SEM921

Advantages

* 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

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
