Qi Gong super conditions for a crane and a crane control system

The present invention discloses a control system for a crane and a crane for ultra condition Qi Gong, relates to the field of mechanical engineering. To solve the technical problem of poor security of existing technology, reliability. The control system for a crane over Qi Gong conditions, including superlift counterweight moving means, detecting means, controllers, human-machine interaction means and an alarm controller according to the calculated rate of work superlift counterweight, super luffing force of the main counterweight parameter Qi Gong crane operation parameters and calculated in real time the value of the rated load of the crane and the crane at least one security value; main luffing winch controller is further configured to detect the crane bear security amplitude value of the main force of the main luffing crane or force is greater than the detected actual load of the crane is greater than the rated load value of a crane, or the alarm by the alarm means through human-machine interaction. The present invention is for improving the safety and reliability of the crane.
