Product Description
The SEM F series Tier 2 Motor Grader is equipped with an SDEC engine and a PPPC load-sensing hydraulic system for consistent and precise blade movement and reduced fuel consumption. The SEM rear tandem axle, designed and manufactured by Caterpilla, leverages the proven Caterpilla tandem axle design to deliver differentiated reliability and a longer service life, resulting in lower owning & operating costs.
In response to customer suggestions and feedback, the new generation F series Motor Grader has been upgraded to better meet the needs of customers and further improve machine performance. This includes the removal of the transmission shaft, direct connection of the hydraulic pump to the gearbox, and a new molded engine hood with a contemporary aesthetic, providing the machine with a striking and impactful visual design.
With these enhancements, SEM's new F series Motor Grader offers improved competitiveness and solutions to support the success of our dealers and customers.
Operate in comfort
Standard float function for high efficiency and simple operation.
Caterpilla's classic lever control with a short distance and stroke.
Adjustable console and seat with optimized ergonomics.
Cab with improved airtightness and noise reduction.
Added vents in the new dashboard and cab columns for increased comfort.
Low cost per hour
Less heat and fuel consumption; load-sensing and PPPC hydraulic system offer increased efficiency.
Hydraulic cooling fan, high efficiency in various ambient temperature conditions and enhances cooling effect.
Caterpilla (Qingzhou) in-house tandem axle, final drive units with four planetary gears, oil-bath lubrication, and maintenance-free and adjustment-free chain support a higher carrying capability.
Dismountable drawbar ball joint for easy replacement and maintenance.
Performance you need
Up to 2 times more circle drive torque than the industry standard for increased working efficiency.
PPPC hydraulic system ensures precise, predicable and consistent operational movement regardless of engine speed.
Cab is mounted in the frontal frame to provide enhanced visibility for convenient operations.
7-hole linkbar of Electro Hydraulic pin puller offers excellent extensibility of the moldboard, delivering superior performance.
High efficiency and reliability
World-class variable displacement piston pump and proportional priority pressure compensating (PPPC) valves with a load sensor hydraulic system specifically designed for motor grader applications, ensuring continuous matching of hydraulic flow and pressure to power demands while allowing for ease of multi-function control and reduction of energy loss for optimizing working efficiency.
The implement pump has been moved to the Power take-off (PTO) port of transmission and the pump drive shaft under the cab has been removed, decreased working noise, less points for daily maintenance and easy to own.
The standard blade float function allows the blade to lower without hydraulic pressure for increased versatility, providing protection for the machine and pavement during snow removal, while reducing the difficulty of work and operator intensity and effectively improving construction efficiency.
Class-leading circle drive torque delivers higher material spreading and blading capability with superior working efficiency.
Versatile configurations can meet various customer needs, including options like handle throttle, Drawbar Circle Moldboard (DCM) grease tank, level gauge, rear camera, and transmission guard.
Ease of operation
The cab, mounted on the front frame, provides an exceptional view of the blade and front axle even when using articulation, ensuring the safety and accuracy of operation.
Short throw levers are efficiently spaced, allowing ease of multi-function control. The short lever stroke coupled with low lever effort, reduces operator fatigue with and enhances overall operation efficiency.
The PPPC load sensing hydraulic system maintains consistent and precise blade movement, whether extending or retracting the cylinder, regardless of variable engine speed.
7-hole link bar with electro-hydraulic control allows for ease of operation within the cab, providing excellent blade extension capability.
Air conditioning is standard, with additional air vents from the dashboard and left and right cab columns for improved comfort. The optimization of cab sealing capability further contributes to lower noise and vibration levels.
Robustness and durability
The A-frame tubular design drawbar provides maximum strength and durability. The flanged box section front frame removes welds from high-stress areas, improving reliability and durability. Continuous top and bottom plate construction ensures consistency and strength, further enhancing front frame durability.
Leveraging Caterpilla's design and experience with the Motor Grader tandem axle, there's an improved bearing layout and optimized load distribution with a final drive featuring four planetary gears, oil bath tandem axle, and longer service intervals for lubrication oil changes without the need to fill in grease frequently.
Inboard lock check valves within the PPPC system prevent inadvertent cylinder movement and potential leaks.
The hydraulic driven cooling fan comes with a standard 43ºC and optional 50ºC cooling package, providing better adaptability for all kinds of application environments.
Ease of maintenance and lower cost
New family style metal molded hood offers a bold visual impact, and right and left lateral doors for easy service and maintenance.
Replaceable drawbar draft ball (bolted - not welded), allowing for easy removal of wear shims to adjust the drawbar, resulting in less service time and cost.
The axle tandem comes with an external disk service brake, providing superior braking and a shorter brake distance. The SEM Wheel Loader-compatible friction plate allows for easy replacement, and high reliability, while the grease-free lubrication design of the rear axle and tandem, along with the chain adjustment-free design, prolongs the maintenance cycle, contributing to lower cost of ownership.
Hydraulic hose routing minimizes exposure to damage and provides quick access for service.
One-key operation for convenient machine and fleet management.
The transmission filling port is raised up to ease oil changing and protect the port from crashes. Additionally, the transmission oil level dipstick has been replaced with a glasses level gauge, making inspection much more convenient.
Operational safety
The disk service brake features dual circuit braking separately for front/rear braking and left/right braking, ensuring high safety standards.
The dashboard includes a 3-level alarm monitoring system.
A three-point contact handrail is provided for easy access and regular inspection and maintenance.
