The invention relates to a steel structure trestle hoisting device, belongs to the technical field of bridge construction machinery, and is used for solving the technical problems that traditional hoisting equipment is low in mounting precision, poor in posture adjusting efficiency and easy to deform in structure. The device comprises a portal crane main body, wherein an electric trolley of which the stroke is matched with the width of a trestle is arranged at the lower part of a fixed cross beam; the dynamic self-adaptive balance assembly adjusts load balance in real time through a rigid frame, a three-axis tilt angle sensor, a balancing weight and an electric push rod. The lifting appliance group adopts a servo motor to drive four lifting hooks to cooperatively work, and a laser positioning assembly is combined for precise positioning; the digital twinning cooperative control system integrates prediction, control logic and a pre-judgment type intervention module through an embedded industrial controller, analyzes data of an encoder and a pressure sensor in real time, predicts deformation and gravity center shift, and dynamically regulates and controls the hoisting speed, the transverse position of a trolley and the balance weight displacement. The device is suitable for high-precision rapid installation of the large-span steel structure trestle, and the construction safety and efficiency are improved.
