FIELD: mechanisms.
SUBSTANCE: invention relates to powered support elements position monitoring devices. Disclosed is face support cantilever beam (10) turning position determination method, which by means of, at least, one hydraulic cylinder (14) can be turned about axis relative to face support cap (12) between retracted position and extended position, characterized by fact, that determining pressure in hydraulic cylinder annular space (24) and/or in piston space (26) and depending on determined pressure making conclusion on turning position.
EFFECT: technical result is providing accuracy of cantilever support turning position determining without need for arrangement of necessary components in face support potentially hazardous zone.
