To address the issue of frequent replacement of current collectors in double beam cranes, the following is a solution strategy:

1. Cause analysis

Environmental factors: A humid and highly corrosive working environment may cause rapid aging or damage to the collector.

Operational factors: Irregular operating habits, such as frequent high-intensity lifting or sudden braking, may increase the wear of the collector.

Equipment quality: Quality issues with the collector itself, such as materials that are not durable or poorly designed, may also lead to frequent replacement.

2. Solution strategy

2.1 Improving the working environment

Keep dry: By adding dehumidification equipment or improving ventilation conditions, reduce the humidity of the working environment.

Anti corrosion treatment: Apply anti-corrosion treatment to the crane and its collector, such as spraying anti-corrosion paint or using anti-corrosion materials.

2.2 Standardized operating habits

Training operators: Strengthen the training of operators to ensure that they understand and follow the correct operating procedures.

Avoid high-intensity lifting: Try to avoid frequent high-intensity lifting to reduce wear and tear on the collector.

Smooth braking: Try to be as smooth as possible during braking to avoid sudden braking that may impact the current collector.

2.3 Improving equipment quality

Choose high-quality current collectors: When purchasing current collectors, choose well-known brands and products with guaranteed quality.

Customized design: Based on the actual working environment and usage requirements of the crane, customize the design of the collector to ensure that its structure and materials meet the actual requirements.

2.4 Regular Inspection and Maintenance

Daily inspection: Regularly inspect the current collector and promptly address any issues found.

Replace worn parts: Replace severely worn collector components in a timely manner to prevent the problem from escalating.

Lubrication and maintenance: Regularly lubricate and maintain the current collector to ensure its normal operation.

2.5 Use of spare parts

Prepare sufficient spare parts: In response to sudden damage to the collector, prepare sufficient spare parts to ensure timely replacement.

3. Implementation and monitoring

Develop Implementation Plan: Based on the above strategies, develop a detailed implementation plan, clarify the responsible person, timeline, etc.

Regular evaluation: Conduct regular evaluations of the implementation plan and adjust strategies based on the evaluation results.

Monitoring execution status: Monitor the execution status of the implementation plan to ensure that all measures are effectively implemented.
