The invention discloses a high-temperature automatic experiment detecting system for a pressure-speed regulating device for a crane, which is characterized by comprising a high-temperature experiment box, an automatic electrical control cabinet and an industrial control computer, wherein the high-temperature experiment box is used for placing the pressure-speed regulating device for the crane and simulating a high-temperature work environment of the crane. The automatic electrical control cabinet is used for performing logical control of loop detection on the pressure-speed regulating device for a plurality of cranes and acquiring each correlative parameter. The industrial control computer is used for monitoring the whole process and recording correlative detection data. The system simulates the high-temperature environment and greatly improves the detection efficiency and the accuracy through automatic control, monitoring and automatic recording of correlative data, thus the system is suitable for wide popularization in the field of high-temperature detection control of the pressure-speed regulating device for the cranes.
