<p>Hi All,</p>
<p>With regards to the matter of the mechanical means of
articulating the detector on the assembly structure pivot, a
decision of the method will be determined by a collaboration of
the INFN group, Hall B (Bob Miller), and Facilities Management
(Rusty Sprouse and Suresh Chandra). The DSG will wait for specific
details containing the specific lifting method.</p>
<p>As for the TOSP, I will modify the current documents to reflect
input from the aforementioned groups. DSG will also consult with
INFN about changes to the procedure.<br>
</p>
<p>Thanks<br>

Using the gantry to "lift" the RICH will also apply a lifting
force to the pivot axle. The higher the back of the detector is
raised, the higher the stress on the RICH attempting to pull the
assembly structure out of the floor. This force could damage the
detector.<br>
<br>
A better plan would be to use a lever hoist located at the current
wire rope sheave location. This would eliminate the stress on the
detector.<br>
<br>
The wire rope sheave supplied is only rated to 1000kg. This sheave
is too small for a 1000kg winch lifting a 1000kg detector. <br>

<p>Rusty,</p>
<p>Under the current arrangement of lifting, the load
in the winch cable keeps on reducing as the detector
is lifted. Bob Miller told me that their group have
a gantry crane available in the area. In absence of
availability of calculations, we may resort to the
following:</p>
<p>1) We hook up the detector to be lifted both to
the winch cable & to the gantry crane. For a
good portion of the lift the gantry crane will
remain effective to take the load. After that the
load reduces considerably and the winch cable can
take over the load.</p>
<p>2) The above method can be safely used without
performing any load test.</p>

<p>Rusty,</p>
<p>I have looked thru the documents. I have also
talked to Bob Miller. Summary is as follows:</p>
<p>1) In calculations, they have reported weight of
detector as 1000 Kg. Their calculations show the
load for the winch of 875 Kg, which is O.K.</p>
<p>2) The working load for the winch given in the
Winch manufacturer's papers is 1000 Kg. Thus
winch is O.K.</p>
<p>3) There are no calculations or details of frame
members provided. Hence the frame cannot be
checked.</p>
<p>4) Bob Miller told me that he has asked the
persons in Italy to provide calculations on the
frame.</p>
<p>5) If calculations become available we will
check them. If not we will resort to other
solution/s.</p>

load test the RICH assembly
structure. Do you</span><br>
<span style="color: rgb(0, 0,
255);" data-mce-style="color:
#0000ff;">have a plan or any
tooling for how to load test
this structure? It</span><br>
<span style="color: rgb(0, 0,

#0000ff;">looks like we would
need some kind of tool to take
the place of the</span><br>
<span style="color: rgb(0, 0,

load to the structure.</span><br>

rotation of RICH after the

Rusty Sprouse has not approved
the load test at</span><br>
<span style="color: rgb(51, 51,

<br>
<span style="color: rgb(51, 51,

calculated that the maximum load
exerted on the</span><br>

adequate for the rotation of
