#55539, "Winches in reciprocating engine room (starting platform level)"
This is partly a response to Steve Fury's recent 3D engine room renderings, but I'm posting it as a new topic so as not to derail his thread. The engine room winches at the starting platform level have never been discussed in any detail, to my knowledge. Here is what I know about them:
> A photo printed on page 401 of 'Titanic, the Ship Magnificent' volume 1 (originally from the journal 'The Electrician'). It shows a cluster of telephones on one of the central support columns and, most interestingly, a winch immediately behind the column. From the position of the watertight door in the background this seems to be the aft-most column in Olympic's reciprocating engine room.
> The Olympic Drawing Office book, often referred to as the 'Andrews Notebook', lists two 2-ton electric winches in the reciprocating engine room.
> Two 4-horsepower electric winches are listed in Olympic's 1935 auction catalogue.
> The 'Shipbuilder' special number mentions electric winches in the engine room in connection with the lifting gear, supplied by Chambers, Scott & Co.
Beyond the single photo and the rather sparse written sources there's little else to go on. They do not appear on any of the detailed plans printed in 'The Shipbuilder', 'Engineering' and other journals. I've attached a drawing here showing possible locations for them. The aft winch position can be roughly estimated from the 'Electrician' photo, but the forward one is only a guess. I've copied the basic size and shape from the boat winches, though this will probably turn out to be incorrect.
Does anyone else have further information on these winches, or similar winches on other ships? As far as I'm aware there's nothing visible on the Titanic wreck.

Hi Ralph. When I looked at Steve's ER floor views the openness bothered me, you've answered what's missing. Your answer looks good, you've covered more than I've seen. I bet the winches earned their keep during the erection stage.

This entire thing is "news" to me. I've never seen any indication of winches installed at the starting platform level of either engine room -- just the overhead traveling lifting hoists which were operated with both a chain wheel and an electric motor. I have seen one or two drawings which show what are identifiable as more pumps located between the engines than those shown in the greatly simplified "Shipbuilder" plan. I'm NOT suggesting in any way that I believe that there CANNOT be winches in these locations -- only that in the four decades that I have been studying the machinery of these ships, I have never seen a drawing or a written description indicating winches of this type in the locations shown here on board Titanic, or on board Olympic as completed. As always, I look forward to seeing anything new that has come to light regarding the machinery spaces!
