The CAT 312GC is a new-generation 12-ton compact hydraulic excavator of Caterpillar GC series and a widely popular second-hand machine for municipal and landscaping projects worldwide. It features four core strengths: reliable self-developed Cat C3.6 urea-free engine, energy-saving electronically controlled load-sensing hydraulic system, flexible narrow body undercarriage and simplified maintenance design to cut overall operating costs. It fits all confined construction works including residential renovation, municipal pipeline trenching, landscaping, farm digging and small rock crushing. Factory hydraulic breaker piping comes as standard for quick installation of breakers, grapples and augers to realize multi-purpose operation. The genuine C3.6 engine runs stably on low-quality diesel under high-temperature, high-altitude and dusty working conditions with no urea required for Tier3 versions, and passive regeneration for Tier4 models without extra maintenance. Supported by Caterpillar’s global complete spare parts network to reduce maintenance expenses by up to 20%, its compact narrow body fits fully in 20GP container without disassembly, making it the top cost-effective 12-ton excavator for overseas municipal contractors and landscaping rental companies.
