Welded to EN ISO 3834-2. Agree it as a standing term of supply and the EN 10204 3.1 certificate ships with every attachment. You also get the CE declaration of conformity for every attachment. See the certificates.
Message us on WhatsAppPhotos and voice notes are welcome.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.
Before you order: check the interface
The weight class of the Hitachi ZX33U-6 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.
On a mini excavator the weight of the attachment counts for more than on a larger machine, because every kilogram of bucket is taken from lift capacity and stability. A narrow trenching bucket and a wide grading bucket are the usual pair, and many machines run a small quick coupler to change between them.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Hitachi ZX33U-6 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 ZX33U-6 figures mean for its attachments
- The main pump delivers up to 76.8 l/min at 245 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 3,130 mm. That is the deepest trench it can open.
- Its maximum reach is 5,040 mm.
- It dumps at up to 3,100 mm, so a truck or skip side has to sit below that height.
- Hitachi offers arms from 1,170 to 1,520 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Hitachi lists bucket capacities from 0.08 to 0.09 m³.
- Bucket breakout force is 27.2 kN. That is the force a bucket or ripper works with at the tooth.
- For transport it measures 4,450 x 1,550 x 2,530 mm (length, width, height).
- Engine power is 18.8 kW.
