Custom trolleys what’s involved!

We are increasingly asked to manufacture one off  aluminium trolleys to suit an existing trailer, to replace a heavy steel one.  It is really not a problem. but they  do take a lot longer to make, we cannot make stocks of components  like axles and draw bars because they are most probably the wrong size. Everything has to be made individually, the average time that an ally trolley takes from the first cut to a completely finished item is a day and a half.
