ASME B30.23:2016 pdf free download – Personnel Lifting Systems
Within the general scope defined in Section I, ASME B30.23 may apply to hoisting and accessory equipment covered within certain volumes of the ASME B30 Standard, which is used to lift, lower, hold, or transport personnel in a platform, by wire rope or chain, from hoist equipment, or by a platform that is mounted on a boom of the hoist equipment. The lifting of personnel is not allowed using some ASME B30 Standard equipment. The ASME B30 Standard addressing the hoisting equipment to be used shall be consulted for the applicability of the ASME B30.23 volume.
This Volume establishes the designcriteria,equipment characteristics, and operational procedures that are required when hoisting equipment within the scope of the ASME B30 Standard is used to lift personnel. Hoisting equipment defined by the ASME B30 Standard is intended for material handling. It is not designed, manufactured, or intended to meet the standards for personnel handling equipment, such as ANSI/SIA A92 (Aerial Platforms). The equipment and implementation requirements listed in this Volume are not the same as that established for using equipment specifically designed and manufactured for lifting personnel. Hoisting equipment complying with the applicable volumes of the ASME B30 Standard shall not be used to liftor lower personnel unless there are no less hazardous alternatives to providing access to the area where work is to be performed. The lifting or lowering of personnel using ASME B30-compliant hoisting equipment is pro- hibited unless all applicable requirements ofthis Volume have been met.
attachment point(s): the place(s) on a boom or a personnel platform that is used to connect either the platform to the boom or to a suspension system. boom: a hinged structural member ofhoisting equipment used for supporting the hoisting tackle and load. brake: a device used for retarding or stopping motion. brake, automatic: a device that retards or stops motion, without actuation by the operator, when specific equip- ment operational parameters are met. certified welder: a person holding a current certificate, for the type of weld being applied, as proof that qualified test welds have been performed and passed in accor- dance with the American Welding Society or American Society of Mechanical Engineers criteria. design factor: the ratio of the ultimate strength of a mate- rial to its working (unit) stress, unless defined otherwise in the text of this Volume, for specific applications. ground crew: those individuals who are involved in the personnel lift, other than the hoisting equipment opera- tor and platform occupants. These individuals include riggers, signal persons, and supervision. handrail: a member supported on brackets to furnish support to platform occupants during lifting operations. hoisting equipment: a machine for lifting and lowering a load and moving it horizontally. The machine may be fixed or mobile and be driven manually, by power, or by a combination of both. As used in this Volume, the term covers all types of lifting machines addressed by the applicable volumes of the ASME B30 Standard and used to lift, lower, or transport personnel. hoisting equipment operator: a person who directly con- trols the hoisting equipment’s functions. intermediate rail: the middle member of a barrier along the edges of a platform, located approximately one-half the distance between the platform floor and top rail. latch, hook: a device used to bridge or close the throat opening of a hook for the purpose of preventing attach- ments from being dislodged.
