22 Center Pivot 7000, 8000, 8120 Series
OVERVIEW
Spans
Water is transported to the irrigation machine through an underground pipe line. The water is then transported
across the field through a pipeline. The pipeline is made up of a series of spans which are connected together.
Each span also consists of a drive tower which moves the pipeline across the field. See Figure 22-1.
A span consists of a water pipeline supported with a bowstring under truss design. Truss rods are attached to
each truss assembly to support and strengthen the pipeline. See Figure 22-1.
The spans are attached to each other with a ball hitch and cup assembly which gives lateral, rotational, and
vertical flexibility between the spans. See Figure 22-2.
The pipelines in each span are connected together with a flexible hose that is held in place with band clamps.
See Figure 22-2.
