  • Patent number: 11967922
    Abstract: A universal adapter for enabling truss foundations to support conventional single-axis trackers. In some cases, the adapter has a main body with an upper portion that presents a standard I-beam interface with pre-drilled holes to interface to a specific single-axis tracker. A pair of connecting portions point down and away from the main body and enable upper leg sections to connect the adapter to a pair of driven screw anchors located below it. The connecting portions may orient the truss so that the rotational axis of the single-axis tracker is aligned with the work point of the truss foundation made from the adapter, upper legs, and driven screw anchors. This will enable to the truss to interface with many different trackers much like conventional plumb-driven H-pile foundations.

  • Patent number: 11953041
    Abstract: A machine for rotary driving screw anchors into underlying ground and related. The machine has a mast with a rotary driver and a mandrel driver oriented on a common axis. The mandrel driver passes a mandrel through the rotary driver and the screw anchor to allow the mandrel to be actuated ahead of the screw anchor while the rotary driver drives the screw anchor into the ground. Alternatively, the mandrel driver may also drive a hammering drill through the screw anchor to clear a path ahead of it through subsurface rocks.

  • Patent number: 11926981
    Abstract: A foundation system for manufactured homes, prefabricated houses, and other structures. Multiple screw anchors are driven into the ground at the desired location of the structure. Preformed grade bars may be placed over the screw anchors to provide a modular foundation without pouring concrete or digging footers. Alternatively, adapters may be attached to one or more of the driven screw anchors to provide a pedestal to receive the grade bar or prefabricated sections of concrete.

  • Patent number: 11894801
    Abstract: 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.

  • Patent number: 11606059
    Abstract: An A-frame-shaped truss foundation system for a single-axis tracker with a bearing assembly sitting atop a pair of adjacent angled truss legs joined together with an adapter so that the axis of rotation of the tracker is aligned with a work point of the A-frame. Several such foundation systems are arranged along a North-South row to support a tracker torque tube.

  • Patent number: 11121671
    Abstract: A single-axis tracker supported by multiple A-frame-shaped single-truss foundations that translate lateral loads into axial forces of tension and compression, and at least one truss foundation supporting the torque tube drive motor or other tracker component subject to axial loads to provide support for lateral loads as well as loads oriented along the axis of the torque tube.

  • Patent number: 10934677
    Abstract: A machine, method and system for installing helical foundation piers that sues a driving tamper connected to a rotary tool to drive helical piers into the ground. Once the pier reaches the target depth, the tamper is decoupled, and counter rotated away from the pier. While it is withdrawn the soil between the driven and pier and the driving tamper is compressed by intermittent downward action of the tamper.
