Shandong Lisheng Machinery Co., Ltd. is a new generation enterprise dedicated to the hardware industry. It is located in Jining City, Shandong Province, the hometown of Confucius and Mencius. The company is a professional hardware supporting enterprise integrating design, research and development, production and sales. The main products are chains, wire ropes and their accessories: shackles, turn buckles, clips, rings, snap hooks and other forgings and castings, and accept drawings and samples for processing.
The wire ropes are stressed by fluctuating forces, by wear, by corrosion and in seldom cases by extreme forces. The rope life is finite and the safety is only ensured by inspection for the detection of wire breaks on a reference rope length, of cross-section loss, as well as other failures so that the wire rope can be replaced before a dangerous situation occurs. Installations should be designed to facilitate the inspection of the wire ropes.
Lifting installations for passenger transportation require that a combination of several methods should be used to prevent a car from plunging downwards. Elevators must have redundant bearing ropes and a safety gear. Ropeways and mine hoistings must be permanently supervised by a responsible manager and the rope must be inspected by a magnetic method capable of detecting inner wire breaks.
Wire rope offers numerous benefits in various applications. It provides exceptional strength and durability, allowing for the safe lifting and transportation of heavy loads. Wire rope is resistant to corrosion and abrasion, making it suitable for use in harsh environments. It has a high tensile strength-to-weight ratio, enabling efficient and cost-effective operations. Wire rope also offers flexibility and adaptability, making it suitable for use in a wide range of industries and applications.
Wire rope is available in different types to meet specific application requirements. The most common type is the standard six-strand wire rope, which provides a balance of strength and flexibility. There are also compacted wire ropes that offer increased strength and reduced elongation. Rotation-resistant wire ropes are designed to minimize twisting and spinning during lifting operations. Additionally, specialty wire ropes, such as stainless steel wire rope or plastic-coated wire rope, are used in specific industries or environments that require corrosion resistance or protection.
Wire rope consists of several individual steel wires twisted together to form strands, which are then helically laid around a core. It is composed of high-quality steel wires that are carefully selected for their strength and performance. Wire rope is available in various constructions, including different numbers of strands and wires per strand. It comes in different sizes and diameters to accommodate different load capacities and application requirements. Wire rope can also be galvanized for added protection against corrosion.
I am very satisfied for top quality product,quick response and attention provided by this seller and company，Thank you!
Quikly send,very good communication,all is ok,without problem.
Very good quality,fast and safe shipment,Nothing to improve
Great seller!Always online and helpful.Speedy delivery,very good and secure packing.
<p>Wire ropes are used dynamically for lifting and hoisting in cranes and elevators, and for transmission of mechanical power. Wire rope is also used to transmit force in mechanisms, such as a Bowden cable or the control surfaces of an airplane connected to levers and pedals in the cockpit.</p>
<p>The term cable is often used interchangeably with wire rope. However, in general, wire rope refers to diameters larger than 3/8 inch. Sizes smaller than this are designated as cable or cords. Two or more wires concentrically laid around a center wire is called a strand.</p>
<p>Wire rope, often called cable, is sized by diameter (not circumference, as large sizes of fiber rope are). The diameter is measured across the rope, not from flat to flat. The rope's construction is described by a designation like &ldquo;6 &times; 17&rdquo;. the first number is the number of strands.</p>
<p>he strength of wire rope is broken down into different grades, including: Improved Plow Steel (IPS) Extra Improved Plow Steel (EIPS) is 15% stronger than IPS. Extra Extra Improved Plow Steel (EEIPS) is 10% stronger than EIPS.</p>
