Wire rope in which the wires in the strands and the strands in the rope are laid in the same direction. |
|
Lashing |
Wire rope, synthetic rope, synthetic webbing, or other approved material. (Without permanent end fittings) that is used for wrapping and securing around an object to provide a point or points from which to lift the object, or attaching to an approved structure to serve as a point from which to rig. |
|
Lay |
Manner in which wires are helically laid into strands or strands into rope. |
|
Lay length of wire rope |
The distance along a wire rope in which a strand makes one complete turn around the ropes center. |
|
Lay left |
Strand-strand in which the cover wires are laid in a helix having a left hand pitch, similar to a left hand screw. Rope - rope in which the strands are laid in a helix having a left hand pitch, similar to a left hand screw. |

Wire rope fitting consisting of a "basket" and two "ears" with a pin. |
|
Parcelling |
Narrow strips of canvas which are wound around ropes for protection. |
|
Preformed strand |
Strand in which the wires are permanently shaped, before fabrication into the strands, to the helical form they assume in the wire rope |
|
Preformed wire rope |
Wire rope in which the strands are permanently shaped, before fabrication into the rope, to the helical form they assume in the wire rope |
|
Pre-stressing |
Stressing a wire rope or strand before use under such a tension and for such a Time that the constructnal stretch is largely removed |
|
Re-certification date |
The last day you may use the equipment without performing and recording a complete visual inspection of the handling equipment, or a load test and visually inspecting lifting equipment. |
