Thank you for your reply Big Burner.
Maybe I should have described the machine as a Lorry Loader (the type that loads trains with coal and lorries with salt etc)
I may have the chance to join a company with this type of machine,and the boss told me that I would not need a licence to operate it.
I would obviously require some sort of training by a competant person before I could operate it.
Would this then require me to be issued with some form of competancy certificate?
