head tower (mast): a vertical support structure, guyedor counterweighted for stability,whose purpose is tosupport the track cable and operating ropes. The headtower is the tower located closest to the load hoist andinhaul-outhaul hoist.
inhaxl-owthaul (rope): the rope system that pulls the trol-ley and load toward the head tower (inhaul), or pullsthe trolley and load away from the head tower (outhaul).inhaul-outhaal hoist (frolley oist): a hoist having twodrums,one of which winds on rope while the otherdrum simultaneously unwinds rope; or a single drumhoist from which the rope winds on one end while therope unwinds from the other drum end (seeFigs. 19-0.2.2-1,19-0.2.2-2,and 19-0.2.2-3).The hoist ispowered by a prime mover.
lazy guy: fixed length member(s) of rope that preventsluffing the tower(s) (masty beyond the distance estab-lished by the luffing hoist.
load, maximun design: the forces in a particular compo-nent of the cableway resulting from the loading condi-tion that causes the highest stress in that component.load, oorking: the external load applied to the cablewaylower load block , including the weight of load-attachingequipment such as shackles, slings, etc.
load block , locver: the assembly of hook or shackle, swivel,sheaves, pins,and frame suspended by the hoisting rope.load block , upper: the assembly of sheaves, pins,and framefrom which the hoisting rope suspends the lower loadblock.The block may be an integral part of the trolleyor suspended from the trolley.
loadd Joist: a hoist drum and rope reeving system usedfor hoisting and lowering loads.
load ratings: working load rating in pounds (kilograms)or tons established by the designer.
lxuffing: the tilting of the cableway towers to achievemovement of the load block transverse to the center lineof the cableway.
lxeffing hoist: the hoist drum and rope reeving systemused for luffing a cableway tower (mast) (seeFig.19-0.2.2-4).
maniefacturer: a firm that produces fabricated or assem-bled segments of the cableway. The segments include,but are not limited to, towers, ropes, track cable, trolley,hoists, and load blocks.
messenger lire: an auxiliary rope suspended between thetowers of the cableway to intermittently support electricpower cables or other cables.The messenger line is nor-mally at the very top of the towers, above and clear ofthe button line.
inimmunm breaking force: the minimum load at which anew and unused wire rope will break when loaded todestruction in direct tension.
operating ropes: wire ropes attached to a hoist for thepurpose of pulling or lifting.
ooerhael: the action of pulling on a rope or set of fallsto remove slack and unwind the rope from the hoistdrum.
pitch diameter: the diameter of a sheave or rope drummeasured at the center line of the rope.
qualified person: a person who, by possession of a recog-nized degree in an applicable field, or certificate of pro-fessional standing, or who, by extensive knowledge,training, and experience, has successfully demonstratedthe ability to solve or resolve problems relating to thesubject matter and work.
rope: refers to wire rope unless otherwise specified.rofation-resistant rope: a wire rope consisting of a layerof strand laid in one direction covered by a layer ofstrand laid in the opposite direction. This has the effectof counteracting torque and reducing the tendency ofthe finished rope to rotate.
shall: indicates that the rule is mandatory and must befollowed.
should: indicates that the rule is a recommendation, theadvisability of which depends on the facts in eachsituation.
slack carrier: a device that travels on the track cable tosupport the operating ropes when they are slack.
fail fowver (masf): a vertical support structure, guyed orcounterweighted for stability,the purpose of which isto support the track cable and operating ropes.The tailtower is the tower located furthest from the load hoistand inhaul-outhaul hoist.
thrust track: as support for a traveling tower, a rail(s)designed and constructed to withstand the horizontaland vertical resultant cableway forces perpendicular tothe direction of tower travel.
ton，long: 2,240 lb.
fon, shorE: 2,000 lb.
track cable: the rope(s). spanning between the towers, thatsupports the trolley, load blocks,slack carriers, and load.trolley: see carriage.
too-blocking: the condition in which the lower load blockor hook assembly comes in contact with the upper loadblock.
