Types and Usage Methods of Jacks 1 Kangwang Cultural University

Zhejiang Kangwang Company Jack Academy: Jack According to the manufacturing principle there are mechanical jacks and hydraulic jacks and several others, each with different principles. From the perspective of principles:

1. Hydraulic transmission The most basic principle it is based on is Pascal's principle, which means that the pressure of a liquid is consistent everywhere, so in a balanced system, the pressure applied on the smaller piston is relatively small, while the pressure applied on the larger piston is relatively large, which can keep the liquid stationary.

2. The basic principle of the mechanical jack is to transmit power through a screw, transferring power to the lever arm, engaging the teeth on the lever arm, thereby lifting and lowering the lever arm. The power transmission is reliable, with excellent self-locking performance and safety, but its weight is generally not large, around 1 to 5 tons.

A jack is a simple lifting device with a small lifting height (less than 1m). It has two types: mechanical and hydraulic. Mechanical jacks are further divided into rack-type and screw-type. Due to the relatively small lifting capacity, they are easy and safe to carry and operate, generally used for vehicle and mechanical maintenance work. Hydraulic jacks usually have a large lifting capacity, suitable for heavy machinery. Their disadvantages are limited lifting height, slow lifting speed, and special attention must be paid to hydraulic oil leakage.

Kangwang Company reminds you to pay attention to safety when using jacks.
