59 PRODUCT NEWS Wheel loaders Case Constr uction Equipment has developed two new wheel loaders in its F Series range. The 27-ton 1121F and the 24.6-ton 1021F (which replaces the 921E) are suitable for quar ry and aggregate applications. The 1021F has an operating load of more than eight tons, while the larger 1121F has an operating load of around nine tons. Both feature a 4.8 cubic metre bucket that can be controlled with the Case Ride Control System. Both wheel loaders also feature nine-litre engines that are cooled by a 'cooling cube system'. Rather than overlapping radiators, the cooling system is box-shaped, with each radiator forming a side. Combined sweeper/scrubber Rosmech Sales & Ser vice has released a compact sweeper and scrubber designed for cleaning footpaths, car parks, shopping precincts and bike paths. The Azura Flex incorporates features from the original Azura sweeper and the Aquazura scrubber. The unit is equipped with a hydraulic lifting system that is compatible with a range of attachments, such as a third br ush (which increases the sweep width to 2700 millimetres), a high-pressure water spray bar, a three-br ush scr ubbing head with a 20 litre detergent tank, a snow plough, a snow br ush or a salt/grit spreader. Short-tail excavator Komatsu Australia has released a 10-ton wheeled short-tail excavator that has three different steering confgurations. The Pw98mr-8, part of the mr-series, has been designed with two-wheel steering for normal travel, four-wheel steering for manoeuvrability, and ‘crab-steer’ for movement in confned areas. It also has a short ‘tail-swing’, which reduces the turning radius and allows work in tighter spaces. The unit is powered by an interim Tier 4-compliant Komatsu SAA4D95LE-5 ecot3 diesel rated at 50.7 kilowatts and features a two-speed hydrostatic transmission that allows speeds of up to 30 kilometres per hour. The unit comes standard with a 1.65 metre arm, a dozer blade and independent rear stabilisers that are controlled from the LCD monitor panel.
