The company maintains high standards of quality through rigorous testing and collaboration with scientific institutions.
Wire ropes are constructed with wires twisted into strands and strands twisted into the rope. The direction of these twists determines the lay type: sZ (right hand regular lay), zZ (right hand langs lay), zS (left hand regular lay), and sS (left hand langs lay). If not specified, sZ is supplied.
Coated wire ropes are recommended for applications involving pulleys or reverse bending. Polyamide is commonly used for its wear and bending resistance, protecting the rope from dirt and maintaining lubrication. PTFE is used for high temperature or low friction requirements.
TechnoCables are made from high tensile strength wires, typically galvanized steel or stainless steel (AISI 316). For corrosive environments, AISI 316 is recommended. Custom materials like titanium, monel, and precious metals are available for specific applications.
The working life of wire ropes depends on factors like pulley diameter, deflection, and dynamic loads. Testing is essential for optimizing and developing products.
Elongation in wire ropes can be constructional, due to gaps between wires and strands, or material-based, proportional to the load applied. Ropes generally return to their original length after unloading unless plastically deformed.
Various constructions are available for different applications, including control cables, suspension systems, and heavy-duty cycles. Applications span automotive, medical, conveyer, and more industries.
Carl Stahl Technocables ensures high quality through continuous quality assurance from raw materials to dispatch, with regular testing in laboratories.
Wire ropes are used in automotive, medical, conveyer, and other industries for applications like safety belt adjustment, gear change, and window lifting systems.
Specifications for stainless steel strands include minimum breaking load, weight, and nominal diameter, with various item numbers for different configurations.
The document provides detailed specifications for various components such as end caps, adjustment screws, hose sockets, and pulleys. Each component is listed with dimensions in millimeters, including diameter, length, and other relevant measurements. The document also includes item numbers for both new and old versions of each component.
The document outlines the importance of selecting the correct pulley and wire rope combination to optimize the lifespan of the wire rope. It provides guidelines on groove geometry, the ratio between groove and rope diameter, surface quality, and material selection.
Recommendations are provided for the minimum diameter of pulleys based on rope construction. The document emphasizes the importance of choosing the right pulley bearing and provides a decision matrix to assist in this selection.
The tables include dynamic load capacities for bearings under normal conditions, with specific calculations for different rotation speeds. The document also provides weight information for components per 100 pieces.
Hose sockets are available in nickel-plated brass, galvanized steel, or stainless steel, with options for neck, thread, and hexagon thread. Pulleys are made from polyamide and feature various bearing types, including self-lubricating sintered bronze and needle roller bearings.
Nylon pulleys are highlighted for their lightweight, corrosion resistance, self-lubrication, and high impact resistance. The document notes the improved tensile strength of lubricated polyamide, allowing for higher loads compared to thermoplastics.

INFOBLOCK I GENERAL INFORMATION Drahtlitzen werden aus einzelnen hochfesten Seildrähten gefertigt, welche spiralförmig um eine Einlage gelegt werden. All strands are manufactured with high tensile wires. The wires are twisted helically to form the strand. The design of wire ropes Drahtseile werden ebenfalls durch spiralförmiges Verseilen von Litzen erzeugt, wobei hier keine Einzeldrähte sondern Litzen verwendet werden. Als Einlage kann neben einer Litze oder Seil auch eine Fasereinlage verwendet werden. Wire ropes are also manufactured by twisting helically, but this time strands are used rather...

INFOBLOCK I GENERAL INFORMATION Die Schlagrichtung gibt die Richtung an, in der bei Litzen (Seilen) die Außendrähte (Außenlitzen) um den Mitteldraht (Einlage) gewickelt werden. The lay describes the direction in which the wires of a strand or the strands of a rope are twisted around a central wire or core. Werden die Außendrähte (Außenlitzen) links um den Mitteldraht (Herzlitze) gelegt, spricht man von einem S-Schlag oder der Schlagrichtung links. In a strand, if the wires are laid heli-cally over a centre wire in a left direction, the lay is called S-lay or left lay. Werden die Außendrähte (Außenlitzen)...

INFOBLOCK I GENERAL INFORMATION Der Einsatz von ummantelten Seilen Applications for coated wire ropes Ein ummanteltes Seil sollte grundsätzlich überall dort eingesetzt werden, wo Seile über Umlenkrollen laufen oder auf Biegewechsel beansprucht werden. Coated wire ropes can be found in most applications where pulleys are used and where the TechnoCable will be subject to reverse bending. Je nach Anwendungsfall muss der geeignete Ummantelungswerkstoff gewählt werden. Aufgrund der hohen Verschleißfestigkeit und Biegewechselfähigkeit wird Polyamid eingesetzt. Durch die Ummantelung wird das Seil vor...

INFOBLOCK I GENERAL INFORMATION Bei TechnoCables unterscheidet man zwei unterschiedliche Arten der Dehnung - die konstruktionsbedingte und die Materialdehnung. Two different kinds of elongation can be distinguished. Constructional elongation of TechnoCables and material elongation which is specific to the material used in the manufacturing process. Konstruktionsbedingte Dehnung Bei der Fertigung der Seile und Litzen entstehen zwischen den Einzeldrähten und den Litzen kleine Lücken. Unter Belastung verdichtet sich der Drahtseilverband, dadurch entsteht eine leichte Dehnung. Die konstruktionsbedingte...
