Counterweight fixing device

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).

主权项

1. A counterweight fixing means for a crane having a counter jib, wherein the counterweight fixing means comprises a carrier bar, a connection of the carrier bar to the counter jib, and one or more counterweight blocks detachably hooked onto the carrier bar, and one or more plug-in pins, wherein
a) the carrier bar is arranged substantially at right angles to the longitudinal axis of the counter jib and horizontally, b) the connection of the carrier bar to the counter jib comprises two connecting struts arranged at right angles to the carrier bar, wherein the connecting struts lie parallel to one another, c) the counterweight fixing means comprises a transverse rail which is arranged parallel to the carrier bar, wherein the transverse rail comprises recesses for receiving at least one or more of the plug-in pins, and d) the counterweight blocks have substantially a U-shaped cross section, wherein the aperture in the U-shape allows the counterweight blocks to be hooked onto the carrier bar, and wherein each counterweight block has a narrow side which is directed toward the counter jib when the counterweight blocks are in the hooked-on state, and wherein the narrow side has recesses for receiving the plug-in pins.
