Drilling Rig MI28

DESCRIPTION

Drilling rig for water wells, mineral exploration, geothermal applications, coring, seismic, it is the most representative in the Massenza’s production range as although the moderate dimensions it has high technical characteristics in terms of pull-up and torque. For these reasons the rig can reach high depths, around (700m) and it is possible to work by mud pump 7”1/2 x 8”, which vastly improves drilling 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.
