I need to get some simple tools for our elevator maintenance stuff, we aren't an elevator company but we have 24 elevators in our company and we do perform the inspection & routine maintenance by ourselves, therefore I need the following simple tools but I don't know where to get them from:
-Tool for measuring ropes wear.
-Tool for measuring ropes tension.
-Tool for measuring the pulleys condition & the pulley grooves. (I don't know how should it look like"

Do anyone found the magnetic flux instrument which used for ropes inspection useful?

Many thanks.
