Abstract

Equipment for adjusting the position of a self-advancing hydraulic roof support on rising longwall faces consisting of side by side arranged support units each including a floor base on which are pivotably mounted two hydraulic props. The props which are positioned behind each other support a cap with their free end for supporting the roof. The position of the support units is adjusted by a diagonally positioned hydraulic cylinder pivotably mounted with one end in vertical support at the gob side end of the base and pivotably attached with other end to the roof cap between front prop and rear prop of the support unit. The adjusting movement of the cylinder is initiated by a contactor mounted on the rear prop and activates a valve positioned on the vertical support of the base.
