Introduction

Modern calculation methods require knowledge of the actual loading of structures, and external loads should be known not only by magnitude, but also by frequency of repetition. Moreover, endurance calculations require knowledge of cycle asymmetry coefficients, for which not only maximum, but also minimum stresses (loads) must be known.

Task

Group: 411

Specialty: 190602.65 Operation of transhipment equipment of ports and transport terminals

Topic: "Calculation of bridge crane box structure beam"

List of issues to be developed:

1) Common device and scope.

2) Types of crane steel structures.

3) Characteristics and main dimensions of the bridge crane.

4) Calculation of bridge crane box structure beam.

Conclusion

Modern calculation methods require knowledge of the actual loading of structures, and external loads should be known not only by magnitude, but also by frequency of repetition. Moreover, endurance calculations require knowledge of cycle asymmetry coefficients, for which not only maximum, but also minimum stresses (loads) must be known.

The natural consequence of the above is the improvement of methods for calculating metal structures of lifting and transportation machines. This includes clarifying the overload factors for the loads of those lifting vehicles that are already calculated according to the limit state, and creates the prerequisites for expanding the range of metal structures of lifting vehicles calculated according to this method.
