Diameter Roll Paper on End Using Rubber Mats Approved by DAMAGE PREVENTION & FREIGHT CLAIM COMMITTEE Association of American Railroads Issued May 2013 Published by Association of American Railroads/TTCI Damage Prevention and Loading Services DOT Road Pueblo, CO (Printed in U.S.A.) 2013

2 GENERAL RULES The General Rules relating to personal safety and the safe operation of trains, contained in AAR Circular Nos. 42-K and 43-E or supplements thereto, issued by the Association of American Railroads, must be observed. These loading rules and/or practices apply to shipments transported in the USA, Canada and Mexico. The loading methods in individual closed car loading publications issued by the Damage Prevention and Loading Services Section of the Association of American Railroads are minimum standards that have been evaluated and approved. These minimum standards offer practical guidelines on the subjects covered. Since these are minimum standards, it may be necessary to supplement these methods in some instances. Securement standards in AAR closed car loading publications are intended for safe transit of the rail car from origin to destination and prevention of lading and equipment damage. These standards do not address unloading practices. This approval may be withdrawn if the loads using these methods exhibit consistent load failure during actual shipments. Loading and bracing methods not presently approved may receive consideration for approval and publication under Section II - Evaluation of New Loading and Bracing Methods and Materials for Closed Cars, Trailers or Containers of General Information Bulletin No. 2, Rules and Procedures for Testing of New Loading and Bracing Methods or Materials. Submit requests to Director Damage Prevention and Loading Services, AAR/TTCI, DOT Road, Pueblo, CO GENERAL Use these loading methods for 47 in. to 50 in. diameter roll paper loaded on end in a 1-1 offset pattern in a trailer or container for intermodal service. This method was originally tested in a 100 in. inside width container with roll widths (height) of 63 in., 72 in, and 94 in., representing 8 roll, 7 roll, and 6 roll load patterns respectively. Use side wall fillers to maintain a 1-1 offset pattern. Plan the load to equalize the weight on each side of the trailer or container. Because roll weights vary, this will require attention to pre-planning. A balanced load is required for the stability and success of this loading method. Loads with an odd number of rolls have the first roll centered against the front end wall with fillers on both sides of sufficient size and strength to prevent lateral roll movement. NOTE: Due to the nature of this concept, some edge and/or header damage could occur due to roll rocking. If this is objectionable, do not use this loading and bracing method. For all methods depicted, the rubber mats must extend a minimum of 6 beyond the nose of the last roll in both directions. Illustration Nos. 73E-G: 1. Use rubber mats of the type and thickness specified in the following table for Illustration Nos. 73E-G. Only the following rubber mats have been evaluated and found acceptable for this loading method: Name Thickness Description Vendor TransMat in. 2 ft wide rolls AIA Down River, an ITW company Specifications for this rubber mat is in Appendix D of the Intermodal Loading Guide. 2. Divide the load into two sections, each containing approximately half of the load. Use the 6, 7, or 8 roll pattern depicted in Illustration Nos. 73E-G. The width of the rolls is to be at least 6 in. less than the inside height of the trailer/container. 1

3 3. Load the first section in a 1-1 offset pattern starting at the nose using closed cell honeycomb filler panels or other suitable filler along both side walls to initiate and maintain the 1-1 offset pattern. Place fillers, with 1,500 lb. minimum crush strength, on edge between the sidewall and each of the rolls. Thickness of filler is dependent on trailer inside width and actual roll diameter. Use industrial tape or other means to keep fillers in position. Fillers must extend at least 2 ft. beyond where the roll makes contact in either direction. If using multiple void fillers in tandem, unitize them to restrict independent movement. 4. When three rolls are loaded in the nose section of a 7 roll load, load the first roll so it is centered in the trailer against the nose. Place void fillers 3 in. x (void width) x 42 in. corrugated fiberboard with a 1,500 lb. minimum crush strength, on both sides of the first roll and the side walls. If using multiple void fillers in tandem, unitize them to restrict independent movement. See Illustration 73F. 5. For rolls greater than 72 in. in width, use a minimum of 5 in. deep by 22 in. wide by 60 in. tall fillers between the first roll loaded and the nose of the trailer or container. Use industrial tape or other means to keep fillers in position. 6. Load the second section also in a 1-1 offset pattern split from the first to provide proper lengthwise weight distribution. The rearmost roll in this section should be at least 3 ft. from the doors when loading is completed. 7. Load each roll on 2 ft. wide mats centered under each roll and extending a minimum of 6 beyond the nose of the roll in both directions. Do not secure the mats to the trailer floor. NOTE: Do not use rubber mats if torn or otherwise damaged. 8. Use Type 1A, Grade 4 nonmetallic strap for unitizing each section. For 3 roll sections where the first roll is centered at the front end wall, unitize only the second and third rolls. For roll widths 63 in. or less, unitize each section with one strap located approximately 12 in. below the top of the rolls; for roll widths 64 in. to 72 in., use 2 straps located 12 in. and 20 in. below the top of the rolls; for roll widths greater than 72 in., use 3 straps located 12 in., 20 in., and 28 in. below the top of the rolls. Use the correct buckle in accordance with manufacturer s instructions (see Intermodal Loading Guide, Section III-F for approved polyester cord strapping). Tension and seal straps using proper tensioning and sealing tools. Use strap hangers or tape attached to the rolls to maintain proper strap alignment. CAUTION: Ensure that the floor of the trailer is not overloaded when loading wide rolls. The load may not exceed 2,500 lb./linear ft. lengthwise of the trailer for any 1 ft. section.
