Manual Worm Gear Screw Jack

The Manual Worm Gear Screw Jack is a reliable lifting device driven by a precision worm gear mechanism, featuring a built-in self-locking function that keeps the load securely in place even when the operating force is removed. It converts the rotary motion of the hand crank into stable linear lifting movement, delivering precise, fine-tuned height adjustment at a slow, controllable pace. Compact in structure, lightweight and easy to install, it can operate stably without electricity, making it ideal for intermittent positioning tasks, emergency actuation, and scenarios where power supplies are inconvenient or unavailable. Widely applicable in machinery maintenance, metallurgy, water conservancy, chemical engineering and other industries, this jack supports customized lifting heights, works reliably within a temperature range of -20℃ to 100℃, and offers a long service life with high stability and safety margins for heavy-load operation.
