Tips for Using a Screw Jack

1. Before lifting a heavy object, pay attention to the position of the jack so that it remains vertical to prevent the screw from bending and causing accidents.
2. When loading, force should be used to shake the handle evenly, so as to avoid accidents and damage to the screw jack caused by up-and-down impact.
3. When in use, care should be taken not to exceed the maximum load-carrying capacity allowed to prevent accidents caused by overloading.
4. When in use, the lifting height shall not exceed the marking line on the sleeve or piston, and for the jack without the marking line, the lifting height shall not exceed 3/ 4 of the total height of the screw clasp or oil plug, so as not to remove the sleeve or piston top, Damage the Jack and cause an accident.

Applications

A screw jack, also known as a mechanical screw jack, is a device that is used to lift heavy loads vertically by converting rotational motion into linear motion, widely used in a variety of applications where heavy loads need to be lifted, such as in building support, bridge construction, and material handling. 

Tips: How to maintain the screw jack?

• Regular inspection: Perform regular visual inspections of the screw jack to check for any signs of damage, wear, or corrosion. Check the load-bearing components such as the screw, nut, and bearings for any cracks, deformation, or signs of excessive wear.
