Machine MVK and its modifications are equipped with self- propelled chassis and are intended for mechanization of screw-type roof bolting construction in mine workings.
Availability of two drives – diesel and electrical allows to use the machine most effectively both in mine workings which are ventilated due to the general air-pressure drop and in dead-end mines which are dangerous because of gas and dust contents. Design of the machine makes it possible to connect additionally both electrical (127 V) and pneumatic (up to 10 bar) equipment.
This product is certified and has Permissions of Rostekhnadzor and Gospromnadzor of the Ministry of Emergency Situations of Republic of Belarus to application in the mines which are dangerous because of gas and dust contents.
