<p style="margin: 0px;">Hello
Bob,</p>
<p style="margin: 0px;"><br>
</p>
<p style="margin: 0px;">Please
find attached slides from Marco Mirazita showing
calculations for the planned rotation of RICH after the
assembly of the detector shell. </p>
<p style="margin: 0px;"><br>
</p>
<p style="margin: 0px;">The
GR1000 winch (image of load specifications also attached),
is rated for 1000 kg. Rusty Sprouse has not approved the
load test at 1,250 kg due to the 1000 kg rating of the
GR1000 winch.</p>
<p style="margin: 0px;"><br>
</p>
<p style="margin: 0px;">However,
it has been calculated that the maximum load exerted on the
winch will be ~775 kg. Please let us know whether the rating
of the GR1000 winch is adequate for the rotation of RICH
using the lift procedure as shown in the slides. If it is
not, we will find another solution.</p>
<p style="margin: 0px;"><br>

<p style="margin: 0px;">Best
regards,</p>
<p style="margin: 0px;">Tyler<br>
