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 Liebherr R 972 Litronic (68,450 – 77,550 kg) 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.
- 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 R 972 Litronic (68,450 – 77,550 kg) figures mean for its attachments
- The main pump delivers up to 820 l/min at 350 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Liebherr lists this quick coupler for it: SWA 92 hydraulic. The bracket on every attachment has to match the coupler.
- It digs down to 12,500 mm. That is the deepest trench it can open.
- Its maximum reach is 16,800 mm.
- It dumps at up to 10,600 mm, so a truck or skip side has to sit below that height.
- Liebherr offers arms from 2,600 to 5,000 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Liebherr lists buckets from 1,400 to 2,450 mm wide for this machine. Compare that with the bucket widths in the table above.
- Liebherr lists bucket capacities from 2 to 5.5 m³.
- Bucket breakout force is 354 kN and arm crowd force 308 kN. That is the force a bucket or ripper works with at the tooth.
- Liebherr gives a lifting capacity of 21,800 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 12,850 x 4,495 x 3,900 mm (length, width, height).
- Engine power is 330 kW.
