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.

With working heights ranging from 14metres to 23metres, the five JLG Compact Crawler Booms feature a tracked wheel carriage and a narrow chassis for access through gates, yards, standard doorways and public buildings. The compact crawler booms are said to be low weight units drawing on an environmentally friendly combination of electric and combustion power for efficient energy use.

Using Ammann’s AS1 plant control system, the EcoMix concrete plant combines accurate measuring equipment and comprehensive process control to guarantee perfect, repeatable results, claimed Ammann. The galvanised steel support structure is light, warp resistant and also suitable for areas of increased seismic activity, it is claimed. The EcoModule is equipped with the company’s tried and tested Amix twinshaft paddle mixer and is pre-assembled and tested at the factory.
