Build Number: 06D

Work up to 4500 m (14,764 ft) above sea level without derating.
Powerful digging force and strong swing torque enable the use of large buckets up to 3.2 m3 (4.2 yd3) for class-leading productivity.
Powerful swing torque easily handles changes in momentum, uneven terrain, and consistent high-impact connections, helping operators make their work swift and precise.
Did you know baffle plates help increase an excavator’s strength-to-weight ratio? That is why Caterpillar incorporates the plates in high-stress areas like the boom, stick, and frame. Reinforcing the machine without adding significantly more weight also helps provide years of reliable performance, even in the harshest environments.
The cylinder rods are reinforced with additional wear rings to help reduce oil leaks. The car body has thick baffle plates for a long service life. The thick track link has large bolt joints to help maintain bolt retention. Track rollers have a large shaft diameter to help prevent bending and oil leaks while increasing the 350’s loading capacity, which means more reliable production for you.
Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
The center track guiding guard helps align the excavator track when traveling and working on slopes.
The sloped track frame prevents mud and debris accumulation, helping reduce the risk of track damage.
Auxiliary hydraulic options allow you to use a wide range of Cat® attachments.
Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
Match the excavator to the job with three operating modes: Power, Smart, and ECO.
Smart mode automatically adjusts power for the highest fuel efficiency – less power for tasks such as swinging and more power for digging.
Enhanced heavy lift mode increases system pressure to help you easily pick and place heavy material.
Auto warm-up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
Don’t let the temperature stop you from working. This excavator has a high-ambient capability of 52° C (125° F) and a standard cold start capability of –18° C (-0.4° F).
The engine meets U.S. EPA Tier 4 Final, EU Stage V, Korea Stage V and Japan 2014 emission standards with an aftertreatment system that requires no operator input or downtime.

The latest operator oriented User Interface (UI) has been designed to maximize uptime by allowing operators to easily reorder work tool lists and quickly create new work tool combinations.
