3D PRINTED EXCAVATOR CAB We’ve featured this 3D-printed excavator cab in the mag before, so we were rapt to see it in the flesh. Part of Project AME (Additive Manufactured Excavator), the sort-of-organic-looking cab was designed and printed by researchers at the Oak Ridge National Laboratory (ORNL) in the United States. The cab formed part of CONEXPO’s Tech Experience area, which explored the kind of tech we’ll be seeing a lot more of in the future. MECALAC 6MCR CONSTRUCTION MACHINE What better way to start the show off than with a stars-and-stripes-flying Mecalac 6MCR multi-purpose construction machine? They’re hard to describe – Mecalac says they’re “crawler skid-excavators”, which doesn’t really help – but basically these amazing machines combine a compact excavator with a compact loader, and can change from digging to skid-steer mode at the turn…

lift your game

We are particularly impressed with the height of the vertical lift Cut and fill for residential construction sites often present some unexpected challenges. Dealing with hard tasks such as removing embedded rock fragments, pulling out old concrete or just plain stubborn hard-packed clay can add unnecessary time to a routine task. Sydney’s Borg Civil didn’t want to have additional equipment on site to deal with some of these challenges, so needed a powerful machine that can deal with the tougher sites it worked on. Already having a fleet of Takeuchi loaders, the company decided to try the new Takeuchi TL12v2 vertical lift track loader, which is an entirely new machine with additional power and a very handy high bucket lift capability. The addition of a rear ripper bar which is monitored by the rear…

head start

The new T94 Series welding helmets from Miller are designed to reduce neck strain and fatigue through better balance, while also improving comfort and visibility. The auto-darkening helmets have a chiselled shell design that provides optimal skin coverage and accommodates half-mask respirators, Miller says, adding that an aluminium heat shield and silver shell reflect heat to keep both lens and operator cooler. The company says it has designed the shell and headgear in a way that provides 14 percent better balance than before, reducing torque on the operator’s neck by 17 percent and alleviating operator fatigue and excessive neck strain. They are also 6 per cent lighter than before. The T94 helmets use ClearLight Lens Technology for better colour and clarity in both welding and light states, which should reduce eye strain and improve…

tough generation

Nine models from the new JCB QS range of mobile generators built to withstand the harshest environments are making their way to the Australian market. The new models are driven by JCB diesel engines that have been tested in around 200,000 machines across the globe. “Each model has three-stage fuel filters and an optional self-cleaning air filter to protect the engine from premature wear,” JCB Construction Equipment Australia (JCB CEA) national product manager Dave Moselen says. “The whole range has been tested and operated to withstand temperatures over 50 degrees Celsius so they can provide non-stop power and performance no matter where they are installed.” The generators are encased in a steel canopy incorporating a single-piece roof that has been dipped in phosphate and given a seven-stage paint process which JCB says delivers…

komatsu collection

Generally we buy our equipment at around the 4000-hour mark. The price suits my market Over the past 12 years, Western Australia-based Lacy Contracting has built a highly successful business around a fleet of used Komatsu equipment. Lacy Contracting is based at Cue, in the state’s Murchison district, 650km northeast of Perth and 420 inland from Geraldton. It carries out a range of contracting and heavy-transport activities for WA Main Roads, as well as the region’s mines, shires and private companies. Activities include major roadworks, civil works, ROM crusher works, mine infrastructure, and heavy haulage. The company is also about to enter the crushing and screening business, having recently purchased two screen decks, and is currently looking to purchase a used BR380JG-1EO Komatsu jaw crusher. Lacy Contracting’s fleet includes 24 Komatsu machines – all purchased…

heart starter

Marvellous what you find when you start “seeing and not just looking”. Recently, on what turned out to be the most productive ‘Ronnie’s Road Trip’ yet, I once again found myself venturing into the bowels of NSW and, in particular, the Blue Mountains. On part assignment and with a bit of time up my sleeve to take in the sights for a change, I found myself in the lovely Blue Mountains township of Lithgow. Now, to some folk that know me, this would not be an unusual event as I grew up there as a kid. I owned a pub there in another life, and it is where I started my earthmoving career as a contractor. That was way back in the early 1970s, when I was working on a major rail line…
