SAFETY
3-1. GeneralGeneral safety considerations and precautions
formovement during loading operations are as follows:
a. Check the entire semitrailer to insure that allloose items
are properly secured.
b. Make sure no personnel or obstacles are in theway before
moving the semitrailer.
c. When backing or moving the semitrailer inconfined areas, make
sure appropriate guides toassist are visibly posted.
WARNINGFire extinguishers must be readily availableduring all
loading and unloading.
WARNINGProper ventilation must be provided whenloading and
unloading if prime mover engineis used. Prolonged inhalation of
carbonmonoxide fumes will produce adverse effectsthat may prove
fatal.

AIR TRANSPORTABILITY GUIDANCE
Section I. GENERAL
4-1. ScopeThis chapter provides transportability guidance forair
movement of the semitrailers described in chapter2. It covers
significant technical and physicalcharacteristics and safety
considerations; prescribesthe materials required to prepare, load,
and unloadthe semitrailers as internal loads aboard US AirForce
aircraf; and provides examples of tiedowndiagrams and tiedown data
tables for loading thesesemitrailers in C-130, C-141, and C-5
aircraft.
4-2. Maximum Utilization of AircraftCargo may not be carried in
or on the bed of thesemitrailers unless approval of the specific
load hasbeen obtained from the Air Force. Such cargo mustbe
securely restrained in the trailer bed either byattachment to the
semitrailer or to the aircraft andmust meet the same restraint
criteria as required forthe semitrailer. No cargo may be carried in
thetanker semitrailer. When loading and securing cargoin the bed of
the semitrailer, the load must notexceed the maximum rated
cross-country loadcapacity, and consideration must be given to
theaircraft allowable cargo load (ACL) and com-patibility of cargo
items. The weight of thesemitrailer plus the weight of any cargo it
maycontain must be accurate. The semitrailer and itscargo are
considered as one package and the grossweight is used to determine
tiedown requirements inaccordance with paragraph 4-40, TM
55-450-15. Ifthe semitrailer is to carry any cargo when it is in
theaircraft, load and then weigh the semitrailer before itis loaded
in the aircraft. The weight of any cargoloaded on a semitrailer
will change the center ofgravity (CG) of the semitrailer as shown
in chapter2. Determine the new CG in accordance withparagraph 3-4,
TM 55-450-15. Chapter 3 and 4 ofTM 55-450-15 contain detailed
instructions for loadplanning and aircraft loading.
4-3. SafetyIn addition to the safety precautions contained
inchapter 3, the following should be noted:
a. The activity offering the semitrailers for airtransport will
notify the aircraft commander or his
designated representative if ammunition or ex-plosives are to be
transported on or within a par-ticular semitrailer.
b. The semitrailer must be restrained for airtransport in
accordance with the applicableprocedures in section IV of the
appropriate USAF-9Technical Order.
c. Each semitrailer must be checked carefully toinsure that all
loose items are properly secured inaccordance with restraint
criteria.
d. Cargo tanks of tanker semitrailers must beemptied and purged
prior to loading on aircraft.
e. All fuel must be drained from the fuelsegregator assembly of
tanker semitrailers that areequipped with filter separators.
WARNINGProper ventilation must be provided whenloading and
unloading. Prolonged inhalationof carbon monoxide fumes may be
fatal.
WARNINGFire extinguishers must be readily availableduring all
loading and unloading operations.
CAUTIONDo not allow vehicles to exceed 3 miles perhour (walking
speed) on loading ramps orinside aircraft.
NOTECargo loads depicted in this manual arerestrained to the
required minimum of 3gforward restraint. This must be increased toa
minimum of 8g forward restraint whenpassengers or nuclear weapons
cargo arecarried forward of the other cargo.
NOTEIn air loading, the center of gravity of eachvehicle must be
determined, and whereweight and/or measurement is critical,
eachvehicle should be weighed and/or measured.
4-4. ResponsibilityThe aircraft commander or his representative
isresponsible for insuring that the load is secured inaccordance
with restraint criterial outlined in theapplicable aircraft
technical order.

M270-series.c. C-5: All series covered in this manual.
4-6. Typical LoadsThe following tiedown diagrams (fig 4-1
through 4-3)and data (tables 4-1 through 4-3) are based on
ac-ceptable methods and can be used as a guide forloading and
securing the semitrailers aboard theaircraft. Loads are based on
empty vehicles in areduced configuration without major
sec-tionalization. Figures 4-1 through 4-3 show a typicaltiedown
pattern of a representative semitrailer forlogistical movement;
similar patterns are applicableto the other types of semitrailers
covered in thismanual. Appropriate prime movers are required
forloading and unloading, and TM 55-2320-260-15-1and/or TM
55-2320-211-15-1, as appropriate, shouldbe consulted if prime
movers are to be transportedwith the semitrailers. Tables list the
type andcapacity of tiedown devices required, location pointson the
semitrailers, and aircraft fittings to which thedevices are
secured.
4-7. Material RequirementsShoring and bracing materials will be
provided bythe shipping activity, and the following must
beaccomplished prior to final securing of thesemitrailer:
a. Using 2- by 4-inch lumber, cut-to-suit, con-struct a brace
cradle (stanchion) to be placed underthe kingpin area for
additional support (item G, fig6-2).
b. Prior to lowering the semitrailer landing legs tothe aircraft
floor, place a double layer of ¾-inch-thick, 1½- by 6-foot plywood
under the landing legs.
4-8. Piggyback Loads for C-5 AircraftTo maximize aircraft loads
and to gain trans-portation economies, the M127-, M172-, M269-,and
M270-series semitrailers, when reduced to theirminimum height, can
be stacked on top of each otherin the upright position. The removed
side, rear, andfront panels or body cargo stakes of this type
ofsemitrailer, when properly banded, can be placed onthe cargo deck
of the lower semitrailer. This type ofload must receive specific
approval by the Air Forceand must adhere to the applicable
requirements ofparagraph 4-2 above.

CHAPTER 5
HIGHWAY AND OFF-ROAD TRANSPORTABILITY GUIDANCE
5-1. ScopeThis chapter provides transportability guidance
forhighway and off-road movement of the semitrailersdescribed in
chapter 2. It covers general technicaland physical characteristics
and safety con-siderations required for safe transport of
thesesemitrailers.
5-2. SafetyIn addition to the safety precautions contained
inchapter 3, the semitrailers are subject to all thesafety
regulations applicable to commercial carrierswhen moving over
public highways in CONUS. Inoversea areas, movements are governed
by theaterand local regulations.
5-3. Movement on Own WheelsThe semitrailers covered in this
manual are designedto be towed by a prime mover such as the 5-ton,
6x6,truck, tractor, M52, M818, or by a similar vehicleequipped with
a fifth wheel, an air supply, and a 24-volt electrical system. In
the case of the M172A1semitrailer, the 10-ton, truck, tractor, M123
isrecommended. The semitrailers are designed to betowed over
prepared roads at up to 50 miles per hour(mph) and over unimproved
roads and open rollingterrain at up to 30 mph. For reasonable
distances,therefore, the desirable method of land movement ofthe
semitrailers would be by use of an appropriateprime mover. Figures
5-1 and 5-2 show turning-
characteristics diagrams of the M131A4 semitrailertowed by the
M52 tractor and of the M270A1semitrailer towed by the M246 tractor,
wrecker.Similar turning characteristics are applicable to theother
types of semitrailers of similar size covered inthis manual.
5-4. LimitationsThe semitrailers described in this manual
exceedCONUS legal width limitations of 96 inches andtherefore
require special highway permits. In somestates the legal length
limitations are also exceeded,and consequently the local
installation trans-portation officer should be consulted for
ap-propriate clearance. The procedures for obtainingspecial permits
in CONUS are outlined in AR 55-162.Legal limits of oversea areas
are identified in “Limitsof Motor Vehicle Sizes and Weights,”
InternationalRoad Federation, 1023 Washington Building,Washington,
D. C. 20005.
5-5. Piggyback TransportThe M127-, M172-, M269-, and
M270-seriessemitrailers, when reduced to their minimum height,can
be piggybacked on another semitrailer of thesame series. The
semitrailer can be stacked on top ofanother either in the upright
or inverted position.However, if long-distance hauling is
required,transport by rail is recommended (see chapter 7).

CHAPTER 6
MARINE AND TERMINAL TRANSPORTABILITY GUIDANCE
6-1. ScopeThis chapter provides transportability guidance
formarine and terminal movement of the semitrailerslisted in
chapter 2. It covers significant technical andphysical
characteristics and safety considerations;prescribes blocking
materials; and provides guidancerequired to prepare, lift, tie
down, and discharge thevehicles.
6-2. SafetyIn addition to the safety precautions contained
inchapter 3, the following precautions should be takenas
applicable:
a. All vessel equipment and gear should be in-spected prior to
use.
b. All stevedore slings and other items used in theloading and
unloading operations should be in-spected for condition and
adequate capacity.
c. All personnel should be cautioned not to walkunder
semitrailers being lifted.
d. Lifting provisions on each semitrailer should beinspected to
insure that they are complete andundamaged.
e. All lifts should have at least two tag linesattached to
control the swing of the semitrailer whilesuspended.
6-3. General Rules for StowingWhenever possible, semitrailers
should receive theprotection of below-deck stowage. In general,
goodstowage of vehicles means placing them fore and aft
as close together as practical, with minimum spacingbetween
outer vehicles and the sweatboards (ap-proximately 4 to 6 inches).
Removable parts (such asside, rear, and front panels or body cargo
stakes),spare parts, and on-equipment materiel (OEM), ifnot shipped
on the trailer, should be protected andidentified for location or
disposition during ship-ment. Semitrailers in the hold of the ship
should beblocked in front, in the rear, and on both sides of
thewheels so that the vehicle cannot move in anydirection;
individual vehicle blocks should be bracedto bulkheads, stanchions,
and other vehicle wheelblocks. Additionally, a brace cradle
(stanchion)should be placed under the kingpin for
additionalsupport. All semitrailers should be lashed with wirerope
or chains to nearby bulkheads, stanchions, orpadeyes.
NOTEThe methods described in this chapter forlifting and
securing vehicles are suggestedprocedures. Other methods of
handling andstowage may be used provided they willinsure safe
delivery without damage.
a. Lifting. For location of lifting points on thesemitrailers
refer to the side and rear elevationdrawings in paragraph 2-4 (fig
2-8 through 2-17);however, due to the length of the semitrailers,
aheavy-lift spreader is normally used. For a typicallifting diagram
see figure 6-1.

b. Loading. Vehicles of any type are alwaysloaded on vessels in
their minimum configuration–that is, reduced height, with or
without cargo.Semitrailers can be loaded over the beach or
frompiers onto landing craft, beach discharge and am-phibious

using a prime mover ora crane. Semitrailers can be loaded by using
a primemover on roll-on/roll-off vessels or onto the deck of
barges from a pier when tidal conditions are suitableand ramps
are available, they can also be loaded ontosea going vessels by
shoreside or floating cranes.Jumbo booms and heavy-lift ship’s gear

CHAPTER 7
RAIL TRANSPORTABILITY GUIDANCE
Section I. GENERAL
7-1. Scope 7-2. Maximum Utilization of RailcarsThis chapter
provides transportability guidance for Additional cargo, as
approved by the activity of-rail movement of the semitrailers
described in fering the semitrailers for transport, may be
trans-chapter 2. It covers significant technical and ported with
the trailers.physical characteristics and safety considerationsand
prescribes the materials and guidance toprepare, load, tie down,
and unload the semitrailers.
Section II. TRANSPORT ON CONUS RAILWAYS
7-3. GeneralThe transportability guidance contained in
thissection is applicable when the semitrailers aretransported on
CONUS railways. Consideration isgiven to single multiple movements
on the types ofrailcars normally used for the movement of
thesesemitrailers. The semitrailers, when loaded onsuitable
railcars, can be transported without majorsectionalization or major
disassembly, except for theM128- and M129-series semitrailers,
which have anonreducible height limitation requiring verificationof
line clearances. These semitrailers, therefore, willrequire special
routing under the provisions ofrestricted rail movements. All other
semitrailers,when at their respective reduced heights,
aretransportable when within the limits of theAssociation of
American Railroads “OutlineDiagram for Single Loads, Without End
Overhang,on Open-Top Cars, ” as shown in both the RailwayLine
Clearance Publication and the Official RailwayEquipment
Register.
7-4. Preparation of VehiclesThe degree of preparation for the
semitrailers priorto being transported by railcar is dependent upon
theoperational commitment.
7-5. Loading Semitrailers on General-PurposeFlatcars
a. Semitrailers may be placed in the tiedownposition of the
railcar by a crane or side loader, orthey may be driven on towed
onto the railcar, if asuitable ramp or bridge is available.
b. The load shown in figure 7-1 is based on aflatcar minimum
width of 9 feet 6 inches, which willaccommodate all semitrailers
described in chapter 2except for the semitrailers, low-bed, M172
andM172A1, which will require a car minimum width of10 feet 3
inches. Figure 7-2 is a blocking and tiedowndetail diagram for
figure 7-1. Table 7-1 is a bill ofmaterials for blocking and
tiedown of thesemitrailers, and table 7-2 provides data
concerningthe application of materials required for
securingsemitrailers on general-purpose flatcars.
NOTEA staggered nailing pattern should be usedwhen lumber or
laminated lumber is nailed tothe floor of the railcar.
Additionally, thenailing pattern for an upper piece oflaminated
lumber will be adjusted asrequired so that a nail for that piece
will notbe driven through, onto, or right beside anail in the lower
piece of lumber.

7-6. Loading Semitrailers on Special-PurposeFlatcars
a. Semitrailers can be shipped more efficiently onspecialized
railroad freight equipment such as theTTX-type flatcars with
retractable hitches (fig 7-3).Whenever possible, shippers should
request thistype of flatcar when shipping semitrailers.
b. Loading may be accomplished in the samemanner as outlined in
paragraph 7-5a above.
c. This method of loading is applicable to othertypes of
semitrailers weighing up to 40,000 pounds
providing that the kingpin height is between 47inches minimum
and 52 inches maximum.
d. Figures 7-4 and 7-5 show typical loads ofsemitrailers on a
flatcar with retractable hitches.
CAUTIONInsure that retractable hitch is securelylocked in UP
position. Securement of thetrailer on the retractable hitch will be
inaccordance with the car owner’s in-structions. Check to insure
that trailerkingpin is locked in place on the hitch.

GENERAL INSTRUCTIONS
1. Tires are to be inflated to 10 psi above highway operating
pressures.2. When No. 8 gage, black, annealed wire is used for
tiedown purposes, the wire is to be threaded in a continuous length
until all the
required number of strands are formed (one complete loop
consists of two strands).3. If semitrailers are shipped in a loaded
condition and the combined weight of the vehicle and cargo exceeds
18,000 pounds, ad-
ditional securement will be required as follows: Increase the
wheel tiedowns to eight strands of No. 8 gage black, annealed wire
( i t e mP). Add chock blocks (item B) against front and rear of
each inside wheel.
4. Item L should be positioned 6 inches behind kingpin of
semitrailer.5. Trailer landing legs (landing gear) shall be raised
to provide a minimum of 3 inches of clearance between the landing
legs and
car.6. See General Rules 2, 3, 4, 5, 7, 9, 10, 14, 15, and 19B
appearing in section I of the General Rules Governing the Loading
of Com-
modities on Open Top Cars and Trailers published by the
Association of American Railroads for further details.

7-7. Double-Decking of Semitrailersa. The M127, M172, M269, and
M270 series
flatbed semitrailers, when reduced to their minimumheight, can
be double-decked on top of another in aninverted position. The
removed side, rear, and frontpanels or body cargo stakes should be
properlybanded and can then be accommodated and securedon top of
the lower semitrailer and/or car floor.
b. For this type of load, hardwood separators (2-in. x 6-in. x
length-to-suit) should be located
crosswise between the gooseneck and trailer body.Two such blocks
should be placed at each end.
c. The double-decked trailers should be secured toeach other by
10 pair (5 or each side) of ties loopedthrough the trailer stake
pockets. Each tie consistsof eight strands of No. 8 gage black,
annealed wire(fig 7-6). A substitute for this wire can be
3/8-inchwire rope, attached in a complete loop in the samemanner
and secured with three 3/8-in. cable clips(clamps).

Section III. TRANSPORT ON FOREIGN RAILWAYS
7-8. GeneralThe transportability guidance contained in
thissection is applicable when the semitrailers describedin chapter
2 are transported on foreign railways.Consideration is given to
single and multiplemovements on the types of railcars normally used
forthe trasport of this type of equipment. Allsemitrailers, except
the M128-, M129-, and M131-series, can be transported in their
reduced heightconfiguration within European countries complyingwith
the International Loading Gauge (formerlyBerne International)
without restrictions; this alsoapplies to the majority of the
countries in the MiddleEast as well as to South America, Australia,
India,and Pakistan. Because of the height of the M128-,M129-, and
M131-series semitrailers, specialclearance will be required for
local railwayauthorities. In the Middle East and South Americathe
clearances vary, and each country will require a
separate check. In Australia, India, and Pakistan,wide- or
broad-gauge railways provide greaterclearances and less
restrictions. Because of thevarious designation systems used by
differentcountries, foreign railcars are difficult to classify.
Inaddition, clearances vary between countries andwithin a country.
Consequently, careful evaluationof transport capability must be
made on an in-dividual basis.
7-9. Transport on US Army-Owned Foreign ServiceFlat cars
a. General. The semitrailers can be transported ona number of US
Army-owned foreign service flat-cars. These flatcars are provided
exclusively for thetransport of US military materiel. Table

suitable fro transporting this equipment.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take
publicly available information, slap “watermarks” and other junk on
it, and sell it. Those masters of search engine manipulation make
sure that their sites that sell free information, come up first in
search engines. They did not create it... They did not even scan
it... Why should they get your money? Why are not letting you give
those free manuals to your friends?
I am setting this document FREE. This document was made by the
US Government and is NOT protected by Copyright. Feel free to
share, republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can,
please provide a link to liberatedmanuals.com, so that free manuals
come up first in search engines:
