device for transporting and lifting of kappenbögen for roadway in underground mining and tunnel construction

摘要

An overhead conveyor is used to carry structural members for forming arched mine gallery supporting frames. Members (19) attached to the gallery roof form a track for a travelling carriage (10) from which is supported a tilting beam (1) with a carrier (14) for the structural members. Attached to the foremost part of the roof mounted member (19) is lifting tackle (24) with a chain (41, 44) attached to the beam at a point between the carrier and the pivot axis (3) under the support (48) on the carrier (14) is a tie rod (6) parallel to the beam.
