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.
Before you order: check the interface
The weight class of the Volvo EC300 Straight Boom 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
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Volvo EC300 Straight Boom 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.

What the EC300 Straight Boom figures mean for its attachments
- The main pump delivers up to 552 l/min at 333 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 6,150 mm. That is the deepest trench it can open.
- Its maximum reach is 11,580 mm.
- It dumps at up to 9,835 mm, so a truck or skip side has to sit below that height.
- Volvo offers arms from 3,050 to 3,200 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Bucket breakout force is 190 kN and arm crowd force 136 kN. That is the force a bucket or ripper works with at the tooth.
- Volvo gives a lifting capacity of 11,490 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its tail swing radius is 3,125 mm, which matters beside a wall or in a live traffic lane.
- For transport it measures 11,175 x 3,190 x 3,135 mm (length, width, height).
- Engine power is 189 kW.
