| 摘要： | Caterpillar is now offering updated utility compactors for the 2-3tonne class, aimed at customers such as the rental sector. The new CB2.5 GC, CB2.7 GC and CC2.7 CC models benefit from increased productivity and lower owning and operating costs. These replace the earlier CB2.5, CB2.7 and CC2.6 models. Power comes from a Cat 1.7T diesel that meets Tier 4 Final/Stage V emissions requirements and delivers 18.4kW. Of note is that this engine is smaller than the power unit used in the previous models, its higher power density allowing the same output while using less fuel. The engines meet the emissions requirements without the need for an aftertreatment system, reducing maintenance needs and service costs. All three machines are said to benefit from advanced hydraulics and sophisticated power management software to ensure high output. And a new auto idle shutdown reduces fuel use as well as machine hours. An important option is the compaction measurement value (CMV), which displays measured material stiffness to the operator. boosting compaction performance, preventing unnecessary passes and increasing consistency. Meanwhile, the vibration circuit has been optimised to further improve efficiency. |
