Abstract

Appareil de levage (1) comportant un premier réa fixe (7) de renvoi, un réa mobile (8, 13) de renvoi présentant un point de fixation (8’’), un deuxième réa fixe (9, 14) de renvoi. Un filin (3) dont l’une de ses extrémités (5) est agencée pour recevoir un crochet (6) pour recevoir une charge, passe successivement par le premier réa fixe, par le réa mobile, par le deuxième réa fixe. Selon l’invention, l’appareil de levage présente un dispositif de verrouillage (10) présentant une position de déverrouillage dans laquelle le réa mobile est mobile, une position de verrouillage dans laquelle le réa mobile est fixe. Figure 1Lifting device (1) comprising a first fixed sheave (7) of return, a movable sheave (8, 13) of return having an attachment point (8 ’’), a second fixed sheave (9, 14) of return. A rope (3), one of its ends (5) of which is arranged to receive a hook (6) to receive a load, passes successively through the first fixed sheave, through the mobile sheave, through the second fixed sheave. According to the invention, the lifting device has a locking device (10) having an unlocking position in which the mobile sheave is mobile, a locking position in which the mobile sheave is fixed.
