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.
