Beschreibung
Zusammenfassung:	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. The peculiar constructional feature of this drilling boom lies in the fact that its manipulator-actuating hydraulic cylinder and the feed crowd cylinder are controlled by the respective servomechanisms, each of said servomechanisms being provided with a servodrive having a rod coaxially mounted on which are hydraulic cylinders the rod-end space or piston-end space of each of said cylinders communicating with the respective rod-end space or piston-end space of the hydraulic cylinder controlled by the servomechanism said spaces being equal in volume.
