Irrigation systems with central pivot, irrigate large surfaces of circular shape. These are generally used in fields where we want to increase irrigation efficiency, having a more efficient use of water and increasing crop yields. The efficiency with pivot irrigation is between 85% – 90%.

This system adapts to uneven terrains. They can be used in areas with up to 30% slope.

Water distribution along the structure can be adjusted by selecting the size and spacing of the nozzles. Sprinklers located near the center of the pivot need to deliver less water than those located close to the end. With the new technology in sprinkler for pivots, designers have managed to lower the operating pressure of the sprinklers (up 6-10psi = 0,42-0,7bar); and thus, the operating pressure of the pivots (and power consumption).

Crops generally irrigated with central pivot systems are corn, soybeans, wheat, cotton, peanuts, potatoes, sunflower, Lucernes, sorghum, sugar beet, vegetables, natural pastures, etc. There are also facilities where sprinklers have been replaced by dripper lines, allowing water drip some crops, but at a lower installation cost.

The pivots can be operated by simple boards or up to complex computer systems with communication by telephone or radio. In this case, the pivot may, for example, be operated depending on the soil moisture or weather conditions.

The union between spans by ball joint allows the absortion of large slopes, both transversely (20%), and longitudinally (15%).

The ball joint allows the rotation of a span respect the next one when a pivot tower is climbing a slope while the other ones are going down.

Span towers designed to withstand the stress generated by the hills and grooves of the crop. The towers are formed by four angles 75x75x8mm standard profile. Ladders on both sides and diagonals reinforcing pipes. Compression pipes stabilize both the span and the tower in extreme terrain conditions.
