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.
These machines weigh more than 80 t, the limit of what we build to order. Send us the machine details and we tell you what we can build.
Before you order: check the interface
The weight class of the Kobelco SK850LC-11 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 SK850LC-11 figures mean for its attachments
- The main pump delivers up to 1,008 l/min at 330 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 10,700 mm. That is the deepest trench it can open.
- Its maximum reach is 15,230 mm.
- It dumps at up to 8,870 mm, so a truck or skip side has to sit below that height.
- Kobelco offers arms from 2,900 to 5,400 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Kobelco lists buckets from 1,370 to 2,500 mm wide for this machine.
- Kobelco lists bucket capacities from 2.3 to 5.4 m³.
- Bucket breakout force is 403 kN and arm crowd force 234 kN. That is the force a bucket or ripper works with at the tooth.
- Kobelco gives a lifting capacity of 30,390 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its tail swing radius is 4,580 mm, which matters beside a wall or in a live traffic lane.
- For transport it measures 14,530 x 3,640 x 4,790 mm (length, width, height).
- Engine power is 382 kW.
