Experience the power and stability you require in a compact and easily transportable package. Specifically engineered to excel in underground utility or general construction projects in urban environments, this short tail swing excavator thrives in tight spaces.

  • Quick and powerful performance.
  • Impressive fuel efficiency.
  • Spacious and comfortable operator cabin.
  • Designed for exceptional stability.

Product Features and benefits:

Short Implement Swing Radius: Increase clearance in confined spaces with a higher boom raise angle, reducing the minimum front implement swing radius compared to our standard excavator.

Short Tail Swing Radius: Enhance productivity in limited areas with the short tail swing radius, allowing the machine to operate in spaces beyond the reach of conventional excavators.

Rounded Cab Design with Sliding Door: Achieve high maneuverability with purpose-built cabs that swing within the counterweight radius. The sliding cab door facilitates easy entry and exit in tight spaces.

Stable Platform: Compact counterweights deliver exceptional lifting capability and stability, ensuring a comfortable and confident operating experience.

Arm Quick Return Valve: Boost efficiency with the quick return valve, directing additional oil back to the tank when the arm is extended. This reduces back pressure and fuel consumption.

Efficient Hydraulic System: The closed-center loading system (CLSS) ensures quick response to operator demands, improving fuel efficiency. Pilot proportional control (PPC) hydraulics and optional proportional joysticks provide exceptional control.
