( absolute input mode )

Handling of the geometrical arrangement of line towers (ropes in the roller assemblies on ascent and descent branches) is carried out by means of the following data input mask:

Up to 80 line towers can be loaded, setting the absolute values for the rope progressive distance and height values. Non parallel branches are excluded from rope-way systems: the relevant mask has been kept for homogeneity reasons, but cannot be used.

Three pushbuttons are provided for the following, respectively:
- addition of a new line
- deletion of a line
- table emptying
- calculation of the length and difference in height for each single span.

The first two pushbuttons are only active for a certain position of the mouse (on the column showing the tower number): a suitable coloured label shows the actual condition. In the example below, the Tower NR.4 cell has been clicked, thus, the pushbutton for the addition of a new line or the deletion of that line is now enabled.

For line calculation, the values relating to the "Rope Progr.distance" and "Rope Height" columns are of fundamental importance; the other values can be omitted (or loaded later)
