The support frame extends along the entire length of the longwall working, and has a pair of generally parallel longitudinal beams interconnected by a plurality of transverse beams. The roof support units are positioned between the longitudinal beams, and are supported on the transverse beam. Each of the longitudinal beams comprises a plurality of beam sections pivotably connected together end-to-end.
