ASME B30.19:2005 pdf download Cableways Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings
8ypsy spool (vinch ead): a rotating cylindrical drum withcurved end flanges used for load handling by meansof fiber rope coiled about its barrel with hand tensionapplied to the nonloaded end.
head towwer (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.
inhael-outhaul (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).irhaul-outhatel hoist (trolley hoist): 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 (see Figs. 5,6,and 7). The hoist is powered by a prime mover.
lazy guy: fixed length member(s) of rope that preventsluffing the tower(s) (mast) beyond the distance estab-lished by the luffing hoist (a safety device).
load, miaximun 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, zsorking: the external load applied to the cablewaylower load block, including the weight of load attachingequipment such as shackles, slings, etc.
load block , 8orver: the assembly of hook or shackle, swivel,sheaves, pins,and framesuspended 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.
load hoist: a hoist drum and rope reeving system usedfor hoisting and lowering loads.
loced ratings: working load rating in pounds (kilograms)or tons established by the designer.
lueffing: the tilting of the cableway towers to achievemovement of the load block transverse to the center lineof the cableway.
luffing hoist: the hoist drum and rope reeving systemused for luffing a cableway tower (mast)(see Fig.8).manufacturer: 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 line: an auxiliary rope suspended between thetowers of the cableway to intermittently support electric power cables or other cables.The messenger line is nor-mally at the very top of the towers, above and clear ofthe button line.
operating ropes: wire ropes attached to a hoist for thepurpose of pulling or lifting.
ooerhaul: the action of pulling on a rope or set of fallsto remove slack and unwind the rope from the hoistdrum.
pitch diaeter: 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 each situ-ation.
slack carrier: a device that travels on the track cable tosupport the operating ropes when they are slack.
tail fover (mast): 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.
fon,long: 2,240 lb.
fon, short: 2,000 lb.
frack cable; the rope(s),spanning between the towers,thatsupports the trolley, load blocks, slack carriers,and load.frolley: a carriage traveling on the track cable from whichthe load blocks are supported.The trolley is pulled alongthe track cable by the inhaul-outhaul rope.
tzoo-blocking: the condition in which the lower load blockor hook assembly comes in contact with the upper loadblock.
