  • Publication number: 20150024891
    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.

  • Patent number: 8181312
    Abstract: An end-connector for fastening a flat-belt type suspension device of an elevator system comprises a housing with two side walls and a first and a second wrapping element each of which extends between the two side walls and is wrappable by the flat-belt type suspension device in a specified arrangement so as to hold the suspension means fast in the end-connector by frictional engagement. Marked on at least one of the two side walls on the outside that faces away from the wrapping elements is the specified arrangement of the suspension device.

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.

  • Patent number: 6464042
    Abstract: A direct drive apparatus for an elevator wherein a movable part of the direct drive, particularly a linear motor, is connected with ark elevator car or counterweight for transmission of compression and tension in the travel direction by a tension/compression strut with settable damping properties. The tension/compression strut includes first and second rods which lie on a longitudinal axis of the strut and extend into opposite ends of a sleeve. First and second nuts are threadably received in the ends of the sleeve. First and second spring elements are positioned in the sleeve abutting the first and second nuts respectively. A central spring element is positioned between first and second spring plates which abut the first and second spring elements respectively. Each rod extends through the respective nut, spring element and spring plate into the central spring element and is attached the respective spring plate to optimize the oscillation and body sound insulation.
