DRILLING RIG Mi40
DESCRIPTION
Drilling rig for water wells, mineral explorations, seismic, coring and deep geothermal applications.
Although its moderate dimensions it has high technical characteristics in terms of pull up and torque: for this reason the rig able to reach high depths (around 800 m).
It is possible to work by mud pump 71/2×8 which vastly improves drilling also in bad terrain conditions. Its versatility permits to adopt various drilling methods: direct and reverse circulation by mud and by down the hole hammer. The rig can be either crawler or truck mounted and it can be operated remotely.
