were disconnected and removed. No.4 other Skid
shoes were positioned onto some transversal skid
tracks (90 degrees). Skid shoes for transversal mo-
vement, were skidded under the support frame
(where the reactor was stored) and took the load of
the heavy item. Skid shoes are provided with inter-
nal jacks able to lift the base where the item is leant
with a useful stroke which can adjust the correct
height to take and secure the whole load without
any unforeseen movements.
Once the reactor was connected to the “transver-
sal” skid shoes, it was eventually skidded, reaching
the foundation area (pict.09). Once checked that

by means of the skid shoes lowering stroke system
and bolted. Fagioli equipment was then discon-
nected and removed (pict.10).

Final conclusions

This was a milestone operation for Fagioli. In terms
of engineering and heavy haulage and lifting opera-
tions, Fagioli was compelled to find the perfect and
zero-accident solution for the transport and instal-
lation of the 458 ton reactor. Fagioli door-to-door
