tidy two-tonner

In the tightly contested two-tonne zero-swing excavator market space, there are quite a few options worthy of consideration. Chief among them is Bobcat’s new E20, which features dual-flow auxiliary plumbing as standard, enabling bi-directional attachments such as augers and tilt buckets to be utilised. With a line-up of attachments developed specifically to match the designed capabilities of Bobcat equipment, the E20 is versatile. Unlike many other OEMs, Bobcat has focused on the smaller end of the market, and has only ever particularly produced hydrostatically powered machinery. The Bobcat E20 is loaded with features. The undercarriage is longer than its predecessor, therefore making it more stable. It also features a hydraulically widening undercarriage system, enabling the E20 to be retracted into a 991mm width configuration to access tight areas such as doorways and gates. Once you’re on…

caterpillar in 3d

Earthmovers & Excavators magazine went out to check out Mick Sheldon’s new 320 3D, which is hard at work on a new residential subdivision just off the M1 at Holmview in Queensland. “We have the access hire business, the earthmoving business, and the haulage business, and also now repair machinery, so we have a lot going on,” he explains. On the hot topic of his flash new Cat excavator Sheldon couldn’t be happier and neither is the operator he hires out with the 320 3D. “These excavators are five years ahead of the other players in the marketplace really in terms of technology,” he says. “Cat dealer, Hastings Deering, is partnering with Sitech, who are the leaders in global positioning equipment for machine control, so now you can buy the Cat 3D machines off…

turkish delight

Turkish brand Hidromek has entered the Australian construction equipment market by partnering with Onetrak. The Hidromek HMK 600 grader has a high-performance Mercedes Benz OM926 diesel engine which provides excellent efficiency and fuel economy even at lower revolutions while generating power at a range from 140kW to 160kW. Possible tyre skidding and abrasions are minimised by generating optimum power in low gears. Variable horsepower increases the performance of the machine by about 12 to 15 per cent compared to the previous model and performs well in conditions and on all terrains. All blade and attachment movements are controlled by an advanced electro-hydraulic control system in the HMK 600MG. At the centre of this closed-loop system is a 10-segment, solenoid-controlled, main control valve with load-sense feature, supplied by a variable-flow piston pump. One of the important features…

dumper of the future

Wacker Neuson has revealed the DW60 dual-view concept for wheel dumpers that allows an unobstructed view in every direction. Showcased recently at Intermat 2018 in Paris, the new range of wheel dumpers will have the ability to carry anywhere from six to 10 tonnes. Dual view allows the operator to conveniently and quickly change the seat position through a 180-degree rotation of the entire operating and seat console. This always gives the operator a perfect view in the direction of travel – during transport, loading and dumping. This is especially useful on small confined construction sites, in urban areas, in tunnels or on busy roads. After loading or unloading, a 180-degree rotation of the seat allows the operator to drive away the same way they came in, with a full field of vision…

swedish quarry goes green

The system, which incorporates electric and autonomous Volvo machines, will run in a real production environment for 10 weeks – delivering an anticipated 95 per cent reduction in carbon emissions and 25 per cent reduction in the total cost of operations. Drawing on the electromobility and automation expertise of the Volvo Group, the research project, dubbed “Electric Site”, aims to electrify each transport stage in a quarry – from excavation to primary crushing, and transport to secondary crushing, although a small amount of diesel power will still be used. The system’s efficiency, safety and environmental benefits are set to impact both customers and society at large. Volvo CE and Skanska began testing the Electric Site concept at Skanska’s Vikan Kross quarry, which produces aggregates for construction purposes as well as for asphalt and…

efficient operators

Komatsu has introduced a Tier 4 grader, which it claims cuts emissions and fuel consumption while increasing safety and durability; along with two new ‘Dash 8’ rigid dump truck models equipped with low-emissions Tier 4 engines. GD655-6 GRADER The GD655-6 boasts features that improve fuel efficiency, safety, durability and reliability – while retaining its class-leading high-visibility cab and unique lock-up torque converter transmission system. Powered by a Komatsu SAA6D107E-3 Tier 4 Final-compliant variable horsepower engine, rated at 134-165kW (depending on gear and operating mode), the model has an operating weight of 18.9 tonnes with rear ripper. Compared with its Tier 3 predecessor, it reduces both particulate matter (PM) and nitrous oxide (NOx) levels by 90 per cent, while reducing fuel consumption by up to 15 per cent. All Komatsu Tier 4 engines incorporate an…
