Mechanical jack is another name for screw jack. The obvious difference between it and hydraulic jack is that it does not have oil.The oil jack can only be used upright, so it is also called a vertical hydraulic jack, while the screw jack can not only be used upright, but also upside down.Mechanical jacks are mainly used for lifting objects, and are used in engineering operations such as automobile manufacturing, factories, pipeline construction, airport construction, and bridge construction. They are formed by a casting process, and the main body is made of ductile iron.
