The invention discloses a crane load limiter and a configuration method and device.The crane load limiter comprises a balance pulley, a steel wire rope, an eccentric shaft, a working spring and a load sensor, and the diameter of the balance pulley is determined according to the diameter of the steel wire rope; the diameter of the eccentric shaft is determined according to the stress of the steel wire rope under the rated hoisting working condition, the supporting span of the balance pulley under the rated hoisting working condition and the allowable stress of the eccentric shaft under the rated hoisting working condition, and the parameters of the load sensor are determined according to the maximum measuring force calculated according to the rated hoisting working condition of the crane. The mechanical parameters of the working spring are determined according to the rated working condition, the no-load working condition and the rope loosening working condition of the crane. The actual load is converted through the eccentric shaft, the measured value of the load sensor is converted into the actual value according to the design method, the working range of the load sensor is effectively reduced, and large load monitoring is achieved without specially customizing the sensor.
