PARAGRAPH / SECTION NO:_____7.1.1_______________

TITLE: ___Lifeboat Davits Falls Replacement__________

QUESTION:

This questions was asked once before & we were given the answer “OEM, Lake Shore, can provide the details of the falls per their part numbers specificed in the davit technical manual which was provided as reference 2.1.1 of this work item”. We looked in the technical manual, as directed by the item (per reference 2.1.1, Table 2-1 Reference Data) and did not find the information that was originally requested, nor was there a part number listed. All Table 2-1 tells us is 7/8” diameter, 6x19, preformed, regular lay, prelubricated, IWRC with a mimimum breaking point and the lengths of the forward & after fall. None of this information answers our original question. Also, please note, that the OEM, Lake Shore has taken exception to providing the falls.

ORIGINAL QUESTION

The note in this paragraph recommends purchasing the falls pre-assembled with spelter socket. Is the socket open or closed? One end or both ends of the falls?

ANSWER:

Reference 2.1.1 of the work item states “2-2.4 BOAT FALLS. The boat falls are made up of 7/8 inch diamter, (6x19), preformed, regular lay, pre-lubricated, I.W. R.C. wire rope with a breaking strength of 69,200 pounds. An 1-1/4 inch by 12 inch turnbuckle with a closed spelter socket is attached to the inboard end of the trackway for taking up slack. The forward fall is 265 feet long and the aft fall is 300 feet long.”
