On busy construction sites, screw jacks silently shoulder the heavy responsibility of equipment installation. This seemingly simple device contains intricate mechanical principles. It consists of a base, a screw, a nut, and a handle. By rotating the handle, the screw can be lifted and lowered to achieve precise height adjustment.

During the equipment installation process, the construction personnel first need to place the screw jack on a sturdy and flat base. As the handle rotates, the screw slowly rises, and the top load-bearing plate steadily supports the equipment. At this point, the construction personnel will use a spirit level to repeatedly measure and adjust the height of each jack to ensure that the equipment reaches a perfect horizontal state. The whole process requires patience and meticulousness, just like playing a precise mechanical symphony.

The advantage of a screw jack lies in its excellent stability and precision. Compared with hydraulic jacks, it does not experience settlement problems caused by oil pressure leaks and can maintain a stable support state for a long time. When installing large steel structures, multiple screw jacks work together to accurately lift tens of tons of steel beams to designated positions.

Special attention should also be paid to safety when using a screw jack. Overloading may cause deformation of the screw, and sudden impact loads may cause equipment instability. Therefore, construction personnel must strictly follow the operating procedures to ensure that every step is foolproof.

In modern construction, the screw jack is not only a simple lifting tool, but also an important guarantee for ensuring project quality. Every precise leveling is a perfect interpretation of the craftsmanship spirit, laying a solid foundation for the safety and reliability of the building.
