1960s U.S. NAVY FILM CVA-59 FORRESTAL-CLASS AIRCRAFT CARRIER RESUPPLY & MATERIALS HANDLING 11915

[Music] to support and operate aircraft to engage in attacks on targets a flat and aore to engage in sustained operations in support of other forces is the mission of our aircraft carrier to keep our fleets mobile nearly all replenishments of provisions and supplies are carried out of sea [Music] while preparing for and during these replenishments and until stores are struck below flight operations cannot be conducted the old Materials Handling system preparations for replenishment must start long before the AF comes alongside about 2,000 ft of gravity conveyors have to be spread out on Deck strike down points are rigged for replenishment the Navy is continually evaluating and improving Materials Handling equipment to cut down replenishment time this is a report on recent research and development efforts by the Bureau of supplies and accounts and the Bureau of ships working as a team to improve the Materials Handling capabilities of CBA 59 class carriers this study and resulting improvements were made in the Saratoga previous studies made by Banda have resulted in modernized Materials Handling in the reaper ships like the one shown here and speeded up breakup the new AF equipment has speeded up transfer rates this makes fast handling on receiving ships even even more important nylon cargo Nets developed by the Navy research facility are lightweight and capable of handling heavy loads deck Edge elevators on the carrier are used as net Landing areas Nets must be unloaded quickly to keep the landing areas clear under the old Materials Handling system stores have to be placed on conveyors without sorting this later creates major segregation problems that hold up strike down hundreds of men are required to keep stores moving on the hanger deck multiple handling along the roller conveyors breaks open the cases and rips the bagged Goods the complicated system requires overpasses for for and a and a th ship movement of stores under the old system most of the provisions must be first struck down to the mes decks where they are stacked and later segregated the Saratoga had three stores on elevators they extended only from the second deck to store room levels boxes had to be loaded one by one and offloaded the same way using all three elevators only a few tons per hour could be struck below many handlings were required to strike down to lower decks below deck areas soon became clogged with stores as this happened stores began to back up in all areas slowing strike down stores built up away from strike down points and had to be rehandled many times many hours after the replenishment from the reaper stores were still being segregated and struck below from the mes deck these are all also bomb assembly areas they must be cleared before bombs can be handled and planes rearmed these then are the problems that confronted the Materials Handling engineers in the CBA 59 class carriers lack of store segregation at the receiving area resulting in later multiple handling excessive Manpower excessive damage lack of direct access to store rooms to illustrate the new Materials Handling methods let's go aboard the Saratoga where the new system is installed records are checked and requisition submitted long before replenishment day the big carriers consume more than 20,000 lbs of Provisions per day now with the new Materials Handling system flight operations can be conducted right up to the time replenishment is to begin the two after stores elevators have been ripped out and replaced with vertical tray lifts extending directly from the hanger deck to all store room levels under the old system using gravity conveyors on the hanger deck transfer from the AF had to be split up it was necessary to transfer Provisions for store rooms located forward in the carrier before that for stor rooms located at was sent across this made extra work in the AF and made it difficult to balance the tonnage between transfer rigs now gravity conveyors are no longer required on the hanger deck saving many hours of rigging pallets are laid out in Board of the elevators these are tubular nestable pallets developed by the naval Supply research and development facility with pallets laid out net loads can be segregated as they are received forklift trucks pick up the loaded pallets and take them directly to strike down points all strike down points can be worked simultaneously a ton at a time is moved with no damage to the provisions pallets can be spotted alongside strike down points now strike down can be made directly from the hanger deck to stor rooms these tray lifts are simple to install and require very little space they were designed with a capacity to handle all sizes of provision boxes and bags the lifts serve all levels to offload at any level a simple unloader is placed in position now only a few men are required at the strike down station gravity conveyors take the provisions from the tray lifts to the store rooms an intercom is provided in the tray lifts to control strike down so if a bottleneck develops at one level level it is a simple matter to shift unloading to another each of the can strike down 45 tons per hour forward tray lift comes up only to second deck it is fed through a bomb elevator coming down from the main deck plans now are to extend the lift up to the main deck for easier access every means of strike down are still used now with segregation upon receipt and tray lifts handling most of the cargo other strike down points operate smoothly new convertible ladders designed by the research facility save time in rigging for replenishment they were installed at strategic places in the Saratoga the tubular pallets are nestable and take up very little space for story Wheels can be quickly attached without tools the nestable pallet then becomes a live dolly for handling stores fresh Provisions are sometimes received from foreign sources in open boxes even these can be struck below with the vertical tray lifts without damage lightweight aluminum four-wheel dollies being used here to transport the fresh Provisions have a capacity of 4,000 lb before the tray lifts were installed large working parties were required for daily breakouts now only a few men are required and Provisions can be broken out immediately before meals this then is the new Materials Handling system transfer can start with very little preparation in the carage early segregation of stores onto pallets movement of large quantities at one time eliminating roller conveyors and damage fewer men in working parties the tremendous Savings in time using the new Materials Handling system time to strike the stores below has been reduced by more than 50% as a result of this study the Bureau of ships plans to install the new system in all the 59 class carriers as research and development efforts continue replenishment time will be cut even more so our carriers will be combat [Music] ready
