Counterweight fixing device (1) for a crane, which is comparatively easy to install and can also be used in particular for cranes with a derricking jib, in which the derricking jib is rigidly connected to the mast (3), and at the same time provides a safe design without generating a high noise level during operation. The core principle of the design of the counterweight fixing device (1) is that the counterweight blocks (4) are simply suspended on a carrier bar (2), but the generation of noise is kept to a low level due to the suppression of the freedom of movement of the counterweight blocks (4).

    L'invention concerne une fixation de contre-poids (1) pour une grue, pouvant être relativement facile à monter et être utilisée également pour des grues à flèche relevable dans lesquelles la flèche relevable est reliée rigidement à la contre-flèche (3). Ainsi, cette fixation de contre-poids (1) permet d'obtenir une construction sure sans développement de bruit important lors de son fonctionnement. La fixation de contre-poids (1) est caractérisée en ce que les blocs de contrepoids (4) sont suspendus de manière simple à une tige de support (2), le développement de bruit étant maintenu à un faible niveau en raison de la suppression de la liberté de mouvement des blocs de contrepoids (4).
