Hybrid stranded conductor
A hybrid strand includes a core and outer wires arranged around the core, wherein at least a part of the outer wires is compressed, wherein the compressed outer wires include a flattened cross-sectional shape, the outer wires are composed of steel, and the core is a fiber core. A corresponding production method produces such a hybrid strand.
Steel cable
A steel cable includes steel wires and at least one light wave guide which is surrounded by the steel wires and provided for detecting load-dependent cable strains, and has a glass fiber surrounded by a plastic casing. At least the steel wires closest to the light wave guide are crimped with the light wave guide and permanently pressed against the casing surface thereof, whereby the cross-sectional shape of the casing surface of the light wave guide deviates from an unloaded shape, in particular a circular shape, and the light wave guide is clamped continuously along at least one part of the longitudinal extension thereof, in a slip-free manner between the steel wires closest to same. A method produces a steel cable of this type.
COMPACTED STEEL STRAND WITH CLADDED CORE
A steel strand (10) comprises a steel core wire (12). This steel core wire (12) is surrounded by steel layer wires (14) that are twisted around the steel core wire (12). The steel core wire (12) is covered with a thick corrosion resistant core coating (16) provided by strip cladding or by metal extrusion. The steel layer wires (14) are covered with a thin corrosion resistant layer coating (18) provided by a hot dip operation or by an electroplating or chemical plating process. The steel strand (10) is compacted so that said steel layer wires (14) have a non-circular cross-section and that the thick corrosion resistant core coating fills the interstices between the steel core wire (12) and the steel layer wires (14) in order to give the steel strand (10) an improved corrosion resistance and increased lifetime.
Splitting method
A method is provided for manufacturing at least first and second assemblies of M1 filamentary elements and M2 filamentary elements. At least one of the first and second assemblies includes a plurality of filamentary elements wound together in a helix. The method includes a step of assembling M filamentary elements together into a layer of the M filamentary elements around a temporary core, to form a temporary assembly. The method also includes a step of splitting the temporary assembly into at least the first and second assemblies of M1 filamentary elements and M2 filamentary elements.
STEEL CABLE
A steel cable includes steel wires and at least one light wave guide which is surrounded by the steel wires and provided for detecting load-dependent cable strains, and has a glass fiber surrounded by a plastic casing. At least the steel wires closest to the light wave guide are crimped with the light wave guide and permanently pressed against the casing surface thereof, whereby the cross-sectional shape of the casing surface of the light wave guide deviates from an unloaded shape, in particular a circular shape, and the light wave guide is clamped continuously along at least one part of the longitudinal extension thereof, in a slip-free manner between the steel wires closest to same. A method produces a steel cable of this type.
Method for producing a wire cable
A method for producing a wire cable with a core cable or core strand, the method including the steps of: prior to stranding an outer strand layer, applying an intermediate layer of a plastic material to the core cable or core strand; pressing the outer layer into the plastic material during stranding; and, hammering the wire cable, after the outer strand layer has been stranded, to increase the space factor of the wire cable, wherein the hammering step includes hammering with hammers that are moved from different sides toward the wire cable and essentially completely surround the wire cable with adapted curvatures at the instant of their simultaneous impact.
Steel Cord for Tire Belt Ply Reinforcement
A steel cord for tire belt ply reinforcement includes a cord formed by periodically twisting n wires, wherein the n wires are compressed by rolling, and at least one of the n wires is compressed into a non-circular shape, when n is an odd number, a cross-section of one wire from among the n wires is circular due to rolling, and cross-sections of n?1 wires from among the n wires are non-circular, and when n is an even number, cross-sections of two wires from among the n wires are circular due to rolling, and cross-sections of n?2 wires from among the n wires are non-circular due to rolling.
Aircraft Mounted Hoist System Having a Multi-Stranded Wire Rope Cable
A hoist system includes a wire rope cable having a first end and a second end. The wire rope cable further including multiple strands twisted into a helical shape. The hoist system further including a lifting mechanism configured to attach to the first end of the wire rope cable. The lifting mechanism including at least one of a rotating drum and a set of frictional rollers. The hoist system further including a motor configured to rotate the lifting mechanism; and a housing configured to house the lifting mechanism, the motor, and at least part of the wire rope cable.
Wire cable and method and device for production of said wire cable
A wire cable and a device and method for producing the wire cable, wherein a core strand is compacted and then braid strands are stranded on the core strand. The core strand is hammered before stranding of the braid strands in order to smooth the surface thereof. A plastic layer is applied to the core strand before stranding of the braid strands. The braid strands are pressed into the plastic layer while the plastic layer is heated. The core strand is a core cable and the braid strands are strands of the wire cable or the core strand is a heart strand and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable is obtained by hammering the core strand in order to smooth it than by compacting a core strand with a roller compressor.
Wire
An operating wire has a multi-twisted structure constituted by twisting side strands, each formed by twisting element wires together around a core strand. A side element wire of the side strand faces the outside of the operating wire in the radial direction at a site located on the outer circumference of the operating wire and has a flattened surface where a flat portion provided in a portion of the side element wire in the circumferential direction extends in the X axis direction, the length in the X axis direction of the flattened surface being 4.8-11.0 times the diameter of the side element wire, and the pitch magnification of the side strand being 7.0-12.0 times the diameter.
