Connector for synthetic and coated wire rope

a technology of synthetic and coated wire rope, applied in the field of methods, can solve the problems of high cost, high labor intensity, time-consuming and labor-intensive manual methods, and the current system of terminating synthetic rope often falls well short of the tensile strength of the rope using one splice, and achieves the effect of greater gripping length

Benefits of technology

This patent is about a new type of sleeve that has a special channel for crimping rope. This channel makes it easier to grip the rope and the sleeve, which helps to make the connection more secure.

Problems solved by technology

This manual method is very labor-intensive, time-consuming, and expensive.
The chemicals used during this process are also very expensive.
Current systems for terminating synthetic rope often fall well short of matching the tensile strength of the rope using one splice.
To obtain a splice on a synthetic rope that meets the tensile strength of the synthetic rope, multiple splices must be used which results in increasing both material and labor costs.

Embodiment Construction

[0035]The present disclosure relates to crimping sleeves. More particularly, it relates to a trilobular sleeve which provides three channels for crimping wire rope, such as synthetic rope or coated wire rope.

[0036]The disclosure in particular relates to a sleeve that is trilobular; that is, a sleeve that provides three channels for gripping synthetic or coated wire rope. On a first end of the wire rope can be a traditional eye splice and a thimble positioned within the eye splice. The thimble improves the holding capacity of the eye splice even further. On a second opposite end of the rope is a simple, very tight loop. This is a result of feeding the rope through two channels in the trilobular sleeve. The extra length of crimped rope in the third channel provides significantly greater holding force in the crimp. Basically the trilobular sleeve provides extra grip length.

[0037]Referring now to FIG. 1, a sleeve 10 is shown in accordance with a preferred embodiment of the present discl...

Abstract

A sleeve for terminating synthetic rope and coated wire rope has a body and a first channel, a second channel, and a third channel formed within the body. Each of the first, second, and third channels form a trilobular opening within the sleeve for receiving and crimping wire rope. The wire rope can have an eye splice formed at one end. A method of crimping the trilobular sleeve includes feeding the rope through the first channel of the trilobular sleeve, looping the rope through the second channel of the sleeve and then through the third channel of the trilobular sleeve, inserting the sleeve between upper and lower crimp dies, and pressing the sleeve between the dies, thereby crimping the sleeve to the rope.

Description

CROSS REFERENCE TO RELATED APPLICATIONS AND CLAIM OF PRIORITY[0001]This application is a continuation of co-pending U.S. patent application Ser. No. 14 / 621,683 filed on Feb. 13, 2015, which claims priority from and benefit of the filing date of U.S. Provisional Patent Application No. 61 / 939,831 filed on Feb. 14, 2014, and the entire disclosure of each of said prior applications is hereby expressly incorporated by reference into the present specification.BACKGROUND OF THE DISCLOSURE[0002]There are several existing methods for splicing synthetic or coated wire rope. One method is to unweave and loosen the rope then re-weave the rope from separate bundles into a splice. This manual method is very labor-intensive, time-consuming, and expensive.[0003]A second method for splicing wire rope is to add a chemical to the wire bundles to fuse them together along with a sleeve. The chemicals used during this process are also very expensive.[0004]A third method which is an aspect of the present ...
