Start here

The attachments buyers in your market ask for first, sized for the ZX350LC-7 / ZX350LCN-7.

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.

Send me the spec sheet for my machine

Pick a bucket line and we email you its spec sheet, with the sizes we build for the ZX350LC-7 / ZX350LCN-7.

What the ZX350LC-7 / ZX350LCN-7 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 576 l/min at 343 bar. That is the pump output of the whole machine, not the flow an attachment gets.
Hitachi lists this quick coupler for it: CW, pin grabber and S-coupling. The bracket on every attachment has to match the coupler.
It digs down to 7,380 mm. That is the deepest trench it can open.
Its maximum reach is 11,020 mm.
It dumps at up to 9,230 mm, so a truck or skip side has to sit below that height.
Hitachi offers arms from 2,670 to 3,200 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
Hitachi lists bucket capacities from 1.15 to 1.86 m³.
Bucket breakout force is 246 kN. That is the force a bucket or ripper works with at the tooth.
Hitachi gives a lifting capacity of 20,280 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
Its transport width is 3,190 mm.
Engine power is 210 kW.

Hitachi ZX350LC-7 CTA 25m and 30m	35.2 t	not published	576 l/min
Hitachi ZX375US-7	35.6 t (+0.4 t)	6,920 mm (-460)	472 l/min (-104)

ZX350LC-7 / ZX350LCN-7: what the brochure names

Features Hitachi names in its own brochure for the ZX350LC-7 / ZX350LCN-7. Some of them may be optional, so check the machine's spec before you order.

Telematics for tracking the machine remotely (ConSite).
A two-piece boom.
Operator protection certified to ROPS and FOPS.
Work modes you select from the cab.

Before you order: check the interface

The weight class of the Hitachi ZX350LC-7 / ZX350LCN-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 ZX350LC-7 / ZX350LCN-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.
