Types of Hydraulic Jacks | A Comprehensive Guide

Introduction to Hydraulic Jacks

What are hydraulic jacks?

Hydraulic jacks are mechanical devices that are used to lift heavy objects by applying force through a hydraulic mechanism. Unlike other types of jacks, hydraulic jacks use a fluid, usually oil, to generate and transfer force. This makes them more efficient and capable of lifting heavier loads compared to other types of jacks. The main components of a hydraulic jack include a pump, cylinder, and a piston. When the pump is operated, it creates pressure within the cylinder, causing the piston to move. As the piston moves, it exerts force on the object being lifted, allowing it to be raised off the ground.
