A rope system (10, 20) comprising a splice structure (12, 22) with an intact portion (23) comprising at least 8 intact strands (32, 34), and a disassembled portion (26) comprising at least 4 loose strands (30), wherein the intact portion (23) is a braid of at least 4 S oriented (32) and at least 4 Z oriented intact strands (34), wherein at least one loose strand (30) of the disassembled portion (26) passes under and over intact strands (32, 34) of the intact portion (23), and at least one loose strand (30) passes under at least one X-tuck (38) of intact strands (32, 34). By this means the splice length can be minimized resp. slippage of the splice at high loads can be avoided.

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.

There are provided a rope which is excellent in a wear resistance and a bending resistance, and a manufacturing method of implementing the rope.

A rope (1) including a yarn twisted by using a raw thread (5) of a polyethylene fiber (6) having an ultrahigh molecular weight and a strand (2) twisted by the yarn and subjected to steel-making through the strand (2), and a resin coating layer for protecting the rope (1) is formed on an external surface of the yarn, an external surface of the strand (2) or an external surface of the rope (1). A method of manufacturing the rope (1) includes a pretreating step I of removing an oil content contained in the rope (1) and performing an affinity enhancing treatment over a surface thereof and a resin coating step II of forming a resin coating layer for protecting the rope (1) on an external surface of the yarn, an external surface of the strand (2) or an external surface of the rope (1). The resin coating layer for protecting the rope (1) is formed. For this reason, impurities such as sand in the sea or the like is prevented from intruding into an inner part of the rope (1). Therefore, a life of the rope (1) can be enhanced.

Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope that has greater resilience to high heat temperatures resultant of use with powered blocks and/or sheaves and has a longer service life in comparison to known synthetic rope constructions. The rope of the present disclosure has multiple distinct synthetic substances each forming distinct components that work together to, surprisingly, increase tolerance to bending fatigue of the rope and especially to high heat temperatures resultant of use with powered blocks and/or sheaves in comparison to known synthetic ropes.

A reinforcing cord for rubber reinforcement of the present invention that is used for reinforcing a rubber product is provided with a plurality of strands. The strand includes bundled fibers and a coating layer formed so as to cover the bundled fibers. The plurality of strands are in tight contact with one another via the coating layer. The coating layer contains a material that is crosslinkable by thermal treatment. A method of manufacturing the reinforcing cord for rubber reinforcement includes the steps of (i) forming strands that include bundled fibers and a coating layer formed so as to cover the bundled fibers, and (ii) bringing the strands into tight contact with one another via the coating layer by twisting the strands together. The coating layer contains a material that is crosslinkable by thermal treatment.

Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope, comprising multiple layers of twisted and braided yarns, wherein individual sheaths enclosing individual strands are of a material such as HMPE, PTFE or UHMWPE with a lower decomposition temperature than the material of said strands being aramid, the method comprising subjecting parts of the rope to heat and tension thereby pre-stretching and creating a non-uniform or non-round shape of said strands, further choosing a combination of braid and twist angles as well as braid compressive forces to accommodate specific strength and elongation relation between the individual rope layers.

Provided is a double rope structure which is provided with an inner core and an outer cover. In the double rope structure, the inner core includes high strength and high modulus fibers with a yarn tenacity of 20 cN/dtex or higher and a yarn elastic modulus of 400 cN/dtex or higher, and has a ratio of yarn length/rope length of 1.005 or more and 1.200 or less, the rope length being determined as a length of a cut section (V) cut to a certain length from the rope structure, and the yarn length being determined as an average value of lengths of yarns constituting the inner core of the cut section (V).

The rope of the present disclosure has multiple distinct synthetic substances each forming distinct components that work together to, surprisingly, increase tolerance to bending fatigue of the rope and especially to high heat temperatures resultant of use with powered blocks and/or sheaves in comparison to known synthetic ropes.

A wire rope for face shovels or draglines, comprising: a core, said core is made from a plurality of core strands a plurality of outer strands laid on said core, a plurality of separator strands located in the interstices between said core strands and said outer strands, a plastic jacket around said plurality of outer strands, said plurality of separator strands and said core strands, wherein said plurality of separator strands extend from said core strands and in-between each pair of said plurality of outer strands so as to produce and maintain gaps between said pair of said plurality of outer strands; wherein said core strands are compacted, and the gap between said core strands is less than 0.4% of the diameter of the core strand.

A belt for carrying an elevator car and/or a counterweight of an elevator system includes a belt body with a traction side for contacting a traction sheave of the elevator system and a back side opposite the traction side. The belt body has a groove profile on the traction side adapted to an outer contour of the traction sheave, and has a profile on the back side deviating from the groove profile. Multiple tension members are embedded in the belt body for transmitting tensile forces, wherein each tension member is formed by multiple strands twisted together, and each strand is formed by multiple aramid fibers twisted together.
