Suspension
Front :NHL manufactured king pin strut type independent front wheel suspension by self-contained ,variable rate, nitrogen/oil cylinder. Rear :NHL manufactured variable rate nitrogen/oil cylinder with A-frame linkage and lateral stabilizer bar.
Maximum Strut Stroke:Front: 225mm
Rear: 160mm
Maximum Rear Oscillation:±8°
Tyres
Standard:front & rear 18.00-25(28PR) E3 Tubeless Rim:13.00/25
Note:Under certain job condition the t-km/h(ton-mile/h)capacity of standard or optional tyres may be exceeded .We recommend that tyre manufacturers be consulted for optimum type selection.
Brakes
SERVICE:dual shoe,internal expanding,mechanically actuated by air pressure.Independednt front and rear circle systems actuated by single treadle valve with auxiliary manual control.Operator controlled dry/wet road valve reduces front brake pressure 50% for improved control in slippery conditions
Front Linings:Diameter x width:508x 152 mm
Area-front axle: 3459 cm2
Rear Linings: Diameter x width::508x 190 mm
Area-rear axle: 4323 cm2
Total Lining Area: 7782 cm2
Emergency-Warning light in cab indicates when air pressure drops below 550Kpa.Front and rear brakes automatically actuates if system air pressure falls to 310Kpa.
PARKING-Service brakes act as parking brakes when applied by manual control valve on instrument panel
Steering
Full hydraulic power steering by two double-acting when applied cylinders. Pressure is supplied to a load sensing and priority steering valves by an engine driven gear pump. The system provides uniform steering regardless of engine speed.
Maximum Tire Steering Angle:40 Degrees
Hoist
Two body hoists mounted inside the frame rails.Hoist are two –stage with power down in the second stage.Hydraulic system is powered by the gear pump.
Body Raise Time:13 seconds
Body Lower Time:9 seconds
Body
Longitudinal “V” shape floor plate with integral transverse box –section stiffeners the body resilient inpact absorption pads.
Body wear surfaces are high strength and high hardness abrasion resistant steel.
