Abstract
The invention relates to a conveyor apparatus, particularly for intra-plant conveyance, comprising a conveyor rail system and a plurality of carrier units straddling the rail from below and resting thereon through rollers for travelling along at least one inclined conveyor stretch with the aid of a driven endless conveyor chain. On approaching the conveyor chain, coupling members on the carrier units come into engagement with the chain links. The invention improves the engagement of the coupling members to ensure reliable conveyance of the carrier units even after extended periods of operation of the conveyor apparatus. A tilting member is mounted between the arms of the carrier unit and is provided with projections at a mutual spacing adapted to the pitch of the chain in such a manner that as one of the projections enters a chain opening, so as to engage a chain link portion with its engagement face, a second projection has its bearing face engaged by a chain link portion between adjacent chain openings.
