Highefficiencyandreliability
·World-class variable displacement piston pump and proportional priority pressure compensating (PPPC)valves with a load sensor hydraulic system specifically designed for motor grader applications,ensuring continuous matching of hydraulic flow and pressure to power demands while allowing for ease of multi-function control and reduction of energy loss for optimizing working efficiency.
·The implement pump has been moved to the Power take-off (PTO) port of transmission and the pump drive shaft under the cab has been removed,decreased working noise,less points for daily maintenance and easy to own.
·The standard blade floatfunctionallows the blade to lowerwithout hydraulic pressure for increased versatility,providing protection for the machine and pavement during snow removal,while reducing the difficulty of work and operator intensity and effectively improving construction efficiency.
·Class-leading circle drive torque delivers higher material spreading and blading capability with superior working efficiency.
·Versatile configurations can meet various customer needs,including options like handle throttle,Drawbar Circle Moldboard (DCM) grease tank,level gauge,rear camera,and transmission guard.
Ease of operation
2
·The cab,mounted on the front frame,providesan exceptional view of the blade and front axle evenwhen using articulation,ensuring thesafetyand accuracy of operation.
·Shortthrow levers are efficiently spaced,allowing ease of multi-function control.The short lever stroke coupled with low lever effort,reduces operator fatigue with and enhances overall operation efficiency.
·The PPPC load sensing hydraulic system maintains consistent and precise blade movement, whether extending or retracting the cylinder,regardless of variable engine speed.
·7-hole link bar with electro-hydraulic control allows for ease of operation within the cab,providing excellent blade extension capability.
·Air conditioning is standard,withadditional airvents from the dashboard and leftand right cab columns for improved comfort.The optimization of cab sealing capability further contributes to lower noise and vibration levels.

Robustness and durability
·The A-frame tubular design drawbar provides maximum strength and durability.The flanged box section front frame removes welds from high-stress areas,improving reliabilityand durability. Continuous top and bottom plate construction ensures consistency and strength, further enhancing front frame durability. ·Leveraging Caterpillar's design and experience with the Motor Grader tandemaxle, there's an improved bearing layout and optimized load distribution with a final drive featuring four planetary gears,oil bath tandemaxle,and longer service intervals for lubrication oil changes without the need to fillin grease frequently. ·Inboard lock check valves within the PPPC system prevent inadvertent cylinder movement and potential leaks. ·The hydraulic driven cooling fan comes with a standard 4 3 ^ { \circ } { C } and optional 50℃ cooling package,providing betteradaptability forall kinds of application environments

Ease of maintenance and lower cost
·Newfamily style metal molded hood offersa bold visual impact,and rightand left lateral doors for easy service and maintenance.
·Replaceable drawbar draft ball(bolted-not welded),allowing for easy removal of wear shims to adjust the drawbar,resulting in less service time and cost.
·The axle tandem comes with an external disk service brake,providing superior braking and a shorter brake distance.The SEMWheel Loader-compatible friction plate allows for easy replacement,and high reliability,while the grease-free lubrication design of the rearaxle and tandem,along with the chain adjustment-free design,prolongs the maintenance cycle, contributing to lower cost of ownership.
·Hydraulic hose routing minimizes exposure to damage and provides quick access for service
· One-key operation for convenient machine and fleet management.
·The transmission filling port is raised up to ease oil changing and protect the port from crashes.Additionally,the transmission oil level dipstick has been replaced with a glasses level gauge,making inspection much more convenient.
5
Operational safety
·The disk service brake features dual circuit braking separately for front/rear braking and left/right braking,ensuring high safety standards.
·The dashboard includes a 3-level alarm monitoring system.
·A three-point contact handrail is provided for easy access and regular inspection and maintenance.
Typical applications such as ground leveling and trenching,slope scraping,bulldozing, snow removal, loosening,distribution,mixing and land reclamation,etc.It is an important equipment in the construction of mine construction, road construction,water conservancy construction and farmland turning and leveling.
