Self-propelled Articulated SEM919 190HP Used Motor Grader

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 .
