ABSTRACT:
The ladder system is located adjacent the front face of a storage rack. The ladder is carried by a cantilever supported carriage assembly having a pair of pivotally mounted frames. The ladder is connected to one frame and may move longitudinally along the front face of the storage rack. The ladder and its frame may also be moved laterally in an arc up to 90.degree. in a direction extending perpendicular to the front face of the storage rack. The carriage assembly includes a horizontal ladder support arm on the first frame upon which the ladder is mounted. A user can quickly and easily position the ladder at any position along the storage rack for accessing items stored on the shelves. This ladder system is particularly useful in crowded warehouse-type retail outlets which are now in popular use across the country.
