Abstract:
An elevator system includes a car or platform to transport passengers and/or goods as well as a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is a sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material and a second layer with a connection plane formed between the first and second layers. At least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—is embedded in an area of the connection plane, a majority of a surface of said at least one tension member directly contacting said first layer. A manufacturing procedure for one of the suspension elements is provided.
Abstract:
A self-wrapping, textile sleeve for routing and protecting elongate members from exposure to abrasion, thermal and other environmental conditions and method on construction thereof. The sleeve has an elongate wall constructed from interlaced yarns having interstices between adjacent yarns. At least one of the yarns is heat formed at one temperature to form the wall as a self-wrapping wall curling about a longitudinal axis of the sleeve. The wall has an inner surface providing a generally tubular cavity in which the elongate members are received. The wall also has an outer surface with a cured layer thereon. The cured layer is cured at the one temperature at which the yarns are heat formed into their self-wrapping configuration, wherein the cured layer fills the interstices between adjunct yarns to form an impervious layer on the wall.
Abstract:
A strand (3) comprising a group of twisted threads (8) and arranged so as to have, over a first part (1) of its length: a sheath (4) containing the group of twisted threads, and a flexible filling product (7) filling a peripheral interstice (6) located between the inner face of the sheath and the periphery of the group of twisted threads, and, over a second part (2) of its length, which is separate from the first part: a material (9) covering the periphery of the group of twisted threads, said material adhering to the twisted threads of the group.
Abstract:
A flexible abrasion resistant water shedding omnidirectionally reflective rope has a central low-density polymeric closed cell foam core comprising EPDM, Neoprene, SBR, NBR, EVA, PVC, PVC/NBR foam surrounded by cylindrically braided sleeve of reflective strips composed of narrow width reflective strips that comprise a woven or knitted narrow width strip and a flexible nylon retroreflective sheet sewn thereon and covered with abrasion resistant water shedding coating. The flexible retroreflective sheet is formed by thermally bonding corner cube, microsphere retroreflectors, or wide angle exposed retroreflective lenses to a flexible polymeric sheet. Due to its low-density foam core construction, the reflective rope floats on water and sheds water from the surface preserving omnidirectional reflectivity. The rope reflects light omnidirectionally over a large angle of acceptance and provides accurate illumination of the rope floating in water, location of a rope wound buoy and the like when used during dusk, fog or nighttime hours.
Abstract:
An eye-and-eye sling in which the protective cover for an endless loop load bearing sling core is not provided with extraneous layers along the body of the sling that extends between the sling eyes. In the inventive sling, first and second loop segments of the load bearing core which are generally diametrically disposed are respectively encased within first and second seamless tubular eye covers. These loop segments and eye covers form the eye portions of the eye-and-eye sling. The spanning portions of the endless loop that are not covered by the eye covers are encased within a common seamless tubular body cover. The body cover and spanning loop segments generally form the body portion of the sling that extends between the sling eyes. The present invention also provides a bridle having an integral master ring and protective covers for the bridal legs in which excessive layers of cover material are avoided.
Abstract:
An endless textile sling for lifting. The sling includes a textile protective cover having a first textile tube, and a second textile tube within the first textile tube to form a double tube structure. The first tube and the second tube are connected together along two respective oppositely positioned longitudinal edges to form an inner sheath and an outer sheath. The sling further includes a load-carrying core within the second textile tube. The core includes a plurality of endless fiber strands. The sling is provided with a plurality of binding elements positioned between the two longitudinal edges and connecting the inner and outer sheaths together. The inner and outer sheaths are separated by a space. The binding elements partition the space into mutually separated chambers. The binding elements include one of a binding warp, a tie-in and an interlaced connection.
Abstract:
Flexible tension member includes a helical bundle of substantially identical elongate elements. Each element inside the bundle is in contact with six adjacent elements, and the lay length of the helical bundle is at least 30 times its diameter. Each element is a strand including wires extending helically around the axis of the strands and substantially all of the strands have a helical lay direction opposite to the helical lay direction of the bundle.
Abstract:
Well tools are run into a well, usually a deviated well, using a composite wireline cable made up of a bundle of parallel slidable composite rods and electrical or optical conductors covered with a flexible protective sheath. The cable is stored on a spool and from there it is run into and retrieved from the well.
Abstract:
A method for fabricating a steel wire cable having a Zn—Al alloy plating, the method including: arranging steel wires according to an arrangement rule at a cross section of the steel wire cable; controlling a length of the overall cable by a length of a central standard wire; twisting a bunch of the steel wires comprising a zinc-aluminum alloy plating with a torsion angle of between 2° and 4°; wrapping the steel wire bunch with a polyester wrapping bandage and covering a resulting product with a double-layered protective polyethylene sheath; anchoring the two ends of the steel wire cable by anchors using fillers; and coiling the finished-product of the steel wire cables.
