The practical requirements of a jumbo include reaching the planned drilling positions, maintaining the specified hole direction and working within the available tunnel space. Matching the machine's configuration to those requirements helps establish its role in the construction cycle. The drilling system and services should be specified together with the project team.

For larger underground headings and tunnel works, defining the hole pattern and drilling depth provides a useful starting point. Access dimensions and service connections are equally relevant to the selection. UHEEM can review the catalog designation and the manufacturer's supplied configuration before matching the XUD295 to the project's drilling method.
