  • Patent number: 6763936
    Abstract: A chain conveyor formed from a plurality of modules or links (1a, b, c) connected together by pins c2a, b) which are inserted through holes (4, 4A) present in the modules or links (1a, b, c) and are prevented from escaping by axially counteracting elements (5) mounted in seats (6) also present in the modules or links (1a, b, c), in which the axially counteracting elements (5) present a flexible tang (5c) which, when the axially counteracting element is mounted in the seat (6), intersects an end portion (4A) of the holes (4, 4A) through which the pin (2a, b, c) is inserted, to thus prevent the pin withdrawing from the holes (4, 4A), such withdrawal however being enabled by deflecting the flexible tang (5).
