Product Description

Road construction machinery 190HP Motor Grader SEM919 with dozer/ripper
 

Special Tandem Axle

• Leveraging designing and experience on MG tandem axle
• Improved bearing Layout and optimized load distribution with 4 planetary gears final drive
• Less downtime and reduced labor and service cost for maintenance and repairing
• The longer service interval for a 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 the 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 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
• The 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 the drawbar

The motor grader is mainly used for ground leveling, ditching, slope scraping, bulldozing, scarification, snow removal for large areas such as highway, airports, farmlands etc. It is the necessary construction machinery for national defense construction, mine construction, urban and rural road construction and water conservancy construction, farmland improvement and so on.

 

 

1. Energy saving and noise reduction

    Adopt low speed engine transmission line, low fuel consumption and energy saving and environmental protection; The transmission system is equipped with low speed ratio, and the average fuel consumption is reduced by about 8%. Three levels of engine, cab and seat vibration reduction; The cab is supported by six points; Deceleration of engine, cooling fan with large diameter, sound absorption sponge inside the hood, good sealing of the cab reduces noise of the whole machine.

 

2. Strong power

    Shangchai efficient China stage I engine and hydraulic torque converter, the optimal torque converter achieves the best matching of torque converter and engine, reducing the start time, increase the work of torque output at low speed, strong and powerful. The optional herringbone tread tires, the adhesion can be increased by 10% in loosing soil and leveling, further enhance the power output.

3. Rotation with load: 

    Improve the pressure of hydraulic system system, the rotary force of the blade, the high frequency quenching treatment improves the wear resistance and life span, and realize the rotation operation.

 

 

4. Efficient operation: 

    Improves the displacement of hydraulic pump and hydraulic motor, increase the oil cylinder speed by 20%, realizes the industry leading work efficiency, the optimized blade shape can turn and remove the soil quickly and efficiently, and realize optimal load distribution and the minimum material accumulation within the rotary discarea.
