Lots of ways to do this. Hang all three reels on a pipe in the pit. Car at top of hoistway .Remove cables from cwt. Remove cables from comp sheave. Shackle up cables to cwt. They cant cross unless you remove them from reels. Run car down to pit. Using car to sling from, repair comp sheave. One at a time, reeve cables through comp sheave. Shackle up to bottom of car. I have done this on 30+ floor elevs and never crossed a rope. When cables were babbitted on the bottom of the car, It was a little trickier.
