 FOREWORD

This American National Standard, Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings, has
been developed un der the procedures accredited by the American National Standards lnstitute (ANS!). This Standard had
its beginning in December 1916, when an eight-page "Code of Safety Standards for Cranes," prepared by the American
Society ofMechanical Engineers (ASME) Committee on the Protection oflndustrial Workers, was presented at the annual
meeting of the 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 oflron and Steel Electrical Engineers, the American Museum of
Safety, the American Engineering Standards Committee (AESC) [later changed to American Standards Association (ASA),
then to the United States of America Standards lnstitute (USAS!), and finally to ANSI), Department ofLabor- State of New
Jersey, DepartmentofLabor and lndustry- State of Pennsylvania, and the Locomotive Crane Manufacturers Association.
On June 11, 1925, the 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.
ln 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 was organized on
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 only jacks. Both documents were
reaffirmed in 1952 and widely accepted as safety standards.
Due to changes in design, advancement in techniques, and general interest oflabor 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 830.3, B30.S, B30.6, 830.11, and 830.16 being initially published as "Revisions" ofB30.2, with the remainder of the B30
volumes being published as totally new volumes. ASA changed its name to USAS! in 1966 and to ANS! in 1969, which
resulted in B30 volumes from 1943 to 1968 being designated as ASA 830, USAS B30, or ANSI B30, depending on their date
of publication. ln 1982, the Committee was reorganized as an Accredited Organization Committee operating under
procedures developed 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 both as mandatory and advisory provisions; compliance with both
types may be required by employers of their employees. ln case of practical difficulties, new developments, or unne-
cessary hardship, the administrative or regulatory authority may grant variances from the literai 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 Intro-
duction, before rendering decisions on disputed points.
Safety codes and standards are intended to enhance public safety. Revisions result from committee consideration of
factors su ch as technological advances, new data, and changing environmental and industry needs. Revisions do not imply
that previous editions were inadequate.
B30.17-2015 consolidated the requirements ofB30.17-2006 (R2012) and B30.11-2010. The Volume was completely
revised to incorporate these revisions. This edition of B30.17 incorporates revisions to a figure and to sections on
instructions, manuals, and translations, as well as other revisions.
This Volume of the Standard, which was approved by the 830 Committee and by ASME, was approved by ANS! and
designated as an American National Standard on December 21, 2020.
