A couple of observations. First, is the crane they are using now one of the cranes they will use to put the crossbeam in place? It looks like the same series as the all-terrain Grove GMK7550 crane mentioned in post #
110. Hard to tell what model it is sitting behind all that steel, but it appears to have the height capacity and it handled those smaller sections easily.
Scottie33 comment. The crane insure now is a grove 5200 series and for comparison sake this crane can only lift 86,000 pounds at 148.8 stick length and 25 feet away... The biggest question that looms is how much does the actual cross truss weigh and then the determination can be made to what cranes are needed. Hard to tell exactly when the total tonnage of section is unclear... All speculation at this point
Second, late afternoon yesterday, they were using a bobcat to break out a couple sections of concrete along its west edge between the west tower and the crossbeam section. I think they were also digging into the hillside, but it was hard to tell because it was on the edge of the video feed. Are they preparing the site to place the crane? The sections of concrete removed are about 30 ft apart which matches the specs for the crane’s pad placement.
Lastly, if you look closely at the crossbeam section, you can see the 4 attachment points the cranes will use to lift it into place. You can see them along the top edge. They are 1 section in from each end.
