Abstract: front page image
(EN)A hoisting accessory to be connected to a hoisting device for facilitating the placing of a load through openings in walls and the like. Said accessory has a support arm (10), at one end of which a load coupling unit (11) is provided for carrying a load. At its other end the support arm (10) has a counterweight means (20) including a suspension unit (22) extending downwards from support arm and along which a movable unit (23) is displaceable under action of gravity from a retracted position to an extended position. Between the ends of the support arm (10) there is a lift yoke (30) for connection to said hoisting device. A releasable locking device (50) prevents the movable unit (23) from moving. An actuation means (19, 15; 63) is provided to release said locking device in response to charging of the load coupling unit (11). In a preferred embodiment said actuation means is adjustable.

Cet accessoire possede un bras de support (10) a une extremite duquel un dispositif d"accouplement de charge (11) est monte pour porter une charge. A son autre extremite le bras de support (10) possede un contrepoids (20) comprenant un dispositif de suspension (22) s"etendant vers le bas a partir du bras de support et le long duquel un dispositif mobile (23) peut se deplacer par gravite depuis une position retractee jusqu"a une position detendue. Entre les extremites du bras de support (10) se trouve un etrier de levage (30) de rattachement avec le dispositif de hissage. Un dispositif de verrouillage liberable (50) empeche le dispositif mobile (23) de bouger. Des moyens (19, 15; 63) sont prevus pour liberer ce dispositif de verrouillage en reponse au chargement du dispositif d"accouplement de charge (11). Dans un mode preferentiel de realisation lesdits moyens d"actionnement sont reglables.
