Abstract:
A method for manufacturing a hoisting rope (R,R',R",R'") is disclosed, comprising the steps of providing a plurality of elongated composite members (1,1',1",1"'), which composite members (1,1',1",1 "') are made of composite material comprising reinforcing fibers (f) in polymer matrix (m); and arranging the composite members (1,1',1",1"') to form an elongated row (r,r',r",r"') of parallel composite members 1,1',1",1"' , which row (r,r',r",r"') has a longitudingal direction (L), a thickness direction (T) and a width direction (W), and in which row (r,r',r",r"') the composite members (1,1',1",1 "') are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction (W) of the row (r,r',r",r"'); and directing plasma treatment on the outer surface of the composite members (1,1',1",1"'); and embedding the composite members (1,1',1",1'") in fluid polymer material (2); and solidifying the polymer material wherein the composite members (1,1',1 ",1 "') are embedded. The invention relates also to a hoisting rope onbtained with the method and an elevator comprising the hoisting rope. An elevator load bearing belt obtained by said method is also disclosed.
Abstract:
Disclosed is a high traction synthetic rope comprising a braided sheath adhered to a strength member by means of a first synthetic portion and portions of material adhered to the outside surface of the braided sheath by means of a second synthetic portion, where the portions of material are formed of a substance that differs from a substance mainly forming the second synthetic portion and also preferably exhibits greater friction when wet and measured on an iron surface than does the substance mainly forming the second synthetic portion.
Abstract:
An exemplary method of making a woven fabric includes weaving a plurality of load supporting tension members and a plurality of cross fibers together into a woven fabric. A spacing between adjacent ones of the tension members has a first dimension. At least some of the cross fibers are shrunk to thereby decrease the spacing between the adjacent ones of the tension members to a second, smaller dimension. In another example, two woven fabrics are positioned next to each other. The two fabrics include a spacing between adjacent tension members having a first dimension. At least one tension member of one woven fabric is aligned with and between two of the tension members of the other fabric to thereby decrease the spacing to a second, smaller dimension.
Abstract:
Tragelementsystem, insbesondere für Aufzüge, mit mindestens einem Tragelement (1), welches zwei horizontal nebeneinander angeordnete lasttragende Zugträger (11) aufweist, die in einer gemeinsamen, die beiden Zugträger separierenden elastomeren Umhüllung (12) eingeschlossen sind, wobei die Zugträger jeweils eine entgegen gesetzte Schlagrichtung (z, s) aufweisen und mit einer Treibscheibe (2) zur Übertragung einer Antriebskraft auf das mindestens eine Tragelement, wobei die Treibscheibe eine konturierte Traktionsfläche (4) mit zwei für die Übertragung der Antriebskraft vorgesehenen, mit dem Tragelement (1) zusammenwirkenden Auflageflächen (5, 6) aufweist.
Abstract:
Ein Seil umfasst Kohlenstoff enthaltende Filamente, welche jeweils von einer Schlichte ummantelt sind, wobei die von der Schlichte ummantelten Filamente von einer Matrix umgeben sind, wobei die Matrix aus einem wenigstens ein Elastomer und/oder wenigstens ein thermoplastisches Elastomer enthaltendem Material zusammengesetzt ist. Dieses Seil kann insbesondere zum Ziehen einer Last, beispielsweise in einem Lastaufzug, verwendet werden.
Abstract:
L'invention propose un câble de structure (1) comprenant des armatures métalliques tendues (4) noyées dans un produit de protection contre la corrosion (5). Le produit de protection contre la corrosion comprend au moins un inhibiteur de corrosion ayant une tension de vapeur basse.
Abstract:
A new form of construction for synthetic cables used for the anchoring of floating platforms in offshore oil production is described. A desirable requisite for this application is that the durability of the cable is not affected by deterioration of its strong core by virtue of the aggressive mechanical action of particles of the sea bed which might penetrate the cable and reach its core. For this purpose a layer (3) to protect the core (1) comprising a strip of polymer material placed in helical fashion which permits the passage of water and prevents the passage of particles of the sea bed towards the core (1) is placed between the cable core (1) and its outer braided protective layer (2).

A method for manufacturing a hoisting rope (R,R',R",R"'), comprising the steps of providing a plurality of elongated composite members (1,1',1",1"'), which composite members (1,1',1",1"') are made of composite material comprising reinforcing fibers (f) in polymer matrix (m); arranging the composite members (1,1',1",1"') to form an elongated row (r,r',r",r"') of parallel composite members 1,1',1",1"', which row (r,r',r",r"') has a longitudinal direction (L), a thickness direction (T) and a width direction (W), and in which row (r,r',r",r"') the composite members (1,1',1",1"') are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction (W) of the row (r,r',r",r"'); directing plasma treatment on the outer surface of the composite members (1,1',1",1"'); embedding the composite members (1,1',1",1"') in fluid polymer material (2); and solidifying the polymer material wherein the composite members (1,1',1",1"') are embedded. A hoisting rope (R,R',R",R"') obtained with the method and an elevator comprising the hoisting rope (R,R',R",R"') are disclosed, too. The plasma treatment allows for an increased transmission ability of a hoisting rope compared to no plasma treatment.
