49 PROMOTION New sweeper ticks all the boxes Capable of operating in wet or dry environments, including highly polluted urban areas, the Hako Citymaster 1250 City Cleaner meets the high standard of footpath and street cleanliness required by most Australian councils. Designed to be an articulated sweeper, scrubber, mower, mulcher and more, the machine requires only minutes to change from being a high perfor mance suction sweeper to a large capacity footpath scr ubber. The 1,300mm scrubbing deck ensures all debris and water is picked up immediately, leaving the surface ready for pedestrians to walk on. The new unit, with others in the range, will be launched during the public works expo CIVINEX at Sydney's Eastern Creek in May. Hako says, with its extraordinary suction, power and articulated design the Citymaster 1250 City Cleaner offers manoeuvrability and performance around footpath obstacles and in restricted spaces, ensuring thorough cleanliness on cycle paths, footpaths and roadways. Packaged pump system aunts convention A packaged service water pumping system from Gorman- Rupp is said to be more cost e ective than conventional approaches according to Australian distributor, Hydro Innovations. These systems provide service water within the plant for screen cleaning, general cleaning and wash-down, using treated water from the plant. The conventional way to provide this water according to Hydro Innovations representative, Garry Grant is with either a standard centrifugal pump or submersible pump system. He says with the standard centrifugal system, the pumps need to be located below water level, which generally requires a below ground pump station with above ground building, inclusive of stairs, isolation valves, a sump pump, lighting and ventilation. Operators then need to enter the building, go down stairs and isolate pumps to access and service them. "With a submersible pump system, a building may not be required, but a wet well will need to be built, inclusive of discharge elbow connections, guide rails, li ing chains and some kind of winch to raise the pumps when servicing is necessary," said Grant. "This may be a cheaper option for the civil costs, but any time pumps need to be serviced, wet well lids need to be opened, pumps need to be hooked up to the winch and raised to the surface. So this system is more labour intensive and increases OH&S risks." The new alternative according to Grant is a Gorman-Rupp packaged self priming pump system. "Because pumps can operate on suction li s to 7.5 metres, the pump station can be located at surface level in a small self-contained breglass building," he explained. "The civil costs are substantially lower, and the stations can be tted with reliable Gorman-Rupp 80 Series or Super U Series pumps, delivering pressures required for service water applications." When it comes to maintenance, the Gorman-Rupp systems can then be accessed from ground level, do not require li ing equipment, and are easily monitored and serviced. Grant also says that because capital costs and maintenance costs are lower, the total cost of ownership is much lower than a "conventional" system For more information call 02 9647 2700 or contact firstname.lastname@example.org Stabiliser equipment delivered The frst Stehr SBF 24 soil stabiliser and SBS 3000 spreader ordered by an Australian customer was delivered by Broons in January. Goulburn-based Divall Earthmoving & Bulk Haulage received the item, which is said to be ideal for harsh operating conditions. A further six units will be delivered to Australian clients during the frst quarter of 2013. This particular stabiliser and spreader features a 2.4-metre working width and is capable of operating to a depth of 600 millimetres. Broons also offers three other Stehr soil stabilisers with mixing widths from 2.2 metres to 2.4 metres and a working depth of 400 millimetres to 600 millimetres. The range includes either a straight soil stabiliser or the computer- controlled SBF 24-6 integrated spreader/mixer. According to the company, in-situ soil stabilisation, with the addition of lime, cement or fy ash, can turn problematic soils into a high- quality compactable material on the spot. It provides an improved resistance to water penetration and frost damage, reduces expansion and contraction, and improves density and sheer strength.
