Abstract

An alignment assembly is coupled between a steering assembly and a support foot to maintain an alignment of the support foot with the load transport assembly while the steering mechanism rotates in different steering directions. A biasing device activates in response to non-linear displacements of the load transport assembly relative to the support foot and moves the steering assembly and the support foot back into original alignments with the load transport assembly. The alignment assembly may include a lower main gear assembly that rotates the support foot relative to the steering assembly and an upper main gear assembly that rotates the steering assembly relative to the load transport assembly.
