Abstract:
An assembly and method for using a flexible tensile member as part of the rigging for a dragline bucket. The tensile member includes a stranded core surrounded by a separate armor layer. The armor layer assumes the form of a hollow cylinder having a substantial wall thickness. A significant gap is provided between the outward-facing surface of the stranded core and the inward-facing surface of the armor layer. This gap minimizes wear between the two elements during the normal bending and flexing of the tensile member. A first anchor is attached to a first end of the stranded core and a second anchor is attached to a second end of the stranded core. These anchors serve to transmit tension carried by the stranded core. A first end of the armor layer is also attached to the first anchor and a second end of the armor layer is attached to the second anchor.
Abstract:
A composite cable or rope is described. The cable or rope has an inner metallic rope or core, consisting of a plurality of metal strands, and a plurality of covering layers formed around the inner metallic core. An innovative anchoring and safety system is also described. The system has one or more anchorages, fixed to the roof, in each of which the rope is stably locked by screwing, so as not to create instability problems for people attached to the rope.
Abstract:
In some embodiments, the present invention includes ribbed woven materials, methods for increasing the abrasion resistance of a material, methods for providing an indication of wear, ropes configured to provide one or more alerts as a total breaking weight of a rope is approached, woven rope cover systems for rope-like materials, woven rope structures having ribs, and nonwoven ropes comprising strands including nonwoven strands of material that are configured in a rope construction and further comprising one or more woven rope cords displaced within the nonwoven rope construction.
Abstract:
The instant invention is a rope. This rope includes a blend of filaments including a first filament, and a second filament. The second filament is fluorocarbon polymer filament.
Abstract:
A coated rubber cord comprising a core member coated with a woven cover material in the texture of which a single or a plurality of rubber strings are mixedly woven.
Abstract:
A rope for trawl nets having a high-strength eye-splice comprises an eye portion made of an HMPE material and tied round the end of the rope; a first fixing member preventing the eye portion from unraveling; an HMPE splice portion formed in a splice manner and having an outside and an inside that comprise HMPE, respectively; an HMPE sheathed strand portion in which a basic rope is interpolated inside, and strands of an HMPE material are woven in a blade manner on the outside of the basic rope; a second fixing member located at the end of the HMPE sheathed strand portion and capable of fixing the HMPE sheathed strand portion so that it does not come loose; and a basic rope portion comprising a general PE material.
