CONVEYOR STRUCTURE

摘要

A conveyor structure (1, 20) is disclosed that is capable of being retracted concertina fashion for transport on a trailer (42) between sites of operation. The structure comprises a plurality of H-frames each comprised of rigid supports (2A, 2B or 21, 22) joined by a cross-member (3) which supports rollers (3A-D, 30) upon which the conveyor belt (4) travels. Extensible links (6), and cross-braces (25, 26) maintain the longitudinal and lateral rigidity of the structure.
