Abstract: The drlling machine has a bogie accommodated within a gantry frame, the gantry frame carrying the drilling tools and the jacks. In the drilling position and in the gantry position of the machine the gantry frame bears by the jacks upon the ground and with the jacks lifted off the ground the frame bears upon the bogie. The drilling machine has a mechanism for lifting the bogie and a beam with a mechanism effecting displacement of the beam in a direction transverse to the longitudinal geometric axis of the bogie, as well as projectable abutments onto which the gantry frame bears in the transportation position of the drilling machine, the frame having flexible operative connection with the bogie lifting mechanism.

Abstract: The herein-proposed drilling boom is provided with a telescopic manipulator mounted with its one end on the bearing plate with a possibility to turn round the vertical axis while hinged to its other end is a feed with drifter, said feed being provided with a crowd hydraulic cylinder. Besides, rigidly secured on the vacant end of the manipulator is a head carrying the hydraulic cylinders for tilting and turning the feed in a horizontal plane and a rotational mechanism adapted to turn the feed round the axis of the rotational mechanism. The drilling boom is also provided with hydraulic cylinders for lifting and turning the manipulator in a horizontal plane.
