Using sway control

Only with sway control

The “Sway control” function considerably reduces the swinging movement of the load hook during trolley and crane travel on a crane with ABUControl. See the “ABUControl” product manual.

 

See the ABURemote product manual.

The sway control initially functions only with a crane with a single trolley or with a crane with several trolleys, providing the unused trolley is in the parking position.
During the joint operation of several trolleys or in tandem operation, the sway control must be separately enabled. See the ABUControl Product Manual.

For ABURemote with individual control: If a load hook is in the highest hook position (top hoist limiter), the sway control can be switched on for the other load hook.

 

 

   Operate the crane as usual.

●   ABUControl uses the travel speeds of crane and trolley, the hook position and the length of the load lifting attachment to calculate how much the load would normally sway, and accelerates and brakes the travel motors in such a way that the swinging movement is reduced.

●   The acceleration and braking distances are not substantially altered.

●   The function does not compensate for external influences such as wind, impacts against the load or load hook, or manual movements.

 

 

Instructions for sway control for multiple trolleys:

The calculation of the sway control only functions correctly in joint operation of multiple trolleys or in tandem operation if the crane operator observes these conditions:

─     Crane and trolley must be the same type and size.

─     The load must be slung correctly:

Hook position
Length of the lifting tackle	Uniform load

A uniform collective load must be slung so that the hook position and the length of the lifting tackle added together results in the same total length in each case.

 

 

Hook position
Length of the lifting tackle	Distance to centre of gravity

An uneven collective load must be slung so that the hook position, the length of the lifting tackle and the distance to the centre of gravity added together results in the same total length in each case.

─     The length of the lifting tackle must be entered:

In joint operation of multiple trolleys, the length of the lifting tackle for trolley 1 must be entered.

In tandem operation, the length of the lifting tackle from the first crane must be entered. The first crane has the IP address 192.168.1.1
