SECTION 19-0.1: SCOPE OF B3019
Within the general scope defined in Section I of theIntroduction, the scope of B30.19 applies to all load transporting,hoisting,and lowering cable-supported systems operating on and supported from track cable(s)This Standard does not apply to skyline systems, as usecin the logging industry, or slackline systems used forexcavating
SECTION 19-0.2: DEFINITIONS
19-0.2.1 Types of Cableways
fixed 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 loadsa distance between the towers (see Fig. 1).
luffing cablewa: 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) spanproviding a lateral movement of the load block(see Fig.2)
parallel cableuay: a cableway similar to a fixed cablewayexcept the towers are supported by wheels that are powered for lateral movement on parallel tracks (see Fig. 3).radial cableray: a cableway that has a fixed (nonluffingtower and a tower supported by wheels powered fortravel on a track that follows an arc at a radius aboutthe fixed tower (see Fig. 4).
19-0.22 General
accessory: a secondary part or assembly of parts thatcontributes to the overall function and usefulness of themachine.
administrative or regulatory authority: governmentalagency, or the employer in the absence of governmentalurisdiction.
appointed: assigned specific responsibilities by theemployer or the employer’s representative.
authorized: approved by a duly constituted administra-tive or regulatory authority.
brake: a device, other than a motor, used for retardingor stopping motion by means of friction or power.button line: a rope suspended between the top of thecableway towers to position the slack carriers at predetermined locations as the trolley moves longitudinallyalong the track cable. The button line is normally aboveand clear of the track cables. The buttons attached tothe 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.
cablewaw: a device used for hoisting,lowering, and transporting loads within a 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 includes the upperload block.
designated: a person selected or assigned by the employeror the employer’s representative as being competent toperform specific duties.
designer (original): the qualified person or persons designated to design the components of a cableway for agiven set of circumstances relating to, but not limitedto, capacity, span, height, and terrain (also, see manufacfitrer).
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 breaking strengthto working load.
drift: the act of pulling or pushing the lower load blockor load horizontally by means of an external force.
