I'm planning on building a Meccano model of a steam crane and I was wondering how the drive was reversed. Was the engine run in reverse, like a railway locomotive? Or did the engine always run in the same direction, like a diesel engine, and reverse gear was selected?
I know the answer might seem obvious, but agricultural portable steam engines had fixed valve gear and only ran in one direction. If it was required to reverse the drive to the machine, the belt would be crossed.
As cranes have got gears and selectors to engage the various functions anyway, I wondered if they maybe had one more selector and no reversing valve gear.

Graham,all the Breakdown Cranes I drove had reversers like steam engines,the Cowans cranes worked in full gear both ways where the Ransomes could be notched up like a steam engine,this was ideal when raising the jib from flat it saved steam and water.hope this is of help ,P.Woad
