Abstract:
La présente invention concerne un dispositif de monte-charge (1 ) monté dans une construction (10). De tels dispositifs de monte-charge connus pour déplacer des charges d'un étage de la construction à un autre. Cependant, ces monte-charge sont d'installation limitée et laborieuse de par l'espace dans lequel ils doivent être intégrés. L'invention prévoit pour résoudre ces problèmes un dispositif de monte charge comportant une structure rigide unitaire (9) intégrant un support de levage (4), un système de guidage (5) et un moyen d'entraînement (6) dudit support de levage.
Abstract:
Die vorliegende Erfindung betrifft einen Aufzug mit einer Antriebseinheit. Weiterhin betrifft die vorliegende Erfindung eine Windenergieanlage mit einem Aufzug. Um die Kosten für den Aufzug zu verringern und so den Aufzug wirtschaftlich attraktiver zu machen, ist der Aufzug der eingangs genannten Art gekennzeichnet durch einen als Fahrkorb verwendeten Schrank. Dabei liegt der Erfindung die Erkenntnis zu Grunde, dass sich ein Schrank in seinem grundsätzlichen Aufbau mit Boden, Seitenwänden und einer Tür nicht von einem speziell für einen Aufzug hergestellten Fahrkorb unterscheidet. Natürlich gibt es Unterschiede, z. B. in der Aufhängung und Bedienung der Tür, aber diese Unterschiede können, soweit sie einer Verwendung eines Schrankes als Fahrkorb entgegenstehen, beseitigt werden, sodass der Aufwand insgesamt immer noch geringer ist als der Aufwand für einen eigens für den Aufzug konstruierten Fahrkorb.
Abstract:
The invention concerns a trailer device convertible into an elevator for works high above the ground which consists in using a trailer specially designed to be converted by being tilted in vertical position into a multipurpose construction site elevator with variable and adjustable height.
Abstract:
An elevator system permitting horizontal movement of a normally vertically moving elevator cabin, the elevator cabin being automatically attached to or detached from an elevator frame and horizontally moved to or from another elevator shaft or other destination. While an elevator cabin is supported on an elevator frame or other surface, various cables, rods, plugs and other equipment are automatically connected to or disconnected from the elevator cabin to enable vertical or horizontal motion of the elevator cabin. Once disconnected from such devices, the elevator cabin can be propelled horizontally out of the elevator frame and elevator shaft, onto other surfaces, such as floors of a building, and move horizontally to another destination. An elevator cabin may also be horizontally moved into an elevator shaft and onto the surface of an elevator frame, and connected to the frame, thus enabling such cabin to then move vertically within an elevator shaft.

본 발명은 드릴십, 반잠수식 드릴 리그, 고정식 플랫폼, 부유식 플랫폼 등 다양한 해양 플랜트 구조물에 적용되는 수직 경사형 해상구조물용 방폭형 엘리베이터에 관한 발명이다. 프레임과 트러스가 복잡하게 엮여져 있는 해상구조물에서 경사구간과 수직구간이 복합적으로 이루어진 엘리베이터를 구성한다. 이때, 경사구간에서 엘리베이터의 이동은 랙-피니언 방식으로 수행하며, 수직구간에서 엘리베이터의 이동은 와이어-로프 방식으로 수행하게 된다. 또한, 폭발에 취약한 구성은 일정 두께 이상의 금속재질로 이루어진 방폭챔버 내부에 구비하여 폭발로부터 약한 구성을 보호하는 것을 특징으로 한다.
Abstract:
The invention concerns a method and an arrangement for the power supply for a lift of the type in which drive machinery (109) is supported by a load carrier (107) and can drive the load carrier in a first and a second direction along a track along an essentially vertical mast (110) by means of the interaction between a cogged wheel (111) and cogged rod (112). In order to reduce the requirement for external power and in this way to reduce the costs of the power supply system of the lift as a whole, the method is proposed according to: that a load carrier (107) is arranged, that the load carrier (107) is arranged to support an electrically operated electric motor (109) that is a component of the drive machinery, which electric motor is selected such that it generates a flow of energy during regenerative operation, that the electric motor (109) is arranged such that it can drive the load carrier (107) in the first direction along the track and can drive the load carrier during inverse regenerative operation to generate a flow of energy during braking and motion in the second direction along the track, that the load carrier (107) is arranged to support an energy storage system (10) that includes an energy store (60) designed to store, receive and release electrical energy, that the load carrier (107) is provided with a first current-transfer bus (11) that allows the energy flow that is emitted from the electric motor (109) during braking and regenerative operation to be transferred from the electric motor to the energy store (60) that is part of the energy storage system (10) and, when necessary, to be inversely transferred from the energy store to the drive motor, and that the load carrier (107) is arranged to increase its potential energy during acceleration or motion upwards along the mast through the influence of energy that has been obtained from the energy store (60).
