SEM 190HP Road Motor Grader SEM919 with Front Blade Rear Ripper Attachment
The hydraulic system of the SEM919 190HP motor grader uses an internationally renowned brand variable piston pump PPPC control valve, which distributes power on demand, reducing energy loss and heat generation in the hydraulic system. The hydraulic pump is moved to the rear hood, eliminating the drive shaft and directly connected to the gearbox, which has high transmission efficiency, reduces vehicle operating noise, and improves vehicle performance. The rear axle and balance box bearings are designed without grease lubrication, and the chain is designed without adjustment, which extends the maintenance cycle and saves time, money, and effort.
SEM Tandem Axle
- Leveraging Caterpilar 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
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
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
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
