What the ZX250-300-350-7 STRAIGHT BOOM figures mean for its attachments
- Its auxiliary circuit delivers 30 l/min. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
- The main pump delivers up to 448 l/min at 343 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 6,030 mm. That is the deepest trench it can open.
- Its maximum reach is 10,630 mm.
- It dumps at up to 8,870 mm, so a truck or skip side has to sit below that height.
- Its arm is 2,960 mm long.
- Hitachi lists bucket capacities from 0.8 to 1.4 m³.
- Hitachi gives a lifting capacity of 8,750 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 10,700 x 3,190 x 3,150 mm (length, width, height).

Before you order: check the interface
The weight class of the Hitachi ZX250-300-350-7 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.
At this weight the choice is mostly about the material. A general purpose bucket suits soil and gravel, a reinforced bucket with thicker wear parts suits mixed ground and broken rock, and the quick coupler on the machine sets the bracket every attachment needs.
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 ZX250-300-350-7 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.
