Abstract
The flattened strand rope of the invention comprises wedge-shaped strands, each made up of wires wound on a core. At least a portion of the strand wires are fashioned as twisted wire groups in which the wires are sector-shaped and in contact with each other over helical surfaces. With such a structural embodiment of the flattened strand wire, use can be made of thin and, consequently, stronger and more flexible wires, thereby increasing the strength and flexibility of the rope and making for the use of the rope in the various branches of industry, including lifting mechanisms with large or small drum diameters.
Claims15
A rope comprising:
- at least one wedge-shaped strand;
- a core of said strands;
- wires wound on said core to form said strand;
- at least a portion of said strand wires fashioned as twisted wire groups;
- the wires in each one of said twisted wire groups being made sector-shaped and in contact with each other over helical surfaces;
- and,
- an intermediate layer of wires provided between said twisted wire groups of a strand and said core, the cross-sectional area of each one of said wires in said intermediate layer being close in value to the cross-sectional area of wires making up said twisted wire groups.
A rope comprising:
- at least one wedge-shaped strand;
- a core of said strands;
- wires wound on said core to form said strand;
- said strand wires being fashioned as twisted wire groups;
- the wires in each one of said twisted wire groups being made sector-shaped and in contact with each other over helical surfaces;
- an intermediate layer of wires provided between said twisted wire groups of a strand and said core.
A flattened strand rope comprising:
- several wedge-shaped strands wound on a central core;
- a core of each said strand;
- wires wound on said core of strand to form a strand;
- at least portion of said strand wires fashioned as twisted wire groups;
- the wires in each one of said twisted wire groups being made sector-shaped and in contact with each other over helical surfaces;
- and,
- an intermediate layer of wires provided between said twisted wire groups of a strand and said core, the cross-sectional area of each one of said wires in said intermediate layer being close in value to the cross-sectional area of wires making up said twisted wire groups.
