The attachments buyers in your market ask for first, sized for the SY390H.
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 SY390H.

What the SY390H figures mean for its attachments
- Its auxiliary circuit delivers 550 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 704 l/min at 343 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 7,473 mm. That is the deepest trench it can open.
- Its maximum reach is 11,022 mm.
- It dumps at up to 7,746 mm, so a truck or skip side has to sit below that height.
- Its arm is 3,200 mm long.
- Sany lists a bucket capacity of 1.9 m³.
- Bucket breakout force is 233 kN and arm crowd force 184 kN. That is the force a bucket or ripper works with at the tooth.
- For transport it measures 11,432 x 3,190 x 3,783 mm (length, width, height).
- Engine power is 252 kW.

Before you order: check the interface
The weight class of the Sany SY390H 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 Sany SY390H 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.
