Applications: – Finish blading , heavy blading ,road maintenance, side slope work, high bank slope work, ditch cutting /building, ditch cleaning ,ripping /scarifying , snow removal/snow plowing
Advantages of SEM919:
* High Productivity: Load sensing hydraulic system provides consistent and precise blade movement
* High Reliability: A-frame designed drawbar provides SEM919 motor grader strength in all blade positions
* Comfort: World Class industry control layout with low lever efforts for reduced operator fatigue
Remarkable Features:
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
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
-Standard blade float function allows SEM919 motor grader"s 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 SEM919 motor grader 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 SEM919 motor grader power consumption and hydraulic system heat, improving fuel efficiency
-Load-sensing hydraulic system provides SEM919 motor grader 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 SEM919 motor grader 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 SEM919 motor grader 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
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
