Pivot Systems

Pivot Systems Ask for information

Pivot (or bolted-line system) and ranger (or shifting-line system).
Recently, irrigation systems with large shifting lines have gained much currency, especially due to the presence of medium-sized and large fields with extensive cultivation of maize, soy and industrial crops such as potatoes, tomatoes and sweet corn (although these systems are adaptable and thus compatible with fields of just 4-5 hectares). 
The term "pivot" is used to indicate those systems that revolve around a central pyramidal column attached with one or more spans to electrically driven carriages. In these systems, the irrigated surface has a round shape; water infeed and electrical control panels are located in the central column. 
The term "ranger" (or "linear pivot") refers to those systems in which both ends of each span rest on electrically driven carriages. In these systems, the irrigated surface has a rectangular shape; water is fed via ducts or pipes that run parallel to the unit's movement. Once they have reached the end of the track, some systems are able to rotate by 180°, thereby doubling the irrigated surface (trotting arenas). 
These systems are controlled via electrical control panels, which check that the system is working properly, program start and stop and regulate water distribution on a zone-by-zone basis. Moreover, in the most advanced systems, they can be controlled via GSM network and can be connected to GPS localisation systems. 
Water is distributed through static low-pressure sprayers, which, in addition to reducing energy costs thanks to their lower working pressure, prevent the generation of mist-spraying which could result in a loss of performance due to wind and evaporation. 
The use of these systems offers benefits both in economic  terms (low energy and water consumption, 90% of water distribution efficiency), and in agronomic terms:  • regular and controlled interventions preserve the water balance of the soil;  • since instant water distribution is low, water adsorption is facilitated even in uneven terrains, which remain softer and more drained; this also helps avoid run-off and deep percolation;  • the water does not expose crops to any thermal shock;  • thanks to fertirrigation, fertilisation can be made more effective  In addition to providing the necessary materials and installation recommendations, Irrigazione Veneta can supply suitable equipment and personnel for laying the system
