Caterpillar 16M3 Grader Geared for Mining

The Cat 16M3 motor grader has a Cat C13 ACERT engine with the Cat Optimized Variable-Horsepower system that allows net power ratings from 290-348 horsepower. The engine can be configured in three different ways to meet emissions standards: Tier 4-Final, Tier 3, and Tier 2.

The 71,454-pound grader has a 16-foot moldboard geared toward maintaining mine haul roads for 150-ton and smallet trucks, the company says.

ECO mode, standard on Tier 2 and Tier 4 engines, optimizes engine speed to 1,900 rpm when possible for fuel savings up to 5 percent, the company says. An additional engine control system feature provides consistent power to the ground by continually adjusting the engine to compensate for power losses to the cooling fan.

The “OK-to-Start” system automatically checks the engine coolant, engine oil, and hydraulic oil levels when the key is turned to the on position. The system also monitors these levels and the trans-axle oil level during operation, and it alerts the operator if levels drop too low.

The direct-drive, power-shift transmission has eight forward and six reverse gears, and has the Cat Advanced Productivity Electronic Control Strategy (APECS) system that is designed to smooth gear changes and promote productivity.

The full-color touch-screen display, with an intuitive menu structure, allows the operator to monitor machine performance, set parameters to suit operating situations, and access service information for initial troubleshooting.

The grader has a standard rearview camera system and a seat belt indicator, which alerts the operator that the belt is not fastened and records the incident as a fault code.

In the engine enclosure, clearance above the valve cover allows injectors, compression brakes, and valves to be serviced without removing any major components. The modular design of the rear axle allows removing the final drives in-chassis.

A new modular cooling package facilitates removal and installation of components in the cooling system, providing an estimated time saving of 20 percent compared with the 16M, according to Cat.
