Those safety fall arresters you don't  know how to use

 Our production and inspection of fall arresters is supervised by the director of the factory. However, our safety fall arrester has also been inspected by the professional department of Baoding City. The Baoding pull test experimental center is an independent testing unit. Our products are all tested by this unit correctly, and will not enter the market until the safety report is issued.            

 Our crash preventer products are enforced by European standards, as follows:           

 The movable fall arresters on the rigid support can automatically lock the movable fall arresters on the track or rope of the rigid support, and the loose force device can be added.           

 The mobile fall arresters on the soft support is automatically locked on the soft support (such as rope), and  the loose object can be added.            

 The rope of the fall arresters for aerial operation, which connects materials or components of an equipment, can be a rope, metal rope, belt or chain made of synthetic fibers, up to 2 meters in length.            

 Why is the abnormal noise during the use of the fall preventer?            

 As far as the fall arresters itself is concerned, there is no internal meshing mechanism which can produce noise because its internal operating parts are supported by two sliding bearings. The noise of wire rope fall arresters is mainly caused by bad meshing, interference and vibration impact between the gear of fall arresters when it runs up and down.            

 In summary, it is clear that if there is noise in the anti-drop device, it is most likely that the meshing between internal gears will occur the above phenomenon. Below is an understanding of the ideal operating environment of the purchased speed differential anti-drop device, how to approach the approximate ideal  working condition and how to better use the wire rope anti-drop device, the following points should be satisfied Requirement: 

 Firstly, the differential crash preventer meets the requirements of manufacturing  parameters, and the clearance between axle and radial is reasonable and flexible. 

 Secondly, the meshing clearance between the gears of the fall preventer meets the national standards.           

 Thirdly, the fall arresters should do pure rolling on the standard pitch rack of construction hoist.            

 Therefore, we remind you that most of the noise in the use of high-altitude fall arresters comes from the tight meshing gap, loose meshing position or unsatisfactory meshing position, and the resulting noise derivatives.            

 Except for the same technology and structure, the specifications and sizes of all parts of different specifications of high-altitude fall arresters are different. Most customers who buy anti-drop devices are generally referred to as wire rope sizes. For example, a 5-meter fall arresters of 1 ton or less is called a 5-meter fall arresters. RAMHOIST will popularize the specifications of fall arresters for you correctly, and only by referring to the correct specifications can you purchase the products suitable for you.

 The first way to judge the specifications of the fall arresters is:            

 Usually most people will use the wire rope fall arresters according to their needs. Wire rope length (human fall arresters, load less than 1000kg) to purchase. Its national standard specifications and classification standards are as follows: 3 meters, 5 meters, 10 meters, 15 meters, 20 meters, 30 meters.            

 The second way of judging the specifications of the fall arresters is:            

 If the carrying capacity is more than 1 ton, it is collectively called industrial heavy-duty fall arresters. The specifications of this kind of industrial fall arresters are divided according to its carrying capacity: for example, 300 kg,  500 kg, 1000 kg, 1500 kg, 2000 kg, 3000 kg, 4000 kg, 5000 kg.            

 According to the different carrying tonnage of the self-locking device, the length of the steel wire rope required by the national standard is as follows: 

  300kg, 500kg: 5m, 10m, 15m, 20m, 30m;           
 1000 kg: 1500 kg, 2000 kg: 5 m, 10 m, 15 m, 20 m;           
 3000kg:  5 meters, 10 meters, 15 meters, 20 meters;           
 4000kg:  5 m, 10 m;           
 5000kg:  5 meters.
