weight capability of the C-119, the C-123, and
the C-124-, and C-130-series U.S. Air Force
aircraft.
Note.
The maximum U.S. Air Force aircraft cargo
weight and range capabilities are based on the following
conditions:
Standard day conditions
Sea level operating conditions
Hard-surfaced runways
No weather alternate required
No wind conditions
Fuel reserve
Constant cruising altitude
In the event one or more of these operating conditions
are changed, the
maximum cargo load and/or range
may be affected.
b. Shipment by Highway.
(1)
On road.
(a) Launcher. The
launcher can be moved
over highways under its own power for short
distances. It can be transported on the semi-
trailer,
tank transporter, 50-ton, 8-wheel,
M15A2, in combination with the truck, tractor,
10-ton, M123. The item can also be transported
by commercial semitrailers of adequate capacity.
Moving under its own power or loaded on a semi-
trailer, the item exceeds the legal weight and di-
mensional limits of all of the states and the
physical limitations of many highways in
CONUS and will require special permits, and at
times special routing for movement. It also ex-
ceeds the recommended weight and dimensional
limits for highway movement in oversea areas,
and special routing may be required. Movement
over public highways in CONUS should be
made only when other modes of transport can-
not be utilized.
(b) Bridge. The
bridge in its sectionalized
configuration is normally transported over the
highway loaded in the truck, stake, 5-ton (bridge
transporting). See TM 5-2510 -200-10-1 for in-
formation regarding this truck. Two trucks are
required to transport one bridge and its acces-
sories. (See para 5 for dimensions of section-
alized component) The bridge in it a assembled
configuration (scissored) can also be transported
by military and commercial semitrailers of ade-
quate capacity. See TM 5-216 for movement of
the scissored bridge by lowbed trailer. In this
configuration, the legal width limitation is ex-
ceeded in CONUS and special permits will be
required. The recommended width limitation is
also exceeded overseas, and special routing may
be required.
(2)
Off road: soils trafficability data The
vehicle
cone index (VCI) is a number which
tests have proven can be related to the char-
acteristics of a particular vehicle (see para 5).
This number, when used in connection with the
rating cone index (of the soil), can forecast the
ability of that vehicle to repeatedly cross fine-
rained soil, and sands with fines, poorly
drained. The rating cone index is obtained by
use of the cone penetrometer and its associated
equipment. See TB ENG 37 for use of the equip-
ment in the field and for interpretation of index
numbers.
c.
Shipment by Rail.
(1)
Launcher.
Loaded on a railroad flat-
car, the launcher can be transported but it ex-
ceeds the width limitations of the “Outline Dia-
gram for Single Loads, Without End Overhang,
on Open Top Cars”* for shipments within
CONUS, and verification of line clearances will
be required. In countries complying with the
Berne International Rail Interchange Agree-
ment, the launcher can be transported by rail
but it also exceeds the width and height limita-
tions, and verification of line clearances will be
required. See appendix for information regarding
blocking and restraining the launcher on railroad
flatcars.
(2) Bridge. The bridge is shipped by rail in
the sectionalized configuration and presents no
tranaportabilit y problems.
d. Shipment by Water.
1)
Launcher. The
launcher can be trans-
ported by inland waterway cargo carriers and
lighters of adequate capacity. It can also be
shipped by Mariner-, Victory-, and Liberty-class
seagoing vessels, subject to the following limita-
tions:
