Tips for Using a Screw Jack

1. Before use, it should check whether the parts are intact, make sure that the screw, nut, rocker, etc. are not damaged or stuck, and add lubricant to reduce wear and tear and guarantee smooth lifting and lowering.

2. The jack should be placed vertically on the solid and flat ground, shaking evenly during operation, and impact is strictly prohibited. Before lowering, it must be ensured that the weight has auxiliary support, and the operation should be slow and smooth to prevent slipping.

3. It is strictly prohibited to use it beyond the rated load, and the jacking height shall not exceed the warning line or two-thirds of the total length of the screw to prevent the accident of dislodging.

4. When multiple units are used at the same time, synchronization should be maintained to avoid tilting of heavy loads. Regularly clean, inspect, and store in a dry place after use to prevent rust and corrosion.

5. The use of self-lowering jacks needs to confirm the status of the brake, and pay attention to the protection of the operation to avoid the rapid fall caused by personal or equipment damage.

6. Butter shall be used for lubrication during storage to prevent excessive wear and reduce 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.
