ABSTRACT:
A new trellis support structure and a method for its production for use in supporting vine borne crops. The support structure includes a metallic support member that is bent into a modified U-shape and attached to a metallic cross arm using a process that produces consistent results. The combination of the U-shaped member and cross arm is then attached to a vertical support post at two different locations: one attachment at the center of the U-shaped member, and the other attachment at the center of the cross arm in an axial alignment with the support post. The structure is extremely strong, capable of supporting considerable weight, not likely to shift, and less prone to failure from fatigue. The support structure is produced by first bending the central section of a metallic support member into a U-shape, placing the bent member on a specially designed adjustable jig, and attaching a cross arm. This assembly is then attached to a support post in two places preventing pivotal rotation of the combined structure once it is mounted to the support post.
