Arrangement for moving loads through an environment

摘要

It is described an arrangement (20) for moving loads (12) through an environment (10), for example containers for storing disklike objects such as wafers or the like through a semiconductor fabrication. Said arrangement (20) comprises at least one track (21), at least one conveying means (22) being movable along said track (21) and holding said load (12) and at least one light source (25) for supplying an energetic light radiation (28). Said conveying means (22) is comprised of an electric drive (29) and means (31) for converting said energy collected from said light source (25) into electric energy for said electric drive (29). Means (31) can comprise a number of solar cells (32). This will enable an uninterrupted operation of said conveying means (22), for example a specific vehicle, since the electric drive (29) will always be properly charged by electric energy, said electric energy being produced by said solar cells (32).
