China Steel Swivel Hook Wire Cable 20M Retractable Lifeline Fall Arresters

Application Technology Means of Fall arresters Internal and External
 The internal gears of the speed differential crash preventer are all treated by special means - carburizing of alloy steel.           
 Carburizing refers to the chemical heat treatment process in which steel parts are heated and insulated in a carburizing medium to infiltrate carbon atoms into the surface layer in order to increase the carbon content and form a certain carbon concentration gradient. After carburizing and quenching, compressive internal stress is generated on the surface of workpiece, which is beneficial to improving the fatigue strength of workpiece.Therefore, carburizing is widely used to improve the strength, impact toughness and wear resistance of parts, so as to prolong the service life of parts. Fall arresters gears are more wear-resistant, corrosion-resistant and have longer service life.           
 What is the reason for the paint on the shell of the fall arresters?           
 The fall arresters shell is painted not only for beauty, but also for rust prevention. In addition, it can also play the role of fall arresters here to remind people to pay attention to, convenient and intuitive identification.           
 RAMHOIST fall arrester is colored with fire-proof and anti-static paint. This kind of coat paint can effectively prevent the occurrence of static electricity, so it can effectively guarantee the personal safety of operators in dry climate.           
 It is suggested that the inclination should not exceed 30 degrees in principle when the fall arresters is used for tilting operation. If the inclination is above 30 degrees, it is necessary to consider whether the fall arresters can impact the surrounding objects.           
 The key parts of the differential crash preventer have been specially treated for wear resistance and corrosion resistance, and have been rigorously debugged without adding lubricant.           
 Safety rope twisting is strictly prohibited. Disassembly and refitting are strictly prohibited. It should be kept in a dry and dusty place.           
 The precautions before the use of the purchased fall arresters for high altitude operation are as follows: due to environmental conditions or the presence of harmful substances, the chemical resistance and temperature requirements of the materials selected for the restriction of the use of the fall arresters; sensitivity to cutting and wear; degradation caused by ultraviolet radiation, the fall arresters is made before the first use. Manufacturer Certificate; Obtain guidance and training.           
 Before each use of the fall arresters, it needs to check the procedure; whether there is a label, whether the label is clear; scrapping criteria.           
 Our company produces fall-proof models include: speed difference fall-proof device, high-altitude fall-proof device, automatic control device, etc.           
 Principle of Anti-Fall Device: This product uses the difference of falling speed to control automatically, high hanging and low using.           
 Use Method of Anti-Fall Device: When in use, only need to cross the nylon suspension rope over the structure with strong and blunt edges above, hang the iron hook on the nylon rope onto the "n" ring, and hang the iron hook on the wire rope into the semi-circle of the safety belt to use. There is no need to replace the suspension point within the use radius. In normal use, the safety rope will flex freely with the human body. Under the action of the mechanism in the device, the operator is in a semi-tense state, which makes the operator feel free of concern. In case of a fall, the pull-out speed of the safety rope is obviously accelerated, and the lock system in the device is automatically locked. The safety rope is pulled out at a distance not exceeding 0.2 meters and the impact force is less than 2949N, which does no harm to the missing person. Load relief means automatic resumption of work. After work, the safety rope will be automatically recovered into the device for easy carrying.
