Marini MR-4 Down the Hole Drill
The MR–4 is a hydraulic drilling unit which allows you to make large size holes (up to 255 mm) for down the hole drilling.
It’s light and strong tubular structure allows it to be positioned and used on slopes and working places with difficult access. Four stabilizers improve the stability of the machine.
The unit is run by means of a hydraulic power pack (powered by an electric, diesel or petrol motor) which can easily be removed from the tubular structure. The unit can be equipped with a rotary head mod. ID 300 and also with separate roto-percussion rock drills up to 58 kg.
Like all Marini units, the MR–4 can be customized in relation to the different needs.
