r 1 IL Z2 à Schec und Liobo, H&e i-'ktige6µ3-ls-b Giue avec balance automatique, poiron'able et à flèche relevable sous charge.
Jusqu'à présent il fut impossible de munir les grues à volée variable et chemin du crochet approximativement horizontale d'une balance poinponnable. Tout au plus on était parvenu à obtenir une seule position de la volée ou 1 'on pouvait garantir un poids absolument juste. La con-
EMI1.2
' dition cherchée, à laquelle on peut peser et poinponrner la balance à chaque position de la volée, est d'obtenir qu'une longeur d'environ 2 n du câble de levage, avant d' arriver du tambour à la poulie', de tête, reste constamment horizontale, pendant toute la manoeuvre du relevage de la volée.
Le dessin annexe, donné à titre d'exemple, montre urne forme d'exécution de' ce genre de grue.- .
Pratiquement cette condition a été remplie par le loge- ment de deux poulies 3 et 4 dans une charpente 1, arti-

EMI1.1
r 1 IL Z2 à Schec und Liobo, H & e i-'ktige6µ3-ls-b Giue with automatic scale, poiron'able and lifting boom under load.
Until now, it has been impossible to equip cranes with variable boom and approximately horizontal hook path with a punching scale. At most, one had succeeded in obtaining a single position of the volley where an absolutely fair weight could be guaranteed. The con-
EMI1.2
'desired edition, at which the balance can be weighed and punched at each position of the flight, is to obtain that a length of approximately 2 n of the lifting cable, before arriving from the drum to the pulley', to head, remains constantly horizontal, throughout the lifting maneuver of the flight.
The accompanying drawing, given by way of example, shows an embodiment of this kind of crane.
Practically this condition has been fulfilled by the accommodation of two pulleys 3 and 4 in a frame 1, arti-
