An articulating carriage for moving an object across a surface having a non-planar obstruction to allow movement of the object over the obstruction. The articulating carriage has a walking beam assembly that pivotally supports a pedestal to dispose a support surface thereof above the walking beam assembly. The walking beam assembly has a base plate, wheeled casters and a pair of spaced apart hangers having articulation openings. The walking beam pivots relative to the pedestal. In one embodiment, the pedestal is pivotally mounted on the walking beam assembly. In another embodiment, a pair of walking beam assemblies are connected with a crosstube that pivotally supports the pedestal. In another embodiment, a major crosstube assembly connects a pair of crosstubes to define a carriage having four walking beams. In yet another embodiment, a compound crosstube assembly connects pairs of major crosstube assemblies to define a carriage having eight walking beams.
