Rokbak RA30 excels at German gravel pit
New 28-tonne payload hauler proves ideal addition to hard-working overburden removal fleet
REQUIRING a robust and reliable articulated hauler to remove overburden for 10 hours a day, five days a week, earthworks specialists Erdbau Schrader say they have found the perfect solution with a Rokbak RA30.
Each day, Erdbau Schrader remove around 6,000 tonnes of gravel from a pit near the town of Calbe, in Saxony-Anhalt, Germany. Navigating the site’s tough terrain, up and down steep inclines to unload around 2km away, the RA30 is the latest addition to Erdbau Schrader’s fleet.
‘We chose Rokbak because of their reliability and the price-performance ratio, as well as the hauler’s ability to cope with our long, heavy off-road operations,’ said Ines Schrader, managing director of Erdbau Schrader. ‘We also wanted to ensure that our experienced operators would be able to work with maximum comfort.’
Founded in 2011, Erdbau Schrader already owned four Terex Trucks TA300s – which they bought before Terex Trucks rebranded to Rokbak in September last year. In July this year, the company added the RA30 to its fleet, purchasing the machine from Rokbak dealers Klarmann-Lembach.
‘The Rokbak RA30 is a strong, reliable, and high-performing machine – which is exactly what Erdbau Schrader needed,’ explained Klarmann-Lembach salesman Thomas Keil, who recently visited the Calbe site with Rokbak to see the RA30 in action. ‘Our confidence in the Rokbak brand and the haulers is such that when we were approached, we could assure our customer that the RA30 was the ideal addition to their fleet.’
With its ability to transport a payload of up to 28 tonnes with a heaped capacity of 17.5mᶟ, the RA30 has a maximum engine power of 276kW (370hp) and maximum torque of 1,880Nm at 1,400 rev/min, allowing it to tackle steep inclines with ease.
Routine maintenance is as quick and easy, keeping service time and costs to a minimum. Moreover, factory-approved parts are backed by a two-year/6,000-hour warranty – one of the most comprehensive guarantees in the industry.
Operational comfort is also at the forefront of the RA30 design, with the spacious, ROPS/FOPS-compliant, pressurized cab with heating, ventilation, and air-conditioning (HVAC) helping to keep the operator comfortable and focused.
‘Our operators say they have found the RA30 to be extremely reliable and easily adapted to our heavy, difficult working conditions,’ said Uwe Schrader, who oversees machine usage at Erdbau Schrader. ‘The notable construction of the front axle, with true independent front suspension, offers a very high level of operator comfort across a comprehensive 10-hour working day, which is further elevated by the fully automatic eight-speed transmission.’
The RA30’s EP320 transmission comes with eight forward and four reverse gears and features a top speed of up to 55km/h (34mph), high overall gear ratio spread, equal ratio steps between gears, and optimized gear shifting with partial load shifts. All of this adds up to lower fuel consumption with smoother gear shifting and thereby higher levels of operator comfort as well as faster cycle times and reduced carbon emissions.
Overall, the entire drivetrain helps the hauler deliver class-leading rimpull for superior performance and productivity. It also ensures the machine offers excellent navigation and fast haul cycles. Moreover, the RA30’s long-life transmission fluid increases the length of time between oil maintenance intervals to 4,000 hours, further helping customers achieve increased productivity and uptime, as well as lower cost per tonne.
‘The RA30’s transmission strikes the perfect balance between efficient power, effective gearing, and weight distribution, allowing the hauler to move more loads quicker,’ concluded Thomas Schmitt, Rokbak’s customer support manager for Europe. ‘The RA30 is simple to operate, easy to maintain, and delivers low total cost of ownership with fuel-efficient performance and high productivity – so it’s no wonder the Erdbau Schrader team are so happy with it.’
