Spiral Jack
- Commodity name： Spiral Jack
Keywords:
Jack Series
- Product Description
-
A screw jack is a lightweight and compact lifting device that utilizes the principle of helical transmission to achieve vertical movement. It is primarily used in scenarios such as vehicle maintenance, equipment installation, construction support, and heavy-load adjustments. By manually turning the handle, the screw assembly is driven into motion, converting rotational movement into linear lifting or lowering action, thereby enabling the lifting or lowering of heavy objects. The structure of a screw jack mainly consists of a base, a screw rod, a nut (fixed either on the base or the top cap), a top cap, and a handle. The base provides stable support, while the top cap makes direct contact with the load. When the handle is turned, the screw rod rotates within the nut and moves vertically, lifting the load accordingly. Typically, screw jacks can lift weights ranging from 1 ton to 50 tons, and their compact design allows them to operate effectively even in low-clearance spaces.
The spiral jack is distinguished by its simple structure and high reliability, eliminating the risk of oil leakage common in hydraulic systems. It also boasts low maintenance costs and features a self-locking mechanism—thanks to the inherent self-locking property of the screw pair, the screw rod will not descend on its own even when the handle is released, ensuring stable support for heavy loads and enhancing safety. This feature makes it particularly suitable for scenarios requiring long-term support of heavy objects, such as providing secure stabilization during equipment maintenance. In addition, the compact size and lightweight design make it easy to carry and store, allowing flexible use even in confined spaces. Some models are crafted from alloy steel, offering excellent wear resistance and impact strength, enabling them to handle substantial loads effectively. The lifting cap is typically designed with a rotating or anti-slip textured surface, ensuring firm contact with the load and preventing slippage during operation.Primarily used in fields such as automotive maintenance, mechanical manufacturing, construction engineering, and bridge construction. It operates by rotating a handle to drive an internal screw mechanism for lifting and lowering, enabling precise control over the height of heavy objects. This tool is particularly suitable for lifting operations conducted in environments without access to power sources, such as vehicle chassis repairs, equipment installation and debugging, and supporting large structural components.
