2254 Dana Rexroth’s HVT R3 is a hydro-mechanical variable transmission for wheeled loaders with engine outputs of up to 265kW and is the first power split transmission from the joint venture between Dana and 2253 Bosch Rexroth
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.
Cat’s latest E-series excavator is the 16.7tonne 316E. It replaces the 315D and gets a Cat C4.4 Acert engine to meet EU Stage IIIb emissions. It is the first of three smaller E series being launched by Cat this year. Electric boom regeneration is also available on the new model, and combined with the latest engine technology, gives the company a fuel-saving focus. There is a new cab with lower noise levels – typically a 4dB(a) reduction over its D series predecessor – and improved comfort and visibility too
Doosan’s new Stage IIIB-compliant DX300LC-3 and DX340LC-3 crawler excavators are said to offer 6% to 17% higher productivity, along with fuel saving and reduced costs. The 30 and 35tonne machines have a new ROPS and OPG-certified pressurised cab. A heated air suspension seat and a new cab suspension cut vibration by 20% and reduce the sound level in the cab to 71d(B)A.
