NWP 4-01.45. Position the return load under the highline.6. Signal the delivery station to send over the trolley.(5) DELIVERY SHIP1. Lower the CDR hook to a point where the cargohandlers at the receiving station will be able toreach it.2. Raise the transfer head, and send over the trolleyand CDR.(6) RECEIVING SHIP1. Attach the sling on the return load to the CDRhook (Figure 6-35).2. Attach the quick-release hook on the threefold tothe shackle on the CDR hook.3. Pull on the brake release lanyard to take slackout of the CDR’s cable.(7) DELIVERY SHIPLower the transfer head to the full-down position.(8) RECEIVING SHIP1. Load is ready to be raised. Station a sufficientnumber of line handlers on the hauling line ofthe threefold.NoteThe number of line handlers required to liftthe load will depend on the weight of theload. A Mk 6 dolly with missile, forexample, requires 12 to 15 line handlers forlifting. The threefold can be used to raiseloads that weigh up to the capacity of theCDR (5,700 lb (2,584 kg)).2. Pull the brake release lanyard on the CDR.3. Line handlers haul in on the hauling line.NoteThe threefold, attached to the CDR hook,will carry the weight of the load. The CDRwill not sense weight and will reel in theCDR hook.4. When the load is high enough to clear the deckedge (about 2 feet (60 cm) in most cases), releasethe lanyard to set the brake.5. Slack off on the hauling line.NoteThe CDR now holds the load.6. Pull the tripping lanyard on the quick-release hookto disengage the threefold from the CDR hook.7. Secure the threefold block out of the way.8. Signal the delivery station to retrieve the load.(9) DELIVERY SHIP1. On signal from the receiving station, raise the transferhead to the full-up position. This provides moreclearance under the load (at the receiving station).2. Haul in slowly until the load clears the receivingstation’s deck edge, then retrieve the load.6.16 TENSION/DETENSION OF STREAM RIGNoteSTREAM with STAR rig will not be usedfor tension/detension.The third method of lowering and raising the load atthe receiving station is tension/detension. This methodcan be used for delivery or return of loads when the followingare taken into consideration:1. Use the CDR to deliver a load, if a CDR is availableand the load to be transferred is within itscapacity (5,700 lb (2,584 kg)).2. If the CDR is attached to the trolley and the load to bereturned exceeds 150 lb (68 kg) (the maximum weightthat the CDR’s spring motor will pick up), use either themethod of heavy load return described in paragraph6.15.7 or the rig configuration with tensioned outhauldescribed in paragraph 6.16.1. This tension/detensionmethod is normally used for load return only.NoteLoads weighing from 5,700 lb to 10,000 lb (2,584to 4,536 kg) may be transferred by one of theheavy-lift methods described in paragraph 6.17.6-55 ORIGINAL
