Abstract
Counterweight fixing device () 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 (), 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 () is that the counterweight blocks () are simply suspended on a carrier bar (), but the generation of noise is kept to a low level due to the suppression of the freedom of movement of the counterweight blocks ().
