Liebherr's 150t class R9150B in a UK quarry.

A pair of 138t Liebherr R9150B excavators working in a UK quarry digging un-blasted chalk for the cement industry. The excavators are used to break the stone up to stop it blocking the static crusher. They load 40-50t capacity trucks as the opening to the crusher is too small for a larger truck. As blasting is not allowed on site, the time in-between loading trucks is spent digging and prying material loose.
