What is the reason for the noise during the use of the fall arresters?

Firstly, it is suggested to consider whether the copper sleeve in the structure of the safety fall arrester has been excessively worn out. Even if the copper sleeve is worn seriously, We does not recommend that you dismantle the fall arresters products and replace the components without authorization, which will bring hidden dangers to your safe use.The causes are as follows: 1. Use, maintenance and mode of the fall arresters.Improper; 2. The quality of products can not be strictly checked before the purchase of fall arresters.          

 Secondly, the production process of crash preventer is not strict. During assembly, the internal dimension error of steel rope crash preventer is too large,resulting in bad occlusion between the gear of crash preventer and the rack of elevator, accelerating wear and tear, and generating noise when the clearance is too large.            

 The second situation is evident in the inferior crash preventer products, and similar situation will appear shortly after use. This situation is difficult to solve.There is a hard injury in the crash preventer you purchased. If you buy the high-quality manufacturer crash preventer, you can ask for replacement products. RAMHOIST needs to test new products to replace new products. For many years, we have been adhering to the spirit of perfect after-sales service and offering more high-quality and low-cost lifting products to our customers.            

 The first important component to check the fall arresters is the catcher. Check whether all parts are complete, whether there are breakage cracks and other defects, whether the connecting parts are loose and lost; Check whether the wedge surface of the fall preventer is clean, ensure good lubrication, and whether foreign bodies fall into the catcher; Check the wear condition of the  guide bushes of the fall preventer, whether the fall preventer has exceeded the limit wear degree, and the maximum wear on each side of the bush. Allow wear 3MM, excess value must be replaced, in order to prevent the catcher from being  abraded to check whether the driving spring of the fall arresters is damaged or not, the reliability of the spring fixing and whether there are foreign bodies  hindering the spring expansion; what needs to be noted is that the anti-falling brake rope and the fall arresters tensioning device are checked, and the anti-falling buffer device is checked to see if there is loosening. The situation of movement.            

 In recent years, the noise problem of safety crash preventer is more prominent. The causes of the noise of safety crash preventer are related to design, manufacture, installation, debugging, use and maintenance, etc.The analysis of noise should also start from such aspects. As far as it is concerned, there is no internal meshing mechanism which can produce noise because its internal operating parts are supported on two sliding bearings.Therefore, the noise of speed difference fall arresters is mainly caused by bad meshing, interference and vibration shock between the gear and rack of safety device when the construction hoist hanging cage is running.            

 The high-altitude fall arresters should meet the following requirements: first, the fall arresters meets the requirements of manufacturing parameters, the axle and radial clearances are reasonable and flexible to rotate; secondly, the meshing clearance between gear and rack meets the requirements of specifications; thirdly, it should do pure rolling on the standard pitch rack of construction hoist.            

 The noise sources of safety devices need to be checked: first, the manufacturing accuracy of the whole machine; second, there are welding errors in the assembling of the ear plate safety device installed with the bottom plate of the fall arresters on the suspension cage girder, resulting in the non-vertical installation of the bottom plate of the safety device, affecting the normal meshing relationship of the anti-falling safety gear and inducing noise; third, safety should be checked at this time. Whether the bottom plate is parallel to the rack; Fourth, whether there is zero error on the back of the welding after the safety device is installed and processed.
