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.
Sandvik Mining is now using Volvo Penta engines in its underground trucks and loaders. The advanced engines meet Tier 4 Interim/Stage IIIB emission standards and are claimed to reduce fuel and ventilation costs in comparison with other units. The Volvo Penta engineers designed a selective catalytic reduction (SCR) unit in the exhaust system that converts NOx gas into nitrogen and water. The Volvo Penta exhaust-treatment solution also reduces DPM levels without the need for a diesel particulate filter (DPF).
Opposite in the size scale to Merlo’s other Intermat 2012 machines, the ‘Grand Roto’ 60.24 MCSS and the 40.30MCSS, is the tiny P25.6 SuperCompact telehandler. Only 1,800mm wide, the P25.6 is said to fit into the smallest of site applications. Although being small aids manoeuvrability, Merlo says this has not led to a compromise on cab comfort. The machine’s cab is said to have exactly the same 995m size as all the other Merlo machines. Merlo claims that, unlike many other compact handlers, the P25.6 has exc
