FP McCann, one of Northern Ireland’s largest quarry operators, has added a second Rokbak RA30 articulated hauler to its fleet that already includes nine Terex Trucks models.“All our haulers work long hours but have proven their worth over the years as tough and dependable, so there was never any real incentive to change brands,” says Chris McCloy, Quarry Manager at FP McCann’s Knockloughrim Quarry where the new Rokbak RA30 is currently working.
“Our mechanics were already very familiar with the Terex Trucks machines, so routine servicing and maintenance has become second nature to them, which helps keep downtime to an absolute minimum.”
Both the RA30 and RA40 feature the latest EU Stage V emissions-compliant engine, allowing fuel efficiency to increase by up to 7% compared to older EU Stage IV engines. The use of ZF’s EP320 fully automatic gearbox, now offers the opportunity to extend oil-maintenance intervals from 1,000 to 4,000 hours with the use of long-life transmission fluid, Rokbak says.
Its 8F/4R gears also offer a higher overall gear ratio spread and smooth gear shifting with partial load shifts resulting in an increase in maximum speed from 50 km/h to 55 km/h. This enables faster cycle times and improved manoeuvrability around the quarry, delivering a lower cost per tonne, the company adds.
