Central Irrigation pivot

The pivot is a mechanised irrigation system that irrigates in a circular manner (full rotation)
or in sections. It generally moves around a fixed central point but it can be designed to be towed from one pivot point to another or from one field to another.

The pivot system has a number of spans consisting of a tube supported by a truss and a motorised tower that move around a central unit, which acts as an intake for the water and electricity supply.
