An RTG is a large CHE that can create large container stacks and deliver and receive container to and from UTRs and
over-the-road trucks. RTGs vary from 50’ to 100’ in overall height, depending upon the make/model. Sample RTGs are
shown in the following photos.
Variations among RTG manufacturers and specific models exist
and their impact on the specific installation of the WNC, PTIU, and
sensors are the responsibility of the customer.
The PTIU is housed inside a NEMA enclosure that is usually
installed in the equipment room of the RTG. The PTIU generally
connects to the RTG PLC in order to obtain the necessary telemetry
data. In some cases, PACECO has installed sensors in lieu of the
PLC interface. The Gen1 WhereNet products on an RTG are: one
STHO WhereTag, one buddy WTIII, two hardened WPs, two
rugged WP mounts, and two WP health tags. In a Gen2
configuration, the STHO WhereTag is deleted and a WNC is added.
In addition, a compass is also added if the site has no RTLS
coverage along RTG runs.
A block diagram of the components and connectivity of the Gen2 hardware is shown below.
