The invention discloses a wind load control system, method and apparatus and hoisting equipment. According to the current boom elevation angle and the boom combined information of the hoisting equipment, the current boom gesture of the hoisting equipment is determined; the current wind load of the hoisting equipment is calculated based on a current boom head wind speed, a current lifting hook position and a current lifting weight; the current wind load is compared with the maximum wind load born under the current boom gesture so as to determine whether the hoisting equipment can work safely; therefore, quantitative analysis on the wind load of the hoisting equipment can be achieved according to different boom gestures, the accuracy and the safety of hoisting control under the effect of wind load are improved, and the purposes of widening the working range of the hoisting equipment and improving the attendance rate, namely utilization rate, of the hoisting equipment are achieved. Moreover, due to comprehensive consideration of the influence of such factors as current lifting weight on the wind load, the wind load control system disclosed by the invention can be used for further improving the accuracy of hoisting control compared with the prior art which just takes the influence of wind speed on the wind load into consideration.
