Within the generai scope defined in Section i of the Introduction, the scupe of B30.19 applies 10 all load transporing, hoisting, and lowering cabie -supported systems opecrating on and suported from track cable(s).
This Standard does not apply to skyline systems, as used in the logging industry, or stlacktine systems used for excavating-
Section 19-0.2: Definitions
19-0.2.1 Types of Cableways fired cubleway. a cableway consisting of fixed (non-luffing) towers (masts) which support the track cable(s).
The lower and upper load blocks are supported by a carriage powered by inhaul and outhaul ropes to travel on the track cable(s). The function is to lift, loweer, and transport loads a distance between the towers (see Fig. 1).
luffing cableway: a cableway similar to a fixed cableway except the towers (masts) are not fixed. By the use of powered lutting guys. the towers (masts) can be leaned in either drection transverse to the track cable[s) span, providing a lateral movement of the load biock (see Fig. 2).
parallel cableway: a cableway similar to a fixed cableway except the lowers are supponed by wheels which are powered for lateral movement on parallel Liacks (see Fig. 3).
radial cableway: a cableway which has a fixed (n1011- luffing) tower and a tower supported by wheels powered for travel on a track which follows an arc at a radius
about the fixcd tower (scC Fig. 4).
19-0.2.2 Generai
accessory: a secondary part or assembly of parls that contribules 10 the overall function and usefulness of the machine.
