Traffic Light Pole
Figure 1 shows a traffic light pole.
The structure consists of a tower crane-like frame with four stay cables, which are marked by the numbers. Figure 2 shows a side view of the intersection region.
The stay cables are tensioned by turnbuckles, which are connected to the circular hollow profiles by eye bolts. A schematic lateral view of two traffic light poles is shown in figure 3.
| Structure 1 | Structure 2 |
Structure 1 represents the above shown light pole with a single front stay cable instead of two; there are a total of three stay cables and three turnbuckles. Structure 2 has a single uninterrupted stay cable with one turnbuckle; the cable passes over two saddles. The red arrows represent forces, assuming that the structures are equal except for the previously mentioned.
Figure 4 shows the back sector and an enlarged view of it.

Stay cable 4 is connected to an eye anchor rod by a turnbuckle; an offset between the eye anchor rod axis and the stay cable axis is noticeable.
