Abstract (en)
[origin: US6516961B1] A ringlift crane having a ring which can be elevated, forms an annular track and has a plurality of segments which can be connected to one another, there being arranged within said ring an undercarriage which has an upper carriage, which is connected for slewing action to the undercarriage and has a plurality of hoisting winches. Two trusses which are spaced apart parallel to one another, are provided, in two mutually opposite end regions, with in each case one adapter and can be bolted to, and unbolted from, the upper carriage via crossmembers. The adapters are supported with rolling action on the annular track of the ring by rollers arranged in the end region of the adapters. For the purpose of setting different modes of operation of the crane, the trusses can be raised relative to the basic machine and connected in different ways to the crossmembers.
