YCRAULIC EXCAVATOR SY235C

Innovative Features of Controller

1. Precise controller customized for SANY.2. Faster computing speed, 66% higher than lastgeneration.

3. Automatic self-diagnosis and recovery system.4. Remote Diagnosis: according to the real-time applica-tions, shown on the centralized diagnosticmonitor, determine the location of the faults that mayoccur remotely.

Advanced computer dynamic control technologyprovides real-time match between engine power andmain pump power.

th a dual-pump, dual-circuit constant power control system, the Isuzu 6BG1 engine power can be

ed more efficiently. This perfect combination produces higher operating efficiency with lower fuel

nsumption by selecting heavy duty mode under high workload, or standard or light duty mode withtomatic engine speed regulation.

Larger Workload

The main pump consists of two plunger-typeumps of serial variable displacement. The

wo pumps are controlled via full-powerariables, meaning that the sum of power ofwo pumps is kept constant. When a singleump is running, this pump can absorb theower of the other idle hydraulic pump tonsure the full use of engine power.

With hydraulic elements provided by world famous companiesand world advanced and mature hydraulic system of electronicpositive flow control, Sany excavators are capable of maintaininghigh operating efficiency on the basis of high system stability andbetter operability.

A quick circuit is added to the arm oil cylinder circuit. When thearm oil cylinder is extended, the oil return circuit is cut off andhydraulic oil flows from the return circuit into the cylinder via acheck valve. The hydraulic oil in arm cylinder rod end does notreturn the tank but goes directly to the cylinder head end. Thearm speed is increased as a result. The fuel consumption is lowunder this condition.

Pressure Loss Reduced with The Use of EfficientHydraulic Components

Improved pump efficiency: A variety of improvements, includingthe improvement of clearances between internal pump parts,minimizes the leakage.

The engine, main pump, main valve and other core components,tailored by the world famous suppliers for Sany, are designed inconsideration of the overall performance of Sany excavator. Thepositive flow hydraulic system and the advanced computerdynamic control technology are used to provide real-time matchbetween engine power and main pump power while effectivelymaximizing the machine performance and significantly reducingthe fuel consumption.

With closed-loop control, the controllerutomatically regulates the power absorbedy hydraulic pump according to the changesf engine load during the operation, keeping

he power of hydraulic pump matching up tohe power of engine at all times. Namely, theontroller sets the power of engine accordingo specific conditions to reduce the workingntensity of engine and ensures a stable andconomic engine application.

The electric control module has the capability of making quickresponse to the change of operating variables in order to

achieve optimum engine performance. It is fully integratedwith sensors of fuel, engine oil, air intake, coolant andexhaust system to conduct the real-time monitoring andauto-adjustment on the system conditions, which can ensurethe engine won't overload when the excavator works with fullload.

Boom

High-strength machine High reinforced swing platform

Track rollers, carrier rollers


Strong structure with higher reliability

Boom, Arm and Bucket Meeting Customer Requirement

Reinforced X- frame modeled withdigital tools, through finite elementanalysis on loading capacityrealizes high-strength structure.

Reinforced plates, welded on thetwo main beam of swingplatform,considerably improve thebending resistance performance.

Track rollers, carrier rollers and idlersuse seal-in lubrication that gives alonger service life. The tri-grousertrack shoe rolled with high-strengthalloy provides favorable contact,stability and durability. The track linkshave additional reinforced ribs toincrease their strength, which canabsorb the shock when the machinetravels on rough surface.

Six Cylinder Diesel EngineExcellent Cooling Effect

Displacement 6.494L

The engine customized for SANY gives high efficiency, low fuel consumption and high

reliability while fully guaranteeing the excavators stability in continuous operation

under severe weather conditions and satisfying customers for requirement of engine

stability.

Six-cylinder engine ensures highreliability and stability of themachine as a whole.

Fan Guard: The radiator fan isenclosed with a protective netcover that prevents objects fromfalling into the fan to damage itsblades.Serially Arranged Coolers: waterradiator, oil radiator, intercoolerand condenser are arranged sideby side; the aluminum radiatorgives better cooling effect.

With the engine power of 128.5kw,SY235C has a displacement up to6.494L, which reduces the engineheat load and gives a longerservice life.

With strengthened boom, arm and bucket, SY235C can better meet the customers require-

ment for heavy duty operation over a long period of time.

Important parts of the boom havebeen fully reinforced. With stron-ger front and rear supporting

plates, the lateral stress is downby 10% during the boom swing.

ArmThe rear support of arm is speciallyreinforced, offering excellenttorsion resistance under the

complex applications.

BucketStandard reinforced bucket withhighly rigid steel sheet, tips andside cutters can serve a longer

period.

The innovative large cab isequipped with an adjustable seatwith suspension. The rigidity ofseat can also be adjusted accord-ing to the operators weight.

The sealed design ensures thatthe air pressure inside the cab ishigher than outside, thus prevent-ing the dust invasion.

The standard large-capacity airconditioner keeps in-cab air freshby purifying fresh air and recircula-tion air. The quick temperaturecontrol ensures a comfortable

temperature in cab all the yearround.

The operator station is supportedwith innovative silicone rubbershock absorber. which hasminimized the shock brought byrough road and engine or hydraulicimpact, considerably increased thestability of cab, and improved thecomfort of operator.

With a high-rigid structure, the newcab uses damping materials thatgive a better noise-absorbing effect.The adoption of properly sealedwindows, noise reduction designand low-noise engine enables themachine to produce a noise as lowas a passenger car.

The control levers and joysticksdesigned and arranged accordingto ergonomic, can be operatedeasily.

Hydraulic Lockout Control

When the hydraulic lockoutcontrol is placed in LOCKposition, all controls areinoperable, which preventsaccidents caused byunintentional operation.

Falling Object Protection Structure

The top plate of cab is punch-formed withthick high-strength steel sheet integratedwith reinforced ribs,which maximizes thesafety of operator.

Rear view mirror ismounted on both sidesof the cab, which canobserve the situationbehind the excavatorwithout looking back.

The engine is housed in excel-lent heat insulation to preventaccidental burns.The radiator fan is enclosedwith a protective net cover thatcan prevent objects from fallinginto the fan to damage itsblades.

The pump chamber and enginechamber are separated with ascreen, which can preventleaked hydraulic oil from splash-ing onto the hot engine.

Env ir o nment - f r iend l y Engine

ISUZU engine customized for Sany isable to precisely control the engine fuelinjection in order to ensure fullcombustion of fuel.

Advanced computer dynamic controltechnology (CDCS) provides real-timematch between engine power and mainpump power, realizing the perfectcombination of power and economy.

Auto Deceleration System

The function of auto deceleration oracceleration reduces fuel consumptionby 5-10%. When an operation has beenstopped for 3 seconds, the engine speeddrops automatically to idle level andmaintains the idling state, thus reducingthe void flows in the hydraulic system,wear of diesel engine, energyconsumption and noise.

Three Stage Air Filtering

Equipped with air pre-cleaner and dual airfiltering elements, the three-stage air cleanerensures supply of sufficient clean air thatcan reduce the wear of cylinders. It is usefulfor harsh working environment that is windyor dusty.
