Abstract
1,135,813. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. 28 July, 1966 [30 July, 1965], No. 33987/66. Heading E1E. In an advancing mine roof support comprising two frames A, B arranged in parallel and alternately advanced by a jack having a cylinder 16 and twin pistons the floor rails 11 of the frames are bolted to transverse girders 24 which are coupled respectively to the cylinder 16 and to a longitudinal girder 23 connected to the piston rods 19, 20 and extending over the cylinder 16. Each transverse girder has a set of joint eyes 33 which are connected to a set of co-operating joint eyes on the associated cylinder or longitudinal girder 'by horizontal pins 32. The transverse girders have channels to receive pressure hoses.
