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.
Bonfiglioli Trasmital has developed a new series of travel drive gearboxes for use in large, heavy duty tracked machines. The firm is now offering three new product sizes, the 722C, 724C and 726C, which extend its range of tracked travel drives. The 722C develops a maximum torque of up to 330,000Nm, making it suitable for use on excavators of 120-150tonnes, as well as cranes and drilling rigs of 180-230tonnes. The 724C develops a maximum torque of up to 450,000Nm, and is specially designed for large cranes
Berco’s display includes its Robustus rotating bushing track system, which is designed to reduce friction and wear for a longer undercarriage life. Use of Robustus cuts operating costs by up to 30% according to Berco.

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
