On the article consideration different schemes mount under crane rail and follow the calculations with take into consideration conditionally placing of rail on crane bridge and the law distribution of loading from motion wheels which motion on beam of bridge crane.
In this take into consideration characters of beam that is her span, hard of section and intensive distribution of mass in main beam. Prove what way mount of rail on under crane beam have
considerable influence on her strain state.
It is made a conclusion about the influence of characteristic of beam on the resonance regime of vibration.
