Self-testing Method for Reliability of Fall arresters

 In order to ensure that our fall arresters can achieve safe operation of the good state will be sold to customers.            

 Before putting into use and after a certain time limit, the user needs to carry out corresponding tests to confirm the performance status of the fall arresters.           

 Usually, the test of fall arresters includes no-load test, static load test, rated load test and so on. The pertinence of each experiment is different.            

 Simply speaking, no-load test is to confirm whether the working mechanism of the fall arresters operates normally under no-load condition, whether the sensitivity and effectiveness of the control system and safety device meet the safety

 requirements, and the rest of the detection mechanisms, as well as static and dynamic load-bearing capacity test of the fall arresters, are also to test the finished product performance of the fall arresters.            

 The simple understanding of dynamic load test is to test the performance and parameters of the fall arresters under the condition of lifting operation. In order to ensure the authenticity and reliability of the crash preventer test results, the dynamic load test often needs to continue for at least one hour. Usually, the larger the tonnage of the fall arresters, the longer the test  time.            

 The main method of inspection for the hook of the fall arresters is usually visual inspection, that is, to observe carefully with a magnifying glass, and, if necessary, to use coloring or flaw detection.            

 The wear of dangerous section can be measured by calipers or calipers to compare the dimensions measured by calipers with the opening of standard hooks of original size.           

 RAMHOIST introduces a simple and applicable method: the newly disassembled high-altitude fall arresters, the material of safety hook, whether there are cracks in the hook, whether there has been torsional deformation can be visually measured, also can be measured by the side of the steel ruler, when the requirement is accurate, it can be detected by the marking ruler on the platform.            

 The relative landing height of the rope catcher of the fall arresters to the brake rope is strictly prohibited to exceed 100 mm. At the same time, when the cage of the fall arresters pulls heavy objects, the length of the buffer rope must be 1-1.3 times as high as the free landing height of the safety fall arresters rope catcher.            

 Meanwhile, the falling height of the cage of the safety fall arresters to the derrick is strictly forbidden to exceed 400 mm.            

 Finally, after the decoupling test of the safety fall arresters, it is necessary to inspect all parts comprehensively. It must be complete, firm and reliable. There is no unconventional phenomenon, that is, it is safe and reliable before  it can be put into use. Safety fall arresters must be equipped with buffer equipment, and ropes without buffer should not be used for anti-fall braking  equipment. The reason is that when a person or object falls from a high place,  the buffer equipment will weaken the force of the moment of falling by more  than 60%, so as to prevent the phenomenon that the safety rope will be broken due to the excessive force of the moment of falling.            

 The falling brake components of the buffer equipment of RAMHOIST Safety Fall arresters can reduce the impact force of falling brake at high altitude and ensure safe braking.
