CAT 870G MOTOR GRADERS

Technical Description

The 2018 CAT 870G Motor Grader is a heavy-duty construction machine designed for precise grading and earthmoving tasks. While specific Caterpillar 870G specs are limited in the provided data, similar high-performance motor graders from competitors like the John Deere 870G offer a useful benchmark. The John Deere 870G, a comparable model, features a 9.0L PowerTech PSS engine delivering up to 209 kW (280 hp) with 1430 Nm peak torque and a net torque rise of 53%, facilitating powerful blade pulling capability exceeding 15,500 kg (34,173 lb). It provides eight forward and reverse speeds, allowing versatile operation in varying terrain. The frame articulation reaches ±22°, with a circle rotation of 360°, and a blade base length of approximately 2530 mm (8 ft 4 in) for broad grading coverage. Operating weight hovers around 20,700 kg (45,668 lb), balancing stability with maneuverability. Controls vary by model but often include advanced, ergonomic operator stations with fingertip-actuated armrest controls or joystick options, optimizing precision and reducing operator fatigue. The premium circle design offers increased torque and speed with low maintenance demands. Integrated automation features on comparable models include Auto-Shift and grade control systems to enhance productivity and accuracy. This class of motor graders is equipped with hydraulic service brakes and designed for all-around visibility to enhance safety and operational efficiency. The CAT 870G aligns with this segment’s standards, providing robust power, reliable hydraulics, and durable construction suitable for road building and heavy site grading operations.
