Conclusions Good news: • Access with a lift truck is possible • Lifting the module out with the fork lift and special spreader (interfacing with proposed lifting support frame) is feasible. (four people guiding) • EN-HE can design and build a special spreader beam for this test But: • The clearance of ~3 mm is very tight • This raises questions: – What will happen when adjacent modules touch during the lifting process? – Level of confidence in centre of gravity position? – Will it be possible to see the parts that are at risk of touching?

Recommendations • For installation in the tunnel EN-HE proposes the use of pre-adjusted spreaders for different module types. • Given the rate of installation needed and small clearances EN-HE recommends mechanical guides on adjacent modules to guide installation (automated precise transfer à la LHC cryomagnet transfer table installation would give transfer times too long for CLIC required installation rates) • An automated spreader will not be a long term solution for tunnel installation – (Note: adjustable spreaders are normally adjusted when unloaded)
