Zusammenfassung:A truss foundation for single-axis trackers that are installed in climates that experience significant frost heave. In some cases, truss legs are oriented plumb, to eliminate adfreeze moment on below-ground components in the frost zone. Different truss caps may be used depending on the type of single-axis tracker and/or tracker component is supported. In some cases, truss legs may curve just before entering the ground. In others, below-ground and above-ground components may extend along the same axis and remain plump with the truss cap providing additional elevation to for the tracker to clear the wider truss legs.
