Installation of Track Items
This aspect of the installation involves fixing of the wheel sensor to the running rail, fixing of the Blade
system and running of the feed delivery hose system.
10.1
Wheel sensor
The wheel sensor is a non-contact proximity device that will detect a passing wheel when correctly
set. The unit is pre-assembled on an aluminium mounting plate and needs to be clamped to the rail
3 to 6 metres upstream from the furthest rail mounted Blade. The sensor will be in the “4 foot”
and can be on either rail as best suited to the site.
There are two forms of wheel sensor:
o
Fixed sensor as pictured below right and using a rail clamp at each end of the sensor
bracket.
o
EasiSensor pivoting sensor as pictured bottom right which fits between the sleepers and
has a single hook bolt to clamp it to the rail. Fixing details are described below.
10.1.1
Fixed Sensor
Sensor rail fixing clamps are similar to the
blade rail fixing clamp and fitting is generally
covered in Section 10.4, the key differences
are:
o
Space the clamps to suit the sensor
brackets.
o
Fix one clamp on each side of the
sleeper.
Clamp the sensor to the M16 rail clamp studs
with the sensor uppermost.
Adjust the height of the sensor to 42 / 45mm below the rail head crown and securely tighten the
M16 fixings.
10.1.2
EasiSensor
Sensor rail fixing clamps are similar to the EasiBlade
arrangement and fitting is generally covered in
Section10.6, the key differences are:
Clamp the sensor to the M16 rail clamp studs with the
sensor uppermost.
Adjust the height of the sensor to 42 / 45mm below the
rail head crown and securely tighten the M16 fixings.
Note: If required by site conditions the sensor can be
reversed on the sensor mounting plate such that the cable
exits in the opposite direction.
