Using a combination of hydrostatic and mechanical drives, the technologically advanced three-range transmission can offer up a fuel saving of up to 20% by delivering a stepless speed range from 0-40km/hr without clutches and without interrupting the drive.
Cleverly, the HVT R3 will allow the operator to preset a maximum travel speed, or preselect a fixed engine rpm and use the transmission’s characteristics to keep the engine working at its most fuel-efficient point.
The DT12 crawler-mounted dumper can work as a self-loading unit to dramatically cut loading times while boosting efficiency, according to its manufacturers Wacker Neuson.
Simex has introduced a visual indication on its planning attachments – the Performer – which enables operators to utilise all a carrier machine’s available power while avoiding stalling. The patented system automatically resets to reflect each machine’s maximum power and, according to the company, the device typically improves production rates by 25 to 30%.

Italian foundation specialist Soilmec has added two rigs to its piling range. The SF-65 replaces the previous SF-70 and answers customer requests for added versatility. The continuous flight auger (CFA) rig allows operators to drill all around the machine without having to relocate the tracks to bore at the corners as before. Powered by a 205kW diesel engine, the SF-65 can handle 1,000mm diameters to a depth of 27m.
