TATA HITACHI TG14 MOTOR GRADERS

Technical Description

The Tata Hitachi TG14 Motor Grader is a robust construction machine designed for efficient earthmoving and grading tasks. It features a powerful turbocharged 6 A 5.9-C engine with a displacement of 358.9 cubic inches, delivering a maximum power output of 140 hp (104 kW) at optimal RPM. The grader measures 27.9 feet in overall length with a 12.1-foot blade base width, an 8.2-foot width over tires, and a wheelbase of 20.5 feet, offering stability and precise maneuverability. Its front axle provides 2 feet of ground clearance, 19 degrees of total oscillation, and a 48-degree wheel lean for enhanced adaptability on uneven terrain. The hydraulic system uses a fully hydraulic load-sensing gear pump with a closed-center COMPCHECK control valve, capable of a 52.9 gallons per minute pump flow and operating at a relief valve pressure of 2755.8 psi, ensuring responsive blade and steering control. The machine holds 76.7 gallons of fuel and has a total operating weight of roughly 30,953 pounds, distributed as 10,825 pounds on the front axle and 20,128 pounds on the rear axle. The transmission is a ZF ERGOPOWER type with automatic gear shift, featuring six forward and three reverse gears, enabling a maximum forward speed of 24.9 mph and a reverse speed of 17.9 mph. The steering system supports a 24-foot turning radius, optimizing operation in confined spaces. Tire size is 13x24 (12PR), suitable for diverse site conditions. This combination of power, hydraulic efficiency, and control systems makes the TG14 ideal for demanding grading applications.
