  Eleven years have passed between the beginning of transport and handling studies in 1996 and the completion of the LHC cryo-magnets installation in 2007. More than 1700 heavy, long and fragile cryo-magnets had to be transported and installed in the 27 km long LHC tunnel with very restricted available space. The size and complexity of the project involved challenges in the field of equipment design and manufacturing, maintenance, training and follow-up of operators and logistics. The paper presents the milestones, problems to be overcome and lessons learned during this project.

  Experimental modal analysis of components of the LHC Experiments is performed with the purpose of determining their fundamental frequencies, their damping and the mode shapes of light and fragile detectors components. This process permits to confirm or replace Finite Element analysis in the case of complex structure (with cables and substructure coupling). It helps solving structural mechanics problems to improve the operational stability and determine the acceleration specifications for transport operations. This paper describes the hardware and software equipments used to perform a modal analysis on particular structures such as a particle detectors and the method of curve fitting to extract the results of the measurements. This paper exposes also the main results obtained for the LHC Experiments.
