Great question.

What type of facility is this in?

I've done 2 recently.

2:1 Over head and a 2:1 basement machine.

Basement machine was in a power plant. I had their onsite scaffold crew erect a scaffold. I also positioned the counterweight to where the cartop was level with top landing to provide room for working and the scaffold above the cartop.

The over head we had enough room in the secondary to sit on beams and use a rope to pull up the shackles to put into the hitch plates.
