Volvo takes wraps off Tier 4 interim machines
By Chris Sleight11 March 2011
Volvo used last week's Samoter exhibition to unveil its latest loaders, excavators and articulated dump trucks (ADTs), all of which feature low emission Tier 4 interim/Stage IIIB diesel engines. Also new from the company is its B-series backhoe loaders.
In the case of Volvo's new G-series wheeled loaders, the new Tier 4 Interim/Stage IIIB engines accompany a +20% increase in lifting force and +10% improvement in breakout force. The new engines also offer more torque at low revs, which help reduce fuel consumption by up to -15% compared to the F-series machines.
Standard features include Volvo's Optishift driveline system, which improves operator comfort and reduces fuel consumption, and which incorporates its reverse by braking system. A roll over protective structure (ROPS)/ falling object protective structure (FOPS) cab is standard.
The F-series ADTs meanwhile are up to +4% more efficient than the E-series, thanks to their new engines. Features include an articulated steering system and Volvo's automatic traction control system, which prevents the driver from leaving the hauler permanently in all-wheel drive mode, reducing fuel consumption and mechanical wear. A ROPS/FOPS cab is also standard.
The D-Series excavators also include a ROPS cab as standard, while the automatic idling system, combined with advanced hydraulics and the high torque Tier 4 Interim/Stage IIIB engine helps reduce fuel consumption.
Improvements to the B-Series backhoe loader, which is not a Tier 4 Interim/Stage IIIB machine yet include a large cab, offering +15% more space and +30% more glass than its predecessor. High torque, fuel-efficient engines are an important feature, as is the wide range of attachments Volvo is able to offer.
