Abstract

In a process to dampen the pendulum motion of a crane load consisting of bulk aggregate solids, a regulator sets a value for the motor power output setting the load in motion. The value initiates the motion along a predetermined time-optimised trajectory. This trajectory is determined by an oscillation model relating to the aggregate solid load, from a starting point within the load take-up point towards a predetermined discharge point. The load is discharged while still in motion over the release point. Further claimed are a control program and an automated crane system.
