoor® hangar door is designed to withstand dead load, seismic forces and design loads due to pressure and suction of wind calculated in accordance to environmental and building ambient.

Hangar Doors are operated at a standard 20 cm/s opening and closing speed and can be increased up to 40 cm/s.

The lifting motors are normally located above the door opening. All Shipyarddoor hangar doors are equipped with double motor to supply balanced uplift because when one of the motors is damaged other one can operate the system. The limit switches are also located above door opening. Shipyarddoor switch system doesn’t miss or damage, all switches are located both sides with safety switch. The door stops on the limit switch when the door is completely opened or completely closed. Should the doors by-pass these limit switches there are also safety limit switches in both directions. In upward direction the limit switches are located above door. At each end of door and topmost moving horizontal door beam will activate them. In downward direction limit switches are located above door opening on slack strap/rope switches.

Doors are manufactured according to CE Standard. Applicable Directives 89/106 /EC-99/93/E Applicable Standards:- EN 13241-1:2003+A1:2011-EN 12978:2008 and Load Arrestors ,wind lock , thermic resistance, buzzer and warning light is served as a standard 
Optionally: Bottom safety edge and pneumatic safety edge system is available.

Wide range fabric colors are available. All main color at our stock (RAL 9002-9006-1001 -3001 – 5007-6001-7071) (some color is out of stock can be extend delivering time)

Shipyarddoor® Flexible Giant fold up fabric hangar door is guide up and down with weather sealing vertical guides attached to the structure. Door is controlled by three buttons marked “Open,” “Closed,” and “Stop.” Audible and visual warning devices is started automatically signal for a few seconds before any door section movement, remain continuously on while the door is in motion and reset immediately after movement stops.

Manual Operations;

There are a few ways the emergency operation could be accomplished.
- A hand crank that attaches to output shaft of the motor is available for manual operation. In cases of very large doors, this is not a feasible way of opening.
- Connecting the door to a power generator would eliminate the problem in case of a power failure.

Control panel also contain -Frequency converters, Safety Edge System. PLC Controller with touchless button in special case. Control panel can be fed from an automatic transfer switch which will supply emergency power to the door system in case of a power failure.
