Application areas
The WCS can be used anywhere where material handling equipment has to be positioned
precisely. The functional principle of the WCS enables it to be used in a diverse range of
applications, such as:
Interruptions in the code rail (lane changes, track switches)
Applications with curves and circular paths
Use of multiple vehicles in a row
Due to the larger tolerances of the reader in relation to the code rail, in most applications the
WCS3 system can be used. In some circumstances, however, it is advantageous to use the
WCS2 in conjunction with the aluminum profile system. Here are some examples from the
variety of application options:
Stock Feeders (High-Bay Warehouse)
Trolleys, lifting gear, and transversing carriages are each positioned with one reader. The
positioning is independent of the length of the code rail and always absolutely reproducible. For
new high-bay warehouses we recommend the WCS3 system. For retrofits in older warehouses,
it may be beneficial to use the WCS2 in conjunction with the aluminum profile system:
Easy to retrofit
High mechanical tolerances between the measuring system and moving carriages
possible
Decoupling of vehicle vibrations

Automatic Cranes
Automatic cranes are a typical application for the WCS2 in conjunction with the aluminum
profile system. The crane is positioned using one reader each for the crane and the trolley
movement. At each point, the guide trolley ensures the optimum position of the reader in
relation to the code rail and decouples any vibrations from the crane track. Optional cleaning
brushes for the code rail can be attached to the guide trolley. This means that the WCS2 can be
used in a very dusty environment, such as in cement works or foundries.
