Abstract
A storage and retrieval machine for depositing a load into, or removing a load from, a rack includes a horizontal drive, a vertical drive, and a lifting carriage comprising a load-accommodating unit having a plurality of adjacent, telescopic accommodating fingers that can be individually controlled. Each finger includes a carrier element that is fixed relative to the lifting carriage, a middle finger element, and an end finger element. The middle and end finger elements can be retracted and extended in parallel in both longitudinal axis directions relative to the carrier element. A linear drive element coupled to the middle finger element moves the middle finger element in a direction of its longitudinal axis. At least one coupling element provided on the middle finger element engages the end finger element and converts motion of the middle finger element into an additional motion of the end finger element in the same direction.
