Komatsu PC290LC-11 Compatible Attachments
The Komatsu PC290LC-11 is a 29-31 ton class hydraulic excavator engineered for exceptional workability and heavy-duty productivity. Powered by a Komatsu SAA6D107E-3 EU Stage IV engine delivering 196 net horsepower, with HydrauMind closed-centre load sensing hydraulics and six programmable working modes, this machine delivers up to 5% lower fuel consumption while maintaining unrivalled performance. The PC290LC-11 offers four arm length choices, two optional hydraulic attachment lines, and ten attachment memory settings for maximum versatility on demanding job sites.
Attachment fitment for the Komatsu PC290LC-11 should be checked against the machine's carrier weight, hydraulic flow from the dual variable displacement pumps, auxiliary circuit setup, pin dimensions, coupler style, mounting bracket, and the type of material being handled or broken. BHE Attachments can help review these details before quoting or installing an attachment.
Komatsu PC290LC-11 Attachment Matches
The attachment categories below are organized for the Komatsu PC290LC-11 carrier class. Final compatibility should be confirmed using the exact machine configuration, hydraulic setup, mounting dimensions, coupler style, and job application.
Hydraulic Breakers for Concrete, Rock & Asphalt
Hydraulic breakers and hammers are a key attachment match for the Komatsu PC290LC-11 when the job requires concrete breaking, rock breaking, asphalt removal, trenching through hard material, or heavy demolition support on large-scale construction and infrastructure projects.
Montabert breaker models previously identified for review with this carrier class include V32, V1800, XL1700, and XL1900. Final selection should be based on the carrier's hydraulic flow, operating pressure, breaker weight, bracket setup, and duty cycle. The dedicated Breaker mode optimizes engine rpm and hydraulic flow, while the Power Max function delivers additional force for the toughest breaking applications.
Heavy-Duty Digging, Trenching, Grading & Cleanup Buckets
Bucket selection for the Komatsu PC290LC-11 should match the heavy-duty work being performed. Digging buckets are commonly used for large-scale excavation and trenching, while grading or cleanup buckets are better suited for ditching, slope work, backfill shaping, and finish grading on major construction sites.
Bucket fitment should be checked by pin diameter, pin spread, stick width, coupler configuration, width, capacity, tooth style, edge type, and material conditions. The PC290LC-11 delivers exceptional digging force with up to 23,100 kg of bucket force at Power Max and a maximum bucket capacity of 2.02 m3. Four arm choices (2.0m, 2.65m, 3.2m, 3.5m) allow tailoring the machine to specific reach and digging depth requirements.
Couplers, Thumbs & Grapples
Couplers, thumbs, and grapples can improve the Komatsu PC290LC-11's usefulness for attachment changes, debris handling, brush handling, demolition cleanup, pipe handling, and sorting material on large commercial and industrial job sites.
These tools should be reviewed for stick geometry, thumb length, coupler type, hydraulic plumbing, bracket style, and the machine's lifting and stability limits. The standard-fit hydraulic quick coupler power circuit and two optional hydraulic lines make it easier than ever to switch working styles. Ten attachment memory settings can be customised for quick recall of preferred flow rates.
Plate Compactors for Trench & Backfill Work
Plate compactors can be reviewed for the Komatsu PC290LC-11 when the work involves trench compaction, utility installation, backfill compaction, road repair, or site preparation on large infrastructure projects where high production compaction is required.
Compactor compatibility should be confirmed by attachment weight, hydraulic flow, pressure range, mounting bracket, hose routing, and the compaction area required for the job. The Attachment Power mode and Attachment Economy mode provide optimised hydraulic flow for powered attachments, with oil flow adjustable directly on the widescreen monitor.
Rippers & Specialty Excavator Tools
Rippers and specialty tools may be considered for the Komatsu PC290LC-11 when the machine is working in compacted soil, frost, hardpan, rocky material, or site preparation conditions where a standard bucket is not the most efficient first tool for heavy-duty pre-excavation work.
Tool selection should be based on material type, breakout needs, carrier size, mounting setup, and whether the tool will be used before bucket excavation or as part of demolition cleanup. The PC290LC-11's massive breakout force, high rigidity boom design with cast boom foot and single piece plates, and Power Max function make it ideal for the toughest ground engagement applications.
Komatsu PC290LC-11 Jobsite Applications
These application notes help connect the Komatsu PC290LC-11 to the attachment type most often used for each kind of work on large construction, infrastructure, quarry, and industrial projects.
Concrete & Rock Breaking
Use a properly sized hydraulic breaker or hammer when the Komatsu PC290LC-11 is assigned to concrete removal, rock breaking, asphalt removal, trench obstruction removal, or heavy demolition prep on large-scale infrastructure and commercial projects.
Excavation & Trenching
Use digging, trenching, or rock buckets when the machine is being used for utility installation, drainage work, foundations, roadwork, and general large-scale excavation where the 6.9 m to 7.2 m digging depth and massive breakout force deliver high production.
Grading & Cleanup
Use grading, cleanup, or ditching buckets when the job requires finish shaping, slope work, ditch cleaning, loose material handling, or surface cleanup on major construction sites, road projects, and landscaping applications.
Material Handling
Use thumbs, grapples, or coupler-supported tools when the Komatsu PC290LC-11 needs to handle debris, brush, pipe, demolition material, or irregular objects on large commercial, industrial, and infrastructure job sites.
Compaction
Use a plate compactor when the machine is supporting trench backfill, utility repair, road repair, or site preparation where controlled high-production compaction is needed on large infrastructure projects.
Hard Ground Preparation
Use a ripper or specialty ground-engagement tool when compacted soil, frost, hardpan, or rocky material needs to be loosened before excavation, leveraging the machine's 23,100 kg bucket breakout force at Power Max and rugged single-piece boom construction.
Attachment Fitment Factors
The Komatsu PC290LC-11 should be matched with attachments using both machine specifications and jobsite requirements. These checks help reduce incorrect fitment, poor performance, and unnecessary attachment wear.
Machine & Mounting Requirements
- Confirm carrier operating weight (29,950 kg to 30,950 kg depending on shoe width) and excavator size class.
- Check pin diameter, pin spread, stick width (2.0m, 2.65m, 3.2m, or 3.5m arm options), and coupler configuration.
- Match the attachment bracket to the Komatsu PC290LC-11 mounting setup.
- Review attachment weight against machine lifting capacity and stability limits.
- For buckets, confirm width, capacity, tooth style, edge type, and application rating.
Hydraulic & Application Requirements
- Confirm hydraulic flow (2 x 239.5 L/min dual pumps) and pressure (380 kg/cm2 implement / 295 kg/cm2 swing) for powered attachments.
- Verify auxiliary hydraulic circuit setup, 2 optional proportional circuits, controls, and hose routing. Select appropriate working mode.
- Select breaker tools based on material, including moil point, chisel, blunt, or specialty tools.
- Match the attachment to the material being worked: concrete, rock, asphalt, soil, brush, or debris.
- Review duty cycle, production needs, operator use, and jobsite conditions before final selection.
