China Sem921 150kw/15.9t Motor Grader Motor Grader 180HP

SEM921 210HP motor grader tires china

* High Productivity: Load sensing hydraulic system provides consistent and precise blade movement

* High Reliability: A-frame designed drawbar provides strength in all blade positions

* Comfort: World Class industry control layout with low lever efforts for reduced operator fatigue

Features:

SEM Tandem Axle

• Leveraging 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

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

® Product Link™

• ® 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
