en.Wedoany.com Reported - At 17:36 on April 13th, with the final command given, the 3BRX steel liner module three for San'ao Nuclear Power Unit 3 was steadily and securely "homed"!
CNNC Machinery Engineering successfully completed this "aerial precision docking" of approximately 160 tons in total weight over a span of 4 hours. The entire process was safe, quality-controlled, adding another crucial milestone to nuclear power construction!
As the "core protective barrier" of the reactor building's containment, the steel liner is the "steel armor" safeguarding nuclear power safety. This lifted module presented three major challenges: large volume, extensive wind-facing surface, and susceptibility to deformation during lifting. To tackle this "tough nut," the project department promptly established a "Party Member Vanguard Team," collaborating with various participating units to form a dedicated task force. Guided by the "red" spirit of Party building in leading the "blue" work of nuclear construction, they solved the problems through seamless cooperation.
Preparatory Work: Meticulous Refinement, Fortifying the Safety Foundation
Strictly enforced on-site cordoning, rechecked the safe clearance distance for tower crane avoidance, conducted walking simulations along the predetermined route for the crawler crane, and verified the alignment between command logic and working conditions.
The 2000-ton crawler crane performed lifting, slewing, and other operations, smoothly transferring the circular lifting spreader while simultaneously conducting tagline control, lifting point alignment, and rigging connection.
Conducted graded hook-up trial lifts, suspended to inspect module levelness, lifting lug and rigging load conditions, confirming the trial lift as qualified once all indicators met standards.
Lifting Execution: Precise Coordination, Ensuring Full-Process Control
Real-time synchronization of key information such as working conditions and wind speed, coordinated mitigation of intersection risks to ensure full-process control.
Strictly controlled hoisting, slewing, and travel speeds according to the lifting plan, smoothly completed repositioning and crossing, while continuously monitoring module posture, wind speed, and safe distances.
Achieved precise alignment through refined operations like limit guiding and auxiliary adjustments, with all parties cooperating to complete unloading and hook disconnection.
In the future, CNNC Machinery Engineering will continue to uphold its core values of "Responsibility, Safety, Innovation, Excellence," always adhering to the safety philosophy of "Safety First, Zero Tolerance for Errors." We will ensure the successful completion of every major lifting milestone with high standards, high efficiency, and high quality, contributing the brand strength of "Infinite Possibilities" to the development of nuclear power construction.
