## 1 Introduction  
Among the different kinds of mobile elevating work platforms (MEWP), the scissor lift seems to be very useful and effective in practical usage. However, as in the case of other devices of this kind, the workers are exposed to various hazards. As is reported in the available literature [1], according to the Census of Fatal Occupational Injuries, a Bureau of Labor Statistics database, in 1992-1999 the number of deaths of construction workers because of different accidents was equal to 339 of which 19% were different accidents with the use of scissor lifts. According to another source [2], namely, Census of Fatal Occupational Injuries, 306 fatalities between 1992 and 2003 were caused by the usage of the different kinds of aerial lifts, and 78 of these fatalities specifically involved scissor lifts. The causes of these accidents can be quite different [3], but it seems that the most dangerous is the tip-over of the whole mobile platform [4]. The overturning can be caused by the wind load [5, 6]. According to media information, the issue of scissor lifts accidents and safety is described in [7, 8, 9, 10, 11]. It should be stressed here that according to the different standards (European Standard, Eurocode 1-4 [12], British Standard, BS 2573-1 [13], American Society of Civil Engineers, ASCE 7-16 [14], Japanese standard [15] or Chinese standard, GB/T 3811-2008 [16]), the load caused by the wind is treated as static load where the impact of the adjacent structures is omitted. In the case of the mobile elevating work platforms (MEWP), including scissor lifts, the appropriate design rules are defined in the standard EN 280-1:2022 [17]. However, such a simple approach can be inadequate in comparison with the wind load phenomenon, especially in the case of large-scale engineering structures like gantry cranes, tower cranes, or MEWP of a different kind. Therefore, the important aspect of the analysis of the wind load is the measurement of the wind load in the case of real structures [18; 19; 20]. Based on these results, the appropriate wind conditions can be imitated in the aerodynamic tunnels, where the scaled models of the real large-scale structures can be tested in order to determine the wind load (forces and moments coefficients) [21; 22; 23]. Together with the rapid development of computers and software, it is also possible to carry out numerical simulations of the airflow around crane-like structures [24; 25; 26]. Moreover, having the distribution of the static pressure (caused by wind) on the surface of the studied structure, it is possible to carry out further mechanical analysis based on the fluid-solid interaction [27]. Here, it should be noted that the papers which are devoted to the impact of the wind load on the scissor lifts are rather rare, thus the below brief survey of the literature also contains works, which consider the actions of the wind on other types of crane-like devices. However, the standard approach is to prepare the scaled model of the real large-scale structure for experimental tests in the aerodynamic tunnel. The obtained results are used to validate the numerical model [28]. It is worth noting that the wind load, especially the gust of wind, which is very often two times greater in comparison with the mean wind speed and a frequency of about 1 Hz [19], can also cause the vibration of structures. [PERSON] and [PERSON] [29] studied the displacement of a lattice tower. The results of the nonlinear dynamic analysis show that the displacement obtained from the time-history analysis is higher by about 5-28% in comparison with the static one. Next, [PERSON] et al. [30] studied the runaway of quayside container cranes subjected to transient gusty winds. They also proposed the sliding state while approaching the runaway and after a runaway caused by a wind gust. [PERSON] et al. [31] studied the interference effect of the different segments of a tower crane subjected to wind load.
