Full text of “Army Helicopter Internal Load Operations”
This chapter identifies the Army helicopters used for carrying internal loads. Roller, conveyor, 8-foot, NSN Determine the amount of tie-down devices required to properly secure a composite load of 1, pounds. Ground personnel who inadvertently encounter high velocity rotor wash should drop to a sitting or prone position to keep from being injured.
Shoring is using lumber to spread the weight of highly concentratedloads over a greater area of the cargo floor than that covered by the cargo alone. When the litters are installed, there is still room for 15 seats down the middle for ambulatory patients, attendants, 55-40-2 troops. Once you determine how each item will be loaded, requisition a consolidated list of the number ofpallets and cargo nets through supply.
As you secure the cargo on the pallet, make sure that you do not exceed the dimension and weight limitations for the designated aircraft. They must be included in the total weight of the vehicle. This acts as a buffer between the cable and 5-450-2 floor.
The floor provides the downward restraint.

This publication gives the dimensions and weight of almost every item the military has. It also describes the capacities, capabilities, and limitations of these helicopters. Determine the amount of forward and lateral restraint. In the vehicular tread area, the maximum allowable floor loading is 1, psf.
Army Helicopter Internal Load Operations (FM 55-450-2)
To obtain the maximum pod wheel ground clearance of 18 inches when the pod is attached to the helicopter, full retraction of the pod wheels is possible. The binder consists of the two body plates that attach atone end to a short hook and at 55-4500-2 end f, a handle that holds a pivoting long hook.
Litter patients including litter, splints, and so forth: The structure limits of the flooring for a particular aircraft are found fk the aircraft operator’s manual. If night resupply is scheduled, a larger area is normally needed. When tie-dow n devices are passed over cargo from side to side [Figure Detail C]the tie-down device should be as close to yu degrees as the floor fittings will permit. Married L Pallet Assignment. Tie-down fittings on the side of the beams are good for 1, pounds maximum per fitting perpendicular to the beams.
The receiving unit — 1 Selects and controls the LZ. The most important part of the mission is prior planning.
Load spreaders shoring are support placed beneath an object to increase floor bearing ar pa to prpypn t excessive concentration of weight. That is, for forward restraint, the tie-down devices at the forward end should have a greater length than those used toward the aft end. Palletize cargo from the heaviest to the lightest.
When operating the helicopter at a critical gross weights, use the exact weight of each occupant plus equipment. The height of a composite load should not be greater than itsTength in the longitudinal direction, if it can be avoided. Enter the information obtained in Steps 1 and 2 into the formula. Sign In Sign Out. Barrier nets for forward or aft restraint should be increased in length in the direction of the load. Figure shows the tie-down rings, and Figure shows the UH-1 cargo compartment 5-5450-2.
When attach- ing the L-shaped hook end of the chain to a cargo tie-down provision, remember that the hook must be properly engaged with a chain link. The correct method is to pass the hook end over and brine it up under the tie-down point.
Use tetrachloroethylene only in areas where substantial 55-450- is available. The relationship between border width and shoring thickness applies to all shoring. FMPathfinder Operations, 9 October Include shoring weight with the cargo weight to accurately determine cargo CG.
This final result inches is the CB of the vehicle measured from the front end reference datum line. Pass the link end of the second chain through or around the left attach- ment point. The spacers are used to keep the pallets aligned and properly spaced so that they will lock into the f rail systems.
The MCC will coordinate and arrange for aerial support.
