Abstract

En anordning for tilsetting og frigjøring av gjengede brønnrørkoplInger bar en stasjonar støtte (7,8) Bonterbar på et rlggulv (1) og poslsjonerlngsamer (14.10) montert på den stasjonere støtte. Poslsjon- erlngsaraene selektivt støtter og posisjonerer en bevegbar ramme (32) som bxrer motortenger (30) for klemmlng av rørseksjoner. Ved opererlng av poslsjon- erlngsarmene blir motortengene operativt plassert til å virke på et rer ved brønnsenteret (6), plassert 1 bortstuvet stilling eller plassert i en musetaullposl- sjon (6) for å virke på et rør i musehullet.
