Abstract:
A chain conveyor formed from a plurality of modules or links (1a, b, c; 101a) connected together by pins (2a, b) which are inserted through holes (4, 4A; 104, 104A) present in said modules or links (1a, b, c; 101a) and are each prevented from escaping by an axially counteracting element (5, 105) mounted in a seat (6, 106) also present in a said module or link (1a, b, c; 101a), said axially counteracting element (5, 105) presenting a flexible tang (5c; 105c) which intersects an end portion (4A, 104A) of the hole (4, 4A; 104, 104A) through which a pin (2a, b, c) is inserted, to thus prevent said pin withdrawing from said hole (4, 4A; 104, 104A), such withdrawal however being enabled by deflecting the flexible tang (5) while the counteracting element is mounted in the seat, the counteracting element and the seat being two separate and discrete elements that are positively but detachably engaged with each other.
