Until July last year these three cranes graced the Clyde shore at the Inchgreen Dry Dock between Port Glasgow and Greenock. Two were luffing cranes.
They were a wonderful part of the local skyline, and a constant reminder of the Clyde's great days as busy port and shipbuilding centre. I miss seeing them.
There are some fabulous pictures and lots of technical information about the Inchgreen Graving Dock here. It was built in the 1960s as a response to the increasing size of ships being built.
One crane still had its maker's plate - William Arrol & Co.
There are various films online showing their demolition - I haven't been able to watch them.
