The invention discloses an automatic speed finding control system of a crane. A detection unit comprises a sensor, detects real-time hoisting weight of the crane and transmits an analog signal to an information arithmetical processing unit; the information arithmetical processing unit processes the analog signal transmitted by the detection unit and outputs a corresponding digital value signal to a control core; the control core is a PLC (programmable logic controller) singlechip, processes and computes the received digital value signal and controls frequency output of an execution unit via a preset speed frequency corresponding to rated hoisting weight to achieve the purpose of controlling operating speed; the execution unit comprises a frequency converter and executes an instruction of the control core to control the frequency output so as to control the operating speed of equipment connected with the execution unit; the system has the benefits that an intelligent control system integrating multistage speed/automatic speed finding, and reduces unsafe factors of manual operation.
