You might also get an audit and a report on the lift from professional lift consultants (just google “lift consultants” for your location). In NSW we’ve gotten quotes for auditing and then preparing a report on the lift from “AAA Lift Consultants” and “JCA Lift Consultants” who might have a Melbourne branch, or can recommend someone. The cost for an audit of our lift and a report was quoted between around $1k to $2.5k, which is reasonable, when you consider the cost of replacing a lift.
