Embodiment Construction

[0227] Figure 1a An embodiment of a crane 1 according to the invention is shown schematically.

[0228] Figure 1a The crane 1 in includes a crane base 2 . The crane base 2 may be, for example, the chassis of a crawler crane, and / or the bottom assembly of, for example, a ring crane. The crane base 2 is arranged on a support surface 3 of the work area. The crane bed 2 is pivotable about a substantially vertical crane bed pivot axis (not shown).

[0229] The crane according to the invention has a first mast 10, at Figure 1a In the embodiment, the first mast 10 includes a plurality of mast sections 11 . In this embodiment there is a top mast section 12 , a number of intermediate mast sections 13 and a lower mast section 14 . It can be seen that the lower mast section 14 tapers in the direction of the crane base 2 .

[0230] The first mast 10 has a central axis 15 extending in the longitudinal direction of the first mast 10 . The first mast 10 is tiltable relative to the cr...

Abstract

Method for assembling and disassembling a crane (1) comprising a first tiliable mast (10) relative to the crane base (2) around a first mast pivot axis (16) into an inclined mast operating position and a receiving device (30), which is adapted to receive the mast section of the first mast.

Description

technical field [0001] The present invention relates to the field of hoisting cranes and hoisting equipment, in particular to large-scale cranes of modular design, wherein the crane is transported in a disassembled state to a place where lifting operations are to be performed, and then assembled. Background technique [0002] On site, a large lattice jib crane is used, which is assembled at the operating site. Typically, the main boom and / or mizzen mast of a crane are assembled while on the ground and then hoisted and / or pulled up into their operating position. A very common problem is that, for example, when new reactor vessels are to be installed in existing petrochemical plants, there is limited space available on site for the installation of cranes. [0003] Several solutions to this problem have been proposed. [0004] For example, EP3301064 describes a device for lifting heavy loads. In this arrangement a ground standing erection facility is provided which allows th...
