Operating method for a crane installation, in particular for a container crane

An operating method for a crane installation, in particular for a container crane, with a trolley for transporting a load, said method comprising:

• determining loading of the trolley based on the load to be transported;
• and
• controlling travel movements of the trolley with a travel drive connected to the trolley and a trolley controller connected to the travel drive, wherein the travel movements comprise acceleration operations and braking operations during the travel movements of the trolley as a function of the loading of the trolley and a maximum available drive force of the travel drive,
• wherein at least one of the acceleration operations comprises two sections having positive acceleration values of equal magnitude and an intermediate section having a negative acceleration value of a magnitude equal to the magnitude of the positive acceleration values, and
• wherein at least one of the braking operations comprises two sections having negative acceleration values of equal magnitude and an intermediate section having a positive acceleration value of a magnitude equal to the magnitude of the negative acceleration values.

A computer program stored on a machine-readable con-transitory storage medium and comprising machine code, wherein the machine code, when loaded into a memory of a trolley controller and executed by the trolley controller, causes the trolley controller to

• receive loading of a trolley controlled by the trolley controller, and
• control acceleration operations and braking operations during a travel movement of the trolley as a function of the loading of the trolley and a maximum available drive force of the travel drive,
• wherein at least one of the acceleration operations comprises two sections having positive acceleration values of equal magnitude and an intermediate section having a negative acceleration value of a magnitude equal to the magnitude of the positive acceleration values, and
• wherein at least one of the braking operations comprises two sections having negative acceleration values of equal magnitude and an intermediate section having a positive acceleration value of a magnitude equal to the magnitude of the negative acceleration values.
