Advanced rotational control

08.03.2017
mapp Crane
mapp Crane actively controls rotation about the vertical axis to prevent skew oscillation.

New software package suppresses skew oscillation

B&R has introduced a new function for crane control. Cranes that transport payloads suspended from sling systems can be particularly sensitive to rotation about the vertical axis. If left unchecked, this can lead to uncontrollable sustained oscillations. The new mapp Crane solution successfully damps this effect.

Fast and safe payload delivery

It is also possible to execute a controlled rotation, which can be helpful in cases where a payload needs to be positioned at a specific angle. With simultaneous control of both skew and sway, payloads can be brought to their destination with maximum speed and precision.

Automatic path correction

mapp Crane also offers automatic path correction, which adjusts for changes to the end position while the crane is in motion. This is an especially challenging task with regard to path planning, because the recalculations must account for the system's oscillation dynamics in addition to its axis boundaries. With mapp Crane, this function can now be implemented with very little programming.
