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 forservice

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
