Problems solved by technology

A problem that is often encountered when assembling and disassembling the parts is that, as viewed from the elevator car, the screw connection is positioned at the rear of the column, and access to the screw is usually restricted from the elevator car, in order to access the screw connections, workers are often forced to climb out onto the posts
Due to the very high heights involved, it should be recognized that the assembly and disassembly of said parts is a very dangerous operation when handling these uprights

Embodiment Construction

[0018] Figures 1-4 show an elevator system according to the invention comprising a column 1 constructed from a number of column parts 2 superimposed and mounted on top of each other and an elevator car 3 which is guided along the column in a known manner by guide rollers move on the vertical pipe. The elevator car 3 is also provided, in a known manner, with an electric motor, which meshes with a rack on the column 1 by means of gears. Although the principles described here for the elevator system according to the invention are applicable to a covered cage elevator car 3, it should be recognized that the principles can also be applied to open doors having only guardrails, commonly referred to as working platforms type elevator car. The term elevator car 3, as used in the following, denotes a car of a substantially known prior art type, for people and goods, for elevator systems in which a column 1 is constructed from a number of parts 2 mounted on top of each other and the co...

Abstract

The invention concerns an elevator system comprising an elevator car with a working platform arranged for carrying people or materials and which by means of the interaction between a gear wheel and gear rack can be moved along an elongated generally vertical mast constructed from a number of mast sections mounted on top of each other. To facilitate the erection, tearing down and anchoring of the mast to a nearby building structure, the moving unit comprises a passenger-carrying service and assembly platform, which, via a swing arm, is flexibly supported by the elevator car to allow a swivel action in a horizontal plane (C, D) relative to the elevator car.

Description

technical field [0001] The present invention relates to an elevator system comprising essentially a vertical column constructed from a number of mutually assembled components and a cage or platform elevator car capable of moving along the constructed column to transport people or goods. Background technique [0002] Although an elevator of the aforementioned type can be used as a permanently installed service elevator, its particular use is in the construction or renovation of buildings, where the elevator is constructed for temporary use. A major advantage is that the columns contained in the elevator system can be extended by stacking on top of each other and installing new components, thus being adapted to gradually increase the height of the building. The columns thus constructed can be dismantled in the opposite way using the elevator car by disassembling the components and transporting them off the top of the columns. Where the elevator car is cage-type, the top of th...
