3. Heavy Lifting in Power Plant Construction Wall panels are assembled at ground to reduce # of components being lifted
Heavy wall panel assembly weights up to 400 Tons
Strand jacks are provided on the structure
Lifting beam / truss is used to spread the load evenly to multiple lifting points
An approved Rigging Plan is required for critical heavy lifts
