Abstract
A novel cable construction provided an armored covering over a cable containing high-strength synthetic filaments. The synthetic cable is provided with a strong and tough termination where it attaches to heavy machinery, such as mining machinery. An external armoring is then provided for a desired portion of the cable (up to the entire length of the cable). A collar is preferably provided to seal the end of the armoring portion to a cable jacket (where a cable jacket is present).
Claims8
A mining machine for scooping material, comprising:
- a. a cab;
- b. a boom extending to a point sheave;
- c. a bucket assembly;
- d. a lift rope extending from said bucket assembly over said point sheave and to said cab, said lift rope being wrapped around a hoist drum;
- e. said lift rope configured to cycle between a low position in which said bucket assembly is in a low position and a high position in which said bucket assembly is in a high position;
- f. said lift rope including a wire rope portion wrapped around said hoist drum and extending out to a wire rope junction, and a synthetic portion extending from said wire rope junction over said point sheave to proximate said bucket assembly;
- g. wherein said wire rope junction lies between said hoist drum and said point sheave when said bucket assembly is in said low position and said high position;
- and
- h. cable armoring on said lift tope, extending from proximate said bucket assembly up to a level below said point sheave when said bucket assembly is in said high position.
