The dynamic analysis of the joint trolley movement and hoisting mechanism in the tower crane
Strength of Materials and Theory of Structures, 2022 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 ...

Analysis of the effectiveness of using the block for limiting the vibrations of the load on the mechanism of movement of the bogie with various control systems [PDF]
E3S Web of Conferences, 2020 Damping load vibrations in an electric crane drive is an urgent topic for research. The swinging load has a negative effect on the mechanical part of the device, leading to its wear, and on the entire control system as a whole.

Вісник Східноукраїнського національного університету імені Володимира Даля, 2022 The article studies the dynamics of the crane movement mechanism to take measures for their reliable operation and reduce the wear of movement mechanisms. For this, the following assumptions are accepted: transverse motion is not considered, the dynamics of engines and electric drive is not considered; the crane is presented in the form of a seven–mass

Dynamic analysis of the joint movement of the hoisting and slewing mechanisms of a boom crane
Naukovij žurnal «Tehnìka ta energetika», 2023 To increase the productivity of boom cranes, the operation of individual mechanisms is combined. At the same time, dynamic loads on structural elements, drive mechanisms and loads on a flexible suspension increase, which reduces the reliability of crane operation and increases energy losses.
