  • Powerful and efficient – Cat® C7.1 ACERT™ engine meets U.S. EPA Tier 4 Final/EU Stage IV emission standards. Emissions technology is transparent – no action required from the operator and no stopping for regeneration.
  • Dedicated swing pump – allows faster and smoother combined movements.
  • Refined hydraulic system – provides increased precision and speed, while preserving fuel consumption.


  • Fuel consumption – reduced up to 10%*, with no impact on your productivity to lower operating costs.
  • Built-in fuel savers – eliminate waste thanks to Auto Engine Speed Control, Engine Idle Shutdown and enhanced Eco Mode.
  • High cooling efficiency – axial fan keeps operating temperatures and costs low.
*Versus previous D MH Series.


  • Blue Angel certified – with low vibrations and sound levels.
  • Options for specific applications – Thicker high impact and impact resistant windshields fulfill respectively the EN356 P8B and P5A standards. A cab pre-filtration package reduces dust entry and air contamination.
  • Great visibility – Large glass areas, LED lights for all working lights and cameras, with both displays split on the same screen.

Ease of Operation

  • Enjoy integrated technologies – They act transparently. Features like the Auto Brake and Axle Lock or Automatic Travel lock remove some of the tasks you had to do.
  • Smart technologies – They help boost your productivity while making operation easier: try the optional SmartBoom™ or Joystick steering.
  • Our cabs are unique –It's a cab just for you where everything can be adjusted, from the seat to the work tools controls assignment on joysticks and pedal.


  • Ground level access – for routine maintenance items like fuel and engine oil filters or fluid taps.
  • Reduced maintenance –Automatic features like electric lift pump and lubrication system along with long greasing intervals.


  • Various configurations – from excavators' flexible offering to MH dedicated solutions. Two MH Boom lengths, straight or drop nose stick and various undercarriages to meet your needs.
  • Various Waste Handling (WH) Packages options – The “fine mesh” package protects the cooling hood from dust and includes an engine air pre-cleaner. The adjustable reversing fan and vibrating grill of the WH package add more protection.
  • Various attachments – to tackle all kinds of jobs, from various grapple types to the 15 kW Cat Generator.

Cat Connect Technology

  • Product Link™ connects owners to their equipment, providing access to machine data such as location, hours, fuel consumption, idle time and events, and diagnostic codes.
