Introduction
The Volvo G946B motor grader is a robust and versatile piece of construction machinery designed for precision grading and road maintenance tasks. Manufactured between 2011 and 2014, this model is part of Volvo's G900B series, which was introduced to offer enhanced performance and efficiency in the grading industry.
Development and Production
The G900B series, including the G946B, was developed to meet the growing demands for high-performance motor graders. Volvo aimed to provide machines that offered superior blade down pressure, optimal weight distribution, and advanced transmission systems. The G946B, with its powerful engine and advanced features, quickly gained popularity among contractors and operators seeking reliable equipment for various grading applications.
Engine Specifications
The G946B is equipped with a turbocharged and aftercooled 6-cylinder engine, model D8HGAE4, delivering a net power of 146 horsepower (hp) in gears 1 and 2. This engine provides a displacement of 476 cubic inches (7.8 liters) and a torque output of 730.2 lb-ft. The engine's design ensures efficient fuel consumption and low emissions, adhering to environmental standards of its time.
Hydraulic System and Blade Control
One of the standout features of the G946B is its hydraulic system, which includes a 55-gallon-per-minute (gpm) pump flow. This system powers the machine's blade, allowing for precise control and adjustments. The moldboard, with a width of 12.1 feet (3.66 meters), is designed for optimal cutting and grading performance.
The circle blade, a critical component for maneuverability, offers a 360-degree rotation capability. This feature enables the operator to make precise adjustments without repositioning the entire machine, enhancing efficiency and reducing operational time.
Transmission and Drivetrain
The G946B comes with an 11-speed forward and 6-speed reverse transmission system, providing a total of 11 forward gears and 6 reverse gears. This advanced transmission setup allows for smooth shifting and better control over the machine's speed and power delivery. The transmission's design ensures that the grader can handle various terrains and conditions effectively.
Dimensions and Weight
The G946B has an operating weight of approximately 17.2 tons (17,200 kg). Its standard dimensions include a transport length of 9 meters, a transport width of 3 meters, and a transport height of 3.23 meters. The machine is fitted with 17.5-R25 tires, suitable for a variety of surfaces encountered in grading operations.
Operator Comfort and Safety
Volvo has prioritized operator comfort and safety in the design of the G946B. The machine features an enclosed ROPS/FOPS-certified cabin, providing protection against falling objects and rollover incidents. The cabin is equipped with air conditioning, ergonomic controls, and excellent visibility, ensuring that operators can work efficiently and safely for extended periods.
Applications and Performance
The G946B is suitable for a wide range of applications, including road construction, maintenance, and earthmoving projects. Its powerful engine, precise hydraulic system, and advanced transmission make it capable of handling tasks such as fine grading, ditching, and snow removal.
Operators have reported that the G946B's performance is exceptional, with its ability to maintain consistent blade pressure and deliver smooth, even surfaces. The machine's versatility allows it to adapt to various job site conditions, making it a valuable asset for contractors.
Maintenance and Durability
Volvo's commitment to quality ensures that the G946B is built for durability and longevity. Regular maintenance, such as checking hydraulic fluid levels, inspecting the blade for wear, and ensuring the engine is operating efficiently, is essential to keep the machine in optimal condition.
The G946B's design allows for easy access to key components, simplifying maintenance procedures and reducing downtime. Volvo's global network of service centers and parts suppliers ensures that operators can obtain the necessary support and replacement parts when needed.
Conclusion
The Volvo G946B motor grader stands out as a reliable and efficient machine in the grading industry. Its powerful engine, advanced hydraulic system, and operator-friendly features make it a preferred choice for contractors seeking high-performance equipment. With proper maintenance and care, the G946B can deliver exceptional performance and value over its service life.
