ABSTRACT:
A guided transport unit and methods of guiding the transport unit for moving a superstructure in precise angular movements over a surface are disclosed. The guided transport unit comprises a skid pad, a vertical displacing member engaged with the skid pad, a base operatively associated with the vertical displacing member, and a directional actuator. The base includes a planar element for engaging the surface over which the superstructure is transported, and a carrier for moving the vertical displacing member and skid pad relative to the surface. The directional actuator controls and secures the relationship among the vertical displacing member, the base, and the skid pad for positioning the base in a predetermined direction to engage the surface, setting the carrier to move each skid pad in a predetermined direction across the planar element of the base, and repositioning the base in another direction for movement of the guided transport unit.
