“ANALYSIS AND OPTIMIZATION OF CRANE HOOK”

Updated: May 28, 2020

this is a analysis project using crane hook by using different material.and best use of ansys tool for optimization





INTRODUCTION


Why crane hook ?


  1. A Crane Hook is a device for lifting and moving of heavy objects. Mainly operated by hydraulic system.

  2. Whenever the lifting is taking place there is chance of failure of the crane hook due to stress

  3. So need to select appropriate material and good design for safety.

  4. In this work a crane hook is designed using forged steel with different cross sections.

  5. The von mises stress distribution are calculated for 50 ton load capacity.

  6. We tried to suggest new cross section for crane hook.



PROPERTIES


We selected

Forged Steel ( AISI 4140).

General materials used .

Forged Steel.

Structural Steel

Stainless steel









CRANE HOOK ASSUMPTIONS CONSIDERED :


  1. Hook Material Homogeneous and Isotropic

  2. Material Obeys Hooke's law

  3. The Young's modulus is same both in tension and compression

  4. The transverse sections which are plane before bending remain plane after bending also

  5. Each layer of the beam is free to expand or contract, independent of the layerabove or below it

OBJECTIVES


  • Selected various cross sections.

  • Analytical calculations and validated them using ISO standards.

  • Analysis of cross section using Ansys and try to optimize

  • Analyze variation of stresses in various cross sections.

  • Analysis of results.

  • Comparison of FOS


DATA COLLECTION

  • Interacting with the engineers from safe lifters Pvt Ltd Established in 1986

  • Taking the feedback regarding the design of crane hook and various failures

  • Taking information regarding testing techniques

  • Measuring the dimensions crane hooks of various sections

STRESS DISTRIBUTION



TRAPEZOIDAL CROSS SECTION


ANALYTICAL CALCULATIONS




STATIC STRUCTURAL ANALYSIS :

The steps involve in the Static Structural analysis are:


1.Material Selection (Mentioned

Above)

2.Modelling

3.Mesh Generation

4.Boundary Condition

5.Solution

6.Result.







STRATEGY









EQUIVALENT STRESS



RESULT


OUR SUGGESTION BULL HEAD SECTION:


CONCLUSION

  • The Crane hook has been optimized for better performance at 50 ton loading condition by providing trapezoidal section or bull head section over other sections.

  • Generating trapezoidal section or bull head section over other sections, we conclude that stresses are significantly reduced.

  • Hence, geometry of crane hook plays very important role.


FUTURE SCOPE

  • Analysis and knowledge of above results will help us while designing-other applications.

  • It will enhance our thought process towards good design.
