Abstract
En traktoranordning for nedihulls hydrokarbonapplikasjoner som anvender flere traktorer samtidig. Anordningen drives hydraulisk og kan tilveiebringe en betydelig økning i den totale last som tas opp via nedihulls traktorkjøring. Kveilrørsoperasjoner kan således kjøres på store brønndybder. I tillegg kan den last som tas opp av anordningen balanseres hydraulisk mellom de flere traktorer i anordningen gjennom et mangfold av teknikker. På denne måte kan den totale last som tas opp forbedres, og slitasje på den opphulls traktor i anordningen reduseres.
