Magorian Mine Services used a WS 30 to excavate a wine
cavern in the Napa Valley, California.
The TCU was mounted to a Cat 416 backhoe loader to
excavate the tunnels through the volcanic ash; a task
traditionally carried out using costly roadheading equipment.
The caverns are used to store wine throughout the fermentation
and maturing process. Being underground the temperature
remains stable, a prerequisite for the production of
a good vintage.
The TCU achieved over 10 feet of driveage per 9-hour
shift, curring accurate tunnel profiles in preparation
for the application of a stabilising shotcrete layer.
The TCU can also be used to trim back the shotcrete
prior to the application of a finishing concrete layer. |
