CATERPILLAR 14M MOTOR GRADERS

Technical Description

The Caterpillar 14M Motor Grader is a heavy-duty machine designed for precise earthmoving and grading applications. It is powered by a Cat C11 ACERT VHP 6-cylinder engine delivering a base net power of 259 hp (193 kW) at 1800 rpm, with a maximum power output up to 274 hp (204 kW) and peak torque of 1049 lb-ft. The engine supports high ambient conditions up to 122°F (50°C) and has a derating altitude capability of 13,000 ft, optimizing performance in diverse environments. The grader features a 14-foot wide moldboard with a 16.3-inch arc radius and a maximum depth of cut of 17.3 inches, offering extensive blade tip angles of 40° forward and 5° backward, and a maximum blade position angle of 65°, with circle centershift capacities of 25.5 inches left and 20.5 inches right. Moldboard sideshift extends 29.1 inches left and 31.1 inches right, enabling precise material handling and shoulder reach beyond tires up to 89.7 inches. The circle diameter is 71.8 inches with a blade lift above ground of up to 16.5 inches. The machine is built on a robust frame with a wheelbase of 21.5 feet, overall length of 30.9 feet, and width of approximately 9.2 feet over tires. It employs a direct-drive, power-shift countershaft transmission with 8 forward and 6 reverse gears, enabling top speeds of 31 mph forward and 24.5 mph reverse. The electro-hydraulic load-sensing closed-center hydraulic system operates at 3500 psi with a 74 gpm variable displacement pump, supporting efficient implement control. Braking includes spring-applied, hydraulically released parking brakes and oil-actuated disc service brakes. The cab is ISO certified (ROPS/FOPS) ensuring operator safety and comfort. Fuel capacity is 130 gallons, supporting extended operation. The 14M achieves a maximum operating weight near 66,000 lbs, balancing power and stability for demanding grading tasks. This model integrates advanced joystick controls, electronic throttle, and power management technologies for optimized productivity and operator efficiency.
