Ladle crane noise

The present paper considers the vibration analysis of the ladle crane (with hoisting capacity Q=160 tons) and noise caused by working units of the crane. The vibroacoustical investigations and theoretical analysis have been applied to the main bridge with box‐trapezoid cross section. In the article there is shown comparison of the vibration acceleration and dynamic stress that have been measured in real structure with calculations obtained by means of the finite element method. The noise caused by working units of the crane have been presented for three operating conditions: when the tilting ladle was descending and was hoisting, and pass by load running of the teeming crane.
