ABSTRACT:
Transport apparatus comprises a drive unit and a slave unit movable in unison along a predetermined path. The slave unit is disposed beneath the drive unit to move along a tunnel with work stations located at intervals along the tunnel. The drive unit carries electromagnets which when energized levitate the slave unit within the tunnel, controls being provided to maintain the slave unit at a desired position relative to the drive unit. The roof of the tunnel is formed from a magnetically transparent material, such as glass. The slave unit is thereby physically isolated from the drive unit. As a result the drive unit is shielded from any hostile environment within the tunnel and resulting, for example, from the transport of radioactive or toxic materials by the slave units. This simplifies repair and maintenance operations on the drive unit.
