Comparative Analysis of Hatch Cover Stocking Gantry Crane Hooks Manufactured From St37 and Weldox700 Steels Under Static Loading Conditions

Abstract

Crane hooks are used to ensure the safe transportation of loads to be lifted in load lifting and handling systems. In this study, special hooks for cranes designed to open and close the doors of warehouse zones used for ship cargo and cargo transport, and their responses under 60,000 N static loading conditions are numerically and experimentally analyzed. In the experimental study, ST37 structural steel and Weldox700 high-strength steel were used to manufacture the hook. Experimental data collected under static loading conditions of the component was measured via strain gauges sensors. It was concluded that the results of structural numerical analysis with the Finite Element Method (FEM) using ANSYS 2019 R3 analysis program with experimental data are in harmony with the results of experimental measurements. In addition, the maximum values of stress of the hook manufactured with Weldox700 and ST37 steels under the stress static loading conditions are obtained as 60[Formula: see text]MPa and 57.3[Formula: see text]MPa, respectively. In the numerical analysis results, stress value was obtained as 61.21[Formula: see text]MPa. Compared to the analysis results based on experiments and FEM, numerical analysis results showed that fudge factors in ST37 and Weldox700 steels are 1.8% and 6%, respectively. This result confirms that experimental and mathematical data were in harmony with each other and reliable.
