Product Description

SEM CAT Brand 210HP Motor Grader Road Grader with Front Blade and Back Ripper SEM921

SEM Tandem Axle

Leveraging Ca.terpillar 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
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
