2024 Komatsu Excavators PC238USLC-11
Performance where space is limitedThe power and stability you need in a compact and easy-to-transport package. Designed to excel in underground utility or general construction in urban environments, this short tail swing excavator is at home in tight spaces.
Features may include:
Short implement swing radius- Get greater clearance when space is limited with a higher boom raise angle than our standard excavator that reduces the minimum front implement swing radius.
- Get more done in confined areas with the short tail swing radius that allows the machine to work in more spaces than our conventional excavator.
- High maneuverability is achieved through the purpose-built cabs that swings within the same radius as the counterweight. The sliding cab door allows operators to easily enter and exit when space is limited.
- The compact counterweights provide exceptional lifting capability and stability providing a comfortable, confident operating experience.
- Help improve efficiency with the quick return valve that directs additional oil through a second line directly back to the tank when the arm is extended, helping to reduce back pressure and fuel consumption.
