Abstract

A method for loading tube bundles on a railcar includes placing the tube bundles lengthwise on the car and stacked above the bed of the car to form tube bundle packs. The packs are separated by panels. A spacing block is configured to go within the longitudinally extending remaining space left over after loading a finite number of packs. This spacing block include parallel plates which are rigidly displaced one from another by blocks. Padding is arranged on the outer side of the plates and the panels. Padding is arranged on the bulkheads as well. The panels and spacing block may be tied to the railcar through boards and dunnage.

Claims (21)

1. A method for loading tube bundles on a railcar having a bed and bulkheads, comprising

placing the tube bundles lengthwise on the bed and stacked above the bed to form packs of multiple tube bundles between the bulkheads;

affixing resilient sheet material to either side of panels;

placing the panels with the resilient sheet material at ends of the packs of multiple tube bundles;

closely abutting the packs and the panels at ends of packs on the bed between the bulkheads with little or no longitudinal space thereamong to leave a final longitudinal gap with all of said packs loaded on the railcar between two adjacent ones of said packs or between one of the bulkheads and the most adjacent pack;

configuring a spacing block including fixing parallel plates rigidly displaced one from another and affixing resilient sheet material to either side of the spacing block to fill the final longitudinal gap;

positioning the spacing block on the bed in the final longitudinal gap.

2. The method of claim 1 , placing the tube bundles to form packs and closely abutting the packs further including placing the panels in seriatim pack by pack.

3. The method of claim 1 further comprising

affixing resilient sheet material to the bulkheads.

4. The method of claim 3 , placing the tube bundles to form packs and closely abutting the packs and panels including, for the first two of said packs, abutting the bulkheads.

5. The method of claim 4 , placing the panels and closely abutting the packs and panels further including, for the first two of said panels, abutting the first two packs, respectively.

6. The method of claim 5 , placing the tube bundles to form packs and closely abutting the packs and panels further including, for a subsequent two of said packs, abutting the first two panels.

7. The method of claim 6 , placing the panels, placing the tube bundles to form packs and closely abutting the packs and panels including further continuing in seriatim, for the subsequent one of said panels and packs until insufficient longitudinal space remains for additional tube bundles.

8. The method of claim 7 , the configuring and positioning the spacing block being in seriatim after insufficient longitudinal space remains for additional tube bundles.

9. The method of claim 1 further comprising

fixing the panels on the railcar.

10. The method of claim 9 , fixing the panels on the rail car including nailing the panels to dunnage among the adjacent one of said tube bundles.

11. The method of claim 1 , configuring the spacing block including fabricating the parallel plates with wood blocks extending therebetween, the parallel plates being plywood.

12. The method of claim 1 , the resilient sheet material being woven hemp rope forming mats.

13. The method of claim 12 , the resilient sheet material being about one-half inch thick.
