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>

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