US Patent 11874029 Systems, methods, and machines for joining truss foundation components

A coupler for joining truss leg components provides angular adjustability between the respective axis of the leg components. A prolate spheroid-shaped coupler with three channels circumscribing its surface enables the upper leg components to compensate for axial misalignment of driven screw anchors in all directions. A hydraulic crimping device with upper and lower crimping guides registers its position with features on the truss hardware to insure that blind triple crimps are performed consistently each time.
