Abstract
In various embodiments, an apparatus is disclosed comprising a platform, a hoisting machine mounted on the platform, and a rigging operable to raise and lower the elevator platform, said rigging passing through a fairlead, said fair lead stabilizing said elevator platform to a single location proximate a top of said elevator platform, said fairlead comprising two separable parts wherein said separable parts can be placed around said rigging without accessing an end of said rigging. Such a fairlead improves the serviceability of the equipment and reduce down time for replacement of a worn or damaged fairlead.
Claims38
An apparatus comprising:
- a platform;
- a hoisting machine mounted on the platform;
- a rigging operable to raise and lower the platform, said rigging further comprising a cable passing through a fairlead, said fairlead stabilizing said platform to a single location proximate a top of said platform, said fairlead comprising at least two separable parts wherein said each separable part further comprises fastening means and a radial gap on one side of said separable part.
A fairlead for guiding and securing a rigging used with a hoisting device in an elevator platform, said fairlead comprising at least two separable parts wherein said each separable part further comprises fastening means and a radial gap on one side of said separable part.
An apparatus for restraining rigging movement on an elevator platform for building maintenance, said elevator platform having a hoisting machine coupled to a rigging, said rigging passing through a fairlead, said fair lead stabilizing said elevator platform to a single location proximate a top of said elevator platform, said fairlead comprising at least two separable parts wherein said each separable part further comprises fastening means and a radial gap on one side of said separable part.
A method for replacing a fairlead used in an apparatus comprising a platform, a hoisting machine mounted on the platform, and a rigging operable to raise and lower the platform, said rigging passing through a fairlead, said fair lead stabilizing said platform to a single location proximate a top of said platform, said fairlead comprising at least two separable parts wherein said each separable part further comprises fastening means and a radial gap on one side of said separable part, the method comprising separating and removing a first pair of separable parts without accessing an end of said rigging, and installing a second pair of separable parts around said rigging without accessing an end of said rigging.
A method for replacing a fairlead used for guiding and securing a rigging used with a hoisting device in an elevator platform, said fairlead comprising at least two separable parts wherein said each separable part further comprises fastening means and a radial gap on one side of said separable part, the method comprising separating and removing a first pair of separable parts without accessing an end of said rigging, and installing a second pair of separable parts around said rigging without accessing an end of said rigging.
