CAT 322 Excavator

Caterpillar design and manufacturing techniques assure outstanding service life

Thorough component design and machine validation processes result in unmatched reliability and uptime.

Reinforced front structures help extend machine life in demanding terrain.

Dig and lift from a stable platform created by the 4000 kg (8,820 lb) heavy-duty counterweight and eight-roller undercarriage.

Hydraulic lines protected inside the frame reduce damage risk.

Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.

The latest single-plane cooling package has better air flow, helping to reduce fan speed and save fuel in cooler conditions and lighter applications.

The Turbocharged Cat C3.6 engine and electrohydraulic system work in sync to help you move loads of material without burning excessive fuel.

Eco mode reduces fuel consumption with no loss in lifting or digging forces.

Equipped with electrohydraulic control valve, pump and Engine Control Module (ECM) for better controllability and high fuel efficiency.

The ECM ensures smooth, precise operation in every pass.

Balance power and fuel efficiency using the Positive Flow Control (PVC) electrohydraulic system.

Electronic tandem hydraulic pumps deliver more efficiency with less internal friction losses and superior design.

Boom and stick regeneration circuits reduce fuel consumption while improving cycle times.

Choose from a 1.2 m³ (1.57 yd³) General Duty bucket or a 1.14 m³ (1.49 yd³) General Duty bucket for earthmoving tasks. For quarry applications, select the 1.1 m³ (1.44 yd³) Severe Duty bucket, engineered to handle rock, gravel, and abrasive materials with ease.

Choose between two robust undercarriage options: Medium 4.25 m (13'11") or Long 4.45 m (14'7"), both built to withstand demanding conditions.

Increased swing torque compared to the 320D3 delivers seamless operations while grading, truck loading and trenching.

Traverse the jobsite on the Grease Lubricated Track (GLT) undercarriage. Undercarriage rollers are rebuildable and sealed to prevent dirt and debris from causing internal wear.

Work up to 3000 m (9,840 ft) above sea level without de-rating.

The 322 features a safe, convenient work platform for routine service and maintenance. Anti-skid plating with countersunk bolts reduces slip and trip hazards, while integrated grips on key areas ensure easy access to the platform and operator station.

Shared components simplify maintenance and improve parts availability.

Scheduled Oil Sampling (S·O·SSM) ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of samples for fluid analysis.

Extended and synchronized service intervals save on maintenance costs.

Extended first engine oil change interval (500 hours), and maintenance-free batteries.

The latest cab provides excellent visibility from the operator’s seat. In addition, two standard mirrors help keep you aware of your surroundings.

Optional front windshield guard helps protect the windshield from potential damage caused by flying debris, and other road materials.

Optional rearview camera enhances visibility behind the machine.

Heavy-duty base frame and reinforced “X” car body conform to ISO 15818:2017 lifting and tie-down requirements.

The optional Rollover Protective Structure (ROPS) cab conforms to ISO 12117-2:2008 requirements.

Handrails and hand hold with a step on the undercarriage for easy access to the engine bay area. The handrails conform to ISO 2867:2011 requirements for added safety.

Anti-skid plating with countersunk bolts reduces the potential for slippage and trip hazards.

Start the engine with a push button.

The in-cab high-resolution 203 mm (8 in) touchscreen monitor is easy to use, intuitive, and user-friendly.

Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.
