    摘要: The invention relates to an electro-hydraulic device for moving a jib for a derricking-jib tower crane, the motor of said device being designed for operation at the average required power. The operating time in an energy-wasting part load range is thus significantly reduced in relation to conventional electro-hydraulic devices for moving a jib.

    摘要: The invention relates to a jib-bracing system for a revolving tower crane, in the case of which the length of a jib (2) and the length of a bracing means (5) for the jib can each be changed. The bracing means comprises at least part of a cable (6) of which one end can be connected to the jib at at least two different fixed points (8, 9) arranged on the jib, wherein a deflecting element (7), over which the cable can be guided, is arranged on the jib, and wherein the one end of the cable can be fastened at at least one of the fixed points when the cable has been guided over the deflecting element.

    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).
