Mining Hangar Door

Mining hangar doors

Shipyardoor® is customised mining hangar door, for truck shop facilities for Open-pit mining. Mining industries has very special requirements, big truck of mining is operated 7/24 hours, it is never stop, minimum 2 times at week need maintenance, truck and wind bring dust, fill every gap also damaged everything in workshop, snow storm at 4000 mt frozen everything, mining industries preferred the truck shop is movable. All this conditions is required very special engineered door solutions.

During design of the Flexible Giant Mining Hangar Door all this requirements is specially observed and door performance enhanced  according to industry requirements with client feedback, high level insulation, less gap, no ball-bearing, easy install-reinstall is adopt our system for special mining industries. This hangar doors is designed for simple and robus.

Shipyarddoor® Mining hangar doors have been using from Mexico to Australia. We change everything that mining industries know about hangar door, so our success is a not a coincidence. As the Jim Rohn said Success is nothing more than a few simple disciplines, practiced every day.

Steel Structure

Steel Structures

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. Thickness of the doors improve door sealing properties also durability in windy conditions. The beams have special choose polyamide tires for easy operations at windy conditions. That tires have self lubricant properties cant be effected from dust filling or similar outside conditions. The intermediate beams when retracted don’t impede the clear opening dimensions.

Bottom Beams

Bottom Beams

Bottom beam is designed according to wind resistance, dimension of the doors and, to carry load of intermediate steel beams during door operations. Bottom beam also supply full closing and sealing in heav y wind conditions.

Side guides

Shipyarddoor Flexible Giant® mining hangar door w vertical guides are made of structural steel with a suitable depth and width depending on the size of intermediate beams. Guides are designed to provide weather-sealing between door and door frame. Side guides are designed and manufactured for easy replaceable in case of damage. Aluminum rails are fixed with bolt to steel structure.

Side guides

Cable System

Shipyarddoor is operated with steel cable, maximum of two cable each doors 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.

Sealing

The bottom beam is furnished with cellular rubber seal (U-Shaped). The side guides on frame structures or mullions have either cellular rubber seals or integral brush seals depending on door type. Specially selected rubber has high resistance against for outdoor conditions extreme cold and hot weather.

Sealing

Fabric

Specially choose fabric is suitable for long life. 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. We uses most resistance fabric in fabric hangar door business. . We also have Arctic Fabric for extreme climatic conditions-Secure and Sound Resistance fabric is available as a options.

Fire Resistance

Fire resistance is one of most important requiments in mining applications Our standard doors fabric has flame retardancy properties according to Relative Standard is DIN 4102-B1.These materials are difficult to ignite. They include materials such as wood treated with a fire retardant and rigid foam plastics. A fire must extinguish itself when the source of the fire is removed.

Speed

Mining Hangar Doors are operat ed at a standard 20 cm /se c opening and closing speed and can be increased up to 40 cm/sec.

Insulation Data

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

Load Arrestors + Wind Locks

Wind Lock Arrestors

Shipyarddoor Flexible Giant® (with steel trusses) are equipped with load arrestors attached to bottom part of door.(Patent Protections) Load arrestors will prevent the door from falling down in case of motor or lifting strap or rope failure. Wind locks will prevent door rising up from its close position even in very windy conditions. Load arrestors safety device is sense a slack cable condition and cut power to appropriate (it is combined with switch
system. Drive unit to prevent an unsafe condition.

Wind Resistance

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.

Structural Loading

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.

Driving Unit and limit switches

All driving units and component choose for resistance of extreme conditions in Mining area .The lifting motors are normally located above the door opening. All Shipyarddoor hangar doors are equipped with double motor to supply balanced uplift and even though if 1 motor damaged other 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.

Safety

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.

Color

Wide range fabric color is 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)

Control panel

Control board is designed according to CE 2006/95 EC and to NEMA ICS 6, Standard. İt is specially designed for simple and high durability. It is also designed easy replace and maintenance components. Control Panel dosent has expensive circuit diagram plc or similar equipment. It is designed for heavy duty jobs. As a part of safety regulations Control panel contain interlocks to preclude personnel injury, key lock for authorized personal operations includes an interlock between the power supply system and use of hand crank for manual operation of door unit. (Optional) It is controlled by momentary pressure to open and constant pressure to close, also Dead-Man mode is available. 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.

Control Boards

Operations

Shipyarddoor® Flexible Giant Mining 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.
