The first answer back was from Harold Chaney, of Coffing in the USA, who said: “The hoist in question is clearly an old Yale brand “Pul-Lift” cast iron lever hoist (of European manufacture, not North American), but the rubber hand grip must have been “faked” by the media agency. I don’t believe this model was ever produced with a rubber grip, and even if it was it would not have been marked “Transforming the” with the logo of the London Underground.”
Thanks for all of your responses. For next month: can you list all of the companies currently manufacturing manual hoists in Europe? (Europe here includes Scandinavia and the Balkans, but excludes Moldova, Ukraine, Belarus and Russia). Watch this space.
