This invention relates to the field of mechanical engineering, specifically to a method and device for calibrating the anti-tilting entry angle of the main boom in lifting equipment. This application employs an automatic calibration process under no-load conditions. First, it collects the main boom's self-weight torque and force-related parameters based on the initial low-position angle. Then, it identifies the actual entry angle by utilizing the abrupt change in torque difference during uniform boom lifting. Finally, it calibrates the torque of auxiliary components based on this angle. Its beneficial effects are derived as follows: Manual calibration is prone to errors in the perceived entry angle and the actual force applied. This application eliminates the subjective errors of manual calibration by determining the entry angle through the abrupt change in torque difference. With accurate actual entry angle, the torque limiter can match the actual force state of the hydraulic cylinder during calculation, avoiding the error of "prematurely calculating / omitting the anti-tilting torque," thus significantly reducing the deviation between the theoretical and actual lifting weight. This solves the problem of false overload alarms affecting operational efficiency and avoids safety hazards caused by deviations in lifting weight calculation.
