摘要:
An elevator installation includes an elevator car, a drive and a belt arrangement with at least one belt, wherein the belt has a belt body in which a tensile carrier arrangement is arranged and which has a first contact surface on a first cross-sectional side in the direction of the height of the belt and a second contact surface on a second cross-sectional side opposite the first cross-sectional side in the direction of the height of the belt. The ratio of the maximum width to the maximum height of the belt is in a range of 0.8 to 1.0, preferably in the range of 0.9 to 1.0 and particularly at 1.0.

A lift installation according to the invention comprises a drive unit (2) which by way of a drive wheel (4.1) drives at least one lift support means (12) supporting a lift cage (3), wherein the lift support means has on a traction side facing the drive wheel (4.1) a rib arrangement with at least two ribs (13) which extend in longitudinal direction of the lift support means and which engage in corresponding grooves on the drive wheel, wherein the rib arrangement comprises a tensile carrier arrangement with at least one tensile carrier (14) arranged in a rib. The lift support means has on a belt back side remote from the traction side a carrier band (15) to which the ribs of the rib arrangement are fastened. A groove (16) reaching substantially as far as the carrier band is formed between two adjacent ribs (13) of the rib arrangement.

A transmission belt for driving and/or supporting an elevator car has a longitudinally extending body including an area tensile layer reinforced by chemical fibers. The belt can have a flat friction layer or a friction layer including alternating longitudinally extending wedge-shaped ribs and grooves. Transverse grooves can be formed across the width of the longitudinally grooved friction layer.

In a support means system a belt-like support means (12.3), which supports a load and which has at least one rib (20.3) or groove with wedge-shaped cross-section extending in the longitudinal direction of the support means (12.3), is driven by a support means pulley (4.3), which has at least one corresponding groove or rib (22.3) with wedge-shaped cross-section extending in circumferential direction, wherein a cavity (34, 35) is present between a rib crest of the wedge-shaped ribs (20.3, 22.3) and a corresponding groove base when the support means (12.3) rests on the support means pulley (4.3).

The invention relates to a lift system wherein a drive unit (2) drives, by means of a driving disk (4.1), a flat belt-type carrier means (12.1, 12.2) which carries the lift cage (3). Said flat belt-type carrier means comprises several ribs (20.1, 20.2) which extend in a parallel manner in a longitudinal direction of the carrier means on a bearing surface which is orientated towards the driving disk (4.1) and each rib comprises at least two traction carriers (22) which are orientated in a longitudinal direction of the carrier means. The whole cross-sectional surface of all the traction carriers (22) is at least 25% of the cross-section surface of the carrier means.

In an elevator installation, an apparatus and a method use a support end connection for fastening a support device to an elevator car, a counterweight and/or a building. The support device has at least one cable or cable strand enclosed by a cable casing and is held in a wedge pocket by a wedge. The cable casing is formed of thermoplastic material or an elastomer and at least one of a region of the wedge or the wedge pocket is provided with a longitudinal wedge groove and a region of the wedge, of the wedge pocket or the cable casing has a reduced coefficient of friction. The support device is preferably a multiple cable.

A trailing rope tensioning device for an elevator installation engages a trailing rope that extends from a first hitch point of a car frame to a second hitch point of a counterweight frame. The tensioning device has two tensioning pulleys that are arranged offset relative to a vertical direction of travel of the elevator and a transverse horizontal direction. This arrangement of the tensioning pulleys makes it possible to use relatively large tensioning pulleys resulting in a lower number of revolutions per unit of distance traveled, which brings about a reduction in noise from the bearings rotatably mounting the pulleys. Larger diameters of trailing rope and, as a result, fewer trailing ropes can be used. Furthermore, the tensioning pulleys can be standardized.

摘要:
An elevator system with a car or platform to transport passengers and/or goods as well as with a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material, containing a first exterior surface, and with at least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—that is embedded in the first layer of the suspension element. A manufacturing procedure for one of the suspension elements is provided.
