10-20M Fall Arrest Wire Retractable Safety Lifeline with EN 360 Standard

Fall arresters production - details determine quality

 It is a light and small security tool, which can carry out lifting, descending, traction, calibration and other operation operations. It can conveniently select security position. Its advantages of simple and compact structure, light weight, small size, easy to carry, safe and reliable, and long service life have gradually become the first choice for field operations in high altitude operation industry. Tools.            

 It is well known that the working conditions in the field are difficult, especially at high altitude. Not only is the living facilities incomplete, but also the hidden danger of operation safety increases greatly because of the bad environment objectively in the field. Therefore, in the field lifting operation, the quality requirements for the use of tools of the high-altitude fall arresters are also increased. As the preferred tool for field lifting, the quality of fall arresters is the focus of attention.            

 Fall arrester's anti-collision rubber pad, anti-skid head, wear resistance, reduce the damage to the shell caused by quick rebound at the lock; new type self-locking hook design of speed difference fall arresters can further enhance your safety; in addition, the safety rope of fall arresters adopts aviation grade steel wire rope, which is safe and durable, and is not easy to rust; the contact position between hook and suspension rope is installed. The utility model has a rigid industrial plastic protective sleeve, whose function is to reduce the contact between the hook and the fiber suspension rope, thereby reducing the wear and tear, and improving the service life of the suspension rope.            

 The high-quality aluminium alloy shell of the safety fall arresters effectively protects the internal structure and the sealing process is rigorous. It prevents the infiltration of rainwater and oil, affects the internal structure performance, and improves the use performance and efficiency of the fall arresters.            

 How can a high-quality fall arresters withstand tens of times the impact of instantaneous acceleration? It was originally made of high-quality manganese steel forged by the internal ratchet wheel of the fall arresters, which has excellent impact resistance.            

 Wear-resistant alloy steel is a kind of special performance steel used  in wear conditions. Its main characteristics are high strength, hardness, toughness and wear resistance under wear conditions. Strictly speaking, wear-resistant manganese steel also belongs to wear-resistant alloy steel. Considering that wear-resistant manganese steel is often classified as one class in the wear-resistant material industry at home and abroad, the main purpose of wear-resistant manganese steel adding alloy elements is to improve hardenability, strength, toughness and wear resistance. The most commonly used additives are Mo, Cr, Mn, Ni, Si and so on.            

 The casting and welding properties of wear-resistant low-alloy steel are similar to those of other low-alloy steels, but the welding performance is poor when the carbon content is high. Low alloy wear resistant steel can be classified according to heat treatment and carbon content.           
 1.  Water quenching heat treatment alloy martensitic wear resistant steel            

 2.  Oil-quenched and air-quenched heat-treated low-alloy martensitic wear-resistant steel           

 3. Normalized heat-treated low-alloy pearlitic wear-resistant steel            

 4.  Wear-resistant carbon steel cast graphite steel is ultra-high carbon eutectoid steel           

 The most important feature of high manganese steel is that under strong impact and extrusion conditions, the surface hardening occurs rapidly, which keeps good toughness and plasticity of austenite in the core, while the hardened layer has good wear resistance.This is beyond other materials. However, the wear resistance of high manganese steel shows its superiority only when it has enough conditions to form work hardening, but in other cases it is very poor. Therefore, the inner gear of the crash preventer made of high-strength alloy steel has the advantages of high-manganese steel to ensure that the differential crash preventer has enough impact resistance in the instantaneous fall, and to ensure the safety of the operator.
