Chain scraper extractor - has integral plane guide for mining extraction operations

摘要

Slide distance pieces located between chain channels (10) form the cross-cut bar (16) which is a component of an angle rail (3) which with its arm (4') is fitted to the groove shield of the chain scraper extractor (2). The extractor arm (6) supporting on the ground (5) against working thrust forms a track for the plane and/or the face cutting machine. The extending arms (4) of the angle rail (3) are extended upwards by releasable side plates (21), and covering hoods (19) at their vertex are pref. connected to the side plates by screws. The side plates (21) form an upper guide for the plane. USE - In mining work, as a guide for a plane in a chain scraper extractor.
