CMAA Specification No. 74

[weron4u]

Does anyone have a publication from CMAA titled "Specifications for Top Running and Under Running Single Girder Electric Overhead Cranes Utilizing Under Running Trolley Hoist-No. 74?"

I am looking for the section that specifies the structural design and mechanical design sections of the publication.

I am trying to determine the required safety factors of the structural components for lifing devices so that I can comply with OSHA standards. OSHA referred me to ASME and ASME referred me to CMAA.

I would like to know if this publication has what I am looking for before I buy it. Someone told me to buy the ASME standards publication and I did, however it referred me to CMAA with regards to the structural integrity of the lifting device. I would like to not spend more money on publications that I do not need

Thank you

I have copies of specifications # 70 and 74. Any crane designer should have them in his library.

Good luck
