2. The LaserSweep™
system is supplied with a rugged PDA as standard, which is
installed with the LaserSweep™
operating software and features Bluetooth®
connectivity. When combined with the standard internal battery, this ensures a cable
free measurement system highly suited to the rail environment.
Full profiles, part profiles, and single points can easily be captured, ensuring efficient
use of time on track.
The output from the LaserSweep™
is directly compatible with Balfour Beatty Rail’s
ClearRoute™
software, for analysis and investigation of vehicle clearances following
the survey.
The LaserSweep™
system has been designed and built to meet with the UK’s
statutory and safety regulations and has been awarded Product Approval by Network
Rail.
3. The LaserSweep™
is a well proven, versatile and portable measurement system
which is used to measure the spatial position of railway structures and features
for the purpose of calculating clearances.
The product has been extensively used on Network Rail and London Underground
infrastructure, and internationally in North America and Australia. The
LaserSweep™
has a proven record of reliability and performance within its field.
The system is rail mounted and designed to enable the user to undertake fast and
accurate spatial measurements of a range of railway infrastructure. This includes
tunnels, overbridges, underbridges, platforms, signals, station canopies and
discrete points such as OLE and cable brackets.
