CATERPILLAR 16H MOTOR GRADERS

Technical Description

The Caterpillar 16H Motor Grader is a robust, high-performance machine designed for demanding road construction and land grading applications. It features a 6-cylinder Caterpillar 3406 turbocharged and aftercooled diesel engine, delivering up to 285 hp (213 kW) at 2000 rpm, with peak torque of 1143 lb-ft. The grader is equipped with an 8-speed direct drive, power shift, planetary transmission for smooth operation in both forward and reverse. The moldboard is 16 ft (4.877 m) wide, 31 in (787 mm) high, and 1 in (25 mm) thick, fabricated from wear-resistant, high-carbon steel, with a maximum depth of cut of 18.5 in (470 mm). The circle system allows for a blade tip angle of 40° forward and 5° rear, a maximum lift of 16.5 in (419 mm), and a reach of 91 in (2311 mm) outside the tires on both sides. The machine has a total operating weight of 54,560 lb (24,748 kg), with a maximum operational weight of 69,648 lb (31,590 kg). Hydraulic system pressure is rated at 3500 psi, utilizing an axial piston pump. The articulation steering system provides a 20° articulation angle and a 27 ft (8.2 m) turning radius, while the front axle offers 32° total oscillation and 18° wheel lean. The 16H has an overall length of 32.8 ft (9.99 m), a width of 10.1 ft (3.08 m), and a height to the top of the Isomount cab of 11.6 ft (3.54 m). Fluid capacities include 130 gal (492 L) fuel, 12.3 gal (46.6 L) cooling system, and 30.1 gal (114 L) rear differential/final drive.
