How is the attachment mounted on this machine?
Tell us what is on the machine now. It narrows the sizes we show and goes with your enquiry. It does not confirm fit: we check the bracket before we send the quote.
These machines weigh more than 80 t, the limit of what we build to order. Send us the machine details and we tell you what we can build.
Before you order: check the interface
The weight class of the Hitachi ZX890LCH-7 / ZX890LCR-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.
- 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 ZX890LCH-7 / ZX890LCR-7 figures mean for its attachments
- The main pump delivers up to 1,112 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 1,870 to 2,260 mm wide for this machine.
- Hitachi lists bucket capacities from 3.5 to 5 m³.
- Hitachi gives a lifting capacity of 36,370 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 14,900 x 4,450 x 4,770 mm (length, width, height).
- Engine power is 382 kW.
