The first picture shows 2 of the workers attaching three generating bank tubes together for the crane to lift up in the air and lower them into the rear area of the drums for stabbing. Our guys are stabbing tubes in the rear and front of the boiler.
The second picture is of a worker cleaning the generating bank tubes before moving it to the staging area to stab into the drums.
The third picture is the front view of the generating bank tubes. The worker has already stabbed the tube. He is getting the wench cable and the slings off the tube to send down to the floor area (which is the staging area for the front).
