Abstract
A flexible mobile bridge conveyor has a plurality of carriages connected to each other to form a train. Each carriage has an axle with wheels mounted on opposite ends thereof and encased in a housing. A first frame section is fixedly connected to the axle housing, and a second frame section has a proximal end pivotally connected to the first frame section so as to be pivotal about both a horizontal, longitudinal pivot axis and a horizontal, transverse axis. Linkage mechanisms are coupled to the first and second frame sections, for coupling adjacent carriages, so as to provide pivot movement about a vertical axis. This combination of linkages provides three degrees of freedom in order to enable the flexible mobile bridge conveyor to negotiate uneven roadway surfaces while following curved trajectory in the direction of movement.
