Bell's new generation
By Chris Sleight21 February 2012
The focus of Bell's stand will be its new Mark 7 generation of articulated dump trucks (ADTs). The company says the new 40 ton B40D Mark 7 outperforms rival models by as much as 6% in terms of production, while burning 13% less fuel. A more powerful Stage IIIB engine has improved the truck's power to weight ratio by 6.5% according to the company. This increased power translates to faster cycle times, while the introduction of a wet disc brake has helped reduce drag in the driveline.
The new generation features Stage IIIB engines, and Bell has taken the step of using a selective catalytic reduction (SCR) system to meet the new emission standards. Bell says these new SCR engines from Mercedez Benz are 15% more fuel-efficient than their Stage IIIA predecessors, and the use of this technology is being marketed as the 'Blu@advantage' in reference to the Adblu fluid required for the SCR system.
Bell will also be taking the wraps off a new line of its own-brand lubricants such as engine oil and transmission oil, which have been developed specifically for use with the company's trucks.
