Technical Description

The Volvo G946B motor grader is a heavy-duty construction machine designed for precise earthmoving and grading tasks. It features a turbocharged, aftercooled 6-cylinder D8HGAE4 engine with 476 cubic inches displacement, delivering 146 hp and 730 lb-ft of torque in the first two gears. The grader has an overall length of 30 ft, width of 8.3 ft over the tires, and a wheelbase of 20.5 ft, with a front ground clearance of 2 ft and cab height of 10.5 ft. Its moldboard measures 12.1 ft in width, 25 in height, and 0.9 in thickness, allowed to operate at a max cut depth of 31 in, with blade down pressure reaching 18,651 lbs and a blade pull at maximum weight of 36,760 lbs. The circle mechanism offers 360-degree rotation with tip angles of 45 degrees front and 6 degrees rear, and max circle shifts of about 30 in left and 29.5 in right. The hydraulic system, powered by an axial piston pump at 55 gpm and relief valve pressure of 3000 psi, manages blade controls and other functions. The grader runs on 14:00 x 24 G-2 tires, with a standard operating weight of 38,515 lbs and a maximum operating weight near 48,000 lbs. Its transmission is a fully sequential, direct drive Volvo powershift with 8 forward and 4 reverse gears, reaching max forward speed of 27.3 mph. The front axle provides 2 ft ground clearance with 16 degrees oscillation and 18 degrees wheel lean, while steering articulation is 23 degrees. Operating voltage is 24 volts with hydraulics and cooling systems designed for high efficiency in demanding conditions.
