Quarrying
cooled, multi-disc brakes on all six wheels. These are supported by both the engine brake and the transmission retarder, giving the operator superb control and high levels of safety and stability while providing a low cost of operation.
Helping to ensure high levels of operator comfort and productivity, the RA30 has a spacious, ergonomically designed cab with pressurised properties, which ensures operators are comfortable when behind the wheel. Acoustic insulation helps to minimise noise levels inside the cab while a high performance and easily adjusted heating, ventilation, and air conditioning (HVAC) system ensures a stable temperature.
Other features that help to deliver a comfortable work environment include a tilt/telescopic steering wheel, an adaptive air suspension operator’s seat with adjustable armrests, anti-vibration mounts for the engine and cab, and cushioned stops on the steering cylinders.
For safe, easy servicing, the RA30 has ground-level test points, a fully tilting cab and an electronically raised hood that provides safe and easy access to the drivetrain components. A full suite of on-dash diagnostic and machine health check data maximises uptime by reducing intervention time. This includes prognostics for the transmission whereby the operator can immediately check the health of the component, including fluid level, fluid life, filter life, clutch life and more. Again, this reduces intervention time, boosting uptime for owners.
Maximised uptime with Haul Track
The RA30’s engine is linked to Rokbak’s Haul Track telematics system, which allows customers to have complete visibility and control of the hauler. They can access machine GPS location and tracking together with a range of downloadable daily performance reports such as machine hours worked, engine speed, idle time and system fault code alerts. This helps customers to plan maintenance more efficiently and maximise uptime. Measuring productivity also reduces the risk of machinery misuse, prolonging component lifecycles.
