Abstract

Ballast weight (12) for coupling to an attachment means (11), in particular to a hook, attached to the lower end of a rope (10) of a crane (9),wherein the ballast weight (12) is formed by or comprises a main body (17),wherein the main body (17) encompasses a receiving space (18),wherein the receiving space (18) is designed to receive at least a section of the attachment means (11) in an operational state (78) of the ballast weight (12),wherein the receiving space (18) is delimited by an inner surface (21) of the main body (17) and extends along a central axis (19) of the ballast weight (12),wherein the size (74, 75) of the receiving space (18) in at least one direction orthogonal to the central axis (19) is larger at a first position (76) along the central axis (19) than at a second position (77) along the central axis (19) that is arranged above the first position (76), such that the inner surface (21) forms a contact surface (41) arranged at an angle (80) to the central axis (19), that is designed to be supported by a support surface (42) of the attachment means (11),wherein the main body (17) comprises a slit (20) to allow for a movement of the rope (10) into the receiving space (18). Also disclosed is a crane system comprising such a ballast weight and a rack for storing a ballast weight and a method of operating a wind turbine wherein the turbine is constructed using such a crane.
