Saw of heavy turbines
Saw of heavy turbines :
100 ton positioner, 0° to 105° hydraulic tilt, tilting torque 130000 kgm, rotation torque 16000 kgm, table Ø 3700 mm with 8 extension arms to Ø 8000 mm connected by checker plates for load / unload items.
UE Manipulator, strokes (hor. x vert.) 7x6m, rotation of the motorized column 0.1 rpm on a motorized base, equipped with SAW Tandem heads installed on MM MIDI 250/2 HD motorized slides controlled by IG tactile joint tracking system and above all combined to a 0° to 50° tilt fixture allowing to align their vertical axis (in diving execution) or to tilt it to 45° according to the horizontal boom.
Such plant indeed had to meet with the particular turbine geometry and with the the joints to be performed as well. For these reasons the operator had to sit at the end of the boom being «sank» approx. 1500 mm below the boom lower face.
Being not possible, according to safety rules, to let the operator seat on a specific armchair located on the lower end of a «diving» slide, the problem was solved by tilting a section of the boom end of about 1800 mm long without affecting the boom horizontal work stroke which was about 5 m with its end tilted, while reset to 7 m when its end was brought back to horizontal position.
