What preparatory work should be done before installation of fall arrester

 The period of profit and loss is not only in heaven, but also in eternal happiness. Correct installation, rational use and timely maintenance of the fall arrester are conducive to its normal and reliable capture, smooth braking function and prolong its service life. So, what preparations do you need to do before installing the fall arrester? The professional technicians of the crash preventer manufacturer company are here to tell you the preparation work before the installation of the crash preventer. 

 Firstly, the sample is made according to the shape and size of the cross section of the fall arrester to inspect the wellbore at a speed of 0.3/s; the minimum gap between the most prominent part of the fall arrester and the wall of the tank and track beam must meet the relevant provisions of Articles 385 and 387 of the "Coal Mine Safety Regulations". If it does not meet the requirements, it must be dealt with. The debris in the wellbore should be removed.            

 Secondly, remove bottom hole water and debris.            

 Next, the length of the brake rope corresponding to the depth of the well is intercepted, and one end of the brake rope is tied up and repaired to avoid loosening, easy to install and fix. When intercepting, attention must be paid to the spare length of not less than 5 m at the lower part of the fixed beam.            

 Finally, the containers and heating equipment for melting pasteurized alloys are  prepared.           

 With the development of China's economy and the rapid rise of the real estate industry, safety production is the most important issue, so the construction elevator fall arrester is a good escort to safety issues.            

 The construction elevator fall arrester adopts the original "double locking device" structure, which has stable locking, high safety factor and good reliability, and effectively solves the accidents caused by the impact of other objects due to the large rolling amplitude of the tilting operation.            

 The control system of the fall arrester adopts special steel and is specially treated. It is light in weight, wear-resistant, corrosion-resistant and  impact-resistant.The shell is made of aluminium alloy, which is light in weight and ageless. The safety rope is made of aviation steel wire rope. The suspension rope and seat belt are all flame retardant and can withstand high temperature of 200 C.            

 Fall arrester is a very important safety device. It has the function of restricting the over-speed operation of suspension cage. It can prevent and eliminate the falling accident of suspension cage due to over-speed operation. The function of fall arrester can effectively guarantee the safety of staff. For the choice of construction elevator fall arrester, we should find a company with great strength, which has good reputation and guaranteed products.            

 The fall arrester presses the button marked with "falling test" and does not let go. At this time, the electromagnetic brake loosens the brake and the cage falls down. When the falling speed reaches the calibrated action speed of the anti-falling safety device, the anti-falling safety device acts quickly and stops the cage on the guide rail frame. Normally, the braking distance of the suspension cage should be 0.3-1.2m from the start of the fall arrester to the stop of the suspension cage (excluding the free sliding distance of the suspension cage).            

 The braking distance of the fall arrester is measured and calculated by the following method: S: braking distance m m L: indicating pin end displacement mm m: gear modulus Z: gear teeth number. In addition, the measured L value is more than 8 mm. For the sake of safety of operators, it should be replaced. It is also a reminder that this test should be carried out every three months.
