Abstract: A pusher for scraper chain conveyors comprising an upper and lower member, the two members being connectable by bolted connections. Each member of the pusher featuring one part of one or more chain beds through which a flat jointing plane runs, as well as one part of the recesses provided for the bolts of the bolted connections and located to the outside of the chain bed. The upper and lower member embracing each other at least partially, and the upper member being configured as a bow-like bridge element that wraps over both ends of the lower member from above. The two ends of the bridge-like upper member being of cuneiform shape and having upper and lower guide surfaces sloping towards each other in V-formation, and the upper and lower member engaging each other at each end by nose-like centering projections on the upper or lower member, the projections engaging complementary recesses in the contact surfaces of the lower or upper member.

Abstract: Pusher for scraper chain conveyors, especially for underground mining In a pusher for scraper chain conveyors, which comprises an upper and a lower part, the upper part is designed as a bow-like bridge element the ends of which wrap over the ends of the lower part from above in clasp-like manner.

Abstract: A two part scraper for a chain conveyor has upper and lower parts joined along a horizontal dividing surface. The surface contains bar and groove interlocking means and at least a pair of chain beds for securing the scraper to a link of the chain.
