I put a rock on the conveyor first, then I put the motor, when I crossed to the other side, the ladder was down so I guess the rock did the job. Then I went up the ladder, retrieved the motor and continued on.
Weird...I don't even remember having to take down the ladder like that...perhaps I missed something, or accidentally knocked it down without noticing, but I swear the ladder was already in climbing position when I entered the room.
That was the case for me too.
I just put the motor on the belt in the entrance area, without any reason at all, just to see what would happen.
The motor was then lying on the walkway with the ladder already down.
this is the ay i did it :)
