Abstract
A friction drive system floor conveyor includes a tubular guide rail laid along a conveyor line, a tubular support rail laid directly above, and disposed in parallel relation to, the tubular guide rail, multiple inverted J-shaped carriers having rollers pivoted freely at their upper ends for engagement with the upper side of the support rail, and a pair of guide rollers freely pivoted at the lower end to engage opposite sides of the guide rail, a driven bar linking bases of the carriers, a carriage support bracket installed upright on the driven bar, and a friction drive disposed along the conveyor line. The friction drive system floor conveyor achieves a stable conveyance with low noise, and without roll or rattling while conveying heavy materials or articles, simplifies system construction, and facilitates system maintenance.
