Large Cab

  • High performance dashboard with 3 levels alarming monition system
  • Cab mounted on the front frame provides exceptional view to blade and front axle even during articulation
  • Large cab with 1.9m height and 30% larger space than most competitors, provides exceptional comfort

Cat ® Product Link&trade

  • Cat ® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management.

Control Layout

  • Short throw levers are efficiently spaced, allowing ease of multi-function control
  • Short lever travel (40mm) with low lever effort reduces operator fatigue

Front Frame

  • Flanged box section design removes welds from high stress areas, improving reliability and durability
  • Continuous top and bottom plate construction provides consistency and strength, improving front frame durability
  • Hydraulic hose routing minimizes exposure to damage and provides quick access for service
  • Maintenance-free bushings improve durability and reduce overall service cost

Drawbar

  • A-frame tubular design drawbar provides maximum strength and durability
  • Replaceable drawbar draft ball (bolted – not welded) for less service time and cost
  • Easy removal of wear shims to adjust drawbar

Hydraulic System

  • Proportional Priority Pressure Compensating (PPPC) Valves contain specifically cut spools for motor grader applications, continuously matching of hydraulic flow and pressure to power demands, allowing ease of multi-function control for optimizing working efficiency
  • World-class variable displacement piston pump, efficiently reduces power consumption and hydraulic system heat, improving fuel efficiency
  • Load-sensing hydraulic system provides consistent and precise blade movement, improving finishing performance
  • Inboard lock check valves within PPPC, prevents inadvertent cylinder movement and potential leaks

Blade Float

  • Standard blade float function allows blade to lower without hydraulic pressure for increased versatility
  • Blade float is engaged by pushing the left and right lift cylinder controls all the way forward past the detent
  • Provides protection for machine and pavement during snow removal and snow plowing

Control System

  • 7 position link bar with electric over hydraulic control allows ease of operation from within the cab
  • Optimum blade reach capability, quick DCM re-positioning for greater reach for better working on high bank side slope
  • The link bar is essential for extending reach capability when cutting a bank slope or back slope of a ditch
  • Replaceable bushings reduce service time and cost

SEM Tandem Axle

  • Leveraging Caterpillar designing and experience on MG tandem axle
  • Improved bearing Layout and optimized load distribution with 4 planetary gears final drive
  • Less down time and reduced labor and service cost for maintenance and repairing
  • Longer service interval for lubrication oil change
  • Leading in class manufacturing and quality control level, mandatory　 performance testing before delivering to MG assembly line
