2. Screw jacks – technical data
KTE : 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
17
Lifting – 6 points
18
Lifting – 8 points
19
Lifting – 10 support points

Proposition 1 Use simplified hydraulic system for lifting and screw jack as pernament support
21
Before lifting
22
Lifting by hydraulic Jack
1. Insert four hydraulic jack under carriage and lift up Target Spectometer
23
Insert, put down Target Spectometer on screw jacks and remove hydraulic jacks
2.Insert six screw jacks as a pernament supports
24
