Caterpillar launches new equipment and a major deal with Rio Tinto

Caterpillar Inc. launched two major pieces of mining equipment this autumn.

The Caterpillar 980H wheel loader features key changes to improve productivity, operator comfort and serviceability compared with the model it replaces, the 980G series II. A new Cat engine with ACERT technology, the addition of electronic clutch pressure control, and a new cooling system work together to boost productivity. Increased cab insulation reduces sound experienced by the operator, and an improved ladder design eases access and egress.

The engine is tier III-compliant and provides advanced electronic control, precision fuel delivery and refined air management for outstanding engine performance. The six-cylinder engine has 15.2-l displacement and produces 237 kW (net) in the 980H.

The company also launched the 345C L hydraulic excavator. The new C-series excavator features the Cat C13 engine with ACERT technology for powerful, reliable performance and reduced emissions. The C13 boosts engine horsepower 7.5% compared with the 345B series II, which the 345C L replaces. The combination of increased horsepower, higher hydraulic system pressure and greater breakout force enhances machine productivity.

The 345C L weighs about 44,300 kg in the fixed gauge configuration and 45,800 kg in the wider, more robust variable gauge configuration. Standard bucket capacity is 1.90 m3. The Cat C13 engine meets EPA tier III and EU stage IIIa exhaust emissions standards while maintaining reliability, durability and performance.

In early January Rio Tinto plc sign- ed a five-year contract establishing Caterpillar as the primary supplier of ancillary mining equipment for its worldwide mining operations. The agreement covers certain classes of haul trucks and support equipment. The contract focuses on competitive costs to operate and maintain equipment over its life cycle, a strategy that drives excellence in equipment design and deployment. It also provides for continuous technology and service improvements. Rio Tinto expects to spend more than US$1 billion on heavy equipment manufactured by Caterpillar and other suppliers over the next five years.
