It is recognized that the requirements for lifting of personnel are more stringent than those for the lifting of equipment. Our A-Frames have been designed and certified for lifting of personnel by DNV. The most critical requirement to allow this was doubling the Safe Working Load such that for the lifting of personnel, an additional 2x safety factor is achieved.
A selection of international requirements pertaining to lifting of personnel is outlined as follows:
OGP , International Association of Oil and Gas Producers, Report No. 376, April 2006, Lifting of Personnel; "The equipment used for lifting personnel for work and for personnel transfer shall be specifically designed, approved/certified and clearly marked as suitable for personnel lifting. Any equipmentnot so marked shall not be used for per-sonnel lifting.Lifting accessories and lifted equipment used for liftingpeople shall not be used for any other purpose. The factor of safety required for lifting people shall be higherthan for lifting normal loads, typically this is double for personnel lifting activities."
DNVGL-ST-0378, Standard for offshore and platform lifting appliances, Sec 11, 11.4.1 Rated Capacity. "The rated capacity shall not exceed 50% of the rated capacity for lifting of loads at the actual radius and wave height."
IMCA - Guidelines for Lifting Operations, IMCA LR 006, SEL 019, D 060, M 187, Rev 1, March 2018. A3-1. "For the raising and lowering of persons, the equiipment should have in-date certification for man riding."
