Advantages and Features

PERFORMANCE AND PRODUCTIVITY

  • Cat C7.1 engine meets EU Stage IIIA equivalent emission standards.
  • Engine fuel system designed to manage world-wide fuel quality and provide outstanding low fuel consumption during both working and traveling applications.
  • One-Touch Low Idle Control and Automatic Engine Speed Control reduces engine speed if no operation is performed, reducing fuel consumption and sound levels.
  • Three working modes: Power mode, Eco Mode and Travel mode.
  • Constant Power Strategy, providing a quick response to changing loads, while delivering the same amount of power.
  • Choice of various booms and sticks provides the right balance of reach and digging forces for all applications.
  • Dedicated Swing Pump allows faster and smoother combined movements when using the implements while swinging.

EXPAND YOUR CAPABILITIES

  • Multiple configurations meet all your applications needs, with a choice of booms, sticks, blade and/or stabilizer undercarriages.
  • Highly mobile, the M320D2 can travel up to 37 km/h.
  • Standard one-way high pressure hydraulics allow customers to install attachments like hammers without adding other lines.
  • Ten hydraulic pump flow and pressure settings can be preset within the monitor allowing quicker and easier attachment (optional).
