BUILT TO PERFORM

  • Cat C7.1 engine meets EU Stage IIIA, U.S. EPA Tier 3equivalent emission standards and meets China Nonroad III 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. The Automatic Engine Speed Control reduces engine speed if no operation is performed, reducing fuel consumption and sound levels.
  • 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 M322D2 can travel up to 25 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 changes.
  • A lifting eye into the bucket linkage, the heavy lift mode and the overload warning signal allow operators to safely lift heavy loads.
  • Wide range of Cat attachments to handle any job at hand.

OPERATOR COMFORT AND SAFETY

  • ROPS cab structure and Operator Protective Structure (top and front guards) are available.
  • Ergonomically designed cab with controls kept to a minimum, conveniently located and easy to operate.
  • The optional air-suspension seat, with automatic weight adjustment and heated cushions enhance comfort and productivity.
  • Safety is enhanced by the all-round visibility provided by large glass areas and skylight and the standard rear-mounted camera image displayed on the full color monitor.
  • Low sound levels, as a result of the variable fan speed and remote cooling system enabling the machine to be used in noise sensitive areas like urban areas.

LOWER MAINTENANCE COSTS

  • 500 hours fuel filter replacement (reduced to 250 hours if fuel quality is sub-standard) allows reduced maintenance cost.
  • All daily maintenance points are accessible from ground level.
  • Clean design, with colored and numbered electrical wires, protected by thick braiding for ease of service.
  • Greasing points are centralized and kept to a minimum.
  • Cat XT™-6 ES hoses are resistant and durable, which reduce the risk of leaks that can reduce the performance of the machine.
  • Rigidity and long life with effective transmission protection and heavy duty axle.
  • Standard heavy duty batteries for improved cold start capability

INTEGRATED CAT TECHNOLOGIES

  • Cat technology solutions increase production and minimize operating costs. Link technologies wirelessly connect you to your job site, providing machine location, hours, fuel usage, idle timeand event codes.
