Performance where space is limited

The 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:

  • Quick and powerful
  • Impressive fuel efficiency
  • Spacious and comfortable
  • Designed for exceptional stability
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.
Short tail 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.
Rounded cab design with sliding door
  • 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.
Stable platform
  • The compact counterweights provide exceptional lifting capability and stability providing a comfortable, confident operating experience.
Arm quick return valve
  • 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.
