Abstract: front page image
(EN)A steel cable pre-tension device comprising: a pre-tension reel (1) for winding and keeping a steel cable (51); also a breaking system (2) connected to the pre-tension reel and applies pre-tension torque to same. The device enables a pre-tension force to be provided to the steel cable that is about to be wind onto the reel of a lifting mechanism, thereby preventing the steel cable from entanglement and extending the service life thereof.
(FR)L'invention porte sur un dispositif de pré-tension de câble en acier, lequel dispositif comprend : un rouleau de pré-tension (1) pour enrouler et maintenir un câble en acier (51); ainsi qu'un système de freinage (2) relié au rouleau de pré-tension et appliquant un couple de pré-tension à celui-ci. Le dispositif permet de fournir une force de pré-tension au câble en acier qui est sur le point d'être enroulé sur le rouleau d'un mécanisme de levage, de façon à empêcher ainsi le câble en acier d'être emmêlé, et de prolonger ainsi la durée de vie de celui-ci.
