2.2.13 Lift Panel - See Figures 2.2-27 and 2.2-28
1. The Lift Panel on the Work or Tie Finder Main Screens displays the following:
(1) Lift Slider
(2) Lift Slider Info Box
(3) Direction Indicators
(4) Manual Correction Lift Slider
2. The right Lift Slider (1) highlights yellow to indicate the current lift that is being applied.
3. The Lift Slider Info Box (2) numerically displays the current lift that is being applied in
increments of 1/16 inch.
a. When the lift applied exceeds the range of the Lift Slider, the lift numerical value must
be read from this info box.
b. The info box does not indicate a plus symbol (+) for a positive increase of applied lift
or a minus symbol (-) for a negative decrease of applied lift, only the value of the
applied lift in the indicated direction of the Arrow Indicators.
4. The cyan arrow Direction Indicators (3) indicate whether the lift being applied is positive or
negative. A positive increase of lift is indicated by an up arrow and a negative decrease of
lift is indicated by a down arrow.
5. The Manual Correction Lift Slider (4) displays the total amount of any manual lift correction
that is applied when using Auto Ramp (track that is pre-recorded). The slider will highlight
green to indicate a positive increase of lift being applied or highlight red to indicate a
negative decrease of lift being applied.
6. When using optional pre-recorded surface data, System V can automatically vary the lift to
compensate for errors at the projector, to minimize the lift and to automatically work into
and out of fixed points (i.e. bridge). The operator retains full control at all times and may
increase or decrease the value of lift being applied by the computer. Such adjustments will
be shown in the left Manual Correction Slider.
7. The lift expressed by the right Lift Slider (1) corresponds to the lift that will be applied on
the next cycle to the track. When the track being tamped has not been pre-recorded, this
value will be an average value and will exclude variations in lift arising from track errors.
When System V is automatically controlling lift from pre-recorded surface data, the
indicated lift value should accurately reflect actual lift for a properly calibrated machine in
good conditions. Poor conditions such as inadequate or foul ballast may result in
