Vibration Analysis of the Damaged Bearing Unit of the Port Crane Lifting Mechanism

Materials Science, 2023
The methods of periodically non-stationary random processes were used to analyze the vibrations of the damaged bearing unit of the lifting mechanism. To identify and analyze periodical nonstationarity of the first and second orders the least squares method was used.

Construction of theoretical models for the lifting mechanism of the foundry crane

Glavnyj mekhanik (Chief Mechanic), 2021
In the lifting drive of the foundry crane, there are emergency situations provoked by failures of bolted connections in the insert of the split drum. The latter is explained by the appearance of unequal gaps in the gearboxes of the «left» and «right» electromechanical systems driven by asynchronous motors with short-circuited rotors powered by ...

Dynamic behavior of the lifting crane mechanism

Mechanism and Machine Theory, 1995
Abstract In the present paper the motion of a lifting mechanism of crane is considered. The unloading procedure is analyzed when the mass of the mechanism is varying. Due to the mass variation a reactive force appears. The influence of the reactive force on the motion of the system is investigated.
