Abstract (en)

[origin: EP0849213A1] The maximum load for a rotary tower crane is stored as an extended limiting load curve in a memory module and a monitoring device acts to stop the crane operating when the load that is being carried reaches the extended limiting load curve. A controller is provided which allows only restricted operation of the crane between the limiting load curve and the extended limiting load curve, so that loads can only be moved at reduced speed and with reduced acceleration or deceleration. A switch is preferably provided to switch the crane operation to the extended load curve. One or more load curve limits can be provided in the increased carrying load area and a measuring device can report the position of the crane trolley.
