Find Attachments for Your Caterpillar Excavator

Caterpillar excavators are used across utility construction, demolition, earthmoving, trenching, quarry work, grading, material handling and large-scale excavation. Choosing the correct attachment requires matching the tool to both the carrier and the work being performed.

Hydraulic breakers for Caterpillar excavators

Hydraulic Breakers

Break concrete, asphalt, rock and compacted material with a hydraulic breaker properly sized for the Caterpillar carrier class and hydraulic output.

Confirm operating weight, hydraulic flow, pressure, back pressure, mounting bracket and intended duty cycle before selection.

Buckets for Caterpillar excavators

Excavator Buckets

Choose digging, trenching, grading, cleanup, rock, skeleton or severe-duty buckets according to soil conditions and the required finished result.

Bucket fitment should be checked by pin dimensions, coupler type, width, capacity, tooth style and material density.

Quick couplers for Caterpillar excavators

Couplers and Quick Hitches

Quick couplers can reduce attachment change time and allow one Caterpillar excavator to perform several tasks during the same project.

Confirm the excavator model, stick configuration, pin dimensions, safety requirements and attachment interface.

Thumbs and grapples for Caterpillar excavators

Thumbs and Grapples

Improve material handling for brush, pipe, logs, demolition debris, rocks, scrap and irregular material.

Selection depends on stick geometry, attachment weight, hydraulic plumbing, lifting capacity and coupler setup.

Plate compactors for Caterpillar excavators

Plate Compactors

Compact trench backfill, road base and utility installation material without moving a separate compaction machine into the work area.

Match the compactor to carrier weight, hydraulic flow, operating pressure, mounting bracket and compaction area.

Rippers and specialty tools for Caterpillar excavators

Rippers and Specialty Tools

Rippers and specialty excavator tools can improve production in frost, hardpan, compacted soil and rocky material.

Tool size and construction should match the machine class, ground conditions and intended working depth.

Caterpillar Attachment Fitment Information

A machine model provides the starting point for attachment selection, but it does not guarantee that every attachment listed for that carrier class will fit every machine configuration.

Machine Information

  • Complete Caterpillar model number
  • Machine serial number or product identification number
  • Approximate operating weight
  • Boom and stick configuration
  • Stick length and attachment linkage
  • Current coupler or pin-on arrangement

Attachment Information

  • Required attachment type and application
  • Hydraulic flow and pressure requirements
  • Pin diameter, pin spread and stick width
  • Mounting bracket or coupler interface
  • Attachment operating weight
  • Auxiliary hydraulic circuit setup

Why Attachment Sizing Matters

An attachment that is too large or too heavy can reduce stability, place unnecessary stress on the boom and stick and prevent the excavator from operating efficiently.

Hydraulic attachments must operate within the machine's available oil flow, pressure and back-pressure limits. Proper sizing helps protect the carrier while improving productivity and service life.

Common Applications

  • Concrete and asphalt demolition
  • Rock breaking and quarry work
  • Utility excavation and trenching
  • Foundation and site excavation
  • Road and infrastructure construction
  • Grading and ditch maintenance
  • Brush, debris and material handling
  • Trench and backfill compaction
