Abstract
Procedure for damping the sway of the load (2) moved by the carriage (1) of a crane, said load being suspended on at least one hoisting rope (3). The damping is achieved by using a discrete time control system whose control interval is varied in accordance with the hoisting rope length (L) while the control parameters remain constant.
