A modular crane, with a pot-shaped element on which an upper carriage of the crane can be mounted such that it can rotate about a rotational axis, multiple support carriers hinged to the pot-shaped element such that they can each pivot about a pivot axis for support on the ground, and a separable driving base on which the pot-shaped element can be secured.

Modular crane, transport unit for a modular crane and method for operating a crane of this type

A large mobile crane including an undercarriage. The undercarriage includes a middle section between tracks, wherein a distance between the tracks can be increased or decreased by the insertion or removal of expansion parts. The two tracks are connected on opposite sides of the undercarriage to permit movement of the large mobile crane. The undercarriage also includes a drive unit, a superstructure, one or more control stations, at least two main booms, at least one derrick boom, and at least two lifting devices and counterweights. The counterweights are either arranged separately of or mounted on the undercarriage. The large mobile crane further includes a circular track, and support rollers attached to the superstructure, wherein the support rollers ride on the circular track, and wherein the circular track is an integral part of the expansion parts.

Large mobile crane

The object of the invention is to reduce the amount of investment required for the usage-optimized configuration and installation of large cranes. This object is achieved by a large mobile crane having an undercarriage, a drive unit (), a revolving superstructure (), one or more control stations (), at least two jibs (), at least one counter-jib (), at least two lifting arrangements () and counterweights arranged separately or on the basic structure, characterized in that the load-bearing parts of the crane () and the mobility-specific parts () are of modular design and can be supplemented by exchangeable and/or supplementary parts, wherein the structural units (modules) used essentially correspond, or are similar, to existing standard-crane components, and an increase in load-bearing capacity can be achieved by arranging a number of these in the large crane.

A mobile crane includes an undercarriage with a middle section and two parallel crawler carriages; a superstructure on which a boom is mounted, the superstructure being connected to the undercarriage by a rotary joint; two longitudinal outriggers connected to the undercarriage and extending in the longitudinal direction between the crawler carriages; and two transverse outriggers connected to the undercarriage and extending outside the crawler carriages. One of the longitudinal outriggers has an end with a transverse beam supported by spaced apart outrigger cylinders which provide an extended tipping edge to further stabilize the crane.

Crane, in particular mobile crane with a narrow track and enlarged supporting base

A large mobile crane includes a revolving superstructure, a main boom hinged to the superstructure, and a derrick boom hinged to the superstructure. A modular counterweight system includes a traveling counterweight and a non-traveling counterweight connected to a crossbeam suspended from the distal end of the derrick boom so that the non-traveling counterweight is activated before the traveling counterweight.

Modular counterweight carriage for cranes, in particular for large crane

The invention relates to a bottom hook block system for a given maximum load, for providing differently portative bottom hook blocks for a crane, especially for a heavy lift crane. The bottom hook block system comprises four individual roller blocks () with a plurality of pulley blocks, two load hooks () and two intermediate links () by means of which two individual roller blocks (or) can be combined to a double roller block (). An equalizing link unit () consists of two equalizing links () that are interlinked via a joint support () with a vertical and at least one horizontal rotational axis. One of the equalizing links () is linked via a first horizontal hinge () with the two intermediate links (). The other equalizing link () is linked via at least one bearing block () with a second horizontal hinge () with the two load hooks (). The load hooks () can be swiveled about a vertical rotational axis in the respective bearing block (). A bearing connection () is provided in at least one of the intermediate links (), the connecting dimensions corresponding to the second horizontal hinge ().
