KOMATSU PC350-7 CRAWLER EXCAVATORS

Technical Description

The Komatsu PC350-7 is a heavy-duty hydraulic excavator engineered for demanding excavation and material handling applications. Powered by a turbocharged Komatsu SAA6D114E diesel engine, this machine delivers 241.4 horsepower at 1900 rpm, generating 180 kilowatts of output with exceptional hydraulic power and improved fuel efficiency. The excavator weighs 71,209 pounds in operating configuration and features a robust bucket capacity of 1.9 cubic yards, making it suitable for large-scale earthmoving operations. The PC350-7 demonstrates impressive working range capabilities, with a maximum digging height of 33.5 feet, maximum reach along ground of 35.9 feet, and maximum digging depth of 24.3 feet. Its minimum swing radius is 14.2 feet, enabling efficient operation in confined spaces. The machine incorporates advanced productivity features including four selectable working modes—Active, Economy, Lifting, and Breaker modes—that optimize engine speed, pump speed, and system pressure for specific applications. When Power Max function is engaged, bucket digging force and arm crowd force increase by 7 percent compared to previous models. Built for durability and stability, the excavator features a reinforced heavy-duty boom, arm, and large counterweight system. Its undercarriage consists of 45 shoes per side with 23.7-inch dimensions and dual carrier rollers per side, generating only 9.6 psi ground pressure for minimal surface disturbance. The machine achieves maximum travel speeds of 3.5 mph and delivers exceptional drawbar pull of 59,349.6 pounds, providing superior steering and slope-climbing performance with a 17 percent increase over previous generations.
