Abstract
The disclosed ladder system may be disposed in a store, warehouse, library, or similar facility where two storage shelves form an aisle. The ladder can be pivotally attached to a roller structure that moves along a length of the aisle on a guide track. The guide track may be disposed along sides of the storage shelves. The roller structure may be formed by a lateral rod extending between and coupled to two roller carriages. Further, because the ladder is pivotally attached to the roller structure, the ladder may fold substantially out of the aisle when the ladder is not in use.
