Our pendulum damping (PendDamp) is a module for actively preventing (damping) pendulum movements by directly intervening in the control of the crane and trolley drives of indoor cranes. It extends our CranePilot, but can also be used without it.
As an example, the video shows the travel movement carried out after a strong pendulum motion was manually applied – our pendulum damping (PendDamp) was active when the level movement started.
The following information must be made available to our PendDamp in quasi-real time with a sufficiently high sampling rate as sensor-based variables:
Our special sensor technology records the current pendulum situation, with two possible options to choose from:
The above-mentioned information is used to calculate and forward in real time appropriately adapted acceleration specifications to avoid or dampen excessive swaying movements for controlling the level axis drives.
