Cat 345D provides more power, fuel economy
Caterpillar’s 345D L hydraulic excavator is a direct replacement for the 345C L. Engine horsepower has been increased by 10 percent, yet the 345D L uses about the same amount of fuel in tough digging, high duty cycle applications. To conserve fuel during light-duty work, the hydraulic and engine control system has been redesigned to include a new power management feature. The operator now has the flexibility to select from alternative engine and hydraulic power settings without sacrificing breakout force or lift capacity. The alternative power options are accessible through the new D-Series monitor in the cab.
The 345D L is equipped with a 380-horsepower (283-kW) Cat C13 engine with ACERT technology. The engine delivers 10 percent more power than the previous model, meets EPA Tier III emissions regulations and offers outstanding performance, reliability and life. Hydraulic flow has been increased by two percent. The main implement pump has been redesigned, and an electric regeneration circuit has been added to boost hydraulic efficiency and reliability. With its higher horsepower engine and more efficient hydraulic system, the new excavator outperforms its predecessor, but it does not sacrifice fuel efficiency. In production applications, the 345D L moves more material per unit of fuel burned. In less intensive applications, alternative power options can reduce fuel consumption by as much as 10 percent while delivering productivity levels comparable to the C-Series model. The 345D L has three undercarriage arrangements to match varying application and transportation requirements: fixed gauge, variable gauge and wide variable gauge. Each option provides excellent stability and long life. Track links have been redesigned to extend service life, and a new carrier roller design improves reliability. The cab is spacious, quiet and comfortable with good ventilation, ergonomic controls and an easy-to-read monitor that displays information in 27 languages to accommodate a diverse workforce. For extra comfort and productivity, a high-back, heated, air-suspension seat is now standard. An optional rear-view camera and Work Area Vision System (WAVS) enhance visibility, productivity and job site safety.
