Abstract:
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.
Abstract:
Wires are wound and simultaneously laid directly on the core of the product to form a wound layer between the adjacent wires of which there are peripheral spaces constituting from 15 to 70 percent of the wire diameter. The partly finished twisted wire product made in this manner is subjected to compression so as to cause its plastic deformation in order to obtain the desired shape and size. The wires of the wound layer of the finished product have a contact with the core substantially along the surface thereof as a result of compression applied to the product so as to cause its plastic deformation to produce the desired shape and size.A twisted product made by applying this method has uniform mechanical properties over its whole cross section.
