In the world of crane construction, especially in mining and heavy industry, welded joints are some of the most critical stress points. These joints often endure repetitive dynamic loads, vibration, and environmental fatigue.
The steel structures, lifting categories, and stress groups of cranes are designed according to guidelines set by FEM and considering the challenging working conditions. These designs are analyzed taking into account planned work cycles and the anticipated number of operating hours for the cranes. Additionally, steel structures and mechanisms are designed based on the principle of “Fatigue Stress Verification.”
