These models suit machines of 40–50 tCapacity SAE [dm³]: 2,241–2,999
Standard
CW - CW-System compatible quick-coupler
The proven wedge design keeps breakout force high, and a pilot-operated check valve secures the attachment. It takes CW-system brackets in manual, automatic and tilt/swivel versions.
Candidate models by operating-weight range: CW-45, CW-45 S, CW-U-45, CW-U-45 S
These models suit machines of 25–45 t
Standard
RIP - heavy duty ripper
A single shank made of high-strength material, so it wears less. It breaks up tough soil, rock and frozen ground so the material is easier to load.
Candidate models by operating-weight range: Ripper-H
These models suit machines of 40–65 t

Before you order: check the interface
The weight class of the Liebherr R 945 Litronic (40,850 – 46,400 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.
- 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.
