[Dsg-rich] Fwd: Riich Module Lifting & Stiffening Tool

[Dario Orecchini]

Good morning Mr. Kreyling,
I'm Dario Orecchini, one of the INFN technicians that have in charge the
realization of the lifting tool,
and I try to give you a first answers to your questions.

1) regarding the standard of the material to use, are surely acceptable the
proposed standard....
                     - Square tube, from 80mm to 3inch (76,22mm) - wall,
from 4mm to 3/16" (4,7mm)
                     - Thick plate, from 10 mm to 3/8" (9,5mm)
                     - Thick plate, from 8 mm to 5/16" (7,9mm)
    The square tube named "Part.1" has been foreseen 100mm with 5mm wall,
if you agree, you can adopt:
                     - Square tube, from 100mm to 4 inch (101,6mm) - wall
0,188" (4,77mm)

 2) Painting... you can adobt the standard in use in the US. Typically in
Italy these kind of tools are painted yellow
     with the indication of the "Maximum Load".

3) Welding... you can adobt the certifications foreseen in US.

4) Tolerance... I confirm you the Class C tolerances (normally used for
carpentery).
     Nevertheless, some distances between holes and some geometrical
aspects must be kept under control.

5) I'll try to send you the step file of the lifting tool coupled with the
component to lift.

However, a your visit in JLab would be really useful, to clarify all the
aspects to deepen.
Obviously, the details of the visit must be definited with the JLab
Detector Support Group (DSG).

Regards
Dario Orecchini
