Where must the truck/lift be positioned?
The ladder and the balcony or window must be in a same vertical line. This is to allow the top of the ladder to rest squarely on or against the balcony rail, or window sill, or wall just below the window sill. In some cases an angled landing stage can be built to allow the top of the ladder to rest squarely despite the ladder being set up slightly to one side. The distance between the wall and the base of the ladder must be no more than approximately 10 metres.
