On reviewing these replies, I think I allowed myself to be misled by Jaume Garcia's use of the phrase 'Para colgar la máquina''. I interpreted this to mean he wanted to hang up some sort of machine as I might hang up an electric hand held skill saw, a rechargeable electric drill or a small roto-tiller. I assumed he wondered what to call (in English) the hardware to be used to make it possible to mount or hang up a machine.
On a guess, Lazarus and Guillermo have addressed Juame's English phrase 'To fix the machine'? in the sense of repairing it.
I presumed he wanted to fix it to a wall or hanger. I thought of fix in the sense of fasten or attach.
If repair to the machine is what Juame has in mind, I do not disagree with Lazarua and Guillermo.
