Big doors for big trucks

Industrial door manufacturer, supplier and installer Maxiflex Door Systems has successfully installed 17 Megadoors at the haul truck maintenance facility, which Kumba Iron Ore built at its Sishen mine, in the Northern Cape.

Kumba Iron Ore, a unit of Anglo American, invested R1-billion in an 8 700 m2 facility to maintain Sishen’s fleet of mining equipment, such as the haul trucks, which were previously serviced outside the workshop using mobile cranes.

Maxiflex Door Systems MD Bram Janssen says Sishen required doors that were rugged and reliable.

“The facility for the haul trucks needed to have positive sealing qualities, due to the extreme environmental conditions of high temperatures and high wind speeds. “The facility needed to be dust free, ensuring better repair and installation of components to haul trucks,” he says.

Maxiflex provided the Megadoor S1000 from ASSA ABLOY Entrance Systems, 16 of which were 12 960 mm W × 10 195 mm H doors, and one 12 960 mm W × 6 766 mm H door.

Janssen explains that the Megadoor S1000 is an extra-large vertical-lifting fabric door, specifically designed for industrial environments where doors are exposed to moisture, dust, extreme temperatures and high wind speeds.

“The unique design and structure offers durability, tightness, energy efficiency, opera-tional reliability and minimum maintenance. “Every door is individually designed to meet application requirements, and can be made up to almost any size. “The doors are resistant to damage and can withstand very high wind loads,” he says.

Maxiflex Door Systems are catering for increasingly large mining vehicles. For the mining industry, it offers the UltraBig and UltraTough Albany high-performance door solutions and the Megadoor vertical lifting fabric doors for commercial buildings, tough environments and very large door openings.

The maintenance facility, dubbed the Life of Mine project, was handed over to Sishen in late 2013. The 28 m × 52 m and 28-m-high building has a total floor size of 8 758.6 m2, comprising the 7 600 m2 workshop, which features 16 working bays of 416 m2, an administrative building with 20 offices, six workshop offices, eight workshop storage areas and a waiting area. The workshop has two overhead cranes on either side of the facility, including one 60 t and three 30 t cranes.
