VOLVO G740B MOTOR GRADERS

Technical Description

The Volvo G740B Motor Grader is a heavy-duty construction machine optimized for precise grading and earthmoving tasks. It features a turbocharged 6-cylinder D10BGAE2 engine with a displacement of 586 cubic inches, delivering a maximum power output of 243 hp (181 kW) at 2200 rpm and peak torque of 846 lb-ft at 1100 rpm. The machine offers a powershift transmission with 8 forward and 4 reverse gears, enabling a top forward speed of 27.2 mph (44 kph) and reverse speed of 19.5 mph (31 kph). The grader’s moldboard measures 12 feet in width and 29 inches in height, with a thickness of 1 inch, supporting a maximum cut depth of 32 inches. Blade forces include a down pressure of 19,711 lbs and a pull force of 22,089 lbs. The circle diameter is 66.3 inches, capable of full 360-degree rotation, with blade tip angles of 44 degrees front and 6.5 degrees rear. Lateral blade shifts reach approximately 26.5–30.5 inches left or right, with maximum reach outside tires near 79 inches. The chassis dimension includes a 20.5 ft wheelbase, 30.3 ft overall length, and 8.4 ft width over tires, with a cab height of 10.2 ft. The front axle provides 2.1 ft ground clearance with 16 degrees oscillation and 18 degrees wheel lean for uneven terrain. Hydraulic systems operate at 75.1 gpm with load sensing pumps and 2700 psi relief pressure. Fuel capacity is 120 gallons, hydraulic fluid capacity 35.4 gallons, and the system runs on 24 volts with 75 amps alternator output. Operating weight totals approximately 37,126 lbs, distributed across front and rear axles. The steering articulation angle is 22 degrees. Tires size 14.00 x 24, G-2 type. This robust grading machine is suitable for demanding civil construction and roadwork projects.
