Product Description
SEM921 Motor Grader 210hp Grader
Product Description(Bulldozer)
SEM Tandem Axle
-
Longer service interval for lubrication oil change.
-
Leading in class manufacturing and quality control level, mandatory performance testing before delivering to MG assembly line.
- 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.
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 LinkTM
- 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.
Product Advantage
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.
