meeting notes: Transport in TT2A; 15.Sept.2004: S.Prodon, Y.Bernard, A.Fabich
 | Y.Bernard replaces J.Bernard. | ||||||||||||||||||||||
| The maximum weight to transport "easily" is 3.6 tons, which is the limit of the "tortue" (turtle transport utility, picture, picture). An item exceeding this weight is transportable, but gets more complicated (=time). | ||||||||||||||||||||||
| The beam attenuator (iron 160x80x80 cm) should be installed in several pieces with a base of concrete. | ||||||||||||||||||||||
| The metallic chassis of the nToF cooling unit has to be removed for transport into TT2A or at least partly modified and reinstalled. | ||||||||||||||||||||||
| A second floor of concrete will be installed from the step at the junction of TT2 and TT2A to the first quad in TT2A in order to handle heavy items more easily. The step has a height of 45 cm. | ||||||||||||||||||||||
| The double concrete wall on the north side of the TT2 tunnel at junction is unused. It was installed for a previous design of the nToF line. Its removal is difficult (as it is a single concrete wall, not individual blocks). Edges could be modified to allow a larger entrance width. | ||||||||||||||||||||||
| The weight and the dimensions of the solenoid should be verified: According http://198.125.178.188/bnlpulsed/bnl-001R1.pdf the outer dimensions are length=1.8m, width=?1.3m and height=?1.3m; The weight is about 4 ton. | ||||||||||||||||||||||
| The base plate of the solenoid should be designed in collaboration with the transport team to have an usable interface to the transport utilities. | ||||||||||||||||||||||
| The width of the turtle is 134 cm. Maximum weight for transport is 3.6 tons. | ||||||||||||||||||||||
| Measured passage at the junction is 135 cm. According to the ACAD drawing it is 140 cm. | ||||||||||||||||||||||
| 1 team = 3 persons | ||||||||||||||||||||||
