A reader in the USA has sent us a photograph of an old crane that perhaps one of you can identify?
It looks as though it has some sort of unofficial superlift counterweight in place in the form of a tank trailer. Other than that we assume it is fairly original.
While it has a telescopic boom it is cable, rather than hydraulically luffed.
We understand that it is sitting in a scrap yard somewhere in Texas, although this is an assumption based on the location of our correspondent. Clearly it has not been used for some time.
