The attachments buyers in your market ask for first, sized for the PC118MR-8.
Which coupler is on your machine?
Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.
How to measure your coupler
Not sure which system it is? Three measurements tell us which bracket you need.
- Measure the diameter of both pins.
- Measure the distance between the pin centres.
- Measure the width between the inside faces of the ears.
If the coupler has a make or type printed on it, send that too.

What the PC118MR-8 figures mean for its attachments
- The main pump delivers up to 198 l/min at 294 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 4,750 mm. That is the deepest trench it can open.
- Komatsu offers arms from 1,850 to 2,300 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Komatsu lists buckets from 300 to 1,000 mm wide for this machine. Compare that with the bucket widths in the table above.Our sizes in that range: DB - heavy duty digging bucket (DB-120, DB-160); SDB - heavy duty skeleton DB bucket (SDB-120, SDB-160); DBF - flat-top digging bucket for quick coupler (DBF-120, DBF-160); RDBF - flat-top skeleton DBF bucket on rods (RDBF-120, RDBF-160); CB - heavy duty hydraulic clamp bucket (CBR-120)
- Komatsu lists bucket capacities from 0.093 to 0.4 m³.
- Komatsu gives a lifting capacity of 1,460 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Engine power is 72 kW.

Before you order: check the interface
The weight class of the Komatsu PC118MR-8 sizes the attachment. It does not tell you the pin diameter, the pin spacing or the stick width, and those decide whether an attachment fits. Measure them on the machine, or send us the measurements of the bucket it runs today.
A midi excavator is often the main machine on a site, trenching, loading and grading in the same day. Buyers usually start with a general purpose bucket, a grading bucket and a quick coupler, then add other tools when the work calls for them.
At this weight the choice is mostly about the material. A general purpose bucket suits soil and gravel, a reinforced bucket with thicker wear parts suits mixed ground and broken rock, and the quick coupler on the machine sets the bracket every attachment needs.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Komatsu PC118MR-8 at its weight are built with these brackets. Each code opens the models that list it.
- Measure the diameter of both bucket pins.
- Measure the distance between the pin centres.
- Measure the inside width between the stick ears.
- If the machine runs a quick coupler, note its make and type.
