FOREWORD
This American National Standard, Safety Standard for Cableways, Cranes, Derricks, Hoists,
Hooks,Jacks,andSlings,hasbeendevelopedundertheproceduresaccreditedbytheAmerican
NationalStandardsInstitute(ANSI)(formerlytheUnitedStatesofAmericaStandardsInstitute).
ThisStandardhaditsbeginninginDecember1916whenaneight-pageCodeofSafetyStandards
for Cranes, prepared by an ASME Committee on the Protection of Industrial Workers, was
presented to the annual meeting of the ASME.
Meetingsanddiscussionsregardingsafetyoncranes,derricks,andhoistswereheldfrom1920
to 1925, involving the ASME Safety Code Correlating Committee, the Association of Iron and
SteelElectricalEngineers,theAmericanMuseumofSafety,theAmericanEngineeringStandards
Committee (later changed to American Standards Association and subsequently to the USA
Standards Institute), Department of Labor — State of New Jersey, Department of Labor and
Industry — State of Pennsylvania, and the Locomotive Crane Manufacturers Association. On
June11,1925,theAmericanEngineeringStandardsCommitteeapprovedtheASMESafetyCode
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
SectionalCommittee.ThecallfororganizationofthisSectionalCommitteewassentoutOctober
2,1926,andthecommitteeorganizedNovember4,1926,with57membersrepresenting29national
organizations. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943, was created
from the eight-pagedocument referred to inthe first paragraph. This documentwas reaffirmed
in 1952 and widely accepted as a safety standard.
Duetochangesindesign,advancementintechniques,andgeneralinterestoflaborandindustry
insafety,theSectionalCommittee,underthejointsponsorshipofASMEandtheNavalFacilities
EngineeringCommand,U.S.DepartmentoftheNavy,wasreorganizedasanAmericanNational
Standards Committee on January 31, 1962, with 39 members representing 27 national
organizations.
The format of the previous code was changed so that separate volumes (each complete as to
constructionandinstallation; inspection,testing,andmaintenance;andoperation) wouldcover
the different types of equipment included in the scope of B30.
In1982,theCommitteewasreorganizedasanAccreditedOrganizationCommittee,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
andotherregulatorybodiesandmunicipalauthoritiesresponsiblefortheguardingandinspection
of the equipment falling within its scope. The suggestions leading to accident prevention are
givenbothasmandatoryandadvisoryprovisions;compliancewithbothtypesmayberequired
by employers of their employees.
Incaseofpracticaldifficulties,newdevelopments,orunnecessaryhardship,theadministrative
or regulatory authority may grant variances from the literal requirements or permit the use of
otherdevicesormethodsbutonlywhenitisclearlyevidentthatanequivalentdegreeofprotection
istherebysecured.TosecureuniformapplicationandinterpretationofthisStandard,administra-
tive or regulatory authorities are urged to consult the B30 Committee, in accordance with the
format described in Section IX, before rendering decisions on disputed points.
This Volume of the Standard, which was approved by the B30 Committee and ASME, was
approved by ANSI and designated as an American National Standard on August 26, 2011.
