Using Economy mode and automatic engine speed control minimize fuel use and increase engine efficiency.
New tandem hydraulic pumps provide more hydraulic power with less internal friction to increase overall efficiency.
With 20% less refill oil volume than the 320D2 and reduced frequency of refills increases uptime and reduce costs.
Move more, faster with a larger Cat® 1.20 m3 (1.57 yd3) severe-duty bucket
Use 15 percent less fuel in Economy mode with no loss in lifting or digging forces
A two-stage filtering system with integrated water separator protects the engine from particles larger than four microns when fuel quality is less than ideal
Critical machine information is always visible in the new high resolution 178 mm (7 in) monitor
Anti-skid plating with countersunk bolts reduces the potential for slippage and trip hazards
Lower your maintenance costs by up to 5% with 20% less refill oil volume than the 320D2 and maintenance free batteries

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..
E Series hammers bring together customer expectations for performance, quality, and serviceability along with Caterpillar manufacturing expertise. They are also quiet – a significant benefit in urban and noise-restricted work areas.
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:
