OVERVIEW

BENEFITS

FEATURES AT A GLANCE

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 reduce 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 M320 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).
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

Operator Protective Guards (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.

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 reduces the risk of leaks that can decrease 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 time and event codes.
