Caterpillar's 990K wheel loader offers more power and increased payload for improved productivity and fuel efficiency. It features a redesigned cab that delivers a sleek operator interface and quiet environment, as well as several features to promote operator and maintenance technician safety and performance. It has a rated payload of 17.5 tons, while the Performance Series Buckets are said to promote quick and full bucket loading. A Cat C27 Acert engine powers the unit and delivers 699 horsepower to increase produc- tion. Fuel saving features include ECO Mode, an engine-idle shut- down system, and engine-idle kickdown/auto-resume mode. Caterpillar | www.cat.com The Doosan DL250TC-5 wheel loader offers improvements in fuel effi- ciency, operator comfort, serviceability, reliability, and remote monitoring with Doosan Telematics. The Tier 4 Final loader is powered by a Doosan DL06 engine and has 172 horsepower. The tool carrier features a parallel lift-arm design that helps keep loads level while the wheel loader is mov- ing. Limited-slip differentials give the machines more traction when exca- vating, grading, or loading trucks. The unit also features an auto-shutdown system to save fuel. Operators can configure the idle time before shutdown from 3 to 60 minutes. Doosan Infracore Construction Equipment | www.doosanequipment.com The Case Construction Equipment 721F wheel loader meets Tier 4 Final emission standards. It is equipped with a selective catalytic reduction (SCR) solution that treats emissions sepa- rately with Diesel Exhaust Fluid (DEF) and does not require the engine to re-circulate exhaust gas. This is said to improve fuel efficiency by up to 20 percent, lower exhaust temperatures, and provide excellent throttle response and simplified maintenance without sacrificing power. It also requires no DPF regeneration or maintenance. Powered by a 6.7-liter engine, it produces 179 net rated horsepower. It is available with tool carrier or extend- ed reach linkage and in specialty configurations.
