Stability and power for tight spaces
Built for working in tight spaces like roadways, bridges or urban areas, this tight tail swing radius excavator is designed for exceptional stability, with responsive quick arm speed and a purpose-built cab for operator comfort.
- Quick and powerful
- Impressive fuel efficiency
- Spacious and comfortable
- Designed for exceptional stability
Features and benefits
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.
Efficient hydraulic system
For quick response to operator demands, the closed-center loading system (CLSS) helps improve fuel efficiency. Pilot proportional control (PPC) hydraulics and optional proportional joysticks provide exceptional control.
