Worm Gear Jack

The worm gear screw jack is a precision linear lifting actuator designed based on the principles of worm gear and trapezoidal screw transmission. Classified as a general-purpose industrial heavy-duty lifting component, it is also commonly referred to as a screw jack, spiral lift, or mechanical lifting jack. The device operates by using a worm to drive the rotation of a worm gear, thereby converting rotary motion into the linear reciprocating motion of the screw shaft. Capable of precisely executing industrial tasks such as lifting, jacking, fine adjustment, clamping, and tilting, it serves as a core component in automated production lines, heavy machinery, and precision tooling systems.

SWL Series Trapezoidal Screw Jack (General-Purpose Heavy-Duty Type)
A classic, industry-standard model featuring a high-precision trapezoidal screw assembly and a tin-bronze worm gear mechanism. It excels in high-load capacity, stability, and self-locking performance, making it ideal for low-speed, low-frequency, and heavy-load applications. Offering excellent cost-effectiveness and ease of maintenance, it is the preferred choice for standard industrial lifting operations. With a load range of 0.5T to 120T, it meets lifting requirements for everything from small-to-medium machinery to heavy-duty metallurgical equipment.

- Mechanical Self-Locking for Worry-Free Safety
Utilizing a high-reduction-ratio worm gear drive combined with the self-locking characteristics of a trapezoidal lead screw, the system automatically locks the load during power outages or shutdowns. This prevents sliding or falling without the need for additional braking devices, significantly enhancing operational safety and eliminating hazards associated with heavy-load operations.

- Quiet, Efficient, and Smooth Operation
Precision gear grinding optimizes the backlash between the worm and gear, ensuring smooth, snag-free transmission and keeping operating noise as low as 55–65 dB. The mechanical drive offers stable efficiency and low energy loss; unlike hydraulic systems, it requires no continuous energy input, resulting in significant long-term energy savings.

- Controllable Precision and Accurate Fine-Tuning
Free from issues such as hydraulic oil leaks or pneumatic pressure fluctuations, the purely mechanical drive ensures precise positioning and enables millimeter-level fine adjustments. With high repeatability, it fully meets the high-precision lifting requirements of precision tooling, inspection equipment, and automated assembly lines.
