Abstract: A wire rope is provided which has an independent wire rope core (IWRC) covered by a plastic jacket. Outer strands are laid on this plastic jacket and wormings or spacers extend from the plastic jacket in between the outer strands to form gaps between the outer strands. Another jacket is provided over the outer strands which also fills the gaps between the outer strands. Both the IWRC and the outer strands are preferably lubricated. A method is also disclosed for manufacturing such wire rope.

Abstract: A wire rope which has an independent wire rope core (IWRC) and outer strands laid around the core. This wire rope has an improved fatigue life when the outer wires of the core and of the outer strands are galvanized. The wire rope may be either fully or partially impregnated with plastic, if desired.

Abstract: A low stretch elevator rope (10) is obtained in which a plastic core (12) has a central strength member (18) that does not increase the weight of the rope by more than 5%. Moreover, the plastic core (12) has a diameter exceeding 50% of the diameter of the rope (10), when measured prior to winding steel strands (14) onto the core (12). The steel strands (14) that are wound around the core (12) are conventional and are so wound that the plastic material of the core (12) essentially fills the inner interstices (16) between the steel strands (14).

Abstract: A wire rope is disclosed, which has at most 18 outer strands and an independent wire rope core, with the strands of the core being laid in the opposite direction to the outer strands of the rope, and a nylon jacket is provided between the core and the outer strands of the wire rope.

Abstract: A cable hook comprises a body member having a longitudinal channel of generally rectangular cross-section formed therein for receiving a portion of a cable against one wall thereof, a cable clamping member laterally movable in such channel and having an inner surface engaging the cable and a longitudinally double-tapered inverted V-shaped outer surface, a transverse aperture extending through the channel, and a wedge member insertable in such transverse aperture and having a vertically tapered surface for driving the cable clamping member against the cable in the channel and a transversally double-tapered surface mating the longitudinally double-tapered surface of the cable clamping member to provide oppositely acting wedging surfaces generating increased clamping action during pulling of the cable in either direction.

Abstract: A cable hook for securing a cable comprises an elongated body member having a longitudinal aperture generally rectangular in cross-section formed therein and provided on one sidewall with two oppositely tapered surfaces, a cable receiving slot formed between an outer surface of the body member and the aperture for laterally inserting a portion of a cable into the aperture against one wall opposed to the tapered sidewall, a second aperture extending through the body member at approximately right angle to the first aperture, first and second wedge members located in the longitudinal aperture and each provided with an inner surface adapted to engage the cable and an outer tapered surface matching one of the tapered surfaces in the longitudinal aperture and adapted to slide thereon, and a third wedge member insertable in the second aperture and having tapered surfaces for driving the first and second wedge members in opposite direction along their associated tapered surfaces for clamping the portion of the cable

Abstract: A strand tensioning tool comprises a tool body, a stationary clamp mounted on the tool body for holding one end of the strand and including a fixed plate secured to the tool body and a gripper plate pivotally mounted on the tool body using two parallel levers for allowing even distribution of clamping stress over a predetermined length of strand, a rotary drum also mounted on the tool body and having a notch across the face thereof for inserting the other end of the strand to tension the strand around packages to be strapped by rotation of the drum, and a guide plate rotatably mounted on the tool body and adapted to trap the strand in the notched drum to prevent it from sliding out of the drum during rotation of the drum.

Abstract: A method is provided for making a plastic-filled wire rope by preheating a lubricated wire rope to a temperature close to the melting point of the plastic material with which the rope is to be filled, and then injecting the plastic material in molten state under heat and pressure into the wire rope so as to fill essentially completely the interstices between the strands and the individual wires, while displacing and removing most of the lubricant initially present within the rope. The obtained novel plastic-filled, lubricated wire rope has improved wear and fatigue resistance as well as increased life.

Abstract: A mechanical splice for forming turn-back loop ends in wire strands is disclosed. This splice comprises an elongated element of extruded aluminum having two longitudinal bores parallel to the axis of the element and separated by a partition of a predetermined thickness. Each bore is of a diameter slightly larger than the diameter of the strand for insertion of the live end of the strand in one of the bores and of the dead end of the strand in the other bore.
