Spacer using spacing bags and method for loading tube packs on railcars
View Patent ↗A method and apparatus for loading tube bundles on a railcar includes placing the tube bundles lengthwise on the car and stacked above the car to form packs. These packs are spaced longitudinally one from another on the car. Spacing bags are placed within the longitudinally extending spaces. Plates are displaced one from another by the spacing bags to push against the ends of the packs.
1. A method for loading tube bundles on a railcar having a bed, comprising:
placing the tube bundles lengthwise on the bed placing at least one plate adjacent to a longitudinal end of the tube bundles and,
inflating at least one spacing bag adjacent to the at least one plate.
2. The method of claim 1 further comprising placing resilient material on at least one side of the at least one plate.
3. The method of claim 2 wherein the resilient material comprises a cushioning material.
4. The method of claim 3 wherein the cushioning material is applied to both sides of the at least one plate.
5. The method of claim 1 further comprising partially deflating the at least one spacing bag prior to inflating the at least one spacing bag adjacent to the at least one plate.
6. The method of claim 5 wherein the at least one spacing bag is inflated to about 7 to 12 PSI.
7. The method of claim 5 wherein the at least one spacing bag is inflated to about 10 PSI.
8. The method of claim 1 further comprising providing strapping at the bed of the rail car and the strapping extending over the spacing bag.
9. The method of claim 8 wherein the strapping extends over the at least one plate positioned between the spacing bag and the tube bundles.
10. The method of claim 8 wherein the at least one spacing bag is inflated to exert pressure against the tube bundles so that a semi-rigid unit is created.
11. The method of claim 1 further comprising securing a covering to the rail bed and extending the covering over the tube bundles and the spacing bag.
12. The method of claim 1 further comprising a second spacing bag that is placed above the at least one spacing bag and inflated to apply pressure against the tube bundles.
13. The method of claim 1 wherein the at least one plate is rigid and is coupled to the rail car bed.
14. The method of claim 1 wherein the at least one plate is coupled to the spacing bag.
15. The method of claim 14 wherein the at least one plate is placed on at least two sides of the spacing bag.
16. The method of claim 15 wherein the at least one plate is secured by a flexible material.
17. The method of claim 16 wherein the spacing bag is inflated to exert pressure against the tube bundles.
18. The method of claim 15 wherein the spacing bag and the at least one plate comprises a unit which is inserted between ends of the tube bundles; and
inflating the spacing bag to push the at least one plate against the ends of the tube bundles.
19. A method of loading tube bundles on a rail car having a bed and bulkheads, comprising:
placing a first and a second tube bundle lengthwise on the bed;
placing at least two plates between the first and the second tube bundle; and
inflating at least one spacing bag between the at least two plates to push the at least two plates against the first and second tube bundles.
20. A method to loading tube bundles on a rail car having a bed and bulkheads, comprising:
placing tube bundles lengthwise on the bed
placing at least one plate adjacent to a longitudinal end of the tube bundles; and
partially deflating at least one spacing bag prior to inflating the at least one spacing bag adjacent to the at least one plate.
21. A method of loading bundles on a rail car having a bed and bulkheads, comprising:
placing tube bundles lengthwise on the bed and placing at least one plate adjacent to the tube bundles;
inflating at least one spacing bag adjacent to the at least one plate; and,
securing strapping to the bed of the rail car and extending the strapping over the top of a spacing bag.
22. A method for loading material on a rail car having a bed, comprising:
placing two tube bundles lengthwise on the bed; and
placing a first and a second spacing bag between the first and the second tube bundles and inflating a spacing bag to exert pressure against the first and the second tube bundles.
23. A method of loading material on a rail car having a bed, comprising:
placing tube bundles lengthwise on the bed and providing a spacing bag and at least one plate;
inserting the spacing bag and the at least one plate adjacent to the tube bundles; and
inflating the spacing bag to push the at least one plate against the tube bundles.
