Lining area-rear axle: 4323 cm 2( 670 in 2)
Total Lining Area: 7782 cm 2( 1206 in 2)

Emergency:Warning light in cab indicates when air pressure drops below 550Kpa(80ibf/in2).Front and rear brakes automatically actuates if system air pressure falls to 310Kpa(45ibf/in2)
Air Compressor Capacity: 533L /min( 18.7ft3 /min)
Total Satety Brake Air Reservoir Capacity: 81L ( 4950in 3)
PARKING:Serbice brakes act as parking brakes and mechanical lock-up when applied by manual control valve on instrument panel. Brake conform to ISO3450,SAE J 1473 OCT90.

Steering

Independent hydrostatic steering with closed-center 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 provide emergency steering of approximately two lock-to-lock turns.
A low pressure warning light indicates ahould the system pressure fall below 8274Kpa(1200ibf/in2)
Maximum Steering Angle:4 2 ·
Steering conforms to ISO5010,SAE J53

Hoist

Two body hoists mounted inside the frame rails.Hoist are two –stage with power down in the second stage.The body hydraulic system is independent of the steering hydraulic system.
System Pressure:13.8Mpa(2000ibf/in2)
Boday Hydraulic pump Flow Rate @ 2100rpm 210L /min(55.5US gal/min)Body Raise Time:14 seconds
Lower Time :9 seconds

Body

Longitudinal “V” shape floor with integral tranvers box –section stiffeners.The strengthened and anti-impacting large –section crossed side plates.The body is exhaust heated and rests on removable resilient inpact absorption pads.
The floor plate is high hardness abrasion resistant steel of high yield strength.Cabguard ROPS SAE J 104C Feb 86 and ISO3471.

Serviceability

A wide ,roomy,two man , cab provides comfort operation and convenient training and maintenance.Air filters , hydraulic tank and its filters are acessible from a wide serbice platform on the right side of the cab.Engine oil and fuel filters are easily reached from ground level.
The transmission is installed in frame independently of engine and rear axle enabling servicing or removeal with minimum disturbance to other components.
Rear axle servicing is straightforward as differential, planetaries or axle shafts may be removed without jacking up the unit.Suspension units front or rear are replaceable with minimum of unit downtime.
