Roof Master 2.0. AR-DE

SWK-AR-DE (Diesel/Electric) roof bolter.

Poland SWK-AR-DE (Diesel/Electric) roof bolter articulated machine has been specially designed for the drilling requirements of Lubin mine by Mine Master and J.H.Fletcher - USA.

It combines the maneuverability of an articulated chassis, the tramming capacibility of a diesel engine and powerschif transmission, and possibility of drilling from either the diesel engine or electric motor. In order to achieve this versatility, the machine is equipped with two main hydraulic pumps: one powered from the diesel engine and the other from the electric motor. In addition each power source drivers a blower that is used for the dust collection system. The first unit sold Lubin cooper mine in November 1999. From very beginning our machine had been accepted by user, and as a result of above we received order for next machine.
