Abstract

La présente invention concerne un système et un procédé permettant de tendre des armatures de précontrainte. Le système selon l'invention comprend un dispositif de traction hydraulique conçu pour exercer un effort de traction sur une armature de précontrainte s'étendant depuis une structure, et une entrée utilisateur conçue pour recevoir un paramètre de mise en tension désiré par l'utilisateur, ledit paramètre indiquant une amplitude de mise en tension désirée et/ou une distance de mise en tension désirée. Le système comporte également un processeur configuré pour recevoir le paramètre de mise en tension désiré par l'utilisateur de l'entrée utilisateur, et pour commander le dispositif de traction hydraulique pour qu'il applique au moins l'amplitude de mise en tension désirée et/ou la distance de mise en tension désirée sur l'armature de précontrainte.
