Marco, 



Good afternoon, my name is Michael Kreyling and I am currently working on a quote for the Rich Module Stiffening Tool. I have a few questions before I move forward. 



1) The material listed is all metric, which is harder to get and cost around three times as much. We can save money and time going with standard 



Suggestion: 

80 mm Tube with 4 mm wall = 3 inch square tube with a 3/16” wall 

10 mm Thick plate = 3/8” Thick Plate 

8 mm Thick Plate = 5/16” Thick Plate 



2) What color are we going to paint it? I know the bolting surface is to be free of paint, but will we prime the bolting surface? 



3) I see you require a weld inspection, what if any certifications do our welders need? 



4) Since this is a lifting tool do we need to get a weight test to certify the lifting capacity? 



5) The tolerance calls out ISO 2768-mk-e, just wanted to confirm we will use the class C (coarse) tolerances. 



6) Is there assembly drawing with the item you are lifting, so we can see how this part will be used? If not would it be possible to come to the site to see where it will be used. Mainly we need to know if the distance between the holes located on the back bar correlate with the holes in the angle bar connection. I included a picture, to help explain it clearer. 



I’ve studied the drawings, once you answer these questions I’m sure I can put something together for you. 





Thank You,
