CHAPTER 5

HIGHWAY TRANSPORTABILITY GUIDANCE

Section I. GENERAL

5-1. Scope

This chapter provides transportability guidance for highway movement of the disassembled LACV-30. It covers

significant technical and physical characteristics and prescribes the material and guidance required to prepare, load, and

tie down the components.

5-2. Safety

Safety precautions are listed in chapter 3.

5-3. Preparation

The LACV-30 must be disassembled for transport by semitrailer. Remove and crate the propellers in prop boxes.

Remove the radar scanner unit, supports and mast. After removal of the radar mast, particular care must be taken to

seal the opening in the top of the control cabin.

NOTE

For highway shipment, the power modules are left attached to their respective rnidcraft buoyancy boxes.

Section II. TRANSPORT BY SEMITRAILERS

5-4. General

a. The LACV-30 components, loaded on semitrailers, can be transported over highways within CONUS with

restrictions. If the dimensional capacity of the semitrailers is properly utilized, some loads will exceed the 96-inch-width

and 162-inch-height restrictions of some states. When loads exceed these limits, special permits, in accordance with AR

55-162, are required. In some cases, circuitous routing may also be required. Legal limitations in oversea areas are

identified in Limits of Motor Vehicle Sizes and Weights, International Road Federation, 1023 Washington Building, WASH

DC 20005.

b. The loads illustrated in figures 5-1 through S-7 are based on the use of low-bed semitrailers with 30-foot-long

loading areas and flatbed semitrailers with 40-foot-long decks. The military M270A1, as well as a number of commercial

semitrailers, may be used to carry the larger components. Seven semitrailers (three lowbed and four flatbed) are

required to transport the disassembled LACV-30 components, including one flatbed semitrailer to transport a MILVAN

containing the anchor line box, rudders, life rafts, surf fences, tools, spare parts, POL products, and miscellaneous loose

items.

5-5. Loading

a. The components of the LACV-30 can be placed in the tiedown position on semitrailers by either a crane or a forklift

equipped with fork extensions. The crane or forklift must have a capacity of at least 4 tons.

b. Position 4-inch-thick styrofoam cushioning on the semitrailer decks so as to protect the fragile components. This

cushioning is also required between components when they are stacked.

c. Table 5-1 is the bill of materials required for blocking and tiedown of components and modules, and tables 5-2

through 5-7 provide data concerning the application of materials required for securing the loads.
