LOADING AND UNLOADING ABLE PAYLOAD WITH MINE CLEARING BLADE ATTACHED (CONT)
Ensure that chains are positioned inboard of both curbside and streetside curb
guides or damage to equipment may occur when payload is loaded.
Chains may vary slightly in length. Ensure that chains used at front of semitrailer
are the same length and are properly laid out or payload may contact gooseneck
and cause damage to equipment.
Some early semitrailers were issued with 3/4-inch link size chains of different
lengths than the 1/2-inch link size chains on most semitrailers. This procedure
describes tiedown with 1/2-inch link size chains only.
This procedure requires four 25-ton shackles, two additional 19-foot (5.8m) chains,
two additional 11-foot (3.4m) chains, and Military Load Classification (MLC) data
plate not authorized in TM 9-2330-381-14 Basic issue Item (BII) List. These items
must be acquired through Additional Authorization List (AAL), Appendix B, of this
With chains crossed so chain from streetside tiedown ring crosses over chain
from curbside tiedown ring, oval end links of both chains should be in front of
outboard edge of payload chocks.
(22) Arrange payload tiedown chains as follows:
(a) Select two 11-foot (3.4m) tiedown chains (16) and loop through two front tiedown rings recessed in
(b) Hook tiedown chains (16) to themselves such that both chains have 39 links between hook and oval
(c) Position tiedown chains (16) so oval end links are in front of outboard edge of front payload chocks (9
(d) Lay tiedown chains (16) so they are crossed near front of platform with chain from streetside tiedown
ring over chain from curbside tiedown ring.
