The engineering of the R&D experimental workshop has completed the hoisting of the 1-7 axis overhead cranes so far. The successful completion of this work has opened up the working space for the installation of the 75-ton overhead crane after the Spring Festival, and has created favorable conditions for the running and debugging work of the overhead crane scheduled to be completed by February 20th in the construction plan. At the same time, the experimental water pool between axes 8-11 was poured on January 15th and the ground backfilling work has started today. It is planned to be completed by night today. Thus, the earthwork and foundation work of the R&D experimental workshop has basically been completed, which has also seized valuable time for the next step of hoisting the steel structure of axes 8-11 and the expected goal of completing all the main structures by the end of the Spring Festival.
