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 ZX890-7G figures mean for its attachments
- The main pump delivers up to 1,024 l/min at 319 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 8,870 mm. That is the deepest trench it can open.
- Its maximum reach is 13,820 mm.
- It dumps at up to 9,080 mm, so a truck or skip side has to sit below that height.
- Hitachi offers arms from 2,950 to 3,700 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Hitachi lists buckets from 1,590 to 2,260 mm wide for this machine. Compare that with the bucket widths in the table above.
- Hitachi lists bucket capacities from 2.9 to 5 m³.
- Hitachi gives a lifting capacity of 26,200 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 14,800 x 4,450 x 4,770 mm (length, width, height).
- Engine power is 377 kW.

Before you order: check the interface
The weight class of the Hitachi ZX890-7G 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.
