Spiral jacks play a crucial role in large-scale pipeline installation projects. The installation of large pipelines is complex and delicate, requiring not only precise placement of heavy pipelines, but also ensuring perfect docking between pipelines, which places extremely high demands on installation equipment and technology.

The structure design of the screw jack is exquisite, consisting of main components such as screw, handle, base, nut sleeve, etc. At the pipeline installation site, workers first firmly place the jack base on a solid ground to ensure that the entire device is stable and not shaking. Subsequently, align the top of the sleeve with the support point of the pipeline, rotate the handle, and the transmission device drives the spiral rod to rotate. Through threaded engagement, the rotational motion is converted into a linear rise of the sleeve, easily lifting the pipeline. Due to the self-locking characteristic of spiral transmission, workers can stop and adjust at any time during the lifting process, and the pipeline will be stably stopped at the required height.

During the installation process, the angle adjustment and precise docking of the pipeline are key steps. By using a screw jack, workers can finely adjust the angle of the pipeline by adjusting the handle according to the actual situation, ensuring that the pipeline joints are tightly sealed. During the docking operation of multiple pipelines, multiple screw jacks work together to support and adjust the pipeline from different positions, ensuring the straightness and concentricity of the pipeline installation.

Spiral jacks have strong load-bearing capacity, good stability, and can easily handle the weight of large pipelines. They are easy to operate and do not require complex training, making it easy for workers to get started. At the same time, it also has self-locking function, which can support the pipeline for a long time, making it convenient for workers to perform subsequent fixing and welding operations. In the field of large-scale pipeline installation, the screw jack has become a powerful assistant to ensure the smooth progress of the project with its own advantages.
