Claw jack is a special existence among all types of jacks. It has both a high top and claw parts located at the support. Therefore, the jack can be used for both ordinary heavy lifting work and low and heavy lifting work. However, it should be noted that the load-bearing capacity of the jack claw is only half of the top, and it must not be overloaded for use.

The claw and top of the claw jack are made of the same steel plate and are welded together without any cuts, with a very strong load-bearing capacity. Why is the load-bearing capacity of the claw only half of that of the top?

In fact, this is related to the support and backing of the lifting part. Below the top is the entire body of the jack, which provides a solid backing for the top. However, when the claw lifts, lifts, and supports heavy objects, there is no support below it. Without the backing support, it can only rely on the force of the entire steel plate and the partial support provided by the body, and the load-bearing capacity of the claw will be greatly reduced.
