A magnetic support and transport system comprising a plurality of permanent magnets for interacting with ferrous T-bars of a ceiling grid to counteract gravitational attraction. A plurality of rollers maintain an air gap between the magnets and the grid. A remotely controlled electric motor drives at least one of the rollers and thereby transports the system along the T-bars. Opposing pairs of guides maintain alignment of the system with the T-bars. Each pair of the guides is adapted to automatically retract upon encountering transversely oriented T-bars. When used for grid resurfacing and redecorating applications, the system can support a tape dispenser adapted to transfer adhesive pressure sensitive tape to downwardly exposed surfaces of the grid. A modified embodiment of the present invention is adapted to support surveillance equipment.
