    •     
  • 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.
