Investigation of dynamic loads in the lifting mechanism of gantry cranes «SOKIL »

Herald of the Odessa National Maritime University
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.

Dynamic analysis of the joint movement of derricking mechanism and lifting mechanism of a load during a steady-state turn of a jib crane

Strength of Materials and Theory of Structures
Increasing the productivity of jib cranes is an urgent problem of improving their operation. Combining the work of separate mechanisms is one of the ways to increase the productivity of jib cranes. The aim of the study is to build a mathematical model and conduct a dynamic analysis of the crane jib system with simultaneous operation of the derricking ...
