MOUNTING PIVOTS NORMAL LOCKED POSITION LOCK EXTENDED POSITION PIVOT DES FE Workshop at FNAL December 14-15, 2005 Vaidas Simaitis, University of Illinois at Urbana-Champaign
Why PIVOTS ? • Allow some FLEXIBILITY to avoid possible obstructions, for extraction or insertion of front modules or transition cards. • PIVOTS allow either end to be angled out, and are locked in position for SAFE access. • Little extra $$ for a lot of SAFETY! • Final design is on hold until mounting method and position is OK’ed by FNAL DES FE Workshop at FNAL December 14-15, 2005 Vaidas Simaitis, University of Illinois at Urbana-Champaign

DESIGN DETAILS • Our design resides in much detail at our UIUC website at CLICK HERE or copy and paste: • web.hep.uiuc.edu/Engin/DES/DHE_10_Crate/DHE_10_Crate.html • The best way to see the design is to download the free DWF Viewer. • You can then rotate, zoom in/out, hide parts in assemblies so you can see the insides, and print any view you like. • Else, you’re stuck with the 2D PDF views.
