SLEATOR Plant has delivered a Motherwell-manufactured Rokbak RA30 ADT to Loughran Rock Industries, a family-owned quarrying and aggregates business based in County Armagh, Northern Ireland.
Loughran Rock produces between 450,000 and 500,000 tonnes of aggregate every year. Its production supplies local contractors, housing developments and farmers.
“We proposed the RA30 to Loughran Rock for the truck’s agility, dependability, independent suspension for operator comfort and the ability to carry lighter products efficiently,” said Aaron McCaul, a general manager at Sleator Plant.
The RA30 has a 28-tonne maximum payload and a 17.5m3 heaped capacity. The independent suspension and wheel movement is provided by a double wishbone design. This is coupled with 4 x hydraulic dampers/coil over springs.
The truck arrived at the end of 2024 and is predominantly utilised to transport stone, sand, rock-fill and muckshift across the quarry to the main crusher and fill up concrete bins for lorries and block machines. The hauler was customised with body side extensions to maximise load capacity.
“We needed an agile and robust machine to navigate the site’s challenging conditions,” said Colin Loughran, a Loughran Rock quarry manager. “In contrast to rigid trucks, we find the articulated hauler much more efficient on the stockpiles.”
Since arriving, the RA30 has received positive feedback from operator Cathal Devlin, with praise for its visibility, driver comfort and fuel efficiency.
“Visibility is important on any site, especially a big quarry such as this,” Cathal explained. “The rear vision camera and monitor and heated mirrors makes my life a whole lot easier when I’m reversing into tight spots, and when you’re driving around quarries, you need comfort. I’ve been operating for three years now with trucks of all sizes, and the Rokbak truck is definitely the comfiest machine I’ve driven to date.
“I’ve also been impressed by its fuel efficiency. With our previous truck we had to fill it up approximately every two days. With the Rokbak it’s now every three to four.”
