Abstract
A method for creating a composite cable having at least one high-performance termination on at least one end. A high-performance termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a “composite” cable having a high-performance termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.
Claims2
A method of creating a composite cable with a first advanced termination on a first end and a second advanced termination on a second end, wherein the performance of said advanced termination is pre-qualified, comprising:
- a. providing a first short cable, having a first end and a second end;
- b. locking said second end of said first short cable into a first advanced termination;
- c. after said second end of said first short cable is locked into said first advanced termination, applying a defined test load to said first short cable and said first advanced termination, wherein said defined test load is applied through said first advanced termination in order to determine whether said first short cable and said first advanced termination pass a defined test criterion;
- d. providing a second short cable, having a first end and a second end;
- e. locking said second end of said second short cable into a second advanced termination;
- f. after said second end of said second short cable is locked into said second advanced termination, applying a defined test load to said second short cable and said second advanced termination, wherein said defined test load is applied through said second advanced termination in order to determine whether said second short cable and said second advanced termination pass a defined test criterion;
- g. providing a long cable, having a plurality of strands, a first end and a second end;
- and
- h. joining said first end of said first short cable to said first end of said long cable and said first end of said second short cable to said second end of said long cable to form said composite cable having a first advanced termination and a second advanced termination.
A method of creating a composite cable with an advanced termination on one end for use on a crane including a top sheave, comprising:
- a. providing a short cable, having a length, a plurality of strands, a first end and a second end;
- b. locking said second end of said short cable into an advanced termination;
- c. defining said length of said short cable by its capacity to remain below said top sheave when said composite cable is applied to said crane;
- d. after said second end of said short cable is locked into said advanced termination, applying a defined test load to said short cable and said advanced termination, wherein said defined test load is applied through said advanced termination in order to determine whether said short cable and said advanced termination pass a defined test criterion;
- e. providing a long cable, having a plurality of strands, a first end and a second end;
- and
- f. interweaving said plurality of strands from said first end of said short cable to said plurality of strands from said second end of said long cable to form said
- composite cable having an interwoven section and a first advanced termination.
