At least one jacking cylinder is coupled to the second end of the base assembly. The scanner subassembly includes a mounting member movably coupled to the linear bearing, a rotating member pivotally coupled to the mounting member, an elongate radial bearing coupled to the mounting member, and a carriage assembly movably coupled to the radial bearing. The carriage assembly includes a scanner arm, and the scanner arm includes an inspection probe coupled to each end of the arm. The scanner arm is configured to be parallel to the radial bearing.
