Regarding the defects in the support points of explosion-proof chain hoists, the following are some solutions:

1、 Strengthen the structural design of support points

Optimize material selection:

Choose high-strength and corrosion-resistant materials as manufacturing materials for support points, such as stainless steel, high-strength alloy steel, etc.

These materials have high tensile strength and corrosion resistance, which can effectively improve the bearing capacity and service life of the support points.

Improved structural form:

Optimize the structural form of support points, such as increasing the number of support points, changing the layout of support points, etc.

By increasing the number of support points, the weight and stress of the crane can be dispersed, reducing the burden on individual support points.

Changing the layout of support points can optimize the overall force situation of the crane and improve stability.

2、 Improve the manufacturing quality of support points

Strengthen quality control:

In the manufacturing process of support points, strengthen quality control to ensure that the size, shape, and accuracy of each support point meet the design requirements.

Timely repair and handle defects and problems that occur during the manufacturing process to avoid putting defective products into use.

Improve manufacturing process level:

Adopting advanced manufacturing processes and equipment, such as CNC machine tools, laser cutting, etc., to improve the manufacturing accuracy and surface quality of support points.

These advanced manufacturing processes can ensure the dimensional and shape accuracy of the support points, improving overall quality.

3、 Strengthen support point maintenance and management

Regular inspection and maintenance:

Regularly inspect and maintain the support points of explosion-proof chain hoists, promptly identify and address potential defects and issues.

The inspection includes the wear, looseness, corrosion, etc. of the support points. If any problems are found, they should be replaced or repaired in a timely manner.

Strengthen lubrication and maintenance:

Regularly lubricate and maintain the support points to reduce friction and wear, and extend their service life.

Choose the appropriate lubricant and perform lubrication operations according to the instructions.

4、 Adopting advanced detection technology

Non destructive testing technology:

Use non-destructive testing techniques to inspect support points, such as ultrasonic testing, magnetic particle testing, etc.

These detection techniques can detect internal defects and cracks without damaging the support points, providing strong support for timely repair and treatment.

Stress monitoring technology:

Install stress monitoring equipment at the support points to monitor real-time stress changes at the support points.

By monitoring data, abnormal situations at support points can be detected in a timely manner, providing data support for taking countermeasures.
