BRAKES
SERVICE: All hydraulic brake system control. Transmission mounted pressure compensating piston pump provides hydraulic pressure for brakes and steering. Independent circuits front and rear. Each circuit incorporates a nitrogen/hydraulic accumulator which stores energy to provide instant braking response.
PARKING Rear brakes: applied by spring loaded opposing piston on disc pack, hydraulically released.
RETARDATION–Modulated lever control of rear disc brakes or hydraulic retarder in transmission. 670 kW
(900 hp) continuous retardation.
SECONDARY: Park push button solenoid control applies service and parking brakes. Automatically applies when engine is switched off. Parking brake applies when system pressure fails below a predetermined level.
Front Brakes Dry Disc
Disc diameter. 710 mm
Pad area, total 1394cm2
Rear Brakes TEREX oil cooled, multiple disc, completely sealed from dirt and water.
Braking Surface, total. 47151 cm2
STEERING
Independent hydrostatic steering with closed-centre steering valve, accumulator and pressure compensating piston pump.
Accumulator provides uniform steering regardless of engine speed. In the event of loss of engine power it provides steering of approximately two lock-to-lock turns. A low pressure warning light indicates should the system pressure fall below 83 bar (1200 lbf/in2).
Steering conforms to ISO 5010,SAE J53.
Maximum Tyre Steering Angle 39°
HOIST
Two body hoists mounted inside the frame rails. Hoists are two-stage with power down in the second stage. The body hydraulic system is independent of the steering hydraulic system.

Body Raise Time 16 Seconds
Body Lower Time 14 Seconds
BODY
Longitudinal \'V\' type floor with integral transverse box-section stiffeners. The body is exhaust heated and rests on resilient impact absorption pads. Full time exhaust is optional.
Body floor wear surfaces are high hardness(450 BHN) abrasion resistant steel, of yield strength 1200MPa All other wear surfaces are high hardness (360-440BHN) abrasion resistant steel, of yield strength 1000 MPa
Floor thickness 19 mm
Side thickness 10mm
Front thickness, lower 10mm
Stuck volume . 26 m3
Heaped volume 35 m3
