16、production or networking permitted without license from IHS-,-,-FOREWORDThis American National Standard, Safety Standard for Cableways, Cranes, Derricks, Hoists,Hooks, Jacks, and Slings, has been developed under the procedures accredited by the AmericanNational Standards Institute (formerly the Unit

17、ed States of America Standards Institute). ThisStandard had its beginning in December 1916 when an eight-page Code of Safety Standards forCranes, prepared by an ASME Committee on the Protection of Industrial Workers, was presentedto the annual meeting of the ASME.Meetings and discussions regarding s

18、afety on cranes, derricks, and hoists were held from 1920to 1925, involving the ASME Safety Code Correlating Committee, the Association of Iron andSteel Electrical Engineers, the American Museum of Safety, the American Engineering StandardsCommittee (later changed to American Standards Association a

19、nd subsequently to the USAStandards Institute), Department of Labor State of New Jersey, Department of Labor andIndustry State of Pennsylvania, and the Locomotive Crane Manufacturers Association. OnJune 11, 1925, the American Engineering Standards Committee approved the ASME Safety CodeCorrelating C

20、ommittees recommendation and authorized the project with the US Departmentof the Navy, Bureau of Yards and Docks, and ASME as sponsors.In March 1926, invitations were issued to 50 organizations to appoint representatives to aSectional Committee. The call for organization of this Sectional Committee

21、was sent out October2, 1926, and the committee organized November 4, 1926, with 57 members representing 29 nationalorganizations. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943, was createdfrom the eight-page document referred to in the first paragraph. This document was reaffirmed

22、in 1952 and widely accepted as a safety standard.Due to changes in design, advancement in techniques, and general interest of labor and industryin safety, the Sectional Committee, under the joint sponsorship of ASME and the Naval FacilitiesEngineering Command, US Department of the Navy, was reorgani

23、zed as an American NationalStandards Committee on January 31, 1962, with 39 members representing 27 national organiza-tions.The format of the previous code was changed so that separate standards (each complete as toconstruction and installation; inspection, testing, and maintenance; and operation) w

24、ould coverthe different types of equipment included in the scope of B30.In 1982, the Committee was reorganized as an Accredited Organization Committee, operatingunder procedures developed by the ASME and accredited by the American National StandardsInstitute.This Standard presents a coordinated set

25、of rules that may serve as a guide to governmentand other regulatory bodies and municipal authorities responsible for the guarding and inspectionof the equipment falling within its scope. The suggestions leading to accident prevention aregiven both as mandatory and advisory provisions; compliance wi

26、th both types may be requiredby employers of their employees.In case of practical difficulties, new developments, or unnecessary hardship, the administrativeor regulatory authority may grant variances from the literal requirements or permit the use ofother devices or methods, but only when it is cle

27、arly evident that an equivalent degree ofprotection is thereby secured. To secure uniform application and interpretation of this Standard,administrative or regulatory authorities are urged to consult the B30 Committee, in accordancewith the format described in Section III, before rendering decisions

28、 on disputed points.Safety codes and standards are intended to enhance public safety. Revisions result from commit-tee consideration of factors such as technological advances, new data, and changing environmentaland industry needs. Revisions do not imply that previous editions were inadequate.This v

29、olume of the Standard, which was approved by the B30 Committee and by ASME, wasapproved by ANSI and designated as an American National Standard on September 28, 2005.ivCopyright ASME International Provided by IHS under license with ASME Not for ResaleNo reproduction or networking permitted without l

38、cope of B30.19 applies to all load trans-porting, hoisting, and lowering cable-supported sys-tems operating on and supported from track cable(s).This Standard does not apply to skyline systems, as usedin the logging industry, or slackline systems used forexcavating.SECTION 19-0.2: DEFINITIONS19-0.2.

39、1 Types of Cablewaysfixed cableway: a cableway consisting of fixed (nonluffing)towers (masts) that support the track cable(s). The lowerand upper load blocks are supported by a carriage pow-ered by inhaul and outhaul ropes to travel on the trackcable(s). The function is to lift, lower, and transport

40、 loadsa distance between the towers (see Fig. 1).luffing cableway: a cableway similar to a fixed cablewayexcept the towers (masts) are not fixed. By the use ofpowered luffing guys, the towers (masts) can be leanedin either direction transverse to the track cable(s) span,providing a lateral movement

41、of the load block(see Fig. 2).parallel cableway: a cableway similar to a fixed cablewayexcept the towers are supported by wheels that are pow-ered for lateral movement on parallel tracks (see Fig. 3).radial cableway: a cableway that has a fixed (nonluffing)tower and a tower supported by wheels power

42、ed fortravel on a track that follows an arc at a radius aboutthe fixed tower (see Fig. 4).19-0.2.2 Generalaccessory: a secondary part or assembly of parts thatcontributes to the overall function and usefulness of themachine.administrative or regulatory authority: governmentalagency, or the employer

43、in the absence of governmentaljurisdiction.appointed: assigned specific responsibilities by theemployer or the employers representative.1authorized: approved by a duly constituted administra-tive or regulatory authority.brake: a device, other than a motor, used for retardingor stopping motion by mea

44、ns of friction or power.button line: a rope suspended between the top of thecableway towers to position the slack carriers at prede-termined locations as the trolley moves longitudinallyalong the track cable. The button line is normally aboveand clear of the track cables. The buttons attached tothe

45、button line are of varying sizes to permit some ofthe slack carriers to pass by while stopping the carrierdesignated for that location.cab: a housing provided for the operator in which thecableway controls are contained.cableway: a device used for hoisting, lowering, and trans-porting loads within a

46、 prescribed path, longitudinallyand laterally. The load block (upper) travels on a ropecatenary system having span ends that are supportedon fixed or movable towers (masts) or other elevatedsupports.carriage (trolley): a framework that travels by its sheaves(wheels) on the track cable(s) and include

47、s the upperload block.designated: a person selected or assigned by the employeror the employers representative as being competent toperform specific duties.designer (original): the qualified person or persons desig-nated to design the components of a cableway for agiven set of circumstances relating

48、 to, but not limitedto, capacity, span, height, and terrain (also, see manufac-turer).designer (other than original): the qualified person or per-sons designated to modify the design or arrangementof an existing cableway to a new set of circumstances.design factor, rope: the ratio of nominal breakin

49、g strengthto working load.drift: the act of pulling or pushing the lower load blockor load horizontally by means of an external force.Copyright ASME International Provided by IHS under license with ASME Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-ASME B30.19-2005 CABLEWAYSFig.1FixedCableway2Copyright ASME Internati
