Abstract
A process to transport and assemble a drilling or workover rig substructure. The process includes the steps of transporting a driller side substructure section and an off driller side substructure section to a rig site so that the sections are spaced from and parallel to each other. A center substructure section is transported to the rig site. The center substructure section is moved into a space between the driller side and the off driller side sections. The center substructure section is thereafter connected to the driller side and to the off driller side subsections. A floor of the driller side substructure and a floor of the off driller side substructure are raised while both connected to the center substructure section from a transport position to a use position while maintaining the floors parallel to the bases.
