A combined balance beam is widely used in lifting of large structure module and containment vessel（CV） in the nuclear power project

which has the advantages of small longitudinal deformation and simple hoisting tool

also has the disadvantages of high cost and low efficiency.Based on the lifting of stainless steel pool liner in CENTER project

according to optimize quantity and location of lifting ears

this thesis gives a new construction technology without balance beam.The new technology can ensure controllable lifting deformation

avoid the use of complex structure

high cost and heavy balance beam

reduce the lifting cost

simplify the hoisting process

and improve the availability of crane.This construction technology has a certain reference for the lifting of large cylinder structure.
