## 1 Introduction
The wind coefficients of a full-scale model of a tower crane were calculated by CFD, and then the time history of wind loads, simulated through the autoregressive method, was applied to the finite element model of a tower crane. Although the maximum wind load direction of the tower crane was perpendicular to its jib, the obtained results reveal that the maximum along-wind load direction was deflected 30\({}^{\circ}\)-60\({}^{\circ}\), and the mean ratio of the absolute value of the across-wind coefficient to the along-wind coefficient of the tower crane was about 8.56%. [PERSON] et al. [32] studied the effect of stochastic dynamic transient gusty winds on the sliding and overturning of quayside container cranes. The main conclusion is that dynamic transient gusty wind-induced peak response follows type III (Weibull) extreme value distribution. [PERSON] et al. [33] performed wind tunnel tests on an aeroelastic lattice tower model. The obtained results reveal the resonance contribution could reach a maximum of 18% of the peak response of the tower. In 2022, several interesting works were published, which concern the problem of the impact of the wind load on crane-like structures. [PERSON] et al. [34] took into consideration the problem of the outer-attached tower cranes installed on super high-rise buildings and exposed to wind-induced vibration. The numerical CFD simulations and structural FEM calculations were performed. [PERSON] et al. [35] presented a study, which concerns a similar problem. To avoid sophisticated finite element analysis of the main building, a modified generalized flexural-shear model (FSM-MS) was proposed to estimate the along-wind and across-wind displacement response of the main building and the response at the connection support of the tower crane. [PERSON] et al. [36] studied the lift effect on wind load estimation for a semi-submersible rig. Wind loads on the analyzed rig were calculated under the maritime atmospheric boundary layer. The obtained results match well with those from the wind tunnel within a \(\pm\)20% error. The influence of the lifted load on the stability of crane-like devices has also been investigated. Here, two exemplary works can be quoted, namely [PERSON] et al. [37] and [PERSON] et al. [38]. At the end of this brief survey of the literature, it is also worth mentioning the wind-induced interference effect (IE). The analysis of this problem provides insights into how the neighborhood's other structures influence the studied structure by changing the surface pressure caused by the wind. However, the cases of crane-like devices are rarely found. Here, the work by [PERSON] et al. [39] can be mentioned. The author of this work investigated the wind load and wind-induced dynamic response of three quayside container cranes. Other similar works concerning lattice structures refer to the mutual influence of a system of antennas, for example, [PERSON] et al. [40], [PERSON] et al. [41], and [PERSON] et al. [42]. The interference factor of microwave antenna dishes is found to be greater than one for some wind directions. The interferon effect has also been investigated for tall buildings [43], low-rise buildings [44; 45; 46; 47], cooling towers [48; 49], and scaffoldings [50]. This work should be treated as a continuation of the previous one [51]. The current work is devoted to the problem of determining the wind speed, which causes the tip-over of the scissor lift in the case when there are no workers on the platform and in the case when there are one, two, or more persons on the platform. The main aim of this effort is to increase the safety of the workers when the device is in service. Basically, the value of the moment induced by the wind, which causes a tip-over of the studied scissor lift, is determined based on the results obtained from the CFD simulation. However, the used numerical model is verified by the experimental tests performed in the aerodynamic tunnel, namely, the values of aerodynamic forces obtained from simulations and experiments are compared.
