Abstract:
The present invention relates to a polyester fiber having high tenacity and high elongation, which is used for a rope for anchorage, mooring, towage, etc. of a ship. More specifically, the present invention relates to a polyester fiber having the elongation of 6.8% or more at 50% of the maximum load (MBL) measured at room temperature, and a polyester fiber rope comprising the same. The polyester fiber of the present invention can secure excellent shape stability, mechanical properties and abrasion resistance as well as high tenacity and elongation. Thereby, it can be used to prepare the fiber rope which may minimize the yarn breaking even under the changes of external environments such as wild marine, severe ship rolling, etc., remarkably improve the shock absorption performance, maintain the performance as a rope after exposure to the long-term deformation, and thus secure the sufficient safety along with the excellent life time of rope.
Abstract:
A wireline cable (1) comprises inner (10) and outer (20) armour layers formed from wires or strips of armour material wound onto a core (3), with at least one roving (15, 25) disposed between the armour layers (10, 20). The roving (15, 25) typically comprises a bundle of continuous fibres arranged parallel to the strips of armour material, and radially spaced between the armour layers (10, 20). Typically the roving nests in a valley between peaks in each armour layer (10, 20). Typically the roving (15, 25) behaves similarly to the armour layers (10, 20) in respect of elasticity, and heat and pressure resistance.
Abstract:
The invention relates to a method of coupling first and second ropes together, such as to form a mooring line. In one embodiment, a method of coupling a first rope (100) having a core (112) comprising a plurality of multi-strand subropes (1 14) to a second rope (200) having a core comprising a plurality of multi-strand subropes is disclosed. The method comprises the step of forming an eye end termination (116) on the first rope (100) by coupling at least one pair of subropes (114) in the first rope core (112) together to thereby form at least part of a first loop (150, 152) of the eye end termination; and coupling at least one further pair of subropes (114) in the first rope core (112) together to thereby form at least part of a further loop (150, 152) of the eye end termination, said further loop being separate from the first loop. The method also comprises forming an eye end termination (216) on the second rope (200) by coupling at least one pair of subropes in the second rope core together to thereby form at least part of a first loop (250, 252) of the eye end termination; and coupling at least one further pair of subropes in the second rope core together to thereby form at least part of a further loop (250, 252) of the eye end termination, said further loop being separate from the first loop. The loops of the eye end termination of the first rope and the loops of the eye end termination of the second rope are then mounted on a connecting spool (58) to couple the ropes together.
Abstract:
The invention is related to an elevator comprising an elevator car (1) and a suspension roping (R) suspending the elevator car (1), the suspension roping (R) comprising at least one suspension rope (2, 2', 2") connected to the elevator car (1), wherein each of said at least one rope (2, 2', 2") comprises one or more load bearing members (3, 3', 3") embedded in an elastomeric coating (4) forming the outer surface of the rope (2, 2', 2"), and a rotatable traction member (6) engaging the outer surface of said at least one rope (2,2',2").The elevator further comprises means (M, 10) for rotating the rotatable traction member (6). The elastomeric coating (4) is made of microcellular elastomer whereby the rope (2, 2', 2") can receive excessive substance, such as water, and transport it away from the contact between the rope (2, 2', 2") and the rotatable traction member (6).
Abstract:
A push-pull steel cable (10) comprises a core (12) and an outer layer of filaments (16) twisted around the core (12). The cable (10) is provided with an external coating (20) of polyethylene terephthalate. The coating (20) gives to the cable (10) a good resistance against corrosion, a good weatherability, a good adhesion and adhesion retention and a friction resistance which is comparable to the friction resistance of a cable with a nylon coating. The cable (10) can be used as a brake cable, a shifting lever cable or a window elevator cable.

Abstract:
A method of coupling first (100) and second (200) ropes together, such as to form a mooring line is disclosed. Moreover a method of forming eyes (16) as a rope termination is disclosed. According to the first aspect the method comprises the step of forming an eye end termination (116) on the first rope (100) by coupling at least one pair of subropes (114) in the first rope core (112) together to thereby form at least part of a first loop (150, 152) of the eye end termination; and coupling at least one further pair of subropes (114) in the first rope core (112) together to thereby form at least part of a further loop (150, 152) of the eye end termination, said further loop being separate from the first loop. The loops of the eye end termination of the first rope and the loops of the eye end termination of the second rope are then mounted on a connecting spool (58) to couple the ropes together. According to the second aspect, the method also comprises forming at least two eyes as an end termination, wherein each eye is formed by splicing a multi-strand coupling rope (18) to a pair of subropes (14a, 14b). A corresponding mooring line and a rope are also disclosed.
