Apparatus for supporting oppositely located sheave trains of an aerial ropeway comprising:
- a crossarm having a center portion and opposite side portions;
- apparatus for supporting said crossarm;
- first sheave train supporting apparatus;
- first pivot apparatus located on one of said opposite side portions for pivotally connecting said first sheave train supporting apparatus and said crossarm;
- second sheave train supporting apparatus;
- second pivot apparatus located on the other of said opposite side portions for pivotally connecting said second sheave train supporting apparatus and said crossarm;
- said first and second pivot apparatus being spaced apart a desired distance;
- a rigid elongated member having opposite end portions;
- third pivot apparatus for pivotally connecting one of said opposite end portions and said first sheave train supporting apparatus;
- and
- fourth pivot apparatus for pivotally connecting the other of said opposite end portions and said second sheave train supporting apparatus.
A method for supporting oppositely located sheave trains of an aerial ropeway comprising:
- supporting a crossarm having a center portion and opposite side portions;
- pivotally connecting first sheave train supporting apparatus at a first fixed location on one of said opposite side portions of said crossarm using a first pivot apparatus;
- pivotally connecting second sheave train supporting apparatus at a second fixed location on the other of said opposite side portions of said crossarm spaced from said first fixed location using a second pivot apparatus;
- pivotally connecting one end portion of an elongated member to said first sheave train supporting apparatus using a third pivot apparatus;
- and
- pivotally connecting another end portion of said elongated member to said second sheave train supporting apparatus using a fourth pivot apparatus.
Apparatus for controlling the sag in at least one moving haul cable of an aerial ropeway comprising:
- at least first and second support towers fixedly mounted a predetermined distance apart;
- at least two support cables spaced a predetermined distance apart and mounted on and extending between said first and second support towers;
- at least one crossarm having a first and second sheave train supporting apparatus mounted thereon and located between said at least first and second support towers;
- at least one moving haul cable passing through said first sheave train supporting apparatus in one direction and said at least one moving haul cable passing through said second sheave train supporting apparatus in the opposite direction;
- said at least one crossarm having opposite end sections;
- first securing apparatus for securing one of said opposite end sections to one of said at least two support cables;
- and
- second securing apparatus for securing the other of said opposite end sections to the other of said at least two support cables.
