Try to concentrate on the most difficultA level of difficulty has been determined (1/3) to focus on most difficult casesLevel 3: QURC US85, US25, PM18The actual status: 12/13 cold boxes are installed, PM18 QURC in June 2005

QURC UX85 a challenge to prepare anotherInstallation in US85 passing by UX85 throughout tampon wall: Demolition of the wallDeviation of general services and gas systemInstallation of 20m long Z rail on the vault (to avoid interference with crane)Preparation of US85 floor to roll electrical switchboards and installation of manifoldUse of hydraulic extra short jacksVery spectacular flight and installation

QURC US25 no space, no means -> 3D simulationDefinition of maximum overall dimensions of AL componentsInstallation of 15t hoist and rail on the US25 vaultDefinition of transport means

QURC horizontal partQURC higher than metallic structure (dismounted)Maneuver with no room - > special roller seat + reduced high spreaderQURC width 1900mm, shaft dimension 1950mm -> nylon pads to allow loweringPosition of centre of gravity not correct to lift in US25 and rotate to final position -> addiction of counterweight in feet to compensate

QURC Vertical partQURC longer than shaft -> need to be tilted with hoist chain system, special spreaderQURC width 1900mm, shaft width 1950mmIn underground extra-short rollers (110mm) to pass under the metallic structureRotating ring to be welded in the lower part to permit passage from horizontal to vertical in the US25: behind a rotating/rolling cradle, in front hydraulic shortenable spreader on the hook seat to liftCounterweight on the back to correct center of gravity positionInsertion of K supports under QURC feet when suspended

Conclusion 12/13 cold boxes are in places. Installation has been successfulDetailed handling studies (3D, tools definition and construction) have been requiredCoordination with different technical sectors (CE for rail and walls, EL for cabling modifications, CV for pipes de-routing, .) was goodSafety aspects have been studied in detail with all safety procedures respectedOverall cost of installation has been ~350kCHF, i.e. 1% of the 12 cold boxes valueLast challenge QURC in PM18 soon!!!
