The invention relates to a sensor device for insertion and for measuring tension within a braided, plaited and/or laid line. The sensor device comprises an elongated sensor housing having an outer housing surface and an inner housing surface and at least one pressure sensor arranged inside the elongated sensor housing. The outer housing surface having a substantially elliptic or circular cross sectional area around the longitudinal axis of the sensor housing. Further, the at least one pressure sensor is configured to allow measurement, at least indirectly, of a pressure exerted on the outer housing surface. The invention also relates to a line sensor assembly for mooring of one or more structures, and a method of adjusting the tension in a line sensor assembly and the use of a line sensor assembly.

An elevator installation and method to passively and reliably generate electrical energy while the elevator installation is in operation utilizes piezoelectric layers. The elevator installation includes an elevator car, a tension member for supporting and moving the elevator car, and a pulley engaging with the tension member wherein the pulley has a piezoelectric layer positioned such that any force imparted to the pulley during engagement with the tension member compresses the piezoelectric layer. As the tension member is driven to move the elevator car up and down along an elevator hoistway it also engages with the rotating pulley. Force imparted to the pulley during this engagement with the tension member compresses the piezoelectric layer which consequently generates electrical energy.

A wire strand (10) comprises a plurality of wires (12, 16, 20). The wires comprise a central king wire (12), a first layer (14) of wires (16) arranged around the king wire, and a second layer (18) of wires (20) arranged around the first layer. The king wire is formed of steel having a carbon content of at least 0.3 wt %. Each wire of the first layer is formed of steel having a carbon content which is less than the carbon content of the king wire. Each wire of the second layer is formed of steel having a carbon content which is greater than, or the same as, the carbon content of the wires of the first layer.

Aspects of the disclosure relate to a pulling device for pulling wire, cable, and/or duct products through an opening (e.g., bore, conduit, duct, etc.). The pulling device includes a gripping sleeve having a first end and a second end, the first end of the gripping sleeve configured to receive the product. The second end of the gripping sleeve is coupled with an eye, the eye configured to guide the pulling device through the opening. The pulling device further includes a cord configured to remove a protective material that can at least partially enclose the gripping sleeve and/or the product. The cord can be coupled to at least one of the gripping sleeve or the eye, and extend distally beyond the first end of the gripping sleeve.

In a rope of a lifting device, particularly of a passenger transport elevator and/or freight transport elevator, the width of which rope is greater than the thickness in the transverse direction of the rope, which rope includes a load-bearing part in the longitudinal direction of the rope, which load-bearing part includes carbon-fiber reinforced, aramid-fiber reinforced and/or glass-fiber reinforced composite material in a polymer matrix, and which rope includes one or more optical fibers and/or fiber bundles in connection with the load-bearing part and the optical fiber and/or fiber bundle is laminated inside the load-bearing part and/or the optical fiber and/or fiber bundle is glued onto the surface of the load-bearing part and/or and that the optical fiber and/or fiber bundle is embedded or glued into the polymer envelope surrounding the load-bearing part, as well as to a condition monitoring method for the rope of a lifting device.

An elevator installation and method to passively and reliably generate electrical energy while an elevator installation is in operation includes an elevator car, a tension member for supporting and moving the elevator car, and a pulley engaging with the tension member. Piezoelectric elements are applied to or embedded within the tension member. As the tension member is driven to move the elevator car up and down along an elevator hoistway, the tension member also engages with the rotating pulley. Force imparted to the tension member during this engagement with the pulley is transmitted to the piezoelectric elements which consequently generate electrical energy.

Provided is a cable including a stranded member floating-preventing element that can be easily peeled off.

A power transmission line core includes one core member and six side members twisted around the core member, each member obtained by impregnating a fiber bundle including a plurality of carbon fibers that are continuous in the longitudinal direction and bundled into the fiber bundle with a resin and curing the resin. A tow including a plurality of tow fibers that are continuous in the longitudinal direction and arranged flatly and densely is spirally wound around the surface of the power transmission line core in the direction opposite to the twisting direction of the side members. The tow is detachably entangled in the unevenness on the surface of the power transmission line core.

Provided is a wire rope with resin wire, including a wire rope body in which a plurality of strands are twisted together, and at least one resin wire spirally wound around the wire rope body along a recess between the strands. Strand grooves into which the strands can fit and a resin wire groove into which the resin wire can fit are formed spirally along the twist of the wire rope with resin wire, in a winding hole of a resin wire winding die used for winding the resin wire around the wire rope body. As a result, the resin wire can be easily and reliably mounted on the wire rope body and a wire rope with resin wire can be thus produced.

A method and device for producing a rope, in particular a wire rope, a fiber rope or a rope having wire and fibers, wherein the rope is provided with a marking during the stranding thereof. The marking is changed during the stranding operation. Expediently, during stranding, the marking is provided successively with details characterizing the stranding progress. The details include production parameters, for example information relating to the length of the rope already formed, about raw materials used, the stranding speed and/or the current stranding time. The details are provided on a wire, a wire strand and/or a marking strand, wherein the details are printed on the wire, the wire strand or the marking strand or are embossed in the wire, the wire strand or the marking strand, and/or chips, preferably radio chips, are arranged in the rope.

A method of wear detection of a coated belt or rope includes connecting a wear detection unit to one or more monitoring strands and/or cords of a coated belt or rope. The coated belt or rope includes one or more baseline strands and/or cords exhibiting a first change in electrical resistance as a function of bending cycles of the belt or rope and one or more monitoring strands and/or cords exhibiting a second change in electrical resistance as a function of bending cycles of the belt or rope, greater than the first change in electrical resistance. An electrical resistance of the one or more monitoring strands and/or cords is measured via the wear detection unit. Using at least the measured electrical resistance of the one or more monitoring strands and/or cords, a wear condition of the belt or rope is determined.
