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 problem of increasing the efficiency of the crane-manipulator by choosing the modes of movement of the swing mechanism drive during the startup process discussed in this article. Significant dynamic loads occur during the operation of manipulator cranes in the areas of transient processes. They lead to the swinging of the load on the articulated suspension. It leads to a decrease in the performance and reliability of the crane, as well as an increase in the energy consumption of the slewing mechanism drive. Optimization of the mode of movement of the mechanism of rotation of the crane-manipulator is carried out by minimizing the integral dynamic criterion, which is the root-mean-square value of the driving moment of the drive during the transition process. As a result of the optimization, a mode of starting the mechanism for turning the crane-manipulator was found, which reduces to a minimum power loading and fluctuations of the load on a hinged suspension in the radial direction. The obtained optimal start mode of the turning mechanism made it possible to increase the productivity and reliability of the crane-manipulator, as well as to reduce the energy costs of the drive.
