At the Sears Catalog Marchandise Distribution Centre in Belleville, Beaver installed a four-level catwalk system to make full use of 39' ceilings.

The levels are all interconnected by PLC-controlled conveyor systems, with destination-programmable trolleys sent to any of 12 picking zones by a coordinating computer system.

Beaver solved an age-old problem by incorporating fire-exit markings directly into the floor tile.
