Abstract
The invention relates to a rope made of a textile fibre material for applications in which a diagonal pull may occur, characterized in that the rope is a core/sheath rope the core (1) of which and the sheath of which are composed essentially of a textile fibre material the core (1) of which is stranded and which exhibits a force-fitting winding with a tensile element (2, 2′, 2″) between the core (1) and the sheath.
Claims19
A rope made of a textile fibre material for applications in which a diagonal pull may occur, the rope comprising:
- a core/sheath rope comprising a core and a sheath;
- and
- a tensile element,
- wherein the core and the sheath are composed essentially of a textile fibre material,
- wherein the core is stranded or braided,
- wherein the core, and/or, if the core is provided in the form of several strands, at least part of the strands, is/are wrapped by a first winding layer of the tensile element in a force-fitting manner, wherein the first winding layer contacts the core and/or the strands over an entire coincident length of the first winding layer with the core and/or strands,
- wherein, within the first winding layer formed by the tensile element, a winding is located with a longitudinally extending gap (L1, L2) from the next winding,
- wherein the diameter of the rope is at least 6 mm, and
- wherein the material of the core of the rope is comprised of high-strength fibres selected from the fibre types UHMWPE, aramid, LCP, PBO, and mixtures thereof.
A method of using a rope for an application in which a diagonal pull may occur, the method comprising:
- providing a rope made of textile fibre material, the rope comprising:
- a core/sheath rope comprising a core and a sheath,
- wherein the core and the sheath are composed essentially of a textile fibre material,
- wherein the core is stranded or braided,
- wherein the core, and/or, if the core is provided in the form of several strands, at least part of the strands, is/are wrapped by a tensile element in a force-fitting manner,
- wherein the tensile element contacts the core and/or the strands over an entire coincident length of the tensile element with the core and/or the strands,
- wherein, within a winding layer formed by the tensile element, a winding is located with a longitudinally extending gap (L1, L2) from the next winding,
- wherein the diameter of the rope is at least 6 mm, and
- wherein the rope omits any material suitable for the transmission of electrical signals;
- and
- using the rope as a suspension/hauling rope in a crane, tower slewing crane, mobile crane, crawler crane, offshore crane, or hoisting winch, for
- single-strand lifting of an unguided load, and/or
- in construction equipment, drilling equipment, ramming equipment, or cable dredges.
