Le pont (3) du pont-grue ou de la grue-portique est constitué d'un bâti composé de traverses de tête et de poutres maîtresses, un chariot (4) pourvu d'un mécanisme de levage (5) pouvant être déplacé sur ledit pont. Selon l'invention, le pont (3) comporte un côté appui fixe (7) ainsi qu'un côté appui libre (8) pour les roues de rail (12.2) qui sont destinées à être déplacées sur les rails (2.3 ; 2.4) de la voie de roulement de grue (2), au niveau des quatre coins du pont (3). Cette invention est caractérisée : en ce qu'un balancier (12.1) comprenant au moins deux roues de rail (12.2) déplaçables sur lesdits rails (2.3 ; 2.4) est disposé au niveau de chacun des quatre coins du pont (3) ; en ce que les balanciers (12.1) sont montés de manière articulée autour d'un axe horizontal (Y) orienté transversalement à la direction de déplacement du pont (3) et d'un axe (Z) orienté verticalement à celui-ci ; et en ce que les balanciers (12.1) disposés côté appui libre (8) peuvent en outre pivoter autour d'un axe horizontal (X) orienté dans la direction de déplacement du pont (3).
