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

Mechanical screw jacks are widely used in heavy load lifting scenarios, especially where precise positioning is required. This 20 ton jack is suitable for building support and foundation work, bridge construction and reinforcement, railway construction and maintenance, as well as material handling in manufacturing and workshops.

Tips: How to maintain the screw jack?

1. Routine Inspection: Regularly check the screw jack for any visible damage, wear, or rust. Pay special attention to load-bearing parts such as the screw, nut, and bearings for cracks, distortion, or excessive wear.
2. Lubrication: Apply lubricant at recommended intervals to keep the screw and nut moving smoothly. Always use high-quality lubricants and follow the manufacturer’s guidelines regarding type and frequency.
3. Cleaning: Ensure the jack is kept clean and free from dust or debris that could hinder performance. Use a soft brush or cloth to wipe the screw, nut, and housing.
4. Proper Storage: When not in use, store the jack in a clean, dry environment. A protective cover can help shield it from moisture and dust buildup.
5. Respect Load Limits: Never exceed the rated load capacity. Overloading can damage the jack and create serious safety risks.
6. Professional Checkups: Arrange for periodic inspections by a qualified technician to confirm the jack remains in safe working condition and operates as intended.
