Crane
Crane is a machine that is used to move objects from one place to another such as raising, lowering and moving horizontally and vertically. The word (crane) in English means a crane, as mentioned at the beginning; The word crane refers to a machine that moves or lifts heavy objects by means of an arm (wire, cable, rope, etc.). As a result, machines that have a mechanism different from what was said; And they shake things in another way; They cannot be considered a crane. A crane is actually a type of machine, mast or high structure that is used by ropes and pulleys to raise or lower objects. This device uses one or more simple machines to create a mechanical advantage and thus move loads beyond the natural ability of a human being. Cranes are usually used in the transportation industry for loading and unloading or for moving objects. They are mainly used in the construction industry or other huge structures. Cranes used in the construction industry are often temporarily installed, and of course, they can also be installed on the ground or on special vehicles.

مان Applying today's cranes
Today, machines play a significant role in human life, and progress in industries and construction is almost impossible without machines. But this point should be considered that the machine should always be at the service of man and not the man at the service of the machine.
The daily life of people will be disrupted without cranes and it is somehow dependent on cranes. A clear example of this can be found in elevators. It is an example of a crane that today's modern life depends on. In fact, moving heavy objects is beyond the natural ability of humans, and humans use these machines both in industry and in construction projects such as: Dam Construction, tower construction, bridge construction... They have been able to solve a large part of the problems of human society with these machines, so these cranes have different types according to their efficiency and places of use and the capabilities they have.
