Last week they lifted a large beam to the podium. I now see that they doubled up on the lifting cables from 2 to 4 for mechanical advantage which probably reduced the available lifting height. Maybe that explains the extra longer straps?
This morning they used two cranes to lift this beam to the top working level. I have not been paying that much attention to see if they are lifting all these beams with two cranes.
Is this for ease of installation or lifting capacity? Maybe the east crane operator is looking for more work as the podium nears completion of the structure.
I never did well in mechanical components class.
