Abstract
A contact-connecting device connects more than two indicator fibers in an electrically conducting manner to create a conducting connection of the indicator fibers at the end of a safety-monitored synthetic fiber rope made from electrically insulating synthetic fibers and the electrically conducting indicator fibers. A fastener fixes the contact-connecting device and the indicator fibers relative to one another, which creates a low-cost and reliable contact-connection.
Claims14
A method for contact-connecting a safety-monitored rope comprsing the steps of:
- a. providing a rope having at least one strand constructed from a first plurality of electrically insulating synthetic fibers and a second plurality of electrically conducting indicator fibers, at least Flee of the indicator fibers extending to an end of the rope;
- and
- b. connecting the at least three indicator fibers together in an electrically conducting manner with a contacting element fastened to the end of the rope.
A synthetic fiber rope comprising:
- a first plurality of electrically insulating synthetic fibers twisted together to form a twisted stranded rope;
- a second plurality of electrically conducting indicator fibers arranged parallel to and twisted together with said insulating fibers, at least three of said indicator fibers extending to an end of said rope;
- and
- a contacting means attached to said end of said rope for connecting said at least three of said indicator fibers together in an electrically conducting manner.
1 more element
A safety-monitored synthetic fiber rope comprising:
- a plurality of strands of twisted together electrically insulating synthetic fibers and electrically conducting indicator fibers;
- and
- a contact-connecting device attached to an end of the rope in electrically conducing contact with more than two of said indicator fibers.
