The weight class of the Komatsu PC600/LC-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.DBS - engineered rock bucket for excavator

What the PC600/LC-8 figures mean for its attachments
- The main pump delivers up to 820 l/min at 318.7 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 8,490 mm. That is the deepest trench it can open.
- Its maximum reach is 12,800 mm.
- It dumps at up to 7,960 mm, so a truck or skip side has to sit below that height.
- Komatsu offers arms from 2,900 to 3,500 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Komatsu lists a bucket capacity of 5.25 m³.
- Bucket breakout force is 336.4 kN and arm crowd force 271.6 kN. That is the force a bucket or ripper works with at the tooth.
- Komatsu gives a lifting capacity of 12,250 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 11,830 x 4,210 x 4,600 mm (length, width, height).
- Engine power is 323 kW.
