9×19S+IWRC - 11 elevator steel rope
9×19S+IWRC
I. Structural Composition
1. 9×19S: This wire rope is composed of 9 strands, with each strand containing 19 wires, and the structure is of the Seale type (S). In the Seale structure, the outer wires have a relatively larger diameter, while the inner wires have a smaller diameter. This unique arrangement endows the wire rope with good wear resistance and fatigue resistance.
2. IWRC: It indicates that the rope core is an Independent Wire Rope Core (IWRC). It is composed of multiple steel wires combined according to a specific stranding process, providing a solid internal support for the entire wire rope.
II. Performance Characteristics
1. High Strength: The structure of 9 strands and 19 wires, combined with the independent wire rope core, gives this wire rope a high breaking tensile force. It can withstand large working loads and is suitable for harsh working environments with strict strength requirements.
2. Excellent Wear Resistance: Due to the thicker outer wires, during the contact and friction with components such as pulleys and drums, the wire rope can effectively resist wear, prolong its service life, and reduce the usage cost.
3. Strong Anti-extrusion Ability: The independent wire rope core endows the wire rope with good anti-extrusion ability. Even under relatively large radial pressure, it can still maintain the integrity of its structure and the stability of its performance.
4. Good Flexibility: Although this wire rope has high strength, through reasonable structural design and process control, it still has a certain degree of flexibility, making it convenient for winding and operation on various equipment.
5. High-temperature Resistance: In some high-temperature working environments, the characteristics of the independent wire rope core enable the wire rope to maintain good performance, and it is not easy to cause a decrease in strength or structural damage due to temperature changes.
III. Application Areas
1. Lifting Equipment: It is widely used in various lifting equipment such as cranes, tower cranes, and electric hoists. As a wire rope for lifting, luffing, traction, etc., it undertakes the crucial task of lifting heavy objects.
2. Elevator Systems: It can be used as the traction rope of elevators. With its high strength and stability, it ensures the safe and smooth operation of elevators, providing a reliable guarantee for the vertical transportation of passengers and goods.
3. Mining Industry: In the hoisting equipment of mines, such as mine hoists, it is used for hoisting ores, equipment, and personnel, etc., and can adapt to the harsh working environment and frequent heavy-duty operations in mines.
4. Ports and Terminals: In the loading and unloading equipment of ports, such as portal cranes and quay cranes, as well as in the mooring systems of terminals, this wire rope can be used for various lifting and mooring operations to meet the needs of efficient port operations.
5. Construction Sites: During the construction process, it is used for the vertical transportation of materials, the temporary fixing of building structures, etc., providing the necessary support for the smooth progress of construction projects.
