Преимущества и особенности
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.
