2023 Rokbak RA40 Tier 2
The RA40 is a heavy-duty articulated hauler that makes light work of large scale quarry, mine, and construction jobs. High capacity and high performance – you can trust the RA40 to deliver maximum productivity in the toughest conditions.
Features may include:OPTIMISED FOR EFFICIENCY AND PERFORMANCEThe RA40’s high-performance engine balances controlled power with maximum fuel efficiency.
SAFETY AND CONTROLA modulating transmission retarder is coupled with an efficient exhaust brake and fully enclosed oil-cooled multidisc brakes for total control – even on steep inclines.
FULLY ADAPTABLE DRIVETRAINThe RA40’s adaptable drivetrain maintains traction and speed on the toughest jobsites – for outstanding productivity anywhere.
PLANETARY GEAR TRANSMISSIONSmooth, efficient gear shifting cuts fuel costs and increases operator comfort – even under the most challenging conditions.
MAXIMUM UPTIMEGround level test points, a fully tilting cab and an electronically raised hood make servicing quick and easy.
KEEP TRACK OF YOUR HAULEROur bespoke Haul Track system lets you quickly and easily protect your hauler and maximise its productivity. With live data viewable remotely from your desktop computer or mobile device, you’re always in control.

Steering
Angle to Either Side: 45° | Lock to Lock Turns, Wheel: 4 | Hydrostatic power steering by two doubleacting cushioned steering cylinders with pressure supplied by a variable displacement/ load sensing piston pump. Secondary steering pressure provided by a ground driven pump
Suspension
Front Suspension
Fully independent suspension and wheel movement is provided by a double wishbone design. This is coupled with 4 x hydraulic dampers/coil over spring
Rear Suspension
Each axle is coupled to the frame by three rubber-bushed links with lateral restraint by a transverse link. Pivoting inter-axle balance beams equalise load on each rear axle. Suspension movement is cushioned by rubber/ metal laminated compression units between each axle and underside of balance beam ends. Pivot points on leading and trailing links are rubber-bushed and maintenance-free
Brakes
Brake System Type
Tyres:All hydraulic braking systems with multiplate sealed and oil cooled brake packs at each wheel. Independent circuits for front and rear brake systems | Secondary: Secondary brake control actuates service and parking brakes | Retarder: Exhaust brake and transmission retarder
Parking Brake
Spring-applied, hydraulic-released disc on rear driveline
