The CAT 306E2 is a classic 6-ton standard short-tail compact hydraulic excavator of Caterpillar’s E2 series from the United States, a top-selling second-hand model for municipal and landscaping construction worldwide. It features four core competitive advantages: self-developed urea-free Cat C2.4 DI Turbo engine, precise load-sensing hydraulic system, flexible narrow body with side-shift boom and low-center-of-gravity stable undercarriage. It fits all confined-space construction projects including old community renovation, municipal pipeline trenching, landscaping, indoor demolition, farm excavation and small rock crushing. Independent factory hydraulic breaker piping comes as standard for quick installation of breakers, grapples and augers to realize multi-purpose earthmoving and rock-breaking work. The mechanical direct-injection C2.4 engine eliminates urea aftertreatment to simplify maintenance, maintaining stable power output under high-temperature, high-altitude and heavily dusty sites with excellent compatibility with low-grade inferior diesel. Caterpillar operates a comprehensive global network of authorized spare parts warehouses with sufficient wear parts to cut maintenance downtime. Thickened robot-welded booms and stable compact chassis deliver outstanding durability and maneuverability, making it the preferred cost-effective 6-ton mini excavator for overseas landscapers, farmers and small municipal contractors.
