Embodiment Construction

[0027] exist figure 1 An example embodiment of an elevator installation according to the prior art is shown in . The elevator system 1 comprises: a car 2 , a counterweight 3 , a drive 4 and a belt-shaped carrier 5 . Here, a belt-shaped carrier 5 is fastened in the elevator installation 1 by means of a first carrier fixture 7 and is guided past the counterweight deflection rollers 10 , past the drive pulley of the drive 4 , past the two car deflection rollers 8 and is fastened again in the elevator system 1 by means of the second support mechanism fastening 7 .

[0028] In the present exemplary embodiment, the elevator installation 1 is arranged in a shaft 6 . In an alternative embodiment, not shown, the elevator installation is not arranged in the shaft, but instead is fastened, for example, to the outer wall of the building.

[0029] figure 1 The elevator installation 1 of the example in includes a counterweight 3 . In an alternative embodiment not shown, the elevator in...

Abstract

In an elevator system, a belt-type suspension means is guided over a driving pulley of a drive unit and over two deflection rolls on an elevator car. Between the two deflection rolls, the belt-type suspension means is additionally guided over a tensioning element which applies a force to the belt-type suspension means. The tensioning element is movably arranged such that the belt-type suspension means is displaced by the tensioning element when the tension diminishes and is thereby tensioned again.

Description

technical field [0001] The invention relates to an elevator installation with a tensioning device. Background technique [0002] In elevator installations, steel cables are conventionally used as support means for supporting and / or driving the elevator car. According to a further development of this steel cable, a belt-shaped carrier is also used, which has a tension carrier and a sheath arranged around the tension carrier. Such a belt-like carrier is guided in the elevator system like a conventional steel cable around the drive pulley and deflection rollers. In contrast to the steel cables, the belt-shaped support means are not guided in channels in the deflection rollers or drive wheels, but the belt-like support means lie flat on the deflection rollers or drive wheels. [0003] As a result, the belt-like support means are less well guided laterally on the deflection rollers or drive wheels than conventional steel cables. As a result, it can happen that the belt-like ca...
