The Side Level Measuring
Trolley (SLMT-D) is a lightweight self-contained
instrument for measuring the variation in height
of material surrounding embedded rails in urban
transport systems and rail / road crossings. The
SLMT-D facilitates recording of rail height and
Keeper rail height compared to the surrounding
infill material for maintenance and safety
monitoring.
When using the SLMT-D under non-possession
conditions it can easily be lifted from the
track during a measurement task and returned to
the track following the passing of a train.
The equipment produces a hard
copy profile of 5 side level and 1 Keeper rail
measurement on the integral 100mm wide thermal
recorder. Additionally all measurements are
stored digitally on a PCMCIA memory card in
order to allow offline analysis within a PC
environment. Operation of the instrument is by
simple mechanical and digital parameter setup
using the LCD display and keypad which is
mounted in a waterproof pod on the side of the
recorder. All data recording is distance based
and therefore is independent of the speed of
travel.
