FIELD: transport.SUBSTANCE: invention relates to conveyors for loose materials, particularly, to chains used in piggy-back conveyor. Link chain comprises multiple separate links. these are arranged so that first link comprises two rod parts, two arc-like parts for their connection that along with said two rod parts define the first link inside. At least one separator extending inward from inner surface of one of two rod parts and inward from inner surface of the other rod part divides said inside into two zones of displacement. Note here that separator joint point with at least one rod part is not located at the rod part centre. Said separator is S-shaped at has larger cross-section at the point of joint with every rod part than that at its mid part. Second link gas two rod parts to connect their two arc-like parts. The latter and two rod parts confine the zone of displacement in side said second link. Note also that second link is engaged with first link to displace in one of two displacement zones in first link.EFFECT: decreased weight, higher strength of chain link.6 cl, 9 dwg |
