Crane

A rotary tower crane with a tower, which carries a jib and a counterjib, with a jib stay being guided from a tower top to the jib and to the counterjib. The jib stay tensions only an inner jib portion, the length of which is less than 40% of the total length of the jib, and an outer portion, the length of which is more than 60% of the total length of the jib, forms an untensioned bending beam jib which includes at least one jib piece which tapers in height and which is adjoined on the inner side by at least one jib part of greater height and on the outer side by a jib piece of smaller height.

Rotary tower crane

The invention relates to a tower crane with a crane tower and a jib mounted thereon as well as a counter-jib, wherein the length of the counter-jib is defined by the number of the counterweights received.

Tower crane

The invention relates to a tower crane comprising a tower of at least one tower element, in particular a lattice piece, and a structural guying device having at least one guying rod for the horizontal anchorage of the tower at a structure. In accordance with the invention, the tower has a vertically adjustable guide frame, wherein at least one positioning rope is adjustably fastened to the guide frame. The invention furthermore relates to a method of mounting a wind turbine rotor blade.
