Section No. 1--General Rules (Rev.-9-1984)
(2)
High tension bands, less than .031 inch thickness must have a percentage of elongation in 6 inches from 5
to 16 percent inclusive. High tension bands .031 inch thickness or over, must have a percentage of elongation in 6
inches from 6.5 to 16 percent inclusive and ductility as contained in the ASTM Specification D3953 (latest edition).
(3)
High tension bands encircling pile must be machine tensioned and sealed on top of the load, when
possible, and located as far away from end of load as practical.
(4)
High tension bands attached to stake pockets must be sealed no closer than 18 inches from top of stake
pockets. (See Sketch 3. Paragraph (j).)
(5)
Free ends of bands must not extend more than 12 inches from seals.
(6)
When a long free span exists between points of attachment of high tension bands, a dampening
arrangement to prevent excessive vibration of bands must be applied midway between points of contact, by tying bands
to sides of box, crate, lading, etc., with common annealed wire.
(7)
High tension bands should be applied to packages and/or loads with markings facing outward.
(8)
The welding of high tension bands is prohibited except where required In the process of manufacturing.
(9)
The use of second hand or reclaimed high tension bands for such Items specified in the rules and detailed
figures is prohibited. A high tension band that has been tensioned and is cut or broken becomes a second hand band
and must not be reused In the preparation of new loading or in the readjusting of loads.
(10)
1 in. x .031 in. punched steel anchor banding, minimum breaking strength 3500 lbs. may be used to
secure loose or boxed materials to car floors.
(c)
Wire-High Tension and Common.
(1)
High tension wires must have a percentage of elongation In 10 inches from 6.5 to 16 percent inclusive.
(2)
When common annealed wire is used for securement purposes, the method of tying, tightening and
determining the number of strands is to be in accordance with "Examples For Tying" as shown in General Rule 10. Twist
wire taut with rod, bolt, pipe or appropriate length of 2 inch x 2 inch piece of lumber and secure to prevent unwinding.
(3)
High tension wires encircling pile must be machine tensioned and twist tied on top of load, when possible,
and located as far away from end of load as practical.
(4)
High tension wire attached to stake pockets, lading strap anchors or other means of attachments must be
machine tensioned. The location of the twist tie or washer attachment must not exceed 6 inches from point of
anchorage.
(5)
The use of secondhand or reclaimed high tension wire or common wire for such Items specified in the rules
and detailed figures is prohibited.
(d)
Wire Rope/Cable.
(1)
Where wire rope/cable is specified under detailed figures, the ends must be overlapped a minimum of 12
inches and must be secured with the number of "U" bolt cable clips as shown in the tables.
(2)
The wire rope/cable must be protected at-all sharp corners and/or sharp edges. Where thimbles are used
to prevent sharp turns and protect wire rope/cable from sharp edges, they must be secured with a "U" bolt cable clip.
Tighten wire rope/cable with turnbuckle or suitable tensioning device or twist taut with rod, bolt or pipe and secure to
prevent unwinding.
(3)
Wire rope/cable. when used, should he located so that they are not in contact with each other When
cables do contact each other, suitable means to prevent chafing or wear of these items must be provided.
(e)
Band and/or Wire Protectors.
(1)
Band and/or wire protectors sufficient to provide a suitable radius must be used to protect bands and wires
at stake pockets, slotted holes In car sides and at all points having sharp edges on either equipment or lading. Protectors
must be applied so as to prevent dislodgement. High tension bands, when used as protectors. must be secured to tie
bands by sealing. In so far as possible, the carriers should furnish cars with stake pockets and anchorage holes or slots
rounded to the extent that the protectors are not required to protect sharp corners at such points of attachment. When
cars in this condition are not available, the carrier should arrange to either grind off the sharp edges on such anchorage
details or weld rounded metal thereon having a radius of at least 3/10 inch before cars are placed for loading. In cases
where cars are placed for loading which do not have the sharp edges corrected on such details, the shipper and carrier
shall negotiate as to the proper procedure to be followed.
(2)
Band protectors, made of formed treated hardboard and/or composition material must not be used under
load securement bands and or unitizing bands on loads of steel sheets or plates. Metal protectors only are acceptable for
this purpose.
(3)
Where reference is made to "Protection angles, 20 gage, 4 inches wide applied so as to prevent
displacement" in the specifications of any figure in Section No. 2, the use of manufactured edge protectors giving
equivalent band protection is permissible except for locations in General Rule 15(e)(2).
