Substantiation of improvements for the bearing structure of an open car when unloading with grab bucket

Abstract

A higher efficiency of international transportation can be maintained by mutual cooperation of transport operators. Nowadays the most popular are rail and maritime transportation. The research into the working conditions of transport means during international rail/sea transportation had demonstrated that the most vulnerable element is the bearing structure of a rail car. The damage is caused by the loads which exceed the allowable values. Besides, it should be noted that the bearing structure of a car is not suited to all operation modes, e.g. the unloading with a grab, transportation by a train ferry, etc.
