Mine doors for tough conditions in coal terminal /global/scaled/3872x1685x0x343x1000x435/AAES-US-case-studies-images-rg-tanna-mining-3872x2592px.jpg The installation of mine doors to withstand the tough workload and harsh weather conditions with very strong winds also increases the working space at RG Tanna Coal Terminal in Queensland, Australia. The need for a safe and secure door led to a solution where an original steel frame was retrofitted with new Megadoor mine doors from ASSA ABLOY Entrance Systems. The installed Megadoor mine doors, each 11.8 meters wide x 8.0 meters high, provide safety for heavy equipment maintenance personnel, and contributes to improved working conditions for staff while increasing working space. Withstanding heavy wind loads One great benefit is the ability to withstand really heavy wind loads. Our hangar doors are resistant to high winds and hostile environments with a fabric that could withstand at least 4.0 kPa wind load. The installation with connecting hangar door systems means that each door can be used independently, but also allows maximum opening.
