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
