Patent ID: 6983838

Claim:
A modular construction system for a conveyor for conveying article carriers including pallets or skids, longitudinally or transversely, comprising: lateral longitudinal carriers; transverse frame elements which connect the longitudinal carriers and have supporting feet; and driven load-bearing conveying means for the article carriers, wherein the longitudinal carrier, which accommodates the conveying means, is a respective torsionally substantially rigid hollow profile which can be connected in a releasable manner to a transverse frame element and is designed for optionally accommodating one of driven load-bearing rollers and insertable sliding plates for a load-bearing belt, the hollow profile being open on one of its longitudinal sides for the purpose of accommodating the load-bearing rollers and being at least partially closed on the opposite longitudinal side in order to form a rest for the sliding plate, and wherein, by virtue of the hollow profile being rotated through 180° about its longitudinal axis, the longitudinal side for the selected purpose in each case can be oriented in a use position relative to the transverse frame element.
