Product Description

China Famous Brand Hydraulic Motor Grader SEM919 Grader Machine with Rippers

Product Description

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.

SEM Tandem Axle

• Leveraging Cdesigning 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 hydraulicpressure 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.

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 Link^TM

• 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.
