Abstract
Abstract A cableway arrangement comprising a driveway formed from at least one cable, and at least one support cable. The driveway is stressed and further is preloaded by the support cable through the agency of connection element means between each two supports limiting a span zone in a manner producing a negative sag when the driveway is not subjected to the load of the payload. The preloading is such that the payload guided along the driveway, and against the action of the preloading of the driveway produced by the negative sag, follows a direction of travel which approximates a straight line.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
A cableway arrangement for moving a payload comprising at least an elongated driveway, at least one support cable, spaced support means positioned apart to form at least one span, said driveway and said cable extending between and being attached at the ends of said span to said spaced support means, connection element means interposed between said driveway and said support cable for preloading the driveway, such that under no load said driveway has a negative sag along said span, and said driveway being stressed sufficiently by said connection element means under no load to generate negative bearing forces at said support means.
Claim 2
Dependent Claim
102 words
A cableway arrangement for moving a payload comprising at least an elongated driveway, at least one support cable, spaced support means positioned apart to form at least one span, said driveway and said cable extending between and being attached at the ends of said span to said spaced support means, connection element means interposed between said driveway and said support cable for preloading the driveway, such that under no load said driveway has a negative sag along said span, and said driveway being stressed sufficiently by said connection element means under no load to generate negative bearing forces at said support means.
Claim 3
Dependent Claim
129 words
A cableway arrangement for moving a payload, comprising at least one stressed cable forming a driveway, at least one support cable, connection element means interposed between said driveway and said support cable for preloading the driveway via said support cable such that under no load each span has a negative sag, and wherein when a payload is guided along the driveway such payload, against the action of the preloading of the driveway produced by the negative sag, follows a direction of travel which approximates a straight line, a plurality of spaced support means for said cableway arrangement and respectively defining therebetween each said span, and wherein the force exerted upon said support means by said driveway during a no load condition of each span corresponds to the average payload.
Claim 4
Dependent Claim
129 words
A cableway arrangement for moving a payload, comprising at least one stressed cable forming a driveway, at least one support cable, connection element means interposed between said driveway and said support cable for preloading the driveway via said support cable such that under no load each span has a negative sag, and wherein when a payload is guided along the driveway such payload, against the action of the preloading of the driveway produced by the negative sag, follows a direction of travel which approximates a straight line, a plurality of spaced support means for said cableway arrangement and respectively defining therebetween each said span, and wherein the force exerted upon said support means by said driveway during a no load condition of each span corresponds to the average payload.
Claim 5
Dependent Claim
108 words
A cableway arrangement for a moving payload, comprising at least one stressed cable forming a driveway, at least one support cable, connection element means interposed between said driveway and said support cable for preloading the driveway via said support cable such that under no load each span has a negative sag, and wherein when a payload is guided along the driveway such payload, against the action of the preloading of the driveway produced by the negative sag, follows a direction of travel which approximates a straight line, and wherein said stressed cable forming said driveway possesses a tensional load which is approximately twice that of said support cable.
Claim 6
Dependent Claim
108 words
A cableway arrangement for a moving payload, comprising at least one stressed cable forming a driveway, at least one support cable, connection element means interposed between said driveway and said support cable for preloading the driveway via said support cable such that under no load each span has a negative sag, and wherein when a payload is guided along the driveway such payload, against the action of the preloading of the driveway produced by the negative sag, follows a direction of travel which approximates a straight line, and wherein said stressed cable forming said driveway possesses a tensional load which is approximately twice that of said support cable.
