... every piece on it and the trolley itself is serviced by a different manufacturer.
And you can bet your life that if something "happens", each will be blaming the other!
Don't you have a servicing capability in-house then, Ian (or are you referring here to a warranty situation)?
If not, it sounds like you may like to consider an independent service provider.
PS: I am reminded of the Happy Days when manufacturers such as Vickers made (and were proud to support) the whole thing! So much for so-called "progress".
