NWP 4-01.43. Draw the net up around the load and lay the cornersof the net loosely on top of the load.4. Secure the rings with a becket.5. To move the pallet by forklift, carefully insertthe forks through the net’s webbing and hoistthe pallet.WARNINGNever place a netted load upon anotherpallet for movement by forklift. When thehelicopter lifts the load, the loose pallet maybecome a missile hazard because of rotorwash. The pallet within the net is adequatefor moving the load by forklift.NoteAn alternate (and sometimes preferred)method of moving a netted pallet is to usethe forks as an overhead lifting device withthe use of a Mk 91 Mod 0 adapter hook (seeFigure 10-4).10.6.5 Missile Dolly Loading. See NAVSEA OP3192 or OP 3206 procedures for preparing bare missilesand loading them into the Mk 6 missile transferdolly for VERTREP.10.7 WEIGHT AND IDENTIFICATION OFLOADSAs each load is made up, mark the load with itsweight in pounds (e.g., 500 LB) and any identificationrequired by the customer. The method of marking dependson the procedure of the individual delivery ship.Use chalk, a felt-tipped pen, or a tag. Tags may becolor-coded for easier identification. Marking of loadsfacilitates pairing of loads — the combining of lightloads to provide the most efficient weight for helicopterlifting. Select the desired combination of loads thatachieves the desired weight for each lift.As many as four pallets may be carried per lift,depending on the size of the drop area, the ability ofthe receiving ship to clear the drop zone, and thefuel load of the helicopter. The average weight of asingle or combined load (using an H-46 helicopter)is 3,000 lb (1,360 kg). Heavier loads may be carriedunder ideal weather and atmospheric conditions,depending on the helicopter’s fuel load, andwhen cleared by the helicopter pilot. However, heavyVERTREP lifts must not exceed the safe working loadof the hoisting sling.CAUTIONPaired loads should be approximately thesame configuration to reduce the possibilityof tipping the load on pickup or drop.NoteVERTREP loads shall be color-coded whentransfers are conducted under EMCONconditions.10.8 ATTACHING SLINGS TO LOADS10.8.1 Adjustable Pallet Slings. Palletized ordnancemay be transferred without cargo nets using theadjustable pallet sling (Figure 10-14).1. Select the proper sling according to the height ofthe load (see paragraph 10.5.5).2. Pass each loop of the sling under the overhangmade by the upper boards on the sides of the pallet.3. Pass each basket leg of the sling under the wingson each side of the pallet.4. Pull the ends of the sling legs containing theswage stops through the sling tensioners untilthe bridle is tight across the top of the load andslack is out of the sling.5. Adjust the sling so that the lifting thimbles arecentered and at an equal height up from the pallet.6. Engage each tensioner over the nearest swagestop, lower the latch to the stirrup, and lockthe tensioner.CAUTIONThe last swage stop on each sling leg is asafety bead and shall never be used.10.8.2 Safety Hook Operation. The safety hookis the only working part of the hoisting sling. An explanationof its operation is needed before any descriptionsof attaching hoisting slings are covered. SeeFigure 10-15.10-16 ORIGINAL
