CATERPILLAR 140K MOTOR GRADERS

The Caterpillar 140K is a medium-duty motor grader powered by a Cat C7 ACERT engine producing 128 kW (171 hp) at 2,000 rpm with maximum torque of 996 N·m. This six-cylinder engine features a 7.2-liter displacement and 46% torque rise, delivering variable net power ranging from 128-143 kW (171-191 hp). The grader features a PowerShift countershaft transmission with eight forward speeds ranging from 4.1 km/h to 47.3 km/h and reverse capabilities. The moldboard spans 3.7 meters wide with an aggressive blade design optimized for efficient material movement and a throat clearance of 120 mm. The blade achieves a maximum depth of cut of 735 mm with a 40-degree forward tip range and 5-degree backward range. Articulation angle reaches 20 degrees left/right with maximum shoulder reach outside tires of 1,978 mm (right) and 1,896 mm (left). The machine operates at a gross vehicle weight of 17,271 kg in typical configuration with 12,335 kg on the rear axle and 4,936 kg on the front axle. The circular moldboard has an outer diameter of 1,530 mm with circle centershift capabilities of 752 mm left and 728 mm right. Front axle features 18-degree wheel lean and 32-degree total oscillation per side. The grader includes load-sensing hydraulic circuits, optional AutoShift transmission for automated shifting, and a fuel tank capacity of 305 liters. High ambient capability reaches 50°C with derating altitude at 3,048 meters, making it suitable for demanding applications in varied terrains and climates.
