ABSTRACT:
A work turnover conveyor for stone slabs and the like. The conveyor in its normal position includes, in continuation, a work input section, a work turnover section, and a work output section. The work turnover section is comprised of first and second segments each of which is arranged to be pivoted arcuately about an axis at right angles to the conveyor section axis. A slide guide is arranged laterally along the first and second segments forming the work turnover section, and hydraulic cylinders are provided for pivoting the first and second segments downwardly at their free ends to a substantially vertical disposition with the respective ends of the segments accordingly being spaced apart one from the other at opposed ends of the slide guide so as to form a U-shaped cradle, thus achieving turnover of the stone slab upon continued articulation of the conveyor to the normal position.
