On October 18, 2018, the 203 overhaul progressed into the 18th day in an orderly manner. Two gates of Unit A (2CFI001BU and 2CFI003BU) of Unit 2 were lifted from the main line on the workstation. As the main body of this project, Wanna Lifting Project Department has Be prepared and ready to go.
At around 2:30 pm, the work ticket was retrieved, and the operation team staff was in place. As the maintenance support department, the work was focused on the work. The relevant staff of the service department had already been waiting at the 2PX outdoor work site earlier.
To meet the lifting conditions of the sluice, the balance valve needs to be opened to discharge water, and the liquid level difference between the two sides of the sluice should be adjusted within 0.8 meters. The overhaul period must be counted against every second. It is most time-saving to lift the standard 0.8-meter liquid difference node, and the shift is on duty for 4 hours. The liquid level is always paid attention to. The lifting conditions meet the requirements, and the gate lifting work begins.
At 7:30 in the late autumn, the night is already thick, with cool breeze, stars and raindrops, revealing the coolness, coupled with the small space in the PX outdoor area and the complicated environment, increasing the risk of this lifting work. All operators tightened the safety string and supervised each other. The on-site supervisors paid close attention to each risk point of the lifting process and reminded them at all times to ensure that the entire lifting process was carried out safely and orderly.
The secret to the successful completion of this task lies in the high sense of responsibility of each member of the staff, and always adhere to the safety barriers of each post, the road barriers interweave a solid safety net to protect the safe operation.
Responsibility is in mind and responsibility is in line. Wanna lifting team will, as always, meet the high standards of the maintenance support department to meet every challenge.
