The weight class of the Kobelco SK300LC-11E 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 SK300LC-11E figures mean for its attachments
- The main pump delivers up to 490 l/min at 343 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 8,100 mm. That is the deepest trench it can open.
- Its maximum reach is 11,630 mm.
- It dumps at up to 9,250 mm, so a truck or skip side has to sit below that height.
- Kobelco offers arms from 2,400 to 4,000 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Kobelco lists buckets from 800 to 1,420 mm wide for this machine.Our sizes in that range: DB - heavy duty digging bucket (DB-400); DBF - flat-top digging bucket for quick coupler (DBF-400); DSX - Nordic heavy duty digging bucket (DS-HD-400)
- Kobelco lists bucket capacities from 0.6 to 1.4 m³.
- Bucket breakout force is 208 kN and arm crowd force 139 kN. That is the force a bucket or ripper works with at the tooth.
- Kobelco gives a lifting capacity of 16,150 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its tail swing radius is 3,300 mm, which matters beside a wall or in a live traffic lane.
- For transport it measures 10,710 x 3,190 x 3,260 mm (length, width, height).
- Engine power is 198 kW.
