CATERPILLAR 140M AWD VHP PLUS MOTOR GRADERS

Technical Description

The 2009 Caterpillar 140M AWD VHP Plus Motor Grader is a powerful, versatile machine designed for heavy-duty grading applications. It features a Cat C9 ACERT engine delivering 186 horsepower with Variable Horsepower Plus (VHP Plus) that enhances torque rise by 39%, providing optimal power and fuel efficiency during operation. The engine delivers peak torque of approximately 855 lb-ft at 1,000 rpm and meets Tier 3/Stage IIIA emissions standards, with no derating required up to 10,000 ft altitude. The grader has an operating weight of 51,893 lbs, ensuring excellent traction and stability for demanding tasks. The machine includes a 12-foot moldboard with a 60.2-inch wide circle diameter, providing efficient material manipulation and grading precision. It operates with an 8-speed forward and 6-speed reverse direct drive power-shift countershaft transmission for smooth and responsive control. The AWD system improves traction and stability, particularly on challenging terrain, and delivers additional horsepower to the ground to maximize performance. Hydraulically, the grader is equipped with an electro-hydraulic load-sensing, closed-center system featuring dual pumps for precise implement control. The front and rear axles are designed for durability and flexibility, allowing up to 18 degrees wheel lean and 32 degrees total oscillation for superior maneuverability. The cab offers ergonomic electro-hydraulic joystick controls that significantly reduce operator fatigue by up to 78%. With 7,397 operational hours, this reliable motor grader is engineered for productivity, durability, and comfort, suited for construction, mining, and road maintenance applications requiring consistent performance in varied conditions.
