Why do most fall arresters use aluminum shells

Time:2025-07-07 16:42:45 Click:128

At present, the shell of the anti fall device mainly adopts two materials, one is polypropylene shell and the other is aluminum shell. And with a large number of aluminum shells, what are the main advantages of using aluminum shells for fall arresters?

Firstly, the density of aluminum casing is lower than other metals, and it is lighter in weight. From this perspective, high-altitude workers will not have a significant negative impact when using it.

Secondly, aluminum shells have excellent casting performance and strong plasticity, which is a major advantage for producers.

Thirdly, aluminum has stable chemical properties, is non-magnetic, and can be recycled and reused, making it a benign and recyclable metal material.

Fourthly, aluminum has excellent ductility and can be made into lightweight alloys with many metal elements, making it a superior material.

The above four points are the advantages of aluminum shell anti fall devices, which is also an important reason why most anti fall devices currently use aluminum shells.
