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 beginningin
December 1916 whenan eight-page Code
of
Safety Standardsfor
Cranes, preparedby
the ASME Committee on the Protectionof
Industrial Workers, was pres€nted to the annual meetingof
the ASME.Meetings and discussions regarding safety on
cranet
derricks, and hoists were held from 1920to
1925involving
the ASME Safety Code Correlating Committee, the Associationof
lron
and Steel Electrical Engineers, the American Museum ofSafet,
the American Engineering StandardsCommittee
(AESC)[ater
changedto
American
Standa¡dsAssociation (ASA), then
to
the USAStandards
Institute
(USASI),and
finally
to
ANSII,
Department
of
Labor
-
State ofNew Jerset Department
of
Labor and Industry-
Stateof
Pennsylvania,a¡d
the LocomotiveCrane Manufacturers Association. On June 11, 1925, the AESC approved the ASME Safety Code
Correlating
Committeet
¡ecommendation and authorized the proiectwith
the U.S. Departmentof the Navy, Bureau of Yards and Docks, and ASME as sponsors.
In
March
1926,invitations
were issuedto
50 or8anizationsto
appoint
¡epresentativesto
aSectional
Committee.
Thecall for
organization
of
this
SectionalCommittee
was sentout
October 2, 1926, and the committee organized on November 4, 1926, with 57 membe¡s repres€nting 29 national organizations. Commencing June 1,1927, and using the eight-page code publishedby ASME
in
1916 as a basis, the Sectional Committee developed the "Safety Code for Cranes, Derricks, and Hoists." The early draftsof
this safety code included requirements for jacks, butdue to inputs and comments on those drafts, the Sectional Committee decided
in
1938 to makethe requirements
for
jacksa
separate code.In
January 1943,ASA
830.2-1943 was publishedaddressint a
multitude
of equipment types andin
August 1943, ASA 830.1-1943 was publishedjust addressing jacks. Both documents were reaffirmed
in
1952 andwidely
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
onJanuary 31, 1962,
with
39 members representing 27 national ortanizations. The new committee changed the formatof
ASA 8,30.2-1943 so that themultitude of
equiPment tyPesit
addressed could be published in separate volumes that could completely cover the construction, installation,inspection, testin& maintenance, and operation of each type of equipment that was included in
the scope
of
ASA 830.2. This format change resultedin
theinitial
publicationof
830.3, 830.5, 830.6, 830.11, and 830.16 being designated as r€visionsof
830.2with
the remainder of the 830 volumes being published astotally
new volumes. ASA changed its name to USASIin
196ó and to ANSI in 1969,which
resulted in 830 volumes f¡om 1943 to 1968 being desitnated as ASA 830, USAS 830,or
ANSI 830, depending on their date of publication.In 1982, the Committee was reortanized as an Accredited Organization Committee, oPeratin8 under procedures developed by ASME and accredited by ANSI. This Standard presents a coordi-nated set
of
rulesthat
may serve as aguide to
government and other regulatory bodies andmunicipal authorities responsible for the guarding and inspection of the equipment falling
within
its
scope. The suggestions leadingto
accident prevention aregiven both
as mandatory and advisory provisions; compliancewith both types may be required by employers of their employees. ln cas€ of practical difficulties, new developments, or unnecessary hardship, the administ¡ativeor
regulatoryauthority
may grant variancesfrom
theliteral
requirementsor
Permit the useof
other
devicesor
methods,but only
when
it
is
clearlyevident that an
equivalent degreeof
protection is thereby secured. To secure uniform application and interpretation of this Standard,
administrative
or retulatoly
authorities are urged to consult the 830 Committee,in
accordancewith the format described in Section lX of the Introduction, before rendering decisions on disputed
DOrnts.

but
only
by the exerciseof
intelligence, care, andcom-mon
sense.[t
is
therefore essentialto
have personnelinvolved
in
the use and operationof
equipment whoare competent, careful, physically and mentally quali-fied, and trained
in
the proper operation of theequip-mentand the handling of loads. Serious hazards include,
but are not
limited
to, improperor
inadequate mainte'nance, overloading,
dropping
or
slipping
of
the load, obstructing the freepassageof the load,and usingequip-mentfor
a purposefor which
it
