**Absolute Self-Locking:** Thanks to the friction angle principle of screw drive, it achieves mechanical self-locking at any lifting height, eliminating the need for additional braking devices and ensuring absolute safety during long-term support.
**Precise Control:** The lifting height is strictly proportional to the number of rotations, allowing for millimeter-level precision adjustments, which is crucial in equipment installation, alignment, and calibration.
**Strong Environmental Adaptability:** Unaffected by extreme high or low temperatures, it performs stably in frigid, high-temperature, or flammable and explosive environments where hydraulic jacks may fail or leak.
**Simple Maintenance and Long Lifespan:** A purely mechanical structure with no seals or hydraulic oil, resulting in a low failure rate. Daily maintenance requires only simple lubrication and cleaning, leading to an extremely long service life.
