Abstract (en)
The bracing has a set of supporting elements (7) arranged laterally on a lattice boom (1) of a crane, and connection elements connecting the supporting elements with each other in a longitudinal direction of the boom. A clamping unit (14) i.e. hydraulic cylinder, introduces a tensile stress into the connection elements. The supporting elements are removably connected with sides of the lattice boom. The supporting elements have three longitudinal rods (3) in the form of a triangle whose base side is bolted laterally with the boom and leading edges are connected with the connection elements. Independent claims are also included for the following: (1) a connecting piece for connecting a bolt with a lateral bracing (2) a crane (3) a method for operating a crane (4) a crane control software stored on a data carrier or a data storage for performing a method for operating a crane.
