Why You Need CMAA Specification 70




CMAA Specification 70 is not just a technical document, but also a tool for ensuring the safety, efficiency and reliability of your multiple girder cranes. By following the standards and guidelines provided by CMAA Specification 70, you can benefit from:


  • Improved crane performance and durability. CMAA Specification 70 covers the structural, mechanical and electrical design of multiple girder cranes, as well as the crane service classifications that determine the appropriate design factors and load combinations. By adhering to these specifications, you can ensure that your cranes are designed and built to withstand the expected loads and stresses, and to operate smoothly and accurately.



  • Reduced crane maintenance and repair costs. CMAA Specification 70 also provides information on the crane inquiry data sheet, which is a document that specifies the crane requirements and specifications for a particular application. By filling out this data sheet and submitting it to your crane manufacturer or supplier, you can ensure that you get the right crane for your needs, and avoid unnecessary modifications or replacements later on.



  • Enhanced crane safety and compliance. CMAA Specification 70 is based on the latest industry best practices and research, and is updated regularly to reflect the changes in technology and regulations. By following CMAA Specification 70, you can ensure that your cranes meet the applicable codes and standards, such as OSHA, ANSI, ASME and NFPA. You can also reduce the risk of crane accidents, injuries and damages, and protect your workers, equipment and environment.



How to Use CMAA Specification 70




CMAA Specification 70 is not a substitute for the manufacturer's instructions or recommendations, but rather a supplement that provides additional information and guidance. Therefore, you should always consult with your crane manufacturer or supplier before purchasing, installing or operating a multiple girder crane.

To use CMAA Specification 70 effectively, you should:


  • Read and understand the general specifications section, which provides an overview of the scope, purpose, definitions and references of CMAA Specification 70.



  • Determine the crane service classification for your application, which defines the load spectrum, load cycles and operating conditions of your crane.



  • Check the structural design section, which provides formulas and tables for calculating the stresses, deflections and fatigue factors of the crane components.



  • Check the mechanical design section, which provides specifications and recommendations for the hoisting mechanism, trolley mechanism, bridge mechanism and other mechanical parts of the crane.



  • Check the electrical equipment section, which provides specifications and recommendations for the motors, controllers, brakes, limit switches and other electrical parts of the crane.



  • Fill out the crane inquiry data sheet, which provides a template for specifying your crane requirements and specifications.



  • Compare your data sheet with the individual manufacturers' data sheets and select the best option for your application.



We hope this article has helped you understand how to use CMAA Specification 70 for your multiple girder cranes. If you have any questions or comments, please feel free to contact us or leave a comment below. c481cea774
