Before you order: check the interface

The weight class of the Liebherr R 930 Tunnel 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.

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 Liebherr R 930 Tunnel Litronic 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.
