Truss cap with standard interface

Adjustable bearing supports for single-axis trackers supported by truss foundations. A two-piece assembly joins a pair of adjacent truss legs to form a rigid foundation while providing a movable support for a tracker bearing housing assembly or other structure. The movable support may slide in-plane, or alternatively, enable the bearing housing assembly to slide and rotate with respect to the truss cap structure joining the adjacent truss legs.

Tracker bearing support

Single-axis solar tracker bearing adapter

A truss foundation for single-axis trackers that is optimized to resist moments. For foundations that experience lateral loads as well as moments, the foundation supports the rotational axis via a moment connection that is deliberately offset below the work point to reduce the impact of the bending moment. Spacing between the truss legs and the angle of the legs impact the height of the truss work point and, by extension, the available offset below the work point down to the minimum height of the axis of rotation specified by the tracker maker.

Tracker motor support for truss foundations

Systems and methods for quickly and securely interconnecting foundation components when axially misaligned without hydraulic tools. Upper to lower leg connections are made with threaded connections or with ball and socket connections that permit angular adjustment. One or more retaining nuts bias the connection to lock it in place at the desired orientation. Foundation component to single-axis tracker connections are facilitated by various wedge and clamp connector assemblies that rely on mechanical engagement to lock components in place and resist axial forces. Other connections are made with hemispherical washers and adapter plates that enable rigid connections through a range of angles.
