<p>A scraper chain conveyor has pushing members with an upper and lower part shaped to prevent relative lateral movement in the direction of travel. The members are complementary shaped, with recesses and cooperating protrusions on either part, respectively. The parts have grooves to avoid conveyor protrusions that contribute to part wear and cooperating chain beds that retain a chain link when coupled together. Spaces between the coupled parts permit a pretensioning force applied to the coupled parts. The upper part bridges the lower part to improve the stability of the part coupling. The parts include wear indicators and can relieve strain introduced on the chain conveyor from larger drive sprockets.</p> |
