CHAPTER 6

MARINE AND TERMINAL TRANSPORTABILITY GUIDANCE

6-1. Scope

This chapter provides transportability guidance for movement of the operational LACV-30 by oceangoing vessel. It

prescribes the materials and guidance required to lift, tiedown, and discharge the LACV-30.

6-2. Safety

a. Remove all cargo before lifting the assembled LACV-30.

b. Secure all loose equipment before lifting.

c. Lift only by the four hoist fittings,.

d. Lift only in a level attitude.

e. Lift slowly out of water.

6-3. Marine Transportability

The LACV-30 is marine transportable under its own power -and as deck cargo on oceangoing break-bulk ships having

sufficient clear hatch cover or deck area. It is transportable on the open deck of containerships by the use of specialized

shoring, blocking and bracing, or false decking. It is also transportable aboard SEABEE vessels.

6-4. Lifting

Correct lifting points on the LACV-30 are the four craft-lift fittings located at deck stations 348 and 585 on the

inner splice plate lines. The two craft-lift slings are attached to the hoist fittings by four adapters. The craft-lift slings and

the adapters are part of the LACV-30 equipment.

WARNING

Insure that the LACV-30 gross weight is less than80,000 pounds (36,288 kg)

WARNING

The four hoist fittings are the only fittings that may be used to hoist the LACV-30.

A lifting diagram is shown in figure 6-1. The LACV-30 must be maintained in the level position during lift. The

craft hoisting sling is designed to accomplish this by the use of an adjustable bail. Refer to the contractor's maintenance

manual (app) before lifting. The LACV-30 can be lifted by cranes of at least 40-ton capacity.

CAUTION

When a LACV-30 is being lifted out of water, the initial lifting must be done very slowly so that water trapped in the

flexible trunk has time to drain out. The correct lifting speed is indicated by the level attitude of the craft. A tendency to

hang stern low is an indication that the LACV-30 is being raised too fast. The weight of the water trapped in the trunks is

considerable and lifting too fast could result in structural failure.

6-5. Loading

a. Figure 6-2 shows typical tiedown details of a LACV-30 loaded on the open deck of a break-bulk ship. The LACV-

30 is oriented athwartship across the hatch, with the forward landing pads resting on the port hatch cover and the aft

landing pads resting on the starboard hatch cover. Tables 6-1 and 6-2 lists materials required for tiedown and their

application. Tiedown materials must be furnished by the shipper.
