Area of Science:

• Mechanical Engineering
• Materials Science
• Structural Analysis

Background:

• Crane hooks are critical lifting components requiring robust design for safety.
• Analysis of crane hook cross-sections is essential for reliable performance.
• Ensuring personnel and load safety necessitates understanding stress distribution in crane hooks.

Purpose of the Study:

• To identify the most efficient crane hook cross-sectional profile among five geometric shapes.
• To analyze the structural integrity of crane hook designs under load.
• To optimize crane hook geometry for enhanced safety and reduced failure rates.

Main Methods:

• Finite Element Analysis (FEA) using Solidworks software to model and simulate five cross-sectional profiles (circular, rectangular, trapezoidal, I-shaped, T-shaped).
• Material selection: 34CrMo4 steel for all models.
• Further analysis of the optimal profile using Python and classical curved beam equations.

Main Results:

• The trapezoidal cross-sectional crane hook demonstrated superior performance, exhibiting a Von Mises stress of 203 MPa and a factor of safety of 3.20.
• Identical boundary constraints were applied to all models for fair comparison.
• Python analysis confirmed that increased inner side parallelism in the trapezoidal shape correlates with a higher factor of safety.

Conclusions:

• The trapezoidal cross-section is the most efficient profile for crane hooks.
• Maximizing the length of the inner parallel side of the trapezoidal profile is recommended for enhanced safety.
• Optimized crane hook design significantly decreases the probability of failure and accidents.
