I posted some time ago how I had worked for a number of years as a labourer repairing the old heritage buildings in downtown Vancouver, many of which had ladders like the fire escape ladders on the Cecil Hotel. And yes, I worked on the Cecil Hotel in Vancouver, long before it was torn down.
I carried lots of heavy stuff up and down the vertical ladders. I was really strong then. I cycled, practised Judo, weight trained, and worked as a labourer. But it would have been a real strain for me to carry a 115 lb body up a vertical ladder. You would have to have very strong legs, back, shoulders, arms and hands.
And a second guy wouldn't any help. What would he do? Push on your



from below? Pull you hair from above? You have to climb up the ladder at least 2/3 of the way before the second guy could possibly reach down and pull up the body.
Think about it. To carry a 115 lb body up a vertical ladder, you would sling it over your right shoulder. The body is then between you and the ladder, which restricts your ability to climb up the ladder, and the body would push you away from the ladder. Your right leg would keep hitting parts of the body, and you couldn't use you right side and hand much because you are balancing the body to keep it from sliding off your shoulder. So you would be pulling yourself up with your left hand and arm, and stepping up one wrung at a time. And grunting a lot.
Most people can't carry a body up a vertical ladder that has more than a few rungs. Been there.
Next idea is that he can pull the body up the ladder up with a rope.
What rope?
The rope that is kept in a hotel room to pull bodies up to the roof?
