SEM 915 motor grader

 

Machine specifications

 

Improved Engine

• 6.5L Shanghai Diesel engine delivering 150HP
• Best-in-class after treament to ensure the particulate matter and NOX emissions are reduced.
• World-class Diesel Particulate Filter (DPF) is deployed to reduce soot from the exhaust.
• Diesel Exhaust Fluid (DEF) is sprayed in the exhaust by an electronically controlled injector.
• Hydraulically driven engine fan reduces the fuel consumption.
• Caterpillar patented cooling system provides ease of service and longer engine life.

 

Control System

7 position link bar with optional 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.

 

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.

 

Transmission

• Industry leading supplier – Hangzhou Advance Gearbox Group Co., Ltd.
• Specifically designed for motor grader application.
• 6F / 3R electronically controlled hydraulically actuated gears.
• Torque converter ensures steady flow of power to the transmission.

 

Blade Float

Optional 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.

 

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.

 

SEM Tandem Axle

• Leveraging Caterpillar design and experience on MG tandem axle.
• Mandatory performance testing before delivering to MG assembly line.
• 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.

 

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.
• Short throw levers are efficiently spaced, allowing ease of multi-function control.
• Short lever travel (40mm) with low effort reduces operator fatigue, providing exceptional comfort.

 

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.

 

SEM Tandem Axle

• Leveraging Caterpillar design and experience on MG tandem axle.
• Mandatory performance testing before delivering to MG assembly line.
• 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
