The CAT 307E2 is a classic 7-ton standard tail compact hydraulic excavator of Caterpillar E2 series from the United States, a widely popular second-hand model for landscaping and municipal construction worldwide. It features four core strengths: reliable self-developed Cat C2.6 DI Turbo engine, high-definition load-sensing hydraulic system, narrow body with side-shift boom and low-center-of-gravity stable undercarriage. It perfectly fits confined-space projects including residential renovation, municipal pipeline trenching, landscaping, farm digging and small rock crushing. Dual-way factory hydraulic breaker piping comes as standard for quick installation of breakers, grapples and augers to realize multi-purpose construction. The mechanical direct-injection C2.6 engine requires no urea aftertreatment for Tier3 versions, simplifying maintenance greatly. It maintains stable power output under high-temperature, high-altitude and dusty working conditions with excellent compatibility with low-grade inferior diesel. Supported by Caterpillar’s global complete spare parts network to cut maintenance downtime, its compact size fits fully in 20GP container without disassembly, making it the top cost-effective 7-ton mini excavator for overseas landscapers, farmers and small municipal contractors.
