The invention relates to a lifting weight limiting device capable of automatically recognizing hoisting fixtures and setting the lifting weight limiting parameters according to the adopted hoisting fixtures. The lifting weight limiting device is applied to overload limiting of a crane using various hoisting fixtures. The lifting weight limiting device comprises a measurement control device 1, hoisting fixture recognizing information generation devices 3 and a load sensor 5. A data storage unit is arranged inside the measurement control device 1. The measurement control device 1 is connected with a crane control system 4 through a control output interface 2 and is used for giving out overload signals to the crane control system 4 when overloading happens. The hoisting fixtures of the crane are each provided with one hoisting fixture recognizing information generation device 3, and the signal types of the hoisting fixture recognizing information generation devices 3 can be either digital quantity or analog quantity. The measurement control device 1 can recognize the hoisting fixtures by reading the information, so that the load limiting parameters matched with the hoisting fixtures are loaded automatically. Accordingly, the lifting weight limiting device has the lifting weight limiting function on different hoisting fixtures, instead of the total lifting weight limiting function on the crane singly, and accidents caused by overloading of the hoisting fixtures can be avoided.
