Komatsu PC238USLC-11 Compatible Attachments
The Komatsu PC238USLC-11 is a 24.6-ton class tight-tail hydraulic excavator, engineered to deliver conventional performance in a compact-radius body. Powered by the Komatsu SAA6D107E-3 Tier 4 Final engine delivering 123 kW (165 HP) net horsepower at 2,000 RPM, this machine combines heavy counterweight mass with a short tail swing radius of just 1,810 mm for superior lifting capacity in confined work environments.
With a maximum digging depth of 6,620 mm and digging reach of 9,875 mm, the PC238USLC-11 excels at road work, underground utilities, demolition support, and site preparation where space is restricted. Attachment fitment should be checked against the machine's carrier weight, hydraulic flow and pressure, pin dimensions, boom and arm configuration, and the material being handled. BHE Attachments can help review these details before quoting or installing an attachment.
Komatsu PC238USLC-11 Attachment Matches
The attachment categories below are organized for the Komatsu PC238USLC-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 PC238USLC-11 when the job requires concrete breaking, rock breaking, asphalt removal, trenching through hard material, or demolition support in road work and confined commercial spaces.
Montabert breaker models previously identified for review with this carrier class include the M900, V32, XL1700, XL1900, and V1800. Final selection should be based on the carrier's hydraulic flow of 475 L/min with closed-center load sensing system, 37.3 MPa relief valve setting, breaker weight, bracket setup, and duty cycle. The machine features a dedicated B mode (Breaker mode) that optimizes engine rpm and hydraulic flow for breaker operation.
Digging, Trenching, Grading & Cleanup Buckets
Bucket selection for the Komatsu PC238USLC-11 should match the work being performed. Digging buckets are commonly used for excavation and trenching in utility and roadwork projects, while grading or cleanup buckets are better suited for ditching, slope work, backfill shaping, and finish grading.
Bucket fitment should be checked by pin diameter, pin spread, stick width, coupler configuration, width, capacity, tooth style, edge type, and material conditions. The PC238USLC-11 offers a 2,925 mm arm with bucket capacities ranging from 0.50 m3 to 1.20 m3 depending on tooth style and application rating. Available bucket types include TL, HP, HPS, and HPX for material weights up to 3,500 lb/yd3.
Couplers, Thumbs & Grapples
Couplers, thumbs, and grapples can improve the Komatsu PC238USLC-11's versatility for attachment changes, debris handling, brush handling, demolition cleanup, pipe handling, and sorting material on job sites where road work and underground utilities demand frequent tool changes.
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 PC238USLC-11 features a 6,720 kg heavy counterweight providing exceptional lifting capacity comparable to conventional excavators in the same size class. Optional JRB couplers including Smart-Loc and Versa-Loc are available for quick attachment changes.
Plate Compactors for Trench & Backfill Work
Plate compactors can be reviewed for the Komatsu PC238USLC-11 when the work involves trench compaction, utility installation, backfill compaction, road repair, or site preparation in urban and highway work zones.
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 PC238USLC-11 delivers 475 L/min maximum hydraulic flow with a closed-center load sensing system and pressure compensated valves for smooth powered attachment operation. Six working modes including ATT/P and ATT/E optimize attachment performance.
Rippers & Specialty Excavator Tools
Rippers and specialty tools may be considered for the Komatsu PC238USLC-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.
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 PC238USLC-11 delivers 149 kN bucket digging force with Power Max function and 108 kN arm crowd force for tough ground conditions. The one-touch Power Max function provides 8.5 seconds of increased digging force when needed.
Komatsu PC238USLC-11 Jobsite Applications
These application notes help connect the Komatsu PC238USLC-11 to the attachment type most often used for each kind of work.
Concrete & Rock Breaking
Use a properly sized hydraulic breaker or hammer when the Komatsu PC238USLC-11 is assigned to concrete removal, rock breaking, asphalt removal, trench obstruction removal, or demolition prep in road work and confined commercial spaces.
Excavation & Trenching
Use digging, trenching, or rock buckets when the machine is being used for utility installation, drainage work, road construction, foundations, and general excavation in tight-access areas.
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 roadwork and utility job sites.
Material Handling
Use thumbs, grapples, or coupler-supported tools when the Komatsu PC238USLC-11 needs to handle debris, brush, pipe, demolition material, or irregular objects in restricted urban and highway work zones.
Compaction
Use a plate compactor when the machine is supporting trench backfill, utility repair, road repair, or site preparation where controlled compaction is needed in limited work areas.
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 in road work or utility settings.
Attachment Fitment Factors
The Komatsu PC238USLC-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 (24,600–25,250 kg depending on shoe configuration) and excavator size class.
- Check pin diameter, pin spread, stick width, and coupler configuration.
- Match the attachment bracket to the Komatsu PC238USLC-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.
- Verify boom and arm configuration (5,700 mm one-piece boom, 2,925 mm arm) and shoe width (600, 700, or 800 mm).
Hydraulic & Application Requirements
- Confirm hydraulic flow (475 L/min maximum) and pressure (37.3 MPa implement circuits) for powered attachments.
- Verify auxiliary hydraulic circuit setup, controls, and hose routing (service valve with one additional actuator available).
- 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.
- Consider working mode selection (P, E, L, B, ATT/P, ATT/E) for optimal attachment performance.
