brake: a device, other than a motor, used for retarding or stopping motion by means of friction or power.
button line’: a rope suspended between the top of the cableway towers to position the slack carriers at predetermined locations as the trolley moves longitudinally along the track cable. The button line is normally above and clear of the track cables. The buttons attached to the button line are of varying sizes to permit some of the slack carriers to pass by while stopping the carrier designated for that location.
cab: a housing provided for the operator in which the cableway controls are contained.
cnbleway: a device used for hoisting, lowering, and transporting loads within a prescribed path. longitudinally and laterally. The load block (upper) travels on a rope catenary system having span ends that are supported on fixed or movable towers (masts) or other elevated supports.
carriage (trolley): a framework that travels by its sheaves (wheels) on the track cable(s) and includes the upper load block.
designated: a person selected or assigned by the employer or the employer’s representative as being competent to perform specific duties.
designer (original): the qualified person or persons designated to design the components of a cableway for a given set of circumstances relating to, hut not limited to, capacity, span, height, and terrain (also, see manufacturer).
designer (oilier than original): the qualified person or persons designated to modify the design or arrangement of an existing cableway to a new set of circumstances.
design factor, rope: the ratio of nominal breaking strength to working load.
drift: the act of pulling or pushing the lower load block or load horizontally by means of an external force.
gypsy spool (winch head): a rotating cylindrical drum with curved end flanges used for load handling by means of fiber rope coiled about its barrel with hand tension applied to the nonloaded end.
head tower (mast): a vertical support structure, guyed or counterweighted for stability, whose purpose is to support the track cable and operating ropes. The head tower is the tower located closest to the load hoist and inhaul-outhaul hoist.
inhaul-outiwul (rope): the rope system that pulls the trolley and load toward the head tower (inhaul), or pulls the trolley and load away from the head tower (outhaul).
inhaul-outhaul hoist (trolley hoist): a hoist having two drums, one of which winds on rope while the other drum simultaneously unwinds rope; or a single drum hoist from which the rope winds on one end while the rope unwinds from the other drum end (see Figs. 5, 6, and 7). The hoist is powered by a prime mover.
la:y guy: fixed length member(s) of rope that prevents luffing the tower(s) (mast) beyond the distance established by the luffing hoist (a safety device).
load, maximum design: the forces in a particular component of the cableway resulting from the loading condition that causes the highest stress in that component.
load, working: the external load applied to the cableway lower load block, including the weight of load attaching equipment such as shackles, slings, etc.
load block, lower: 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 frame from which the hoisting rope suspends the lower load block. The block may be an integral part of the trolley or suspended from the trolley.
load hoist: a hoist drum and rope reeving system used for hoisting and lowering loads.
load ratings: working load rating in pounds (kilograms) or tons established by the designer.
luffing: the tilting of the cableway towers to achieve movement of the load block transverse to the center line of the cableway.
luffing hoist: the hoist drum and rope reeving system used for luffing a cableway tower (mast) (see Fig. 8).
