F O R E W O R D

This American National Standard, Safety Standard for Cableways, Cranes, Derricks, Hoists,

Hooks, [acks, and Slings, has been developed under the procedures accredited by the American

National Standard s Institute (formerly the United States of America Standards Institute). This

Standard had its beginning in December 1916 when an eight-page Code of Safety Standards for

Cranes, prepared by an ASMECornrnittee on the Protection of Industrial Workers, was presented

to 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 of Iron and

Steel Electrical Engineers, the American Museum of Safety, the American Engineering Standards

Cornrnittee (later changed to American Standards Association and subsequentIy to the USA

Standards Institute), Departrnent of Labor - State of New Jersey, Departrnent of Labor and

Industry - State of Pennsylvania, and the Locomotive Crane Manufacturers Association. On

June 11, 1925, the American Engineering Standards Cornrnittee approved the ASME Safety Code

Correlating Cornrnittee's recornrnendation and authorized the project with the U.S. Departrnent

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 Cornrnittee. The call for organization of this Sectional Cornrnittee was sent out October

2,1926, and the cornrnittee organized November 4,1926, with 57members representing 29national

organizations. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943,was created

from the eight-page docurnent referred to in the first paragraph. This document was reaffirmed

in 1952 and widely accepted as a safety standard.

Due to changes in design, advancement in techniques, and general interest of labor and industry

in safety, the Sectional Cornrnittee, under the joint sponsorship of ASME and the Naval Facilities

Engineering Command, U.S. Departrnent of the Navy, was reorganized as an American National

Standards Cornrnittee on January 31, 1962, with 39 members representing 27 national organiza-

tions.

The format of the previous code was changed so that separa te standard s (each complete as to

construction and installation; inspection, testing, and maintenance; and operation) will cover the

different types of equipment included in the scope of B30.

In 1982, the Cornrnittee was reorganized as an Accredited Organization Cornrnittee, operating

under procedures developed by the ASME and accredited by the American National Standards

Institute.

This Standard presents a coordinated set of rules that may serve as a guide to governrnent

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.

In case of practical difficulties, new developments, or unnecessary hardship, the adrninistrative

or regulatory authority may grant variances from the literal requirements or perrnit 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,

adrninistrative or regulatory authorities are urged to consult the B30 Cornrnittee, in accordance

with the forrnat described in Section ID , before rendering decisions on disputed points.

This volurne of the Standard, which was approved by the B30 Cornrnittee and by ASME, was

approved by ANSI and designated as an American National Standard on September 28, 2005.

Safety codes and standard s are intended to enhance public safety. Revisions result from cornrnit-

tee consideration offactors such as technological advances, new data, and changing environrnental

and industry needs. Revisions do not imply that previous editions were inadequate.

S E C TIO N X : A D D IT IO N A L G U ID A N C E

The equipment covered by the B30Standard is subject

to hazards that cannot be abated by mechanical means,

but only by the exercise of intelligence, care, and com-

mon sense. It is therefore essential to have personnel

involved in the use and operation of equipment who

are competent, careful, physically and mentally quali-

fied, and trained in the proper operation of the equip-

ment and the handling of loads. Serious hazards include,

but are not limited to, improper or inadequate mainte-

nance, overloading, dropping or slipping of the load,

obstructing the freepassage ofthe load, and using equip-

ment for a purpose for which it was not intended or

designed.

ix


The B30 Standards Committee fully realizes the

importance of proper design factors, minimum or

maximum dimensions, and other limiting criteria of

wire rope or chain and their fastenings, sheaves, sprock-

ets, drums, and similar equipment covered by the stan-

dard, all of which are closely connected with safety.

Sizes, strengths, and similar criteria are dependent on

many different factors, often varying with the installa-

tion and uses. These factors depend on the condition of

the equipment or material; on the loads; on the accelera-

tion or speed of the ropes, chains, sheaves, sprockets,

or drums; on the type of attachments; on the number,

size, and arrangement of sheaves or other parts; on envi-

ronmental conditions causing corrosion or wear; and on

many variables that rnust be considered in each individ-

ual case. The requirements and recommendations pro-

vided in the volurnes rnust be interpreted accordingly,

and judgment used in determining their application.

SECTION 22-0.1: SCOPE OF 830.22

The scope includes only cranes of the types described

in para. 22-0.2.1, articulated by hydraulic cylinders,

which are powered by internal combustion engines or

electric motors and are mounted on a mobile chassis or

stationary installation. Frequently, articulating cranes

are equipped with a load hoist mechanism to broaden

their versatility. Load hoist mechanisms equipped

machines are covered by this Volume.

Some basic machine types within this scope are con-

vertible for excavating work and other uses not consid-

ered to be lifting service. The requirements of this

Volume are applicable only to such machines when used

as lifting cranes.

Exemptions from this Volume include

a

all units with a maximum rated capacity of 1 ton

or less

b

all units with booms constructed of nonconduc-

tive-type materials

e

all units equipped with or designed primarily for

personnel baskets, platforms, ladders, etc.

SECTION 22-1.1: LOAD RATINGS

Liftin g Perf ormance

a The margin of stability for determination of load

ratings, with booms of stipulated lengths at stipulated

working radii for the various types of crane mountings,

is established by taking a percentage of the loads that

will produce a condition of tipping or balance with the

boom in the least stable direction, relative to the mount-

ing. The load ratings shall not exceed the following

percentages for cranes, when tested in accordance with

ANSIjSAE J765 for indicated types of mounting.

NOTE:

(1) As a precaution, while testing for free ratings, stabilizers

should be loosely applied; rail clamps should not be used.

b The effectiveness of these preceding stability fac-

tors will be influenced by such additional factors as

freely suspended loads; ral, wind, or ground conditions;

condition and inflation to tire manufacturer's highway-

rated pressure of rubber tires; boom lengths; proper

operating speeds for existing conditions; and, in general,

careful and competent operation.

22-1.1.2 Load Ratin gs Wh ere Struc tural Competence

Governs Lift ing Performance

a Load ratings for some radii are limited by the

stability of the crane. However, in some of the operating

ranges, the ratings may be lirnited by factors other than

stability, such as the following conditions:

(1) Load ratings at some radii may be based on

structural competence of the crane rather than stability.

(2) A nonsymmetrical mounting requires a higher

loading to produce a condition of tipping in a direction

other than that ofleast stability on which the load ratings

are established. Therefore, if the crane specification

includes additional ratings for directions other than the

least stable, such ratings also may be govemed by struc-

tural competence rather than stability. For such specified

additional ratings, the work area shall be indicated, and

for those ratings which might be govemed by tipping

loads, the applicable percentage factors in para.

22-1.1.1(a) shall not be exceeded.

b For all operational applications, the crane load

ratings established by the manufacturer shall not be

exceeded.

22-1.1.3 L oad Rati ng Ch art

a A durable rating chart or charts with legible letters

and figures shall be provided with each crane and

attached in a location available to the operator while at

the controls. The data and information to be provided

on these charts shall include, but not be limited to, the

following:

(1) a range of manufacturer's crane load ratings at

stated operating radii, work areas, boom lengths, confg-

urations, and jib lengths

(2) in areas where no load or reduced load is to be

handled, a work area figure or load rating chart shall

so state

(3) recommended reeving for the hoist lines shall

be shown if the crane is equipped with a winch

b In addition to the data required on the load rating

chart, the following information shall be shown either

on the load rating chart or in the operating manual:

(1) recommended tire pressure chart, where appli-

cable

(2) cautionary or warning notes relative to limita-

(3) the maxirnum telescopic travellength of each

boom telescopic section

(4) whether sections are telescoped with power or

manually

(5) sequence and procedure for extending and

retracting telescopic boom section

extending operation, and any limiting conditions or cau-
