Estimating the term…
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 (16), a revolving superstructure (18), one or more control stations (17), at least two jibs (3), at least one counter-jib (4), at least two lifting arrangements (22) and counterwvejghts arranged separately or on the basic structure, characterized in that the load-bearing parts of the crane (3, 4, 20) and the mobility-specific parts (5, 6, 7) 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.
Large mobile crane with an undercarriage, 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, either separate or mounted on the basic machine, wherein the at least two main booms and the at least one derrick boom comprise modules supplemented with expansion parts, where the modules used essentially correspond to standard crane components, and where multiple modules are combinable to form a large crane with a greater working load capacity.
