How to Select Attachments for Komatsu Excavator Classes

Attachment selection across the PC-Series requires understanding three key variables: the MR factor, the LC factor, and the Dash-generation factor.

The MR (Mini Radius) models — PC18MR through PC55MR — are Komatsu's zero-tail-swing specialists, designed for tight urban environments where rear clearance matters. These machines are typically matched with compact buckets, small breakers, augers and thumbs for utility work, landscaping and residential construction. MR attachments must preserve the machine's compact swing profile — TGEC verifies rear-swing clearance on each MR-attachment combination. Standard mini excavators like the PC60 and PC70 use conventional tail-swing designs with larger mounting dimensions and are commonly preferred in rental fleets and general construction.

The medium PC models — PC110 through PC270 — represent the backbone of Komatsu's construction lineup and support heavy buckets, rippers, demolition grapples and breakers for commercial construction, site development and roadwork. LC variants like the PC210LC and PC270LC feature extended undercarriages for added stability and can carry heavier attachments than standard models of the same hydraulic output. TGEC sizes LC attachments to take advantage of this stability for lift capacity and digging force.

The large PC models — PC300 through PC490 — are used for quarry work, heavy demolition and large-scale construction. These machines have larger pin diameters and heavier mounting dimensions than medium models, requiring attachments built with reinforced structures and wear-resistant materials. LC variants in this class provide additional stability for heavier attachments.

The mining-class machines — PC600 through PC800 — operate in heavy production environments. Attachments for mining-class Komatsu machines use oversized pins, heavy-duty bushings, hardened wear materials and reinforced structures designed for continuous operation in abrasive conditions. TGEC mining-class attachments are built to the carrier's weight and hydraulic specifications, with field-replaceable wear components.

The Dash-generation factor adds another layer. Komatsu's pin sizes, ear spacing and bushing dimensions changed across Dash-5, -6, -7, -8 and -10 series. An attachment built for a PC200-8 will not fit a PC200-6 without modification. TGEC builds every attachment to your specific machine's Dash series and serial number.
