Abstract
A conveyor construction that includes a conveyor frame assembly formed from a pair of spaced side frame members interconnected with each other by spaced cross members. The upper bed of the conveyor frame assembly is formed from individual bed plate strips attached to each of the cross members. The width of the conveyor frame assembly can be modified by the proper selection of the number of bed plate strips. The conveyor frame assembly includes a separate tensioning assembly and tracking adjustment assembly. The tracking adjustment assembly is adjusted separate from the tensioning assembly such that additional tension applied to the conveyor belt does not affect the previously selected tracking adjustment. The conveyor construction includes a center drive unit having only a single drive roller, a guide roller and a tensioning roller. The tensioning roller position is controlled by a pair of spaced tensioning cylinder.
