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.
Before you order: check the interface
The weight class of the Komatsu PC290LC/NLC-10 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.
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.
Heavy excavators dig rock, load trucks and work in quarries, so wear decides the bucket as much as capacity does. Rock and reinforced buckets carry thicker wear steel, teeth and side cutters, and the bucket is sized to the trucks it loads and to the density of the material.DBS - engineered rock bucket for excavator
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Komatsu PC290LC/NLC-10 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.

What the PC290LC/NLC-10 figures mean for its attachments
- The main pump delivers up to 479 l/min at 373 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 7,220 mm. That is the deepest trench it can open.
- Its maximum reach is 10,770 mm.
- It dumps at up to 8,985 mm, so a truck or skip side has to sit below that height.
- Komatsu offers arms from 2,000 to 3,500 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Komatsu lists a bucket capacity of 2.02 m³.
- Bucket breakout force is 211.8 kN and arm crowd force 172.6 kN. That is the force a bucket or ripper works with at the tooth.
- Komatsu gives a lifting capacity of 6,050 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 10,185 x 3,290 x 3,340 mm (length, width, height).
- Engine power is 159 kW.
