Made to work in your tough, heavy-duty applications
BENEFITS AND FEATURES
Robotic Welding Up to 95% of the structural welds on a Cat Excavator are completed by robots. Robotic welds achieve over three times the penetration of manual welds.
Carbody Design and Track Roller Frames X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units which deliver exceptional strength and service life.
Rollers and Idlers Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life to keep the machine in the field longer.
Standard Undercarriage The standard undercarriage is well suited for machine applications requiring frequent repositioning, restricted working space or uneven rocky terrain.
Long Undercarriage The long undercarriage (L) maximizes stability and lift capacity. This long, wide and sturdy undercarriage offers a very stable work platform.
Tracks The 326D2/D2 L track links are assembled and sealed with grease to decrease internal bushing wear, reduce travel noise and extend service life lowering operating costs.
Counterweights The 4.8 mt (5.2 t) standard weight makes a better choice for heavy lifting with long undercarriage. Counterweights are bolted directly to the main frame for extra rigidity.

Do more jobs with one machine
BENEFITS AND FEATURES
Each Cat work tool attachment is designed to optimize the versatility and performance of your machine. An extensive range of buckets, compactors, grapples, multi-processors, rippers, crushers, pulverizers, hammers, and shears are available for your 326D2/D2 L. Contact your local Cat dealer for more information on the attachments available in your region.
Buckets Cat buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine to ensure optimal performance and fuel efficiency.
General Duty Buckets (GD) These buckets are designed for digging in low-impact, moderately abrasive materials such as dirt, loam, gravel, and clay.
Heavy Duty Buckets (HD) HD buckets are a good starting point when application conditions vary, especially when conditions include mixed dirt, clay, sand, and gravel.
Severe Duty Buckets (SD) These buckets are best suited to highly abrasive applications such as shot rock, sand stone, and granite.
Extreme Duty Buckets (XD) These buckets are for very high abrasion conditions including high quartzite granite. Example: Digging conditions where tip life is less than or equal to 200 hours with Extra Duty tips.
Couplers Quick couplers allow one person to change work tools in seconds for maximum performance and flexibility on a job site. One machine can move rapidly from task to task, and a fleet of similarly equipped machines can share a common work tool inventory.
Center-Lock™ Pin Grabber Coupler Center-Lock is the pin grabber style 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 E Series hammers bring together customer expectations of performance, quality, and serviceability along with Caterpillar manufacturing and logistics experience. E Series hammers are quiet, and noise suppression is valuable in urban and restricted work areas.
Pin On Rippers, Rip and Load Package 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.
Grapples Cat grapples replace the bucket on Cat excavators, converting them to the ideal machine for handling loose material, sorting trash, and demolition site cleanup. An array of styles and sizes are available to match excavators to the task at hand.
Multi-Processors 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 cutting tasks such as cutting steel rebar and tanks.
Shear Cat shears are designed for Cat machines - taking full advantage of the hydraulic flows and pressures to enhance productivity without compromising safety or causing premature wear of the shear and carrier.
Pulverizer The excavator mounted mechanical pulverizer is a cost-effective tool for recycling demolished concrete debris. The bucket cylinder on the excavator powers the mechanical pulverizer. This eliminates the need for a dedicated cylinder and associated hydraulics and additional installation cost.
Vibratory Plate Compactor Compactors enhance the versatility of your excavator and makes compacting faster, more efficient, and cost-effective. Cat compactors are the superior choice for any job site’s compaction tasks.
Crusher The hydraulic concrete crusher has taken modern demolition technology a step further. It is well suited for concrete demolition in residential areas. The hydraulic concrete crusher combines several concrete demolition operations in one piece of equipment:
- breaking out concrete from fixed structures
- pulverizing concrete
- cutting reinforcement rods and small steel profiles
