Abstract:
A method of manufacturing an elevator includes installing a movable supporting platform and an elevator car in the elevator hoistway; taking the elevator car into use to serve passengers and/or to transport goods; removing the elevator car from use; changing the service range of the elevator car to reach higher up in the elevator hoistway by lifting the supporting platform higher up in the elevator hoistway; and taking the elevator car back into use. The elevator is reeved to include construction-time hoisting roping, which includes one or more ropes, the longitudinal power transmission capacity of which is based at least essentially on non-metallic fibers in the longitudinal direction of the rope. In the method, guide rails to be fixed with guide rail brackets can additionally be installed by the aid of an installation device. An elevator arrangement can be used to perform the method.

The present invention relates to synthetic cables comprising a core formed of high modulus threads arranged in parallel to each other, wherein the ends of the cable comprise splice-type termination ends (1), wherein each splice (1) comprises high modulus threads arranged in parallel to each other forming an eyelet (11) on each splice, wherein each leg of the threads (13, 13) comprising each splice is connected to a thread (21) that forms the core of the cable, wherein the splice threads (13, 13) and the core threads are arranged in parallel to each other at an interpenetration region (12).The present invention further discloses a method for manufacturing a synthetic cable comprising a core formed of high modulus threads arranged in parallel to each other, wherein the ends of the cable comprise splice-type termination ends (1), wherein each splice (1) comprises high modulus threads arranged in parallel to each other, which method comprises the steps of: individually connecting each leg of the threads (13) comprising a positive splice to a thread (21) of the beginning end of the cable core (2) forming a loop; joining the threads of the positive splice (13) so as to form a loop, straining all the threads, wherein the splice threads (13) and the core threads (21) are arranged in parallel to each other at an interpenetration region (12); applying a normal compression force at the interpenetration region (12) of the positive splice (1); applying at least one protective element (32) along the entire length of the cable; individually connecting each leg of the threads (21) that form a negative splice to a thread (21) of the final end of the cable core (2) forming a loop; joining the threads (13) of the positive splice so as to form a loop, straining all the threads, wherein threads (31) from the splice and threads (21) from the core are arranged in parallel to each other at an interpenetration region (12); and applying a normal compression force at the interpenetration region (12) of the negative splice.
Abstract:
A steel cord (20) comprises a plurality of steel filaments (22, 24) arranged in parallel to the longitudinal axis of the steel cord (20) without twisting. The steel cord (20) further comprises a wrapping filament (26) twisted around the steel cord (20). Each of said steel filaments (22, 24) is a flat wire having flat surfaces. The steel filament (24) near the center of the steel cord (20) has a bigger width than the steel filaments (22) further away from the center of the steel cord (20) such that the cross-section of said steel cord (20) approximates an oval shape with the bending stiffness around the shorter axis of the oval shape being greater than the bending stiffness around the longer axis. In a tire, the steel cord being used as a reinforcement, the longer axis being arranged perpendicular to the radial direction of the tire.

Elevator, preferably a passenger elevator, which comprises an elevator car, and at least one hoisting rope for moving and supporting the elevator car, a traction sheave that acts on the hoisting rope, and a power source for rotating the traction sheave. The counterweight of the elevator comprises a brake for decelerating and/or preventing at least upward movement of the counterweight.
Abstract:
A hoisting device rope has a width larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material, said composite material comprising non-metallic reinforcing fibers, which include carbon fiber or glass fiber, in a polymer matrix. An elevator includes a drive sheave, an elevator car and a rope system for moving the elevator car by means of the drive sheave. The rope system includes at least one rope that has a width that is larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material. The composite material includes reinforcing fibers in a polymer matrix.
Abstract:
A rubber-steel cord composite is provided having nonlinear physical properties even in a rubber characterized by incompressive properties after vulcanization, and hence the rubber-steel cord composite can show low rigidity and flexible properties in a low-strain region and, on the other hand, can show high rigidity in a high-strain region. The rubber-steel cord composite is provided by bundling steel linear objects 1 subjected to spiral shape forming at substantially identical pitches in an approximately identical phase without twisting, the steel cord being embedded in rubber.
Abstract:
A tire cord having core filaments preformed into a helical configuration while maintaining the core filaments in a parallel, side-by-side relationship. The core filaments are not twisted or stranded together. High tensile strength sheath filaments are also preformed into a flattened helical configuration so that the sheath filaments can be wrapped around the side-by-side core filaments such that the sheath filaments do not put such tension on the core filaments as to cause the core filaments to bunch. The core filaments are maintained in a flat, side-by-side configation so that no voids are formed and rubber can penetrate into the tire cord. The core filaments may number from three to six and the sheath filaments from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound, the oval outer bound being characterized by a major axis and a minor axis. It is desirable that the minor axis be no greater than 60% of the major axis to created the appropriate difference in the bending modulus of the tire cord in the horizontal versus the vertical direction.

A reinforcement for a building works structure comprising an assembly of solid wires. The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath made of plastic material enclosing the bundle and providing it with cohesion.
Abstract:
A rubber-covered belt ply forms a belt layer. At least a majority of metal wires in the ply exist as metal wire bundles in which a plurality of metal wires of circular cross-sections and substantially equal wire diameters are aligned in parallel without being twisted together, the metal wire bundles being aligned planarly and in parallel with intervals between the metal wire bundles in a transverse direction. At least one layer, which is a cap layer in which organic fibers are covered with rubber and/or a reinforcing layer which is formed of rubber or whose main component is rubber, is disposed between the belt layer and a tread.
