7. Cold detector vessel support points on the bottom while moving it into the buildingmm
We have been told the vessel must ride on the 6 central support pads while
moving into the building. As an alternative, can it be supported as
presented in the following strawman plan?
I & I Team | March 11, 2016

8. Vertical space for the lifting fixture
Crane hook height above the loading dock floor = 6700 mm (slide 5)
Cold detector vessel vertical height = 4260 mm (slide 6)
Height of the 10 spherical supports = 180 mm per Claudio.
7” height allowance for rollers and 1” (25.4 mm) thick floor tracks or plate = 8” (203.2 mm) (slightly arbitrary)
Extra height allowance to install the 10 spherical supports = 5” (127 mm) (arbitrary)
Clearance between top of rail/plate and the underside of the cold detector vessel = – = mm (12”). This means we have a vertical gap of mm between top of rail/plate and the underside of the cold detector vessel to install the spherical supports.
Vertical space for the lifting fixture inside the building = 6700 – ( ) = 6700 – = mm = 83” = 6’ – 11”.
On slide 6 we have mm overhead clearance between the top of the cold detector vessel and the lower edge of the building access opening that is above the cold detector vessel.
< mm. So, we have more headroom in the building than the building access opening provides.
I & I Team | March 11, 2016

9. Vertical space for the lifting fixture
This means:
(1) If we have one lifting fixture, we need to cut the building opening higher so we can lift the cold detector vessel with the building cranes and the lifting fixture when part of the vessel is outside the building. The opening must be cut – = 681 mm (~27”) higher. Say at least 30” higher.
(2) If instead of having a single lifting fixture to lift the cold detector vessel we have two, one for each crane, then we will be able to slightly lift the load off the rollers when the vessel is only partly inside the building and the building opening does not have to be cut higher.
Note: Height of the lifting fixture should be as short as possible.
Note: The 10 spherical supports are bolted to the bottom of the cold detector vessel inside the building.
Note: We need an adapter plate between the support pad and the rollers to gain the 127 mm extra height and to match the bolt patterns. The adapter plates on the last pair of rollers must be designed to allow for slight rotation when the crane picks up the far end of the cold detector vessel a little. See slide 16.

10. Will the rollers miss the building floor passageway?
Width of the building access opening at the floor passageway = 3733 mm (slide 4).
Centerline spacing for the 10 support pads on the cold detector building = 127-3/8” = 3236 mm (slide 7)
Dimension from the center of the 10 support pads to the outside wall surface of the vessel = 365 mm. (calculated from dimensions on slide 7)
Minimum capacity of each roller is 30 US short tons because towards the end of bringing the cold detector vessel into the building, one building crane has half the vessel weight and two rollers carry the other half. The rolling element width is 4” (101.6 mm) maximum. Use 105 mm.
Clearance between the cold detector vessel and the building column on the tight side of the opening (that is, on the opposite side of the floor passageway) = 25.4 mm (1”) (arbitrary)
Required floor width for the roller elements = ∑ = / = ~3680 mm.
Dimension between the ends of the roller elements and the edge of the floor passageway is 3733 – 3680 = 53 mm clearance. We will check to see if this edge distance is ok.

11. Installation with 2 building cranes
Comments on the procedure:
Cribbing must be placed locally under the cold detector vessel when workers install and remove rollers, or when installing the spherical supports. Use of adequate positive cribbing will allow workers to reach under the vessel.
Bolts to install the spherical support feet must be accessible from the side of the vessel.
Methods we are considering to push on the cold detector vessel when it is on rollers, in order of preference:
Fermilab fork trucks (slide 33)
Hydraulic cylinders anchored to the rails
Electric Johnson bars
The pushing force is estimated to be 6,000 Lbs (27 kN) with the cold detector vessel moving on rollers.
The fork truck stays outside the Far Detector Building.
I & I Team | March 11, 2016

12. Installation with 2 building cranes
The starting point is outside the building on the hardstand: The cold detector vessel has been lifted off the trailer and placed on rollers (or air pads) so it can be pushed into the building. The rollers run either on rails or plate that has been placed on the hardstand.
In the following slides: (1) Green circles represent the rollers. (2) Red asterisks represent the spherical supports. (3) The ½, 1/3, and ¼ points for the cold detector vessel are indicated.
As noted on slide 7, the rollers need only be installed on the 6 central support pads of the cold detector vessel. The ends of the vessel do not need to be supported when pushing it on rollers.
It is assumed we have two lifting fixtures, one for each crane. The cranes will attach to the lifting fixture at the ¼ points of the cold detector vessel after the vessel is far enough inside the building. The lifting fixtures are placed inside the building before the vessel starts to be pushed in.
We push on the cold detector vessel to move it into the building as indicated by the green arrows.
All of these points are illustrated on the next slide.

16. Position 2
The first pair of rollers are 46” (1168 mm) from the edge of the loading dock.
Move the other crane into position.
At this point we lift the vessel slightly with the one crane and remove the first and second pair of rollers from the support pads and install spherical supports. The reason we remove these four rollers at this point is because the load will transfer back to the rear pair of rollers when the crane lifts the vessel, thus unloading the first and second pair of rollers. The adapter plates on the rear pair of rollers must allow for vessel rotation when the crane lifts the far end of the vessel. Note: When the crane lifts one end of the cold detector vessel, we can use the fork truck to lift the other end rather than tilting the vessel by lifting one end with a crane, if the vessel is approved for lifting at one end with a crane and with a fork truck at the other end; see slide 34.
The vessel weight is now carried by one crane and two rollers.
Continue pushing on the vessel with 2 rollers and moving the crane to keep moving the vessel in the building.
All of these points are illustrated on the next two slides.

19. Position 3 The last ¼ point is under the second crane hook.
The lifting fixture dimensions are illustrated with the green squares. If the second crane picks up the other half of the vessel at this location then the fixture dimensions are roughly 4 by 4.5 meters.
At this point we lift the vessel slightly with the second crane and remove the last pair of rollers from the support pads and install the spherical supports in their place.
The vessel weight is now carried by the two building cranes.
The vessel is now moved using the building cranes.
The last two spherical supports need to be installed.
All of these points are illustrated on the next two slides.

28. Space for the mobile crane through the building wall
Width = 3733 mm = 147” = 12’ – 3” (slides 3 and 28) limited by the floor passageway.
Maximum opening width = 5943 mm = 234” = 19’ – 6” (slides 3 and 28).
Vertical = 6019 mm = 237” = 19’ – 9” (slides 3 and 28) without cutting the opening in the building wall higher.
Note: Tolerance on the dimensions on slides 3 and 28 is +/- 1”. Minimum dimensions are shown above in the first 3 points of this slide.
Maximum vertical opening height = TBD mm = ” = ’ – ” by cutting the opening in the building wall higher.

I & I Team | March 11, 2016

31. Fermilab mobile crane
(11’-3.69”)2 = 22’ – 7.38” > 19’ – 6”. The Fermilab mobile crane cannot enter the building. It would have to sit outside and boom into the building. It doesn’t look like there is enough space to deploy the outriggers on the hardstand.
I & I Team | March 11, 2016

32. Fermilab mobile crane
A mobile crane must have enough capacity to lift 30 US short tons.
Fermilab mobile crane capacity when parked outside the building with a boom length of 81’ and a load radius of 65’ to lower the cold detector vessel into the warm vessel < 6 tons → Does not work. Note: I did not check to see if the boom angle works inside the building.
Conclusion: The Fermilab mobile crane cannot be used to bring the cold detector vessel into the building nor install it in the warm vessel.

34. Questions for Claudio and Marzio
Will the cold vessel be shipped with the spherical supports bolted to it?
Where are the push points on the end of the cold detector vessel? We will apply force to the push points to move the vessel into the building (when it is on rollers).
Can we lift one end of the cold detector vessel with a crane and lifting fixture, and lift the other end (which is outside the building) with a fork truck?
What are the lateral and longitudinal tilt tolerances for the top of the cold detector vessel after it is installed in the warm vessel?
