Because
the emphasis on our UK roads network is information and control, Dambach
have designed and produced a range of signs and systems to make the
motorists life easier.
It
is with this in mind that Dambach developed a range of prisms signs (known
as PR / PWS) that displays three different messages predetermined to cope
with local traffic conditions.
Our
PR/PWS signs consist of prism sections secured either into the front face
of the enclosure or set behind a clear vandal-proof plastic screen.
All are made out of 3mm aluminium sheet, folded and welded to suit
customer specification. The sign is then painted and sign faced as
required.
There
are basically two types of prism sign currently available, i.e. PR and PWS.
PR signs can have prism widths of 100mm, 150mm and 200mm with the maximum
sign face area of 2.5m x 5m (H x W). PWS signs have prism widths of
either 450mm or 500mm with a maximum sign face area of 7m x 8m (H x
W). These dimensions can be doubled with the use of a central
bearing carrier.
The
prism section is driven via worm gears and an industry standard DC motor
with overload protection with prism alignment being achieved using limit
switches.
To
allow system interface a controller is housed either within the sign
enclosure or set alongside in a separate cabinet to allow the local
setting of the VM prisms by key switch if necessary. |
