Do tripods need to be equipped with a bottom circular protective chain

A tripod is a device for lifting or jacking heavy objects, with two main functions: lifting and rescue. Generally, it is used in places such as tunnel entrances, hills, high-rise construction sites, fire pools, mines, deep wells, etc. It can only lift heavy objects from lower places to higher places and cannot be used as a tool for carrying heavy objects.

The tripod is composed of three plate supports. After installing the three supports on the upper part of the wellhead, it is necessary to install fixed chains between the supports to effectively prevent them from slipping. In addition, this chain is mostly made of stainless steel material, which has strong corrosion resistance and is very suitable for use at wellheads. Even in damp and rainy deep wells, it can maintain a smooth and beautiful appearance, and will not be easily corroded by external moisture, nor will it easily rust or break.

Therefore, the circular protective chain set at the bottom of the tripod can not only protect the lifting work of the tripod and prevent the three scaffolds from slipping, but also effectively extend the service life of the tripod.
