In the precise and grand engineering field of modern bridge construction, although the screw jack may seem inconspicuous, it is a key tool. Its main function is precise lifting and support - whether it is fine-tuning and positioning during the installation of prefabricated beam sections or stable support for cast-in-place formwork systems; Whether it is the smooth lifting during bridge bearing replacement or the safe top support during local structural maintenance, its reliable figure can be seen.

Compared to other types of jacks, the advantages of screw jacks are particularly significant. Its mechanical self-locking feature provides unparalleled safety, even in the event of prolonged load-bearing or power interruption, the load can be firmly locked, greatly reducing the risk of accidental settlement. At the same time, it allows construction personnel to perform extremely precise displacement control, achieving millimeter or even sub millimeter level adjustment through rotating screws, which is crucial for ensuring the accuracy of bridge alignment and force balance. In addition, its structure is sturdy, has low environmental requirements, is easy to maintain, and exhibits strong adaptability and durability in complex construction sites.

It can be said that the screw jack is a powerful tool in the hands of bridge engineers to overcome hardness with softness. With its outstanding characteristics of precision, reliability, and safety, it plays a decisive role in the subtle aspects that require strict precision and stability, silently guarding the key process of every bridge from foundation to closure. It can be regarded as the "solid force" that cannot be ignored behind the support of the Hongda Bridge.
