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 EC550E figures mean for its attachments
- The main pump delivers up to 832 l/min at 338 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Volvo lists this quick coupler for it: Volvo hydraulic quick coupler S3. The bracket on every attachment has to match the coupler.
- It digs down to 7,690 mm. That is the deepest trench it can open.
- Its maximum reach is 12,430 mm.
- It dumps at up to 7,850 mm, so a truck or skip side has to sit below that height.
- Volvo offers arms from 2,550 to 3,900 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Volvo lists buckets from 1,710 to 2,190 mm wide for this machine. Compare that with the bucket widths in the table above.
- Volvo lists bucket capacities from 2.4 to 4.2 m³.
- Volvo gives a lifting capacity of 20,970 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its tail swing radius is 3,880 mm, which matters beside a wall or in a live traffic lane.
- For transport it measures 12,240 x 3,400 x 3,910 mm (length, width, height).
- Engine power is 340 kW.

Before you order: check the interface
The weight class of the Volvo EC550E 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 Volvo EC550E 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.
