On construction sites, screw jacks use their solid arms to support the backbone of modern architecture. This seemingly simple mechanical device is a symbol of strength in construction engineering.

Spiral jacks convert rotational motion into powerful linear thrust through precision machined trapezoidal threads. Each thread has been accurately calculated to ensure that it is still as stable as Mount Tai under the weight of hundreds of tons. When the worker shakes the handle, the screw slowly rises, and the steel beam weighing tens of tons smoothly lifts, showing an astonishing beauty of power.

At the construction site, the screw jack demonstrated extraordinary adaptability. Whether it is a narrow underground space or a high-altitude work platform, it can find its place of use. At the installation site of the steel beam, four jacks cooperated seamlessly to accurately lift the tens of meters long steel beam to the predetermined height; In the lifting operation of concrete slabs, it also transforms into a precise leveling tool, controlling the error within millimeters.

The reliability of a screw jack comes from its precise mechanical structure. The screws and nuts made of high-strength alloy steel undergo special heat treatment to ensure that they will not deform during long-term use. The self-locking design allows it to remain stable in any position, even if suddenly losing power, there will be no unexpected sliding. This reliability makes it the most trusted partner for construction workers.

From the ground to the clouds, spiral jacks have witnessed the rise of countless buildings. It is not only a symbol of power, but also a crystallization of human wisdom. In this era of mechanization, this seemingly simple mechanical device still writes its own legend in the history of architecture with its unique charm.
