SANY OFF-HIGHWAY TRUCK

Frame

Box structure with variable-section provides resistance to bending and torsion.

Mild steel used throughout bumper, front and rear longitudinal beams, torque tubes, rear mounting rack provides flexibility and resistance to impact loads. Low alloy cast-steel components are used in the high-stress areas for a higher strength and greater life frame.

Engine

Model.........................................................................................Cummins M11-C350

Type............................................................4 Cycle Turbocharged / Charge air cooled Gross power @ 2,100 rpm................................................................261 kW(350 hp) Net power @ 2,100 rpm .................................................................. 238 kW(319 hp) Power ratings based on SAE J1995 June 90. Engine emission meets USA EPA/CARB MOH 40 CFR 89 and proposed EU non-road mobile machinery directive.

Maximum Torque @ 1,300 rpm.................................................1,559N.m(1,150 lb.ft)

Number of Cylinders/Configuration.............................................................. 6, in line Bore Stroke.......................................................... Φ125 x 147 mm (4.92 x 5.79 in) Displacement.......................................................................................10.8L (661 in³)

Transmission

Allison 4430ORS electronic automatic control transmission especially for off- highway truck. Forth generation commercial electronic controls MY09. Integrated hydraulic torque converter and hydraulic retarder. Five speeds forward, one reverse. Automatic lock-up in all speed ranges. Transmission is provided with hydraulic retarder and hoist restrict shift protect function.

Drive Axle

Heavy duty axle with full floating axle shafts, single reduction spiral bevel gear differential and planetary reduction at each wheel. High strength cast steel welded construction.

Ratios: Differential...............................................................................................3.2:1

Planetary.............................................................................................................4.5:1

Total Reduction.................................................................................................14.4:1

Suspension

Front: Macpherson type independent suspension with variable rate, nitrogen/oil cylinder for effective absorption of road shocks.

Rear: Variable rate nitrogen/oil cylinders with A-frame linkage and lateral stabilizer bar.

Maximum strut stroke: Front............................................................250 mm (9.84 in) Rear.............................................................160 mm (6.30 in)

Tyres

Brakes

Service brake - Leading and trailing shoe, cam, drum brake. Independent front and rear dual circuits, pneumatic mechanism. When truck runs on wet surface, dry & wet valve can reduce front wheel brake pressure by half and the braking control performance is improved.

Front axle braking surface...............................................................3,459cm2(536in2) Rear axle braking surface................................................................4,324cm2(670in2) Total surface of brake shoe pad....................................................7,783cm2(1,206in2) Parking brake –Finger operated switch on instrument panel applies parking brake and vehicle is locked by mechanism.

Retarding brake – Two levers control hydraulic retarder in transmission.

Emergency brake – When system pressure falls to 550kPa(80 lbf/in2), cab warning light will illuminates. When system pressure falls to 310kPa(45 lbf/in2), front and rear brakes will be automatically applied.

Independent hydraulic steering with closed-center steering valve, pressure com-

pensating piston pump and accumulator.

Accumulator provides uniform steering regardless of engine speed. In the event of loss of engine power, it provides emergency power to system for steering. A low pressure indicator light warns of system pressure below 115bar (1,660 lbf/in2). Minimum turning diameter......................…….............................................14,800mm

Hoist

Independently hydraulic system.Two hoist cylinders are mounted between the frame rails to keep stable of body while raises the body.

System Relief Pressure.............................................................180bar (2,610 lbf/in2) Body Hydraulic Pump Flow Rate @ 2,100 rpm................210L/min (55.5 USgal/min) Body raise time.............................................................................……............14 sec Body lower time..........................................................................……...............  9 sec

Body

The body is dual “V” structure which gives good load retention and a low centre of gravity. The bottom plates are constructed from high tensile strength import abrasion-resistant steel. Thickness:Floor.......................................…...................................... 16 mm (0.63 in)

Side................................................................................... 8 mm (0.31 in) Front.......................................................….........................8 mm (0.31 in)

Volumes: Struck (SAE)...................................................................16.5 m3 (21.5 yd3) Heaped 2:1(SAE)...............................................................21.5 m3 (28 yd3)

Cab

Large area of windscreen gives operator an all-around visibility. Acoustic lining

                                                                                                              material provides quiet operator space. Suspension seat reduces vibration
