Product Description

SEM Motor Graders SEM921 Road Grader

Advantages of SEM921 Motor Grader:

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

* High Reliability: A-frame designed drawbar provides SEM921 motor grader strength in all blade positions

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

Remarkable Features:

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 SEM921 motor grader's 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 SEM921 motor grader 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 SEM921 motor grader power consumption and hydraulic system heat, improving fuel efficiency

-Load-sensing hydraulic system provides SEM921 motor grader 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 SEM921 motor grader 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 SEM921 motor grader reliability and durability

-Continuous top and bottom plate construction provides SEM921 motor grader 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
