Caterpillar introduces the 345D L hydraulic excavator, a direct replacement for the 345C L. The new model builds on the strengths of its predecessor, while incorporating new designs that enhance performance and durability.

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 new excavator also has undercarriage improvements, a heavier counterweight for greater stability and lifting performance, a standard heated seat and other new features to make the Cat® 345D L a valuable tool for high-production excavating, loading and underground utilities work.

More power for tougher jobs
The 345D L is equipped with a 380-horsepower (283-kW) Cat C13 engine with ACERTTM Technology. The engine delivers 10 percent more power than the previous model, meets EPA Tier 3 emissions regulations and offers outstanding performance, reliability and life.

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.


Easy operation, convenient service
Like the model it replaces, the 345D L is designed for operators and technicians. 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.

The 345D L retains its predecessor’s serviceable design with easy-access service points and extended maintenance intervals. A new 24-volt power port in the battery compartment accommodates service lights and other electrical equipment. A new electric priming pump is located in the battery compartment, along with the secondary fuel filter which was moved to that area to improve access. Product Link, a Cat system that streamlines asset tracking and maintenance management, comes standard on the 345D L.

Other popular options include High Intensity Discharge (HID) Lights with a time delay function; Machine Security System, which deters theft, vandalism and unauthorized usage; and a second-generation AccuGradeTM system. The new AccuGrade system helps every operator, regardless of skill level, work faster and more accurately. It features an electronic cab avoidance function that prevents damage resulting from contact between the cab, front linkage and bucket. An e-ceiling function protects the machine from interference with overhead obstacles.
