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 ZX490LCH-7 figures mean for its attachments
- The main pump delivers up to 770 l/min at 319 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 7,700 mm. That is the deepest trench it can open.
- Its maximum reach is 11,770 mm.
- It dumps at up to 7,720 mm, so a truck or skip side has to sit below that height.
- Hitachi offers arms from 2,500 to 3,400 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Hitachi lists buckets from 1,560 to 1,820 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-500); SDB - heavy duty skeleton DB bucket (SDB-500); DBF - flat-top digging bucket for quick coupler (DBF-500); RDBF - flat-top skeleton DBF bucket on rods (RDBF-500)
- Hitachi lists bucket capacities from 2.1 to 2.5 m³.
- Hitachi gives a lifting capacity of 18,240 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 12,010 x 3,820 x 3,710 mm (length, width, height).
- Engine power is 296 kW.

Before you order: check the interface
The weight class of the Hitachi ZX490LCH-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 Hitachi ZX490LCH-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.
