Title (EN) A HEAVY-DUTY FORE-AND-AFT WORKING SHIP'S CRANE
(FR) GRUE DE BATEAU AVANT-ARRIERE DE GRANDE PUISSANCE
Abstract: front page image
(EN)The primary jib (9) of the crane is supported, at its upper end (10), by first and second jib control lines (17 and 19) extending to the upper end (10) of the primary jib (9) from first and second parts (6 and 7) of a cross-member (5) extending laterally of a supporting mast (3). The first jib control line (16) also extends from the upper end (10) of the primary jib (9) to a base (1). The second jib control line (18) has no such extension. Adequate support is provided because the second part (7) is spaced further than the first part (6) from an intermediate reference point (8) cross-member (5) disposed above the pivotally supported lower end (11) of the primary jib (9). The first part (6) of the cross-member (5) and said reference point (8) are disposed on the same side of the mast (3) and so the primary jib (9) can be swung around the mast (3).
(FR)La premiere fleche (9) de la grue est supportee, a son extremite superieure (10), par une premiere et une seconde lignes de commande de la fleche (17 et 19) s'etendant jusqu'a l'extremite superieure (10) de la premiere fleche (9) a partir de la premiere et seconde parties (6 et 7) d'un organe transversal (5) s'etendant lateralement par rapport a un mat de support (3). La premiere ligne de commande de la fleche (16) s'etend egalement a partir de l'extremite superieure (10) de la premiere fleche (9) jusqu'a une embase (1). La seconde ligne de commande de la fleche (18) ne possede pas cette extension. Un support adequat est prevu parce que la seconde partie (7) est plus ecartee que la premiere partie (6) d'un point de reference intermediaire (8) de l'organe transversal (5) dispose au-dessus de l'extremite inferieure pivotante (11) de la premiere fleche (9). La premiere partie (6) de l'organe transversal (5) et ledit point de reference (8) sont disposes du meme cote du mat (3) de sorte que la premiere fleche (9) puisse pivoter autour du mat (3).
