1. (a) The maximum permit weight for any single axle, not connected to another axle by a weight equalizing suspension system, must not exceed 30,000 pounds or 850 pounds per inch of tire width, whichever is less.
2. (b) The maximum permit weight for any group of axles on a crane will be determined by calculating the "W" weight for the group, using the formulas in Appendix B, "Maximum Permit Weight Formulas," as shown in subsection (g) of this section, and comparing the calculated "W" weight with the corresponding "W" weight that is established in Appendix A, "Maximum Permit Weight Table," as shown in subsection (g) of this section.
3. (c) The maximum permit weight per inch of tire width for axles that are steerable must not exceed 950 pounds, and the maximum permit weight per inch of tire width for axles that are not steerable must not exceed 850 pounds.
4. (d) A crane that does not have any group of axles that exceeds the limits established in Appendix A, "Maximum Permit Weight Table," and Appendix B, "Maximum Permit Weight Formulas," as shown in subsection (g) of this section, will be permitted with a single-trip or time permit for travel on any route that does not include a load restricted bridge.
5. (e) A crane that has any group of axles that exceeds the limits established by Appendix A, "Maximum Permit Weight Table," and Appendix B, "Maximum Permit Weight Formulas," as shown in subsection (g) of this section, will be eligible, on an individual case by case basis, for a single-trip permit only; permit approval or denial will be based on a detailed route study and an analysis of each bridge on the proposed travel route to determine if the route and bridges are capable of sustaining the movement.
6. (f) A bridge that has been analyzed and determined to be incapable of sustaining the crane will be excluded from the permit route.
7. (g) The table entitled, "Maximum Permit Weight Table," is Appendix A, and the list of formulas entitled, "Maximum Permit Weight Formulas," is Appendix B. The indicated appendices are shown as follows.
