Dynamics design of mechanism of crane trolley movement [PDF]
Transport, 2006 A crane trolley with a hanging oscillating load was considered. Normal and tangential acceleration of the load and difference between the weight of the load and the strain of the rope are taken into account. Three differential dynamic equations were made.

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 ...

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
