Tom,

I renamed the .zip file to have a .safe extension otherwise I don't think it will be sent.

Tom,

Attached are some files giving the traces of the lasers for assembly from the right (+Y) and the left (-Y). The files ending in 10r are for the right side, those ending in 10l are for the left side. The spreadsheets give the xyz data of the laser traces and plots of them. They also give plots of the "Strap Lengths" on the second worksheet for a fixed hook height. I used a height of 160 for the left side, but reduced it to 134 for the right side to minimize the total variation in length required. The powerpoint file contains a plot of the left and right sides overlaid. It looks like we can limit the required motion to ~26.2 inches with this scenario. This assumes the hook height is fixed during assembly at it's initial height. If you allow the hook to change in elevation during assembly the required motion is further reduced to ~18.1 inches.

There are a bunch of ibl files as well. Files labeled trace01 thru trace03 are the laser traces, trace04 is the CG and trace05 thru trace07 are the swivel points. Hopefully you can do a sanity check on these in ProE.

Regards,

Art

Art - attached it updated data on the laser and crane geometry.  There is some slight difference in the laser point data.  I'll stop down.
