Theoretical Analysis and Forecasting of Gust Resistance in Rail Crane

Rail cranes are often subjected to sudden gusts of wind during the course of their work. In the event that a crane lacks adequate windproof capabilities, its movement along the track may have a significant impact on its own functionality and the safety of the surrounding equipment. Consequently, the prediction of the capacity of the rail crane to impede sudden gusts of wind, and the rational configuration of its windproof apparatus, is paramount to the crane’s ability to withstand wind. This paper conducts a systematic theoretical analysis of the gust resistance of rail crane with different windproof device configurations. It considers the movement of the wheels under wind influence and the windproof characteristics of other devices along the track direction. A theoretical formula is established to predict the gust resistance of rail crane, enabling the estimation of their maximum windproof capacity and providing a foundation for the selection and configuration of windproof devices. The calculation results demonstrate that the maximum wind capacity of the rail crane and crane parameters, wheel braking device braking torque and windproof device performance, cannot simply be considered as the maximum resistance of various types of windproof device sum. The results of the study provide a selection basis for the choice of wheel braking torque and the combination configuration of wind protection devices in the design of crane wind protection.
