Human life today has made life much easier thanks to human progress throughout history, especially in the automobile industry. Humans no longer need to do anything to move heavy objects by themselves. Nowadays, you can use a crane to move heavy objects. A crane is one of the biggest machines that is used to move heavy objects. A crane is one of the most widely used machines in the automotive industry. Cranes are used in civil and construction projects. The crane has an Arabic root, and in Persian it is called Granbar.
Construction time
Cranes were built for the first time in human history about 4000 years ago. The first people who invented and used this machine were the Egyptians. In ancient Egypt, they used this machine to build their palaces and pyramids. The Egyptians at that time knew the crane by the name of Shadov. The first cranes were made of wood and one horizontal support and two vertical supports and a rotating arm.
Types of cranes
1) Tower crane (tower crane)
2) Machine crane (mobile crane)
3) Roof crane
4) Gantry crane
5) hanging crane
6) jib crane
Types of cranes and their use
The first crane, as we said above, is the tower crane. This type of crane is used in crowded environments. Weight is used for balance in this type of crane. In the tower crane, the traction is done by the tower instead of being transferred from the machine or mast to the ground. This type of crane is used in tower and bridge construction projects and skyscrapers, etc. One of the most important features of this type of crane can be the stability of the mast while doing the work. And the ability to rotate the load and the ability to raise and lower the load, as well as to adjust the working radius. There are generally two types of tower cranes: fixed and moving. Constants are divided into two categories at build time. fixed on the jack and fixed on the base.
The second crane is a machine crane or a mobile crane. In the fixed type of machine crane, they use a jack. The third type of crane is the overhead crane. This type of crane is divided into two categories during construction. One is a single bridge and two are double bridges. In English, this crane is called overhead crane. It is used to transport heavy objects vertically and horizontally in warehouses and industrial halls. The fourth type of crane and its application is the arm crane. These types of cranes are used in various industries. Boom cranes are divided into two categories at the time of construction. The first type is wall cranes and the second type is column cranes and each of them can be used for many cases. The fifth type of crane and its application is hanging crane. These types of cranes are used in places that are not very high. These types of cranes are made with a maximum capacity of five tons during construction, like in the automobile industry.
