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
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
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
