The attachments buyers in your market ask for first, sized for the SK380SRLC-7.
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.

What the SK380SRLC-7 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 6,990 mm. That is the deepest trench it can open.
- Its maximum reach is 10,820 mm.
- It dumps at up to 8,680 mm, so a truck or skip side has to sit below that height.
- Kobelco offers arms from 2,400 to 3,100 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Kobelco lists buckets from 1,300 to 1,490 mm wide for this machine. Compare that with the bucket widths in the table above.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 a bucket capacity of 1.2 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 17,670 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its tail swing radius is 1,900 mm, which matters beside a wall or in a live traffic lane.
- For transport it measures 9,980 x 3,190 x 3,510 mm (length, width, height).
- Engine power is 198 kW.

Before you order: check the interface
The weight class of the Kobelco SK380SRLC-7 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.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Kobelco SK380SRLC-7 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.
