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.
5. Before loosening the screw jack to make a heavy object land, it is necessary to check beforehand whether the heavy object has been supported firmly and then release it slowly so as to ensure safety.
6. Butter shall be used for lubrication during storage to prevent excessive wear and reduce service life.

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: Types of Jacks

• Hydraulic Jacks: These use hydraulic pressure to lift heavy loads. They are often used for lifting vehicles in automotive repair, as well as for lifting heavy machinery and equipment.
• Bottle Jacks: These are a type of hydraulic jack that is shaped like a bottle, with a wide base and a narrow neck. They are commonly used for lifting heavy loads in tight spaces.
• Floor Jacks: These are also a type of hydraulic jack that is designed for use on a level surface. They are often used to lift vehicles for tire changes or other repairs.
• Scissor Jacks: These are compact jacks that use a scissor-like mechanism to lift loads. They are often used for lifting vehicles and other light loads.
• Screw Jacks: These use a screw mechanism to lift heavy loads. They are often used for supporting and lifting heavy machinery and equipment during maintenance or repair operations.
• Pallet Jacks: These are a type of manual jack that are used to move heavy loads on pallets. They have a fork-like mechanism that slides under the pallet, allowing the load to be lifted and moved.
• Transmission Jacks: These are specialized jacks designed for lifting and supporting vehicle transmissions during maintenance or repair operations.
