The invention discloses a control system for a super lifting working condition of a crane and the crane, relates to the technical field of engineering machinery, and solves the technical problems of poorer safety and reliability in the prior art. The control system for the super lifting working condition of the crane includes a super lifting counterweight mobile device, a detection device, a controller, a man-machine interaction device and an alarm; the controller is used for real-timely calculating out at least one of a rated load value of the crane and a safety value of a main luffing force of the crane according to a calculated super lifting counterweight working range, super lifting working condition parameters and crane counterweight parameters; the controller is also used for alarming through the alarm or the man-machine interaction device when a detected main luffing force supported by a main luffing winch of the crane is greater than the safety value of the main luffing force of the crane or when a detected actual load value of the crane is greater than the rated load value of the crane. The control system is used for improving the safety and the reliability of the crane.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control system for a crane in super-lifting working condition and a crane provided with the control system for crane super-lifting working condition. Background technique [0002] At present, the scope of application of large-tonnage cranes is becoming more and more extensive. In order to increase the lifting performance of medium and large tonnage cranes, superlift mechanisms and superlift counterweights (or superlift counterweights) are generally added to the cranes. [0003] The super-lifting mechanism is a device that improves the stress status of the components and the stability of the whole machine, and improves the lifting performance of the crane by adding a super-lifting mast, a super-lifting counterweight and a super-lifting counterweight moving device. One end of the superlift mast is hinged with the turntable, and the other end is connected with the m...
