The present disclosure relates to a telescopic boom for a crane, wherein the telescopic sections of the telescopic boom each comprise at least one main telescopic part and at least one additional telescopic part and wherein the main telescopic part and the additional telescopic part are arranged above one another. The disclosure further relates to a crane having a corresponding telescopic boom.

Telescopic boom for a crane and crane having a corresponding telescopic boom

The present disclosure relates to a support for a crane, in particular for a mobile crane, having at least two first support beams and two second support beams that are each arranged pairwise at mutually oppositely disposed sides of the support.

Support for a crane

The present invention relates to a telescopic sliding beam for supporting a work machine comprising a sliding beam box and an internal sliding beam that is outwardly telescopically supported in the sliding beam box. The sliding beam box and the internal sliding beam have an opening in the peripheral region, with the openings overlapping one another in an outwardly telescoped state, and with a bolt being able to be introduced into the overlapping openings. The sliding beam box has an abutment at its inner side and the internal sliding beam has an abutment at its outer side, with the abutment of the sliding beam box and the abutment of the internal sliding beam contacting one another in an outwardly telescoped state such that a further pulling of the internal sliding beam out of the sliding beam box is suppressed. The invention furthermore comprises a work machine comprising this telescopic sliding beam.

Sliding beam for supporting a work machine

The invention relates to a process for the calculation of relevant data for the operation of at least one crane, particularly of a mobile crane, whereby the system comprises at least one crane, a communication network, as well as a data processing center, whereby, first of all, one or more parameters of the crane are determined on the crane and these are transmitted to the data processing center through the communication network and, in the data processing center, one or more items of data that are relevant for the operation of the crane are computed and/or selected on the basis of the one or more parameters received from the crane and the relevant data computed and/or selected for the operation of the crane is transmitted back to the at least one crane, particularly to its crane control. Furthermore, the invention relates to a system for the calculation and/or selection of data relevant to the operation of at least one crane that is suitable for the implementation of the process in accordance with the invention.
