What is the primary use of a bar screw jack?

Bar screw jacks are used for temporary stabilization in rescue and stabilization operations. The screw mechanism lets you raise or lower a load a little at a time, and extension bars help reach into tight spaces. In practice, rescuers place the jack under or beside a collapsed member and twist the screw to lift and hold that member in a controlled position while cribbing or shoring is set up. This stabilization is essential to prevent further movement and create a safer working area for victims and rescuers. While they can contribute to lifting, their primary purpose is to provide support and stabilization, not performing heavy lifting operations, pushing or pulling loads, or replacing wooden cross braces during trench rescue.
