Caterpillar® has introduced the 345D L hydraulic excavator, replacing the 345C L.
The 345D L engine delivers 10 percent more power on about the same amount of fuel and meets EPA Tier 3 emissions regulations. Hydraulic flow has been increased by 2 percent. The main implement pump has been redesigned, and an electric regeneration circuit has been added to boost hydraulic efficiency and reliability.
The new excavator also has undercarriage improvements, a heavier counterweight for greater stability and lifting performance, a standard heated seat, and other new features for high-production excavating, loading and underground utilities work.
