Technical Description

The 2006 Caterpillar 12H VHP Plus Motor Grader is a heavy-duty construction machine powered by a Cat C-9 ETA VHP Plus engine producing 185 hp with 1,137 lb-ft of maximum torque at 2,000 rpm. This six-cylinder, turbocharged diesel engine displaces 427.8 cubic inches and features an electronically controlled fuel injection system for optimized efficiency and emissions control. The grader utilizes a direct-drive, power-shift transmission with eight forward speeds and six reverse speeds, enabling maximum forward speeds up to 27.4 mph and reverse speeds to 21.6 mph. The 14-foot moldboard blade offers extensive positioning capabilities with a maximum depth of cut of 28.9 inches and maximum lift of 18.9 inches above ground. The blade features a DH-2 steel cutting edge and can achieve blade tip angles of 40 degrees forward and 5 degrees backward, with full 360-degree circle rotation and 90-degree maximum blade position angles. Weighing 33,294 pounds at base gross vehicle weight rating and up to 41,603 pounds at maximum, the machine operates on 18.4-26 inch tires with an articulation angle of 20 degrees and turning radius of 24.25 feet. The closed-center, electro-hydraulic load-sensing system delivers 74 gallons per minute at 3,500 psi maximum pressure. Standard equipment includes a 24-volt electrical system with 150-amp alternator, hydraulic blade float control for snow removal, and optional ripping attachments with five shank holders. The grader delivers superior moldboard control and productivity for road construction, maintenance, and snow removal applications.
