1. Finite Element Analysis (FEA) and Optimized Design:

   • Principle: Advanced software simulates the loads on a crane under various operating conditions, accurately calculating stress distribution. This allows designers to eliminate unnecessary material redundancy and implement targeted reinforcement in high-stress areas.

   • How to Extend Service Life:

     • Eliminating Stress Concentration: Optimizing the structural shape and smoothing stress transitions significantly reduces the initiation and propagation of fatigue cracks caused by stress concentration. Fatigue failure is the primary cause of failure in steel structures.

     • Ensuring Sufficient Rigidity and Strength: While maintaining lightweight, ensure that the structure's deflection and vibration amplitude under rated load are strictly controlled within standard limits. Excessive deformation accelerates fatigue damage and wear.

2. Using High-Strength Steel:

   • Principle: Special steel with a higher yield strength (such as S690QL) is used.

   • How to Extend Service Life: While carrying the same load, thinner plates can be used, while maintaining greater overall structural strength and fatigue resistance, fundamentally improving the durability of the "framework."
