Abstract (en)
A method for controlling a crane (2) comprising a jib (4) having a crane tip (16) and a hoist (6) comprising a load connection structure (28), wherein the crane (2) configured to carry a load (14) and comprises:- one or more of jib actuators (8) arranged to activate the jib (4);- one or more hoist actuators (10) arranged to activate the hoist (6);- a control unit (12) configured control the one or more jib actuators (8) and the one or more hoist actuators (10) configured to change the distance (D) between the load connection structure (28) and the crane tip (16). The method comprises the step of providing a command (C<sub>A</sub>, C<sub>B</sub>) to the control unit (12) to activate the one or more jib actuators (8). The method comprises the following steps:- determining the change (ΔD<sub>jib</sub>) of the distance (D) between the load connection structure (28) and the crane tip (16) caused by motion of the jib (4) when executing the command (C<sub>A</sub>, C<sub>B</sub>);- determining a correcting signal (C<sub>S</sub>) suitable for at least partly counteracting the change (ΔD<sub>jib</sub>) of the distance (D) between the load connection structure (28) and the crane tip (16);- activating the one or more hoist actuators (10) by using the determined correcting signal (C<sub>S</sub>).
