The task of this paper is to research the simultaneous use of trolley and hoisting mechanism by the tower crane with a beam jib. To conduct research, a dynamic model of joint movement of mechanisms has been developed, which takes into account the main movement of drive mechanisms and oscillating movement of the load on a flexible suspension and links of mechanisms with elastic properties. A mathematical model of the motion of mechanisms is constructed on the basis of a dynamic model with the help of Lagrange equations of the second kind. For a specific jib system of the tower crane, dynamic calculations were performed using the developed mathematical model. According to the results of the calculations, a dynamic analysis of the joint movement of trolley and hoisting mechanism was carried out. The analysis revealed significant dynamic and energy overloads of mechanisms during transients (start, braking) and the presence of high-frequency oscillations in the links with elastic properties and low-frequency oscillations of the load on a flexible suspension. To reduce the overload of crane mechanisms in the areas of transients and eliminate oscillations during steady traffic, it is recommended to optimize traffic modes and develop drive control systems to implement the desired traffic modes.

“…The length of the lifting rope is not changed in the process of load transportation in order to ensure the safety of transportation. Based on the simplified model in Figure 1 and the Lagrangian dynamic equation (Nakazono, et al, 2010) and (Reutov, et al, 2016) in generalized coordinates, the following two-dimensional bridge crane mathematical model with fixed rope length is shown as follows:…”

The conventional bridge crane hoisting control method is limited by the complex factors of working conditions and generally adopts cumbersome off-line planning. In view of the problem of the inertia swing of the load caused by the trolley hauling the lifting rope during the transportation of the bridge crane, the trajectory off-line planning methods with the open-loop bring the control parameters to be complicated and tedious. A novel trajectory online planning and under-actuated control method on positioning and anti-swing for the bridge crane is proposed. According to the smooth positioning trajectory, the relationship among the motion parameters of the trolley, load swing angle, and other model parameters in the dynamic model are analyzed. With the dynamic coupling relationship between trolley motion and load swing, the function of anti-swing is designed online without changing the positioning performance. The trajectory online planning of the positioning and anti-swaying is accomplished. With the experimental and programming, the proposed method is compared with other different planning methods. The results show that this method can effectively realize the positioning and eliminating pendulum, and has the convenience of online adjusting parameters and fast response.
