There are various structural forms of screw jacks

The structural forms of screw jacks include various types, such as single-column, double-column, multi-column, wall-mounted, and scissors types. Single-column screw jacks feature a simple structure and are suitable for smaller workspaces; double-column screw jacks offer greater stability and load-bearing capacity; multi-column screw jacks are designed for larger workspaces and higher load-bearing requirements; wall-mounted screw jacks can be directly installed on walls to save space; while scissors-type screw jacks provide greater lifting height and enhanced stability.
