China 210HP Ripper Hydraulic Front Blade Rear Ripper Motor Road Grader SEM921 for Sale
Chinese Tandem Axle
- Leveraging designing and experience on 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 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 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 versatilityBlade 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
