How to choose a suitable differential fall arrester?

Differential fall arrester is an anti fall device for high-altitude operation. It is used simultaneously with safety belt and safety rope (except for special requirements) and complements each other. The purpose is to provide adequate fall protection for high-altitude workers. The speed difference fall arrester has the function of helping the high-altitude workers stand and locate stably and realize the operation with both hands; In case of some misoperation, the safety goal of preventing falling from height can be effectively achieved, so that the high-altitude workers will not suffer casualties due to falling from height. So how to choose the products suitable for yourself?

First of all, choose fall arresters with different bearing capacity according to the actual demand. For example, if your demand is to bear 1 ton, then if you still choose 5mm thick steel wire rope, it obviously does not meet your demand.

Secondly, according to your working height, the fall arrester is hung high and used low. Therefore, you must choose different specifications of fall arresters according to your working height. For example, your working height is 20m. Obviously, you should choose a fall arrester with a specification of more than 20m.

Then choose webbing type fall arrester or wire rope type fall arrester according to your working environment. If your working environment requires insulated fall arrester, choosing webbing type fall arrester is your correct choice. Also, if you require light weight, then the webbing fall arrester will meet your needs.

Another important point is to ensure the quality. When purchasing, we must ensure that it is produced by regular manufacturers. The so-called regular manufacturers generally refer to having "two certificates and one qualified". The two certificates are the business license and production license. The first qualified is identified by the national testing institution and issued the identification report, and the identification results meet the requirements of gb24544-2009 standard.
