| 摘要： | The 352,374 and 395 are offered for markets with higher emissions requirements, such as Europe, North America, Japan, South Korea, Australia and New Zealand. Meanwhile, the firm is also offering the new 345 GC, 374 and 395 for the Africa, Middle East and Eurasian markets with lower emissions requirements. The heavy construction- and quarrying-suited Cat 352 hydraulic excavator is a 50tonne class model with variable gauge undercarriage said to offer contractors up to 45% more operating efficiency, up to 10% more fuel efficiency, and up to 15% in reduced maintenance costs compared to the model it replaces, the 352F. Powered by a Cat C13 317kW engine, the Cat 352 has a new long-reach configuration reaching out to 19.6m and capable of digging down to 13.04m - suiting it to steep slope work. Standard waterproof technology also provides precision excavation down to 4.5m; the optional submarine solution allows working down to 20m. A heavy-duty high-wide undercarriage and extra counterweight provide a stable platform for long-reach digging. The variable gauge undercarriage enables easier transport between jobsites when retracted and adds stability when extended. The next-generation Cat 345 GC 40tonne class excavator is designed to deliver a balance of performance, reliability, and low-cost operation. The Cat C9.3B 258kW engine-powered excavator can increase fuel efficiency by up to 25% and lower operating costs by up to 30% compared to the 349D2. The new machine also incorporates new safety technology. |
