ASME B30.23:2005 pdf 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 Stan- dard equipment. The ASME B30 volume 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 which are required when material handling equipment, as defined by the ASME B30 Standard, is used to lift personnel. Hoisting equipment as defined by the ASME B30 Stan- dardisintended formaterialhandling. Itis notdesigned, 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 ASME B30 Standards shall not be used to lift or lower personnel unless it is not possible to accomplish the task by a less hazardous means. The lifting or lowering of personnel using ASME B30-compliant hoisting equipment is pro- hibited unless all applicable requirements ofthis volume have been met.
anti-two-blockdevice: a device that, whenactivated, disen- gages all hoisting equipment functions whose move- ment can cause two-blocking. 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. designated person: a person who is selected or assigned by the employer or employer’s representative as being competent to perform specific duties. 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 ASME B30 Standard volumes and used to lift, lower, or transport personnel.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. lifting, personnel: raising, lowering, or transporting per- sonnel using hoisting equipment covered by the ASME B30 Standard.
