Abstract
Sector Lifting Tool (SLT) is purpose-built tool for the lifting and transferring ITER components. The purpose of SLT is to lift and transfer Vacuum Vessel (VV) and Toroidal Field Coil (TFC) from Upending Tool to Sector Sub-assembly Tool (SSAT). After the sub-assembly at SSAT in ITER assembly hall, 40 °Sector which is composed of VV, VVTS and two TFCs is transferred from SSAT to ITER tokamak pit. Sector Lifting Tool and lifted components are connected with the lifting attachments. The lifting attachments have a same function as adaptor for interface between SLT and lifted component. The weight of assembled 40 °Sector is about 1250 tonnes. SLT is designed to withstand even two times component’s weight considering the safety factor of lifting accessary.This paper describes the design of Sector Lifting Tool and shows that the structural integrity has been verified through analysis. The structural analysis was performed in accordance with the ITER load specification and tooling procedure. In analysis result, the stresses and deflections turned out under the allowable ranges.
