The weight class of the Atlas AC 18UF 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 Atlas AC 18UF at its weight are built with these brackets. Each code opens the models that list it.
Brackets we build attachments with in this weight range. Not a confirmed fit.
- 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 AC 18UF figures mean for its attachments
- The main pump delivers up to 62 l/min. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 2,210 mm. That is the deepest trench it can open.
- Its maximum reach is 3,850 mm.
- It dumps at up to 2,560 mm, so a truck or skip side has to sit below that height.
- Atlas lists a bucket capacity of 0.04 m³.
- Bucket breakout force is 22.7 kN and arm crowd force 9.8 kN. That is the force a bucket or ripper works with at the tooth.
- Atlas gives a lifting capacity of 268 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 3,580 x 990 x 2,400 mm (length, width, height).
- Engine power is 14 kW.
