Austin Engineering recently delivered Australia’s largest water tank to an open pit coal mine in Queensland’s Bowen Basin.
Designed and manufactured by Austin Engineering, the Stairway Access Tank (SAT) has an innovative stairway that improves access for maintenance personnel and, inside the tank, a corrugated baffle design that reduces surging to improve truck stability by up to 18%. The result is increased operator and site safety.
Custom-built to suit either 170mt (190t) or 220mt (240t) class haul trucks, the new Austin SAT features large access ports in the baffles, giving a direct line of travel inside the tank.
Along with improving safety this unique feature also reduces costs and increases access and manoeuvrability for personnel and equipment inside the tank when performing confined space maintenance work.
Additionally, to improve the worksite environment inside the tank during maintenance periods an air exchange system has been included in the design.
A large fill port, that incorporates a trash screen, is located in a recessed channel behind the water dam and the tank bottom has a natural sump for ease of cleaning and tank draining.
