Spiral jacks have different load-bearing capacities, and the lifting work faced by different specifications of spiral jacks is also not the same. Below, we will take a look at which working environments different rated load spiral jacks are suitable for.

The lifting tonnage of a screw jack is relatively large, generally ranging from a few tons to several hundred tons.

Firstly, screw jacks weighing around 3 to 10 tons are generally suitable for smaller and lightest goods, mainly for automobile maintenance, with a lower safety index, but they are very convenient to use.

Secondly, there are screw jacks weighing around 10 to 50 tons, which are commonly used in railway axle lining replacement and bridge structure installation support points, and are mostly purchased in bulk.

Finally, there is a hundred ton screw jack with exaggerated rated load. This type of screw jack is commonly used in the construction of highway bridges due to its strong load-bearing capacity.

The above are the different working environments faced by screw jacks of different specifications.
