Anti-Sway: Controlling the Swaying of the Load

Anti-sway systems come under three main categories:

• Passive systems, where cables attached to the load prevent it from swaying


• Active closed-loop systems, where the swaying angle is measured with a camera connected to an image processing system
• Active open-loop systems, where the information is obtained without additional sensors from the information available

Handling loads is an essential operation in all human activity. Moving and transporting objects is part of the daily life of anybody who is in the industrial sector.

In the manufacturing and distribution sectors, this operation is very often done using handling equipment, such as overhead travelling cranes or gantry cranes controlled by hoist operators and it is not uncommon for load-moving to take up 20% of the production cycle.

Thus, load-moving often determines the consistency of the production cycle. In order to limit fragmentation of the cycle, it is therefore vital that these handling periods are:

• as short as possible,


• as consistent as possible.
Which cannot happen without a device to help to control the swaying of the load.

OEM's which offer this device have an undoubted competitive advantage.
