Spiral jacks rely on the transmission of force through spiral pairs, which makes them significantly different from hydraulic jacks. In addition to their different operating modes, the two are also vastly different in terms of component composition, with the screw jack containing more complex mechanical components inside.

The internal structure design of the screw jack is extremely precise, and each component plays its own role in a specific and appropriate position, playing an indispensable and important role. So, when the screw jack malfunctions, do we need to disassemble it ourselves and carry out maintenance on its internal components? The answer is negative.

The correct approach when encountering a jack malfunction is to seek the help of professional maintenance personnel and never disassemble it without authorization. This is because the internal components of the screw jack are precise and complex, and the structural layout is compact and tight. Even a slight deviation may cause irreparable damage to this precise and compact structure, which not only cannot effectively repair the fault, but may even cause more serious problems, resulting in the complete scrapping of the jack, affecting the normal progress of related operations, and may also bring potential safety risks.
