The weight class of the Liebherr R 921 Litronic 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.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Liebherr R 921 Litronic 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 R 921 Litronic figures mean for its attachments
- The main pump delivers up to 432 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 48 hydraulic. The bracket on every attachment has to match the coupler.
- It digs down to 6,620 mm. That is the deepest trench it can open.
- Its maximum reach is 9,780 mm.
- It dumps at up to 6,800 mm, so a truck or skip side has to sit below that height.
- Its arm is 2,900 mm long.
- Liebherr lists buckets from 850 to 1,400 mm wide for this machine.Our sizes in that range: DB - heavy duty digging bucket (DB-230); SDB - heavy duty skeleton DB bucket (SDB-230); DBF - flat-top digging bucket for quick coupler (DBF-230); RDBF - flat-top skeleton DBF bucket on rods (RDBF-230); DSX - Nordic heavy duty digging bucket (DS-HD-250); CB - heavy duty hydraulic clamp bucket (CBR-260)
- Liebherr lists bucket capacities from 0.6 to 1.5 m³.
- Bucket breakout force is 159 kN and arm crowd force 113 kN. That is the force a bucket or ripper works with at the tooth.
- Liebherr gives a lifting capacity of 4,700 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 9,750 x 2,980 x 3,200 mm (length, width, height).
- Engine power is 112 kW.
