Gallery Vault Drilling - Marini Quarry Votager Operating And Maintenance Manual

Gallery vault drilling

It's possible to perform drilling operations on gallery vaults.
To use this work mode, the column must be repositioned on the roller bearing.
1) Position the column horizontally.
2) After the column is supported: Loosen the 8 fastening nuts on the
roller bearing and the 2 on the feed cylinder (fig. 64).
3) Remove the column, rotate it and reposition it on the roller
bearing.
The cylinder connection must now be on the side of the slide
support beam (fig. 65).
4) Reposition the gibs and tighten the previously removed nuts.
