Features

• Structural stability: The integrated body design enhances the overall strength and improves the stability and safety in the process of use.
• Jacking limit: The red line on the screw is the maximum jacking height indicator line, it is strictly prohibited to continue operation beyond this position to avoid danger.
• Anti-corrosion process: The surface of the multi-layer primer is treated by high-temperature baking, with good anti-corrosion properties, making it easy to paint, rust, and extending the service life.
• Scope of application: This manual screw jack does not apply to automobile jacking operations, please choose the use of reasonable scenarios according to the type of equipment load.
• Operation specification: Overloading is strictly prohibited; the threaded parts should be kept clean before and after use and lubricated regularly to ensure smooth operation.
• Restrictions on use: This product is only used for short-term jacking, not a substitute for support tools, and shall not be used for long-term load-bearing static use.

Details

1. The cast iron top cover: Quenched for durability and reliability.
2. The jacking sleeve: 45# stainless manganese steel is used to achieve durability.
3. The integrated cast iron: Forged for a high safety coefficient.
4. The handle: A handle of humanized design, which is easy to carry.
5. The ratchet wheel: Being engaged securely, it is not easy to fall off.
6. The base: The base, which has a larger thickness, ensures stable operation.
7. The control handle: The pinion in the rocker bar moves freely and stably, which provides ease in operation.

Use Methods

3.2T-25T:

For small-tonnage jacks, when lifting, the control cylinder needs to be lifted and rotated 180°, and when lowering, the cylinder should be lifted and rotated back to its original position.

32T-200T:

For large-tonnage jacks, when lifting, simply press the control cylinder to the other end. When descending, simply return the cylinder to its original position to complete the descent.

Tips for Using a Screw Jack

• Before lifting a heavy object, ensure the jack is placed upright to avoid screw bending and potential accidents.

• When operating, shake the handle with a steady, even force to prevent impact damage and ensure safe use.

• Do not exceed the jack’s rated load capacity, as overloading can easily cause accidents.

• The lifting height must stay within the marked line on the sleeve or piston; if unmarked, it should not exceed three-quarters of the total screw or piston height to prevent parts from coming loose and damaging the jack.

• Before lowering the load, confirm that it is securely supported, then release the jack slowly to guarantee safety.

• Apply grease for lubrication during storage to reduce wear and extend the jack’s service life.

Applications

A manual screw jack, also referred to as a mechanical screw jack, is a device designed to lift heavy loads vertically by converting rotational motion into linear motion. It is commonly used in various applications that require lifting heavy loads, including building support, bridge construction, and material handling.

Tips: What is a Manual Screw Jack?

A manual screw jack is a device designed to lift heavy loads vertically by converting rotational motion into linear motion. It operates through a screw mechanism turned by a handle, which raises or lowers a load-bearing platform.

These screw jacks are commonly used in applications requiring heavy load lifting, such as in manufacturing, construction, and material handling. They are particularly useful for supporting and lifting heavy machinery and equipment during maintenance or repair tasks.

One of the key advantages of mechanical screw jacks is their simplicity and reliability. They don't rely on electricity or complex hydraulic systems, making them easy to use and maintain. Furthermore, they can be customized to meet specific lifting needs by adjusting the screw size, thread pitch, and gear ratio to accommodate various load and travel requirements.
