摘要: 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).
