1. A combination comprising a crane and a load guiding arrangement arranged for mounting to the crane, which crane comprises a crane boom and which load guiding arrangement is arranged for controlling the orientation of a load suspended in a crane boom from a bearing wire about the bearing wire, which combination comprises:
two winches, each of the winches has a bi-directional rotational spool, wherein the winches are placed on the crane;
two taglines with a first end of the tagline attached to the spool, wherein each tagline is connected to the load for applying a controlled torque to the load about the bearing wire;
two attachment brackets attached to the crane boom in an attachment position in a top zone of the crane boom, each attachment bracket is arranged for attachment to a second end of the tagline; and
two tagline redirection devices,
wherein the redirection devices allow the tagline to roll or slide around the redirection devices while the load is raised or lowered and simultaneously provides for a redirection of the tagline, whereby
each tagline is connected with the load through the redirection devices so that each tagline extend from the spool to the attachment bracket via the redirection devices, wherein the combination furthermore comprises:
a crane counterweight; and
for each winch, a winch frame, which is mounted directly on the crane next to or on the crane counterweight in positions at each side of the crane,
wherein each winch frame is configured with a form corresponding the form of counterweight blocks and is attached to the crane counterweight in a position between the counterweight blocks.
