Abstract:
본 발명은 라운드슬링에 관한 것으로, 특히 정해진 파단 비율에 따라 원사를 연사하여 전도체 코팅을 한 후 심튜브와 함께 압출성형함으로서 전류가 통하면 계속사용하고 전류가 통하지 않으면 정해진 파손 범위를 넘어선 것으로 판단하여서 사용을 방지하도록 하여 안전사고를 예방할 수 있도록 한 라운드슬링 및 그 제조방법에 관한 것이다.
Abstract:
An exemplary method of making a load bearing elevator traction belt includes applying individual coatings of a jacket material to each of a plurality of tension members such that each tension member is individually coated separately from the other tension members. A portion of the individual coatings are joined together to secure the tension members into a desired alignment and to form a single jacket that establishes a geometry of the belt.
Abstract:
Ein Aufzug umfasst eine Kabine (3), eine Gegengewicht (8), ein mit der Kabine und dem Gegengewicht zusammenwirkenden Tragmittel (12) und ein von dem Tragmittel wenigstens teilweise umschlungenen Rad (4.1, 4.2, 4.3, 4.4), wobei das Tragmittel eine Zugträgeranordnung aus zwei Zugträgern (14) und einen die Zugträgeranordnung umhüllenden Mantel (13) aufweist, der in einem Bereich einer Außenoberfläche (13.1), der das Rad (4.1, 4.2, 4.3, 4.4) teilweise umschlingt, eine Längsstruktur aufweist, und wobei das Verhältnis der Breite (B) des Tragmittels zu dessen Höhe (H) größer eins und kleiner oder gleich drei ist (1
Abstract:
An elevator load bearing assembly (20) includes a plurality of cords (22) within a jacket (24). The jacket has a plurality of grooves (32, 34, 36, 38 40) spaced along the length of the belt assembly. Each groove has a plurality of portions (50, 52, 54, 56) aligned at an oblique angle (A, B) relative to a longitudinal axis (48) of the belt (20). In one example, the grooves are separated such that there is no longitudinal overlap between adjacent grooves. In another example, transitions (60, 64) between the obliquely aligned portions are at different longitudinal positions on the belt. Another example includes a combination of the different longitudinal positions and the non-overlapping groove placement.
Abstract:
The invention comprises a lift belt (10) having a ribbed profile (25) on a pulley engaging surface. The lift belt also comprises steel tensile cords (15) within an elastomeric body. The ribbed profile engages a ribbed profile on a pulley. The lift belt exhibits increased load lifting capacity due to the increased surface area of the ribs as compared to a flat belt. The belt (10) also comprises conductive tensile cords having a resistance (Br). A change in resistance is used for measuring a belt condition as well as a belt load.
Abstract:
A hoist for an elevator, wherein a rotating shaft (6) supported rotatably on bearing stands (2, 3) is rotated by a driving force of a drive motor (8) so as to move a car up and down through a main cable (7), a main cable application part (6a) for applying the main cable (7) thereto is formed integrally with the rotating shaft (6) and a plurality of rope grooves (6b) for inserting the main rope (7) therein are provided in the main rope application part (6a).
Abstract:
A hybrid material tension member (22) for an elevator or other people transportation system (12) using organic fiber (30) and steel material (28) as the load carrying components either discretely or in combined form. Several embodiments are disclosed.
Abstract:
An elevator system having multiple machines and flat ropes is disclosed. In one embodiment, the machines are engaged in a series manner with a single set of ropes to drive the car and counterweight. In another embodiment, each machine is engaged with a separate set of ropes to drive the car and counterweight.
Abstract:
Elevator rope arrangement in which the elevator car (1) and counterweight (2), travelling along guide rails in an elevator shaft, are supported by suspension ropes (3), which are attached to the top part of the elevator car (1) and passed via at least one diverting pulley (4) to the counterweight (2). Separate hoisting ropes (5) are attached either to the upper or lower part of the counterweight (2) or to the upper or lower part of the elevator car (1) and so guided that, between their points of attachement, they run via the treaction sheave (7) of the drive machine (6) and at least one diverting pulley (8). The hoisting rope (5) is a substantially thin rope made of synthetic fibre and having a sheath of plastic material.
Abstract:
Seil (10) zur Abspannung des Turms einer Windenergieanlage mit einem Kern (K) von unidirektional angeordneten Rovings (R), die jeweils aus einer Mehrzahl von Filamenten gebildet und mittels eines Matrixwerkstoffs (M) miteinander verbunden sind, und einem in Längsrichtung des Seils (10) verlaufenden Blitzschutzelement (B), das den Kern (K) entlang dessen Umfang jedenfalls teilweise umgibt.
