<p>This invention concerns a tracking device which enables the positioning of an apparatus to trace a curved path. For example, they are suitable for solar devices such as photovoltaic generators, solar cookers and heliostates. Normally the tracking apparatus is mounted on a vertical axis, whereas according to the invention a necessary tilt to the horizontal axis is attained automatically through a directing limb by rotating the vertical axis, this making possible a trustworthy and uncomplicated manufacturable and manageable tracking device that can be easily adjusted to the local circumstances.</p> |
