Product Description
SEM 919/921 Motor Grader
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 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
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
FFront Fram
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
