SEM921 Motor Grader

SEM Tandem Axle

• Leveraging Caterpillar 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

Cat ® Product Link™

• 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
