XXVIII PANDA Collaboration Meeting – GSI - Darmstadt, March 2-6, 2009 1. Hydraulic lifting system of the Target Spectometer – current design 2. Proposal for lifting the Target Spectometer with using screw jacks Cracow University of Technology Mechnical Design Group W. Czyżycki, M. Domagała, G. Filo, M. Hawryluk, E. Lisowski

1. Hydraulic jacks – concept Concept scheme Drive and positioning system for Target Spectrometer: 1 – carriage 2 – wheel 3 – carriage support 4 – carriage frame 5 – wheel 6 – hydraulic jack 7 – ball joint 8 – central support structure (without carriage)

Rail system 1 – flat rail 100x60 acc. DIN 1017 material: St 70-2/E 360 acc. DIN EN 10025 2 – support profile HE 300M acc. EN 10034:1994

Carriage design 1 – concrete foundation 2 – I support profile HE 300M acc. EN 10034:1994 3 – flat rail 100x60 acc. DIN 1017 material: St 70-2/E 360 acc. DIN EN 10025 4 – carriage 5 – electric motor with gearbox and brake system

Carriage design- dimensions motor: ZBA 100 AL 4 B050 gearbox: AUK 90 TD frequency inverter: Dedrive Compact DIC-4-025

1. Hydraulic jacks - carriage

1. Hydraulic jacks ENERPAC Synchronous Lifting System Synchronous system – 4 to 64 support points Hydraulic pump Control panel Hydraulic cylinder Linear displacement transducer Hydraulic hoses Wires Solenoid valves Pressure transducer Load: 100 t per point +/- 1 mm deviation

1. Hydraulic jacks – technical data ENERPAC model CLP1002: max. load: 100 t stroke: 50 mm A: 137 mm B: 187 mm D: 175 mm E: 136.7 mm F: Tr 136x6 H: 21 mm J: 126 mm K: 8 mm R: 5 deg S: 31 mm mass: 26 kg Lock Nut security mechanism Optional special synthetic coating allows to transfer lateral loads (up to 3% of maximum load)

Lifting – FEM Analysis- Shell model

Lifting – 6 points-displacement

Lifting – 6 points- stress

Lifting – 4 points

2. Screw jacks – alternative solution for pernament supports

2. Screw jacks Power Jacks Group South Harbour Road, Fraserburgh, Aberdeenshire, AB43 9BZ, Scotland, UK tel: +44 (0) 1346 513131 fax: +44 (0) 1346 516827 email: sales@powerjacks.com web: www.powerjacks.com

2. Screw jacks – top plate View of the srew jack Screw jack in the support with designed components

2. Screw jacks – technical data KTE18100-0100-1: Keyed, Upright, Translating Max. load: 1000 kN Stroke: 100 mm Worm gear ratio: 36:1 Turns of worm for raise of screw: 3 for 1 mm Mass: ~540 kg

Lifting – 6 points

Lifting – 8 points

Lifting – 10 support points

Proposition 1 Use simplified hydraulic system for lifting and screw jack as pernament support

Before lifting

Lifting by hydraulic Jack 1. Insert four hydraulic jack under carriage and lift up Target Spectometer

Insert, put down Target Spectometer on screw jacks and remove hydraulic jacks 2.Insert six screw jacks as a pernament supports

Comparison Hydraulic and screw Jacks Screw jack:Turns of worm for raise of screw: 1 for 0.33 mm Mass: ~540 kg Displacement 4P-1.425 mm 6P-1.636 mm Displacement 6P-2.099 mm 8P-1.919 mm 10P-1.888 mm Hydraulic jack B: 187 mm D: 175 mm E: mass: 26 kg

Proposition - 2 Use only hydraulic jacks

Proposition – 3 Use only screw jacks
