Google Patents US3073280A - Crane boom load height, radius, angle, and elevation indicator Your attention to this matter is greatly appreciated.US3073280A - Crane boom load height, radius, angle, and elevation indicator Thank you in advance for your thoughts on this subject. If you think you may need to see some type of detailed schematic of this setup please advise, or wish to call discuss please do so. Please review to determine if this type of perimeter barricade would meet the intent of the regulation. It would be used also on crawler cranes, as they represent a greater hazard than the rough terrain shown, and move just as much. The method I envision mounts on the crane and maintains a safe working perimeter around the crane utilizing 3" barricade warning tape, similar to that used by authorities to secure an area of a crime scene, and similar to the attached advertisement. This method uses a nondestructive method of attachment to the cranes, as the majority of our equipment is rental, and we are not allowed to alter the equipment. To aid McCarthy in complying with this rule nationwide, I was hoping we could implement a simple, but effective means to properly warn employees of this hazard. As a major Contractor in the U.S., we have performed work all over the country and have been subject to different interpretations of this regulation by different Area Offices. Louis, we discussed the different methods of complying with the above referenced regulation. Office of Construction/Maritime Compliance AssistanceĪt a 500 level training course, in St. Dale Cavanaugh of my staff at (202) 219-8136.ĭirector Office of Construction and Maritime Compliance Assistance If we can be of any further assistance, please contact me or Mr. If used as described in your letter and as shown in the accompanying illustration, the 3" barricade warning tape mounted on the crane would meet Federal OSHA's requirements for barricading the swing radius of a crane's superstructure.
This is in response to your January 24 letter requesting a statement of compliance from the Occupational Safety and Health Administration (OSHA) concerning your proposed method of maintaining a safe working perimeter outside a crane's swing radius as specified in CFR 1926.550(a)(9).
