Embodiment Construction

[0089] Each figure shows two motors 1 in each case, at the outer ends of which corresponding brakes 2 are arranged or fastened. In the variant of the invention shown, the motor shaft 3 also acts simultaneously as the brake shaft 3 . This means that the brake 2 can brake the motor shaft 3 by means of corresponding brake elements, such as brake shoes, brake pads, or the like. Without being shown in more detail, the brake 2 can be a disc brake, a multi-plate brake or the like, wherein in particular brakes 2 already available on the market can be used.

[0090] The motor 1 has a rotor 4 , a drive shaft 6 driven or braked via a motor shaft 3 and a coupling 5 .

[0091] According to FIG. 1 , a total of four small drive sprockets 7 are fastened to the drive shaft 6 , each of which drives a chain 8 , in particular an inverted tooth chain 8 .

[0092] Without being shown in detail, an elevator car or a load receiving device such as an elevator car or an elevator platform is suspended...

Abstract

The invention relates to a lifting device, especially a lift or a lifting platform, comprising a displacement unit for at least partially displacing a load in a vertical manner. The displacement device comprises at least one first drive motor comprising a first motor shaft and especially a second drive motorcomprising a second drive shaft, in addition to one first brake unit arranged on a first brake shaft and a second brake unit arranged on a second brake shaft , in addition to at least one first drive element which can be rotated about a first drive shaft in order to drive at least one first traction element which is subject to tension and a second drive element which can be rotated about a second drive shaft in order to drive at least one second traction element which is subjected to the effect of tension. The traction element and the load are respectively arranged between at least two drive shafts enabling costs to be reduced and operational safety to be increased in relation to lifting devices of prior art. This is achieved by virtue of the fact that means for the production of a continuous mechanical positive locking are provided, whereby the positive lock comprises at least the first and second brake unit and the first and second drive element.

Description

technical field [0001] The invention relates to a lifting device, in particular an elevator or a lifting platform, according to the preamble of claim 1 . Background technique [0002] Hitherto, various elevators with different drive systems and supporting structures, which are usually designed to be self-supporting between floors of a building, are often used. A load-receiving device or an elevator platform or an elevator car is fastened to the lift trolley, in which case the lift trolley is moved along the travel path by means of a drive unit. Both the lift truck and the load-receiving device are often guided on the support structure. [0003] For example, in single-family or multi-family buildings, office buildings etc., corresponding elevators are often installed in buildings with approximately 2 to 10 floors as the buildings are modernized. However, conventional elevators are relatively expensive, so that they are currently used less particularly as so-called "home ele...
