For the optimization measures of the new hook of the wire rope electric crane, the following points can be referred to:

Material selection and optimization:

The material selection of the hook should meet the requirements of high strength, high toughness, and wear resistance. For example, high-strength alloy steel materials such as DG20Mn can be selected, and their mechanical properties such as yield point and tensile strength must meet the actual working conditions.

On the premise of meeting the strength requirements, it is possible to explore reducing the content of precious metal elements in materials, such as nickel (Ni) and molybdenum (Mo), in order to reduce production costs.

Structural design and optimization:

The structural design of the hook should ensure sufficient strength and stiffness, while considering weight reduction. Finite element analysis (such as using Ansys software) can be used to perform stress analysis on the hook, identify the maximum deformation position and dangerous section, and thus optimize the structure.

The cross-sectional dimensions of the hook, the maximum thickness of the horizontal section of the hook body, the maximum thickness of the vertical section, and the diameter of the handle should be carefully designed to meet the strength requirements and weight reduction goals.

Thickness optimization:

On the premise of ensuring the safety of the hook, the thickness of the hook can be optimized to reduce the weight of the hook by reducing the amount of material used. This can be achieved by conducting finite element analysis on the hook and comparing the results before and after optimization.

Security measures strengthened:

In the design of lifting hooks, safety factors should be fully considered, such as installing tilt sensors and limiters to avoid crane overturning, and introducing anti-collision systems to avoid collision accidents.

Safety handrails and guardrails should be installed around the hook to prevent personnel from entering the work area and reduce personal injury.

Manufacturing process and quality control:

The manufacturing process of the hook should strictly control the process parameters to ensure manufacturing accuracy and quality.

Strict quality testing is carried out on the hook, including material composition testing, mechanical performance testing, size testing, etc., to ensure that the quality of the hook meets the design requirements.

Post maintenance and upkeep:

Develop a detailed hook maintenance and upkeep plan, regularly inspect, lubricate, and tighten the hooks to ensure their reliability and safety.

When problems such as wear and deformation are found on the hook, it should be replaced or repaired in a timely manner to avoid safety accidents
