The utility model discloses an advanced hydraulic support with a rotatable and self-resetting top beam. A main body structure of the support comprises a base, a stand column, the top beam, a stand column and base fixing buckle and a top beam rotatable and self-resetting mechanism, the base comprises a base body, a stand column left pressing block and a stand column right pressing block. The standcolumn comprises a stand column cylinder body, a telescopic rod body and a stand column ball head. The top beam comprises a top beam body, a stand column socket, a top beam rotatable self-resetting mechanism limiting plate, a top beam rotatable self-resetting mechanism fixing pin hole and a pin shaft fixing clamping groove. The top beam rotatable self-resetting mechanism comprises a stand column ball head limiting ring and a resetting elastic washer. According to the advanced hydraulic support with the rotatable and self-resetting top beam, the support top beam can rotate by a large angle under the condition that the support top beam adapts to a roadway roof; the posture of the top beam can be automatically reset after the support is lowered, and the problems that an existing advanced hydraulic support is poor in roadway roof connecting effect, low in supporting efficiency, prone to breakage of a top beam pin shaft, prone to falling of the top beam and the like can be well solved.
