Abstract: A process for producing a support belt for an elevator system includes steps of: placing at least one cable-shaped tension support in position; embedding the tension support in a first belt layer made from a first plasticizable material to produce a partial belt having a first outer surface and a surface which forms a connecting plane, wherein parts of the tension support project out of the connecting plane and at least parts of the projecting portion of the tension support are covered by the first plasticizable material; and integrally forming a second belt layer made from a second plasticizable material on the connecting surface of the partial belt and the projecting portions of the tension support so as to produce a support belt having the first outer surface on the side of the first belt layer and a second outer surface on the side of the second belt layer.

Abstract: An elevator system includes a car or platform to transport passengers and/or goods as well as 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 a sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material and a second layer with a connection plane formed between the first and second layers. At least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—is embedded in an area of the connection plane, a majority of a surface of said at least one tension member directly contacting said first layer. A manufacturing procedure for one of the suspension elements is provided.

Abstract: An elevator installation has at least one elevator car and at least one counterweight which are displaced in opposing directions along at least one guide track in an elevator shaft by a supporting and driving apparatus that is guided by a drive pulley of a drive. The supporting and driving apparatus is fastened directly to the elevator car eccentrically with respect to a center of gravity of the elevator car so that a tilting or load moment results thereby, wherein the tilting or load moment is compensated by a compensation device.

Abstract: An elevator installation is provided that includes an elevator cage, a drive pulley, at least one support means formed as a flat belt, and a drive engine which drives the at least one support means, which carries the elevator cage, by way of the drive pulley. In the elevator installation, the support means has, at least on a running surface facing the drive pulley, several ribs of wedge-shaped or trapezium-shaped cross-section which extend parallel in a longitudinal direction of the support means and further has several tensile carriers oriented in the longitudinal direction of the support means. The tensile carriers are sized so that a total cross-sectional area of all the tensile carriers amounts to 30%-40% of a cross-sectional area of the support means. The tensile carriers may be distributed in a transverse direction of the support means so that exactly two tensile carriers are associated with each of the ribs, the tensile carriers having an outer diameter equal to 35%-40% of a rib spacing (T).

Abstract: In an elevator element for driving or reversing an elevator suspension device in an elevator system, that interacts with an elevator suspension device, the arithmetic mean of the roughness value of the contact surface measured in the circumferential direction of the elevator element, and the mean roughness value of the contact surface measured in the axial direction of the elevator element, are different. The arithmetic mean roughness value of the contact surface measured in the circumferential direction of the elevator element is less than 1 micrometer.

For the purpose of guiding the flat belt on the belt-sheaves, the belt has at least one guide groove in which at least one guide rib projecting from the sheave running surface of the belt-sheave engages.

Abstract: An elevator system has a suspension member for supporting and/or moving an elevator car and being guided and driven by a traction sheave of a drive unit. The suspension member is a cord or rope that includes a body made of a polymer and at least one tension member made of wires extending in the longitudinal direction of and embedded in the body. A thickest wire in the tension member has a bending stress ?b in a range from 350 N/mm2 to 900 N/mm2 when bending the tension member about a minimum bending radius r, and wherein the bending stress is a function of the elastic modulus E and the diameter ? of the thickest wire, according to the equation ?b=(?*E)/2r, wherein the suspension member is run about a pulley having a minimum diameter D corresponding to no more than two times the minimum bending radius (D?2r).

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.

Abstract: A belt end connection for fastening a support belt end in an elevator installation and a method for protecting and checking a belt end connection in an elevator installation includes a twisting prevention device that prevents twisting of the belt end connection about the longitudinal axis thereof. A wedge retains the support belt end in a wedge pocket and is secured by a loss prevention device against slipping out of the wedge pocket. The twisting prevention device and/or the loss prevention enable efficient protection of the support belt and/or of the belt end connection against damage and make possible efficient checking and control of the belt end connection.
