Advantages of SEM grader,

  1. High Productivity. Load sensing hydraulic system. It provides consistent and precise blade movement.
  2. High Reliability. A-frame designed drawbar. It provides strength in all blade positions.
  3. Comfort. World Class industry control layout with low lever efforts. It reduces the operator fatigue.

SEM Tandem Axle for motor grader,

  • 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.

SEM motor grader 919 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

Blade Float,

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

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.

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.

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.

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.

Cat ® Product LinkTM,

  • 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.

Large Cab,

  • SEM motor grader 919 with 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.
