Types and Usage Methods of Jacks 1 Kangwang Cultural University

Zhejiang Kangwang Company Jack Academy: Jacks are classified by manufacturing principles into several types, including mechanical jacks and hydraulic jacks, each with different principles.

Thus, in a balanced system, the pressure applied on a smaller piston is less, while the pressure on a larger piston is greater, maintaining the fluid's static state. 2.
