ASME B30.5-2018 Mobile and Locomotive Cranes
standard by ASME International, 08/06/2018
Full Description
ASME B30.5 is one of ASME's most requested safety standards-widely respected and applied throughout the building and construction industry. It addresses crawler cranes, locomotive cranes, wheel-mounted cranes, and any variations thereof that retain the same fundamental characteristics and are powered by internal combustion engines or electric motors.The scope of this Safety Standard includes only cranes of the above types that are powered by internal combustion engines or electric motors. Side boom tractors and cranes designed for railway and automobile wreck clearance, digger derricks, cranes manufactured specifically for, or when used for, energized electrical line service, knuckle boom, trolley boom cranes, and cranes having a maximum rated capacity of one ton or less are excluded.
This 2018 edition revises the Crane Operation in the Vicinity of Electric Power Lines section entirely, adds a new section on Rigger Responsibilities, and incorporates other miscellaneous revisions.B30.5 offers comprehensive solutions applying to the construction, inspection, testing, maintenance and operation of mobile and locomotive cranes. It is to be used in conjunction with equipment described in other volumes of the ASME B30 series of safety standards. Careful application of these B30 safety standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed in these volumes.
Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of mobile and locomotive cranes with B30 equipment, plus all potential governing entities.

FOREWORD
This American National Standard, Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings, has been developed under the procedures accredited by the American National Standards Institute (ANSI). This Standard had its beginning in December 1916 when an eight-page Code of Safety Standards for Cranes, prepared by the ASME Committee on the Protection of Industrial Workers, was presented at the annual meeting of ASME.
Meetings and discussions regarding safety on cranes, derricks, and hoists were held from 1920 to 1925, involving the ASME Safety Code Correlating Committee, the Association of Iron and Steel Electrical Engineers, the American Museum of Safety, the American Engineering Standards Committee (AESC) [later changed to the American Standards Association (ASA), then to the United States of America Standards Institute (USASI), and finally to ANSI], Department of Labor — State of New Jersey, Department of Labor and Industry — State of Pennsylvania, and the Locomotive Crane Manufacturers Association. On June 11, 1925, AESC approved the ASME Safety Code Correlating Committee’s recommendation and authorized the project with the U.S. Department of the Navy, Bureau of Yards and Docks, and ASME as sponsors.
In March 1926, invitations were issued to 50 organizations to appoint representatives to a Sectional Committee. The call for organization of this Sectional Committee was sent out October 2, 1926, and the committee organized November 4, 1926, with 57 members representing 29 national organizations. Commencing June 1, 1927, and using the eight-page code published by ASME in 1916 as a basis, the Sectional Committee developed the “Safety Code for Cranes, Derricks, and Hoists.” The early drafts of this safety code included requirements for jacks but, due to inputs and comments on those drafts, the Sectional Committee decided in 1938 to make the requirements for jacks a separate code. In January 1943, ASA B30.2-1943 was published addressing a multitude of equipment types and in August 1943, ASA B30.1-1943 was published addressing just jacks. Both documents were reaffirmed in 1952 and widely accepted as safety standards. Due to changes in design, advancement in techniques, and general interest of labor and industry in safety, the Sectional Committee, under the joint sponsorship of ASME and the Bureau of Yards and Docks (now the Naval Facilities Engineering Command), was reorganized on January 31, 1962, with 39 members representing 27 national organizations. The new committee changed the format of ASA B30.2-1943 so that the multitude of equipment types it addressed could be published in separate volumes that could completely cover the construction, installation, inspection, testing, mainte- nance, and operation of each type of equipment that was included in the scope of ASA B30.2. This format change resulted in the initial publication of B30.3, B30.5, B30.6, B30.11, and B30.16 being designated as “Revisions” of B30.2 with the remainder of the B30 volumes being published as totally new volumes. ASA changed its name to USASI in 1966 and to ANSI in 1969, which resulted in B30 volumes from 1943 to 1968 being designated as “ASA B30,” “USAS B30” or “ANSI B30”
depending on their date of publication.
In 1982, the committee was reorganized as an Accredited Organization Committee, operating under procedures devel- oped by ASME and accredited by ANSI. This Standard presents a coordinated set of rules that may serve as a guide to government and other regulatory bodies and municipal authorities responsible for the guarding and inspection of the equipment falling within its scope. The suggestions leading to accident prevention are given as both mandatory and advisory provisions; compliance with both types may be required by employers of their employees.
In case of practical difficulties, new developments, or unnecessary hardship, the administrative or regulatory authority may grant variances from the literal requirements or permit the use of other devices or methods, but only when it is clearly evident that an equivalent degree of protection is thereby secured. To secure uniform application and interpretation of this Standard, administrative or regulatory authorities are urged to consult the B30 Committee in accordance with the format described in Section IX of the B30 Standard Introduction, before rendering decisions on disputed points.
Safety codes and standards are intended to enhance public safety. Revisions result from committee consideration of factors such as technological advances, new data, and changing environmental and industry needs. Revisions do not imply that previous editions were inadequate.
The ASME B30.5-2007 edition added responsibilities to be assigned in the worksite organization. The 2011 edition included minor revisions and the addition of Nonmandatory Appendix A on critical lifts. The 2014 edition incorporated many global B30 changes including the addition of personnel competence and translation requirements as well as other revisions made throughout the document. This 2018 edition revises the Crane Operation in the Vicinity of Electric Power Lines section entirely, adds a new section on Rigger Responsibilities, and incorporates other miscellaneous revisions.
This edition of the B30.5 Volume was approved by the B30 Committee and by ASME, and was approved by ANSI and designated as an American National Standard on June 12, 2018.
