Komatsu PC170LC-11 Compatible Attachments
The Komatsu PC170LC-11 is a 17.6–19.6-ton class hydraulic excavator, engineered to deliver enhanced power and productivity with two counterweight options for expanded versatility. Powered by the Komatsu SAA4D107E-3 Tier 4 Final engine delivering 90 kW (121 HP) net horsepower at 2,100 RPM, this machine combines new engine and hydraulic control technology for up to 6% improved multifunction performance compared to its predecessor.
With standard and heavy counterweight options (2,750 kg and 3,240 kg respectively), the PC170LC-11 adapts to transport requirements on a 40,000 lb tag trailer or maximizes stability when equipped with a quick coupler and attachments. It excels at utility work, road construction, site development, and general excavation. 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 PC170LC-11 Attachment Matches
The attachment categories below are organized for the Komatsu PC170LC-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 PC170LC-11 when the job requires concrete breaking, rock breaking, asphalt removal, trenching through hard material, or demolition support in road work and commercial construction.
Montabert breaker models previously identified for review with this carrier class include the M900 and XL1300. Final selection should be based on the carrier's hydraulic flow of 298 L/min with HydrauMind 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) providing one-way flow optimized for hydraulic breaker operation.
Digging, Trenching, Grading & Cleanup Buckets
Bucket selection for the Komatsu PC170LC-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 PC170LC-11 offers 2,610 mm and 2,900 mm arm options with bucket capacities ranging from 0.37 m3 to 0.95 m3 depending on tooth style and application rating. Available bucket types include TL, HP, and HPS for material weights up to 3,500 lb/yd3.
Couplers, Thumbs & Grapples
Couplers, thumbs, and grapples can improve the Komatsu PC170LC-11's versatility for attachment changes, debris handling, brush handling, demolition cleanup, pipe handling, and sorting material on job sites where utility work and road construction 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 PC170LC-11 offers standard (2,750 kg) and heavy (3,240 kg) counterweight options to maintain stability when equipped with a quick coupler, bucket, and additional attachments. Optional hydraulic couplers and thumbs are available for quick attachment changes.
Plate Compactors for Trench & Backfill Work
Plate compactors can be reviewed for the Komatsu PC170LC-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 PC170LC-11 delivers 298 L/min maximum hydraulic flow with a HydrauMind closed-center system and pressure compensated valves for smooth powered attachment operation. Six working modes including ATT/P and ATT/E optimize two-way flow attachment performance.
Rippers & Specialty Excavator Tools
Rippers and specialty tools may be considered for the Komatsu PC170LC-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 PC170LC-11 delivers 123 kN bucket digging force with Power Max function and 86.3 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 PC170LC-11 Jobsite Applications
These application notes help connect the Komatsu PC170LC-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 PC170LC-11 is assigned to concrete removal, rock breaking, asphalt removal, trench obstruction removal, or demolition prep in road work and commercial construction.
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.
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 PC170LC-11 needs to handle debris, brush, pipe, demolition material, or irregular objects on construction and utility job sites.
Compaction
Use a plate compactor when the machine is supporting trench backfill, utility repair, road repair, or site preparation where controlled compaction is needed.
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 PC170LC-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 (17,600–19,598 kg depending on counterweight and shoe configuration) and excavator size class.
- Check pin diameter, pin spread, stick width, and coupler configuration.
- Match the attachment bracket to the Komatsu PC170LC-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 (5,150 mm one-piece boom, 2,610 mm or 2,900 mm arm) and shoe width (600, 700, or 800 mm).
- Consider counterweight option (standard 2,750 kg or heavy 3,240 kg) for stability with quick couplers and heavy attachments.
Hydraulic & Application Requirements
- Confirm hydraulic flow (298 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.
