The conventional installation of shield suppports in faces to be developed and the alignment and positioning of the shields represents a considerable physical strain for and hazard to the workers employed. Therefore, a slewing and positioning device was developed which is used to transload the shield supports in the face from the transport facility, to turn them into direction of face advance and to position them. The slewing and positioning device includes the actual slewing facility and two pusher frames at both sides serving as abutments for the slewing facility. The overall advice is advanced by using these frames. The device was tested in use at Walsum colliery in the Robert seam under extremely difficult conditions with a seam inclina...
