The capacity of any machine is supplied by the manufacturer not the service technician. In the UK most manufacturers have stopped fitting multi weight SWL plates. I believe this is to prevent confusion over the actual SWL and prevent operators lifting an overweight load past its safe height (if you can get a plate for this machine how do you prevent the operators going past the safe height?). Your customer should contact his supplier and see if a multi weight plate is available. If someone posted a multi wieght chart on this site which said what you wanted it to say, could you or would you be prepared to use it?
