B30.5 Foreword

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 (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 ASME Committee 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 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 June 11, 1925, the American Engineering Standards Committee 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. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943, was created from the eight-page document 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 Committee, under the joint sponsorship of ASME and the Naval Facilities Engineering Command, U.S. Department of the Navy, was reorganized as an American National 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 construction and installation; inspection, testing, and maintenance; and operation) would cover the different types of equipment included in the scope of B30. In 1982, the Committee was reorganized as an Accredited Organization Committee, operating under procedures developed by ASME and accredited by the American National Standards Institute. 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 or 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 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. This edition of the ASME B30.5 standard includes minor revisions and the addition of the Nonmandatory Appendix A on Critical Lifts Suggestions for the improvement of this volume of the Standard are welcome and should follow the outline presented in Section VIII of the standard introduction. They should be addressed to The American Society of Mechanical Engineers; Secretary, B30 Main Committee; Three Park Avenue; New York, NY 10016-5990. This volume of the Standard, which was approved by the B30 Committee and by ASME, was approved by ANSI and designated as an American National Standard on November 20, 2007.

07-458 B30.5 Critical Lifts March 24, 2008

Proposal: Define "critical lift" and add a Non-mandatory appendix to B30.5 The following paragraph to be inserted within the B30.5 SECTION 5-3-2: OPERATING PRACTICES. 5-3.2.3 Critical Lifts

Certain hoisting or lifting operations are recognized to have increased levels of risk to personnel or property. The criteria to categorize a lift as "critical" on this basis are established by site supervision, project management, a qualified person or company policies. Lift planning and oversight shall be tailored to each hoisting operation and shall be sufficient to manage varying conditions and their associated hazards. The information presented in Non-Mandatory Appendix A suggests one method of documenting the planning and oversight necessary to reduce that risk. The following definition of "Critical Lifts" to be inserted in B30.5 SECTION 5-0.2: DEFINITIONS, Within 5-0.2.2 General. Definition: Critical lift: A hoisting or lifting operation which has been determined to present an increased level of risk beyond normal lifting activities. For example, increased risk may relate to personnel injury, damage to property, interruption of plant production, delays in schedule, release of hazards to the environment, or other jobsite factors.

NON-MANDATORY APPENDIX "A" CRITICAL LIFTS

This appendix is not a part of Volume B30.5 and is included for information purposes only. A1 Critical Lift Identification. Classification of a lift as being "Critical" is often determined by company policy but may also be determined independently by site supervision, project management or a qualified person. It is not the purpose of the B30.5 volume to designate, authorize, or sanction any lift as being critical. Critical lifts can occur anytime during lifting, preparation for a lift, or dismantling from a lifting operation. Examples of commonly accepted critical lift criteria: A1.1 The total load being lifted is in excess of a predetermined threshold. This threshold may vary with company policy and with consideration given to such criteria as crane capacity, available rigging, and employee experience. A1.2 The lifted load exceeds a predetermined percentage of the crane's capacity, as shown on the crane manufacturer's applicable load/capacity charts for the configuration being used. Responsible management may adjust this percentage depending on the jobsite conditions. A1.3 The lifting of personnel in a personnel basket or platform. Such hoisting of personnel shall follow the requirements and procedures of the B30.23 Volume and special provisions as mandated by OSHA. A1.4 The lifting operation involves more than one crane lifting a common load with shared loading of both cranes. Multi-crane lifts utilizing one crane, as a tailing crane may not be considered a critical lift unless another of these listed criteria applies. A1.5 The item being lifted is unique and if damaged, would be irreplaceable or not repairable and is vital to a system, facility, or project operation. A1.6 The item is being removed from a structure; such as in demolition work, where the actual weight and the structural integrity are in doubt. A1.7 The lifting operation is within a boom length of power lines (see 5-3.4.5 Operation Near Electric Power Lines), over active work areas, occupied buildings, public roadways, transportation systems, etc. A1.8 Other crane activities such as but not limited to the following which may be considered as critical lifts as determined by either site management or project supervision: a) Lifting with limited clearance or in confined work areas. b) Lifting at heights which make control of the load difficult c) Lifts utilizing specially engineered load rigging system.

A2 Critical Lift Plans. A critical lift plan, with documentation as determined by site supervision or project management, shall be prepared on all critical lifts prior to the commencement of those lifts. The lift plan shall include items necessary to address the special conditions of each lift. These items should included but not be limited to: A2.1 The total weight to be lifted, which includes but is not limited to the weights of: Load Block and ball Below the hook lifting devices, lifting bars, or beams Jib, erected or stowed as applicable Rigging, including slings and hardware Rope, load line as applicable A2.2 The crane placement location with consideration given to: Foundation, ground support Boom swing area as applicable Track or outrigger loading Electrical hazards Obstructions and clearances Load path A2.3 Identification of the crane(s) to be used describing the required configurations(s) noting: Capacity Lifting arrangement Load radius requirements Percentage of crane capacity needed A2.4 Sling and rigging selection, which should include but not be limited to: Type of arrangement Identified sling angles Number and size of slings Sling rated capacities and lengths Hardware selection and sizing A2.5 Diagrams(s) of lifting area dimensions including: Site layout information and rigging arrangements Pick up and placement locations Obstructions and clearances Jobsite access and egress for the load Load orientation A2.6 Diagram of rigging configuration including: Load center of gravity Arrangement of slings and below the hook lifting devices Hardware arrangements Capacities of slings and hardware Pick points on the load Calculated sling angles Types of sling hitches

A3 Critical Lift Approvals. All critical lift plans shall be reviewed for approval by responsible jobsite personnel including site management, rigging supervision, the crane operator performing the lift, qualified personnel designing the lift, and safety personnel as applicable. These approvals shall be signed and dated. Any disapproval(s) by the responsible personnel shall cause the total plan to be re-examined and, if necessary revised to gain final approval (or "to resolve any disapproval"). All revisions shall also be signed and dated. A4 Critical Lift Pre-lift Meeting. Before performing a critical lift and following any revision(s) to the original plan, participating personnel shall meet to accomplish the following: Review and discuss the details of the critical lift plan. Discuss any hazards, delays, project coordination, unique conditions, emergency contingencies, safety concerns, etc. Resolve any questions or concerns before commencing lifting operations. Assign personnel and responsibilities Establish communication methods

Rope Inspection and Replacement March 25, 2008

Proposal: Add new para.5-2.4.2, Inspection, as follows: 5-2.4.2 (a)(1)(e) internal wear or broken wires for ropes operating on synthetic sheaves. Common indicators of internal deterioration include localized reduction in rope diameter, corrosion between the strands, localized lengthening of rope lay wire displacement or wire distortion. [Re-letter existing (e) as (f).]

Proposal: Replace existing paragraph 5-2.4.3(c) as follows: 5-2.4.3 (c) Broken wire removal criteria cited in this volume applies to wire rope operating on multilayer drums regardless of sheave material. Rationale: The proposal addresses non-metallic sheaves. It replaces item 06-1455, which was withdrawn.

TR #: 08-1550 and 08-1554 combined Standard: B 30.5 Subject: 5-3.4.5, Operating Near Electric Power Lines Updated: February 22, 2010

Proposal: This main committee ballot is to change section 5-3.4.5, Operating Near Electric Power Lines, to establish a separate condition for de-energized lines not in transmission and distribution service. This separate condition would include the allowance currently in 5-3.4.5.2(c) for the owner of the lines (or a designated representative of the electrical utility) to determine the necessity of grounding the lines. 5-3.4.5 Operating Near Electric Power Lines 5-3.4.5.1 General. This volume recognizes that operating mobile cranes where they can become electrified from electric power lines is an extremely hazardous practice. It is advisable to perform the work so there is no possibility of the crane, load line, or load becoming a conductive path. [See Fig. 18, sketches (a) and (b).] Cranes shall not be used to handle materials stored under electric power lines unless any combination of boom, load, load line, or machine component cannot enter the prohibited zone. Operating mobile cranes where they can become electrified by with electric power lines is not recommended unless there is no less hazardous way to perform the job. Any overhead wire shall be considered to be an energized line unless and until the person owning such line or the electrical utility authorities indicate that it is not an energized line. Crane operators and other personnel directly involved with the lifting operations shall not rely on the coverings of wires for their protection. If cage-type boom guards, insulating links, or proximity warning devices are used on cranes, such devices shall not be a substitute for the requirements of para. 5-3.4.5, even if such devices are required by law or regulation. In view of the complex, invisible, and lethal nature of the electrical hazard involved and to lessen the potential of false security, instructions on the electrical hazard involved, operating conditions for the devices, limitations of such devices, and testing requirements prescribed by the device manufacturer, if used, shall be understood by the crane operator, crew, and load-handling personnel. The required clearances to electrical lines, established in Table 2 of para. 5-3.4.5, shall be maintained, regardless of any devices used on the crane. Five Four conditions to consider when operating a mobile crane near electric power lines are the following: (a) power transmission and distribution lines de-energized and grounded as in para. 5-3.4.5.2 (b) other lines de-energized as in para. 5-3.4.5.3 (c) power lines energized, crane operating less than the erected/fully extended boom length away as in para. 5-3.4.5.3.4 [see Fig. 18, sketch (c)]

1

(d) power lines energized, crane within prohibited zone as in para. 5-3.4.5.4.5 (e) crane in transit, no load, and boom lowered as in para. 5-3.4.5.5.6 5-3.4.5.2 Crane Operation Near De-energized and Grounded Electric Power Transmission and Distribution Lines. This is the preferred condition under which the operation can be performed. The for crane operation near power transmission and distribution lines since the hazard of injury or death due to electrocution has been removed. The following steps shall be taken to ensure de-energization of the power lines: (a) The power company or owner of the power transmission and distribution lines shall deenergize the lines. (b) The lines shall be visibly grounded to avoid electrical feedback and appropriately marked at job site location. (c) The necessity for grounding of wiring that has a manufacturer's applied coating of insulation and is a 600-V service or less shall be determined by electrical utilities or the owner of the power line. (d)(c) A qualified representative of the owner of the lines or a designated representative of the electrical utility shall be on the site to verify that the steps of paras. 5-3.4.5.2(a) and (b) have been completed and that the lines are not energized. (e)(d) Durable signs shall be installed at the operator's station and on the outside of the crane warning that electrocution or serious bodily injury may occur unless minimum clearances, as specified in Table 2 [see Table 2 and Fig. 18, sketch (d)], are maintained between the crane or the load being handled and energized power lines. (f) If cage-type boom guards, insulating links, or proximity warning devices are used on cranes, such devices shall not be a substitute for the requirements of para. 5-3.4.5, even if such devices are required by law or regulation. In view of the complex, invisible, and lethal nature of the electrical hazard involved and to lessen the potential of false security, instructions on the electrical hazard involved, operating conditions for the devices, limitations of such devices, and testing requirements prescribed by the device manufacturer, if used, shall be understood by the crane operator, crew, and load-handling personnel. The required clearances to electrical lines, established in Table 2 of para. 5-3.4.5, shall be maintained, regardless of any devices used on the crane. 5-3.4.5.3 Crane Operation Near Other De-energized Lines. For lines that are not in transmission or distribution service, and are insulated for the voltage at which they operate, the following steps shall be taken to ensure de-energization of the lines: (a) The power company or owner of the lines shall de-energize the lines. (b) The necessity for grounding the lines shall be determined by the owner of the lines or a designated representative of the electrical utility (c) A qualified representative of the owner of the lines or a designated representative of the electrical utility shall be on the site to verify that the steps of paras. 5-3.4.5.3(a) and (b) have been completed and that the lines are not energized. 5-3.4.5.4 Crane Operation Within the Erected/Fully Extended Boom Length of the Prohibited Zone, With the Power Lines Energized 5-3.4.5.3.4 (j) deleted (the rest of the text stays the same) 5-3.4.5.5 Crane Operation Within the Prohibited Zone With the Power Lines Energized

2

5-3.4.5.54(g) deleted (the rest of the text stays the same) 5-3.4.5.6 Operations in Transit With No Load and Boom Lowered (text stays the same) Explanation/Rationale: Previously approved ballot TR 06-1458 allowed for the owner of the lines (or a designated representative of the electrical utility) to determine the necessity of grounding the lines. Now that the approved wording from TR 06-1458 has been published in B30.5-2007, Section 53.4.5 is inconsistent, as 5-3.4.5.2 is for power lines de-energized AND grounded, while down in 53.4.5.2 (c) an exception to the grounding requirement is present. This revision resolves this inconsistency by adding this fifth condition and deleting 5-3.4.5.2 (c). Note: In 5-3.4.5.1 (d) the ".4" at the end of 5-3.4.5.4 is struck-through, but may not appear to be so when viewing the ballot.

5-3.4.5, Operating Near Electric Power Lines

Proposal: This ballot is to revise (editorially) Figures 18 (a), (b), (c), and (d) to change the references from Table 1 to Table 2. In the following diagrams, everything marked Table 1 will become Table 2.

Explanation/Rationale: In the 2004 edition a new Table 1 for Crane Load Ratings was created from an in-text table, making the table for required clearance now Table 2. Figures 18 (a), (b), (c), and (d) were not revised at the time to be in alignment with this renumbering.

TR #: 08-1552 Standard: B 30.5 Subject: 5-1.1.3 Load Rating Chart Created: 8/ 25/08

Proposal: Replace existing proposal with the following: 5-1.1.3 Load Rating Chart 5-1.1.3(a)(3) Where ratings are limited by structural, hydraulic, or factors other than stability, the limitations shall should be shown and emphasized on the rating charts. If rating limitations are not shown on the chart; the crane manufacturer or final assembler shall provide information about those limitations to crane owners upon request Rationale: Committee believes safety is better served by a less complex load chart however, crane owners may need to know what areas of a rating chart are based on what limiting factors in order to comply with government mandated testing requirements.

TR #: 08-1565 Standard: B30.5 Subject: 5-1.9.11 (g), Miscellaneous Equipment Updated: February 22, 2010

Proposal: This main committee ballot is to modify the paragraph requiring durable warning signs relating to operation near electric power lines currently in 5.1 (Construction and Characteristics), and delete the similar paragraphs from Section 5.3 (Operations). 5-1.9.11 (g) A Durable signs shall be installed, visible from at the operator's station, and on the outside of the crane warning that electrocution or serious bodily injury may occur, unless a minimum clearance of 10 ft (3 m) is maintained between energized lines (up to 50 kV) and the crane, load line, rigging and or load for energized power lines up to 50 kV, and that greater clearances are required for higher voltages [refer to Table 2 para. 5-3.4.5(a)(1)]. 5-3.4.5.2 (e) Durable signs shall be installed at the operator's station and on the outside of the crane warning that electrocution or serious bodily injury may occur unless minimum clearances, as specified in Table 2 [see Table 2 and Fig. 18, illustration (d)], are maintained between the crane or the load being handled and energized power lines. 5-3.4.5.3(i) Durable signs shall be installed at the operator's station and on the outside of the crane warning that electrocution or serious bodily injury may occur unless minimum clearances, as specified in Table 2 [see Table 2 and Fig. 18, illustration (d)], are maintained between the crane or the load being handled and energized power lines. Explanation/Rationale: Providing durable warning signs regarding electrical hazards should be in the construction section and therefore standard on all cranes. The requirements of the two paragraphs in the operations section are combined into one statement in the construction section and the two paragraphs in the operations section will be deleted. Note: Maintaining the signs is a requirement for the crane owner per para. 5-3.1.3.1.1 (e). The reference change is needed since 5-3.4.5 was substantially changed with the B30.5a-1995 addenda to B30.5 1994 version and paragraph 5-3.4.5(a)(1) was deleted.

5-1.7.5(a) ­ Sheave Sizes - Existing Boom hoisting sheave shall have pitch diameters of not less than 15 times the minimal diameter of rope used. Proposed ­ 5-1.7.5(a): Boom hoisting sheaves shall have pitch diameters of not less than 15 times the nominal diameter of the rope used, except as noted in 5-1.7.2(c) and 51.7.2(d). Rationale: 5-1.7.2(c) and (d) apply to specific applications related to use of rotation resistant ropes as boom hoist reeving when luffing attachments or boom and mast attachments are used.

10-409 B30.5 ­ Mobile Cranes Revise 5-2.4.3 (b)(7) July 20, 2010

Revise 5-2.4.3(b) (7) as follows: 5-2.4.3 Rope Replacement (7) In standing ropes, three or more broken wires in one rope lay anywhere in the wire rope or two or more broken wires at end connections. in standing ropes, more than two broken wires in one lay in section beyond end commotions or more than one broken wire at an end connection.

Rationale: To be in line with the WRTB Wire Rope Users Manual-Fourth Edition (2006) way of addressing this subject. The verbiage in the two documents is as follows. existing 5-2.4.3 (7) in standing ropes, more than two broken wires in one lay in section beyond end commotions or more than one broken wire at an end connection. WRTB- replace wire ropes based on a number of broken wires. Standing ropes-3 in one lay or 2 at an end connection {in table on page 4}.

Record: 10-412 Committee: B30.5 Sub-Committee Subject: B30.5-0.2.2 add definition of minimum breaking force Date: 02/ 25/10 B30.5-0.2.2 Add the following Definition: Minimum breaking force: the minimum load at which a new and unused wire rope will break when loaded to destruction in direct tension

B30.5 Errata Para. 5-3.2.1.5 (h) from the 2000 edition of B30.5 ___________________________________________________________________________________________________ Existing in 2007 edition:

(h) Any time outriggers are used, the outriggers shall be extended or deployed per the crane manufacturer's load/capacity chart specifications and set to remove the machine weight from the wheels, except for locomotive cranes. [For locomotive cranes, refer to para. 5-3.2.1.5(j).]

The following was missing from this paragraph:

"When outrigger floats are used, they shall be attached to the outriggers. Blocking under outrigger floats, when required, shall meet the following requirements. (1) Sufficient strength to prevent crushing, bending, or shear failure. (2) Such thickness, width, and length as to completely support the float, transmit the load to the supporting surface, and prevent shifting, toppling, or excessive settlement under load. (3) Use of blocking only under the outer bearing surface of the extended outrigger beam."

The paragraph will continue: " When partially extended outriggers are used, the following requirements, when applicable, shall be met..."
