The proposed criterion for dynamically optimizing the elastic system (ropes) of load-lifting mechanisms of cranes with translational motion, which minimizes the dynamic coefficient. The laws of motion of the elements of the lifting mechanism of the crane, in which the specified criterion can be realized, is established.

Investigation of dynamic loads in the lifting mechanism of gantry cranes «SOKIL »
In this paper, we study the dynamic loads acting on the ropes of the SOKIL portal crane lifting drive during the overload of forest logs according to the «warehouse-ship» scheme in a river port. An electrotensometric method was used to analyze the nature of changes in dynamic forces in the drive elements.

Design Optimization of Knuckle Joint Crane Lifting Mechanism by Using Particle Swarm Optimization
Mobile cranes are specialized machines designed for lifting and moving heavy loads. They feature either a wheeled or tracked chassis and are widely used in industries such as construction, heavy manufacturing, energy, and maritime operations. These cranes utilize hydraulic systems and mechanical forces to lift objects from elevated or confined spaces ...
