Steering
g Angle to Either Side: 45° | Lock to Lock Turns, Steering Wheel: 4 | Type: 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 springs.
Rear Suspension
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
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
