Features At A Glance

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.
