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: Screw Jacks vs. Hydraulic Jacks

Screw jacks and hydraulic jacks are both widely used to lift heavy loads, but they have several important differences:

• Load Capacity: Screw jacks typically support heavier loads compared to hydraulic jacks, owing to their more robust construction and ability to handle larger weights.
• Precision: Screw jacks offer greater precision in positioning the load, as the screw thread allows for small, easy adjustments. In contrast, hydraulic jacks can be harder to position accurately due to the fluid dynamics of the hydraulic system.
• Efficiency: Screw jacks are highly efficient, utilizing the mechanical advantage of the screw thread to lift heavy loads with minimal effort. Hydraulic jacks, however, require more energy since the hydraulic fluid must be pressurized to generate the necessary force.
• Maintenance: Screw jacks demand minimal maintenance, which reduces downtime and enhances productivity. Hydraulic jacks, however, require more upkeep, such as regular checks on hydraulic fluid levels and periodic fluid replacement.
• Safety: Screw jacks are generally safer than hydraulic jacks, as they don't rely on hydraulic fluid, which can pose a hazard if it leaks.

In general, both screw jacks and hydraulic jacks have their respective benefits and drawbacks. The decision to use one over the other depends on the specific requirements of the task at hand. Screw jacks are typically favored for heavy-duty lifting tasks that demand accurate positioning, while hydraulic jacks are commonly chosen for situations where speed and convenience are the top priorities.
