Abstract
A mobile articulated conveyor apparatus includes a plurality of modular carriages pivotally interconnected to each other to enable relative articulated movement between adjacent carriages about upstanding pivot axes generally normal to the longitudinal axes of the carriages. Each carriage has a pair of drive wheels intermediate its length, and drive motors are carried by selected ones of the carriages to effect driving rotation of the drive wheels on each carriage. A belt guidance arrangement is interposed between the adjacent ends of each pair of pivotally interconnected carriages and cooperates with idler roller assemblies to guide an endless conveyor belt along the length of the conveyor apparatus. The belt guidance arrangements enable bending of the belt in generally horizontal planes upon relative articulated movement between the carriages while maintaining the belt in predetermined trained relation on the carriages.
