1970 Dennis Maxim with Holmes Recovery Crane1970 Dennis Maxim with Holmes Recovery Crane
Pat R-B in response to an earlier photograph of this machine, mentions the twin booms of the Holmes recovery crane. Here we can see the crane in more detail. The side doors in the body by the main vertical support pillars open outwards so that support legs may be deployed at angles of 30 degrees or more to assist with stability when winching from the side.
The Holmes crane was (is) very popular in the States where it was widely used for general recovery work. When I needed spare parts for it 'Zips Trucks' had them delivered withn a week.

Big cranes - 40 or 50 tons, or more - are very common in German fire departments, and are also to found in some stations in Scandinavia, Poland, the Czech Republic and the Netherlands.
But in the rest of the world, it seems fire services do not have any need for them.
