^{More enviromental}

Marmorok 90E is Gemsa’s DTH drill rig, is designed especially for marble quarries. Basic difference then Marmorok 90, 90 E can also work with electric power to reducing overall cost of ownership.
Drilling hole for marble wire cutting operations. Marmorok 90 E ensures continuous and uninterrupted operation ,even in the harshest conditions.

^{Non-stop operation !}

Rig has 22kW ie3 electric motor and also Deutz US EPA Tier 4 i diesel engine. Both system can be used separately while drilling or travelling the rig. In general operation , diesel engine used while travelling rig , electric power used for positioning on drill site and drilling .
If something wrong with energy supply , then you can use diesel power to continue drilling.
