2.0 Overview
Constructed from a combination of hard-wearing stainless steel and
lightweight aluminium, the ABT5200 Sidecut Gauge is a compact
solution to measuring side and headwear.
The side and headwear are measured mechanically on a pair of
linear stainless steel scales via a horizontal and vertical slide
respectively.
The gauge measures the following parameters:
Sidewear
Headwear

4.0 Getting Started
When picking a measurement point, it is important to consider the
following points as they can cause an inaccuracy;
Location of welds or branding marks.
Excess loose rust, dirt and grease.
Once a suitable measuring position has been chosen, the gauge can
be attached to the rails. The gauge has 2 locating magnets, as shown
in Figure 1, which will allow it to stay connected to the rail; leaving the
user’s hands free to take the measurements.

Figure 2 shows the mating faces of the rail and the gauge. Once
the magnets have adhered themselves to the faces on the rail, the
gauge will hold itself in the measuring position, as shown in figure
3.

4.1 Measuring Sidewear
The sidewear measurement is the amount of wear caused on the
side of the profile by the contact of the wheel on the running rail.
To measure the sidewear, ensure the gauge is fully in contact with
the rail as shown previously then the horizontal measuring slide can
be adjusted as shown in figure 4.
Figure 4
Once the lower corner of the measuring pin is in contact with the
worn edge of the profile, the measurement can be taken from the
sidewear scale on the top of the gauge, as shown in figures 5 and 6.
The sidewear measurement is given as mm worn since the rail was
new.

4.2 Measuring Headwear
Headwear is the deterioration of the top of the profile as a result of
the friction between moving wheel and the rail.
To measure headwear, again ensure the gauge is fully in contact
with the rail, please push the knob or the sliding mechanism
directly and not the body of the gauge as this can cause the gauge
lockup, then the vertical headwear slide can be adjusted until the
measuring pin is touching the top of the rail. The headwear scale
on the side of the gauge will display the measurement for that
position.
Headwear is also displayed in mm worn since the rail was new.

5.0 Maintenance
5.1 User Advice
The ABT5200 is a precise measurement equipment. Whilst it has
been designed for use in an engineering environment, due care
should be taken not to cause damage to the equipment when in
operation, storage or transit. Excessive trauma to the moving parts
of the gauge may invalidate the calibration and lead to possible
measurement inaccuracies.
5.2 Every 3 Months
Visually inspect the ABT5200 for signs of damage. If necessary,
contact your local distributor for help.
5.3 Annual
The ABT5200 must be returned annually for re-calibration to ensure
measurements are within specification.
The condition of all components will be checked at this time and
replaced as required.
