Height warning system
Height warning system type HWA – quick and easy
The mobile height warning system HWA by Peter Berghaus GmbH serves the purpose of preventing
damage to bridges and vehicles not only during construction work or when the road layout has been
changed. At a certain distance before the bridge or underpass, a heated special light barrier system
with directional logic measures the height of all entering vehicles. If the adjusted vehicle height is
exceeded, an acoustic alarm is triggered for five seconds. At the same time, the bright two-aspect
300 mm Ø LED signal heads positioned about 30 metres before the bridge or underpass switch
from amber to continuous red for this particular vehicle. The vehicle that is too high is stopped,
thus effectively preventing accidents with damage to building structures and vehicles.
The system is reset with a key, a time module, by radio or SMS message, depending on the option.
The height warning system can be installed quickly and easily at any location using our mobile mast
system. Precise alignment is possible with our laser alignment set, available separately. Power is
supplied by 12 V batteries or from the 230 V mains supply. The control unit is accommodated in
a watertight lockable casing (IP66) and is equipped with a mains/battery changeover function as
a standard feature, together with low voltage protection and reverse polarity protection.
All parts such as light barriers, horn, signal heads and key-operated push buttons are connected
by means of watertight plug-in connectors (IP67). Typical applications for the mobile height warning
system include for example: bridge structures, railway underpasses, tunnel roads and entrances
to depots, underground car parks or multi-storey car parks etc.
