The turbocharged Cat C3.6 engine works seamlessly with an advanced electrohydraulic system to deliver smooth, precise operation while burning less fuel.
Eco mode helps you save without sacrificing digging or lifting power, while automatic engine speed control cuts fuel use when loads are light. The electronic tandem hydraulic pumps deliver high efficiency with low friction losses.
Smart pump design and regeneration circuits further reduce fuel burn while keeping cycle times fast. The result: low operating costs shift after shift.
Ground-level S·O·SSM ports make fluid sampling quick and convenient, while grouped filters and an electric priming pump help reduce contamination risk. Anti-skid platforms with textured grip surfaces provide secure footing, ensuring confident, stable access during every service routine.
Longer intervals, like 500-hour oil changes, and maintenance-free batteries keep your schedule on track.
An advanced hydraulic oil filter design extends component life, while two-stage fuel filtration and anti-rust tank coatings protect against low-quality fuel.
Sites where excavators work are typically rugged and challenging. That’s why it’s important that the 322 cab helps protect the operator as much as possible from fatigue, stresses, sounds, and temperatures of the job.
Optional guards, alarms, and reinforced structures add extra layers of protection. Paired with LED lighting for round-the-clock jobs, this machine is designed to help every operator go home safe at the end of the day.

Cat buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine to ensure optimal performance and fuel efficiency.
Center-Lock is a pin grabber coupler and features a patent-pending locking system. A highly visible secondary lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool..
Cat® Hammers make short work of your demolition, construction, and quarry needs. Combine the simple, lightweight design of the GC Hammer series with the reliability, durability, and value you expect from Cat products. The result is a low cost per hour solution providing the consistent power and performance you need.
Constructed from high-strength steels and built to last, Cat rippers endure in the toughest conditions. The box-section structure is reinforced for maximum rigidity, transmitting the full machine power to the material being ripped. Rippers feature a replaceable wear tip, and most models also come equipped with a replaceable shank protector.
Cat grapples make Cat excavators the ideal machine for handling loose material, sorting trash, and demolition site cleanup. An array of styles and sizes is available to match excavators to the task at hand.
Multi-processors do the work of many types of demolition tools by use of interchangeable jaw sets. Changing jaws allows a single unit to crush, pulverize, and perform a variety of specialized tasks such as cutting steel rebar and tanks.
Cat shears are designed to take full advantage of the hydraulic flows and pressures produced by Cat excavators – all to enhance productivity without compromising safety or causing premature wear of the shear or carrier.
Mechanical pulverizers are cost-effective tools for recycling demolished concrete debris. The bucket cylinder on the excavator powers the pulverizer, eliminating the need for a dedicated cylinder, associated hydraulics, and additional installation cost.
Cat compactors make job site compaction quick, efficient, and cost effective.
The hydraulic concrete crusher is well suited for demolition in residential areas. The tool combines several demolition operations in one piece of equipment:
