Station Harps
Harps are used instead of bays where many stations are to be arranged in small areas where they can
be served by one workstation. In order to save space, the stations in a harp are arranged diagonally or
perpendicular to the main loop and use a common re-entrance back into the main loop. Generally, the
same markers are used for stations in a harp as in the case of a station bay. Only the track elements
are combined in a different way. Since the stations in a harp are only served by one workstation, markers
controlling the traffic at the merge sections are normally not required (normally there is not enough space
for this). Instead, it is assumed that two Weasels will never be assigned or released at the same time.
Between the stations, there should be sufficient space for the personnel loading and unloading the
Weasels. The layout should also consider the side from which the Weasels are to be loaded/unloaded
and what type of products are handled. The app communicating with the Weasel vehicles at the
Station
and
Request
marker must not be too far away. A range of approximately 5 meters can be assumed (up
to 10 meters if conditions are favorable). If possible, with regard to the available space, you may even
use a
Group Request
marker at the beginning of the harp instead of individual requests for each station.
