- If a bracket we made is wrong and does not fit your machine, we replace it.
How is the attachment mounted on this machine?
Tell us what is on the machine now. It narrows the sizes we show and goes with your enquiry. It does not confirm fit: we check the bracket before we send the quote.
No attachment family in our catalogue is listed above 65 t. For a machine of this weight we make the attachment to order: send us the machine details and our engineers reply with an offer.
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.
Before you order: check the interface
The weight class of the Komatsu PC800LC-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.
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.
- 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 PC800LC-8 figures mean for its attachments
- Its auxiliary circuit delivers 450 l/min. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
- The main pump delivers up to 988 l/min at 320 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 8,450 mm. That is the deepest trench it can open.
- Its maximum reach is 13,400 mm.
- It dumps at up to 8,235 mm, so a truck or skip side has to sit below that height.
- Komatsu offers arms from 2,900 to 3,600 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Komatsu lists a bucket capacity of 6.91 m³.
- Bucket breakout force is 397.2 kN and arm crowd force 326.6 kN. That is the force a bucket or ripper works with at the tooth.
- Komatsu gives a lifting capacity of 16,420 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its transport width is 4,335 mm.
- Engine power is 370 kW.
