The invention relates to tracking devices which make it possible to align appliances in accordance with an arc-shaped track. They are suitable, for example, for solar devices, such as photovoltaic generators, solar boilers and heliostats. The appliances to be guided are normally mounted rotatably around a vertical axis. According to the invention, the necessary tilting around a horizontal axis is achieved by at least one guidance device automatically with the rotation around the vertical axis. The guidance device links the part being guided with a fixed point. Conditions are specified which enable an exact or an advantageous approximate tracking. An arrangement for the precise tracking of a solar generator is shown in Figure 1. |
