electric evolution

JCB has made company history with the unveiling of its first-ever electric excavator – the quietest digger in its range and one delivering zero emissions. The new JCB 19C-1 E-TEC mini-excavator will allow contractors to work inside buildings and in emissions-sensitive inner city environments. Another advantage of the new electric mini is that the external noise, at 7dBA lower, is five times quieter than its traditional diesel-powered counterpart, and with no daily checks of coolant and engine oil levels required, the machine is easier to maintain. “In producing an electric JCB mini-excavator, we are offering our customers a practical and affordable solution for applications that demand zero emissions and quiet operation,” JCB chairman Lord Bamford says. Initially, the mini-excavator will be available with the ROPS/TOPS and FOGS-certified canopy. As the electric excavator is based on…

After extensive development work and thorough field testing, Sandvik is preparing to launch its first Stage V-compliant underground loaders for hard rock mining applications. The base engine and selective catalytic reduction (SCR) purifier are now enhanced with a ceramic diesel particle filter (DPF). As a result of the collaborative product development work, the engine – delivered by Volvo Penta – and Sandvik’s load and haul equipment work seamlessly together to maintain productivity and reliability in the most challenging environments, the company claims. Sandvik says the benefits of Stage V-compliant loaders include a reduced amount of particles in the diesel exhaust, helping mines to improve air quality underground. Additionally, the Stage V loaders are capable of operating with up to 3 per cent reduced fuel consumption compared to the lower stages. Another key enabler for the…

razor the amazer

Perth-headquartered machinery manufacturer Bis has invented and unveiled an underground grader for the coal sector, which has been designed to be safer, more productive and agile. Aptly named Razor, the cutting-edge machine has been developed by Bis’ Tomago-based underground services team, with the grader the first in a pipeline of new innovative products the company has planned for the sector. Bis general manager Mark Doyle says the grader has more tractive effort, increased power, is safer for the operator and has been designed for more uptime. “The concept for Razor started within underground by looking at existing machines and talking to grader operators to understand how we could design a better product – all the way from performance to changing the cab ergonomics to improve comfort,” he says. “Increasing safety was at the forefront…

cooling off

After several years of examining and changing airflow patterns over the radiators of its machines, Komatsu’s new wider-core radiator vanes allow debris to move through the radiator, preventing clogging. “Our brief from customers was to be able to provide them with a full shift of operation without having to stop to clean radiators and coolers of high-density fibres, which gather on the ground in feedlots,” Komatsu national technical manager – wheel loaders Steve Hollins says. The hydraulic fans that distribute air over the machine’s radiator are run in reverse to pick up clean air from behind the radiator and force it forward. The function operates every 20 minutes for three minutes under normal conditions but can be programmed to work for five minutes in every 12 in severe conditions. The ‘reverse cycle’ for the…

Australian company Electric Vehicle Systems and Technology (EVS&T) has developed a breakthrough technology with its patented ultra-low voltage (ULV) electric drive system. At voltages as low as three, the equivalent power of an internal combustion engine can be electrically generated to drive light and heavy mobile mining machinery. The company has installed its drive system in a Toyota Landcruiser to great effect and could be applied to mining machinery very soon, it says. EVS&T spokesman Michael Byford says the safety implications alone of its patented ultra-low-voltage electric drive system are enormous. “It removes the electrocution hazard for operators, maintenance personnel and emergency crews in the event of an accident,” he says. “The need for training personnel to work with high voltage can be removed.” In the mining industry the case for electric-powered mobile equipment is…

We are very confident in these machines and are therefore offering customers a guaranteed trade-back program. Hidromek’s new compact excavators were premiered last year at Intermat in Paris and the highly-anticipated short radius model HMK145LCSR was first to arrive in Australia this year. The HMK145LCSR is part of Hidromek’s new H4 Series excavators that combines power with operating speed for efficient and smooth operations. It weighs in at around 16.8 tonnes, which is slightly heavier than similar models on the market. This is due to the premium build quality of the machine and heavy-duty, reinforced steel structural components. It features the Isuzu AR-4JJ1X engine, Kawasaki pumps, DA auxiliary piping, QH piping, dozer blade and GP bucket as standard equipment. The HMK145LCSR’s climate-controlled, air-conditioned cabin comes with a sliding fold-in front window, advanced colour TFT…
