A carriage including an articulated caster is disclosed. The carriage supports a load and includes a frame with a load-supporting section, base sections, and a linkage that permits relative pivotal movement therebetween. The linkage includes a transverse section that pivotally interconnects at least two of the base sections and a longitudinal section that pivotally interconnects the transverse section and the load-supporting section. The linkage permits relative pivotal movement so that at least two of the carriages may cooperatively support the load and substantially share the load over an uneven surface.
